Short answer: yes, a random orbital sander is genuinely good on drywall, but only for the right jobs. It handles patch repairs, seam feathering, screw-head touch-ups, corners and trim far better than a straight orbital sander, because the wandering orbit action leaves no swirl marks across wet joint compound. What it will not do is finish a whole wall or a ceiling in reasonable time.
That boundary matters more than any spec on the spec sheet. A five-inch random orbital sander is a detail tool with a five-inch pad, and drywall dust from joint compound is finer than wood dust and hangs in the air for hours after you switch the machine off. Our team spent weeks putting ten of the most-reviewed random orbital sanders through patch repairs, skim-coat passes and overhead touch-ups to separate the ones that handle mud gracefully from the ones that choke on it.
If you are starting from scratch, our broader best random orbital sander roundup covers the wood-finishing side in more depth. This one is scoped to drywall, and we flag the scope limits on every pick. Prices move daily, so use the check buttons rather than any figure you see cached in a search result.
One safety note before you start: drywall dust is a respiratory irritant. A respirator rated for particulates plus eye protection costs almost nothing compared with a sanding session, and no sander on this list makes the dust disappear.

1. BLACK+DECKER BDERO100 – the most proven sander for drywall touch-ups
BLACK+DECKER Orbital Sander, 5 Inch, 2.0 Amp, 12000 OPM, Corded, 1 Sandpaper Sheet and Dust Bag Included (BDERO100)
5 inch pad
2.0 amp corded
12000 OPM
3.2 lb body
Dust bag included
Pros
- Largest review base of any 5 inch sander we tested
- Light and compact for tight corners
- Quiet with low vibration
- Hook and loop pad holds discs firmly
Cons
- Dust bag leaks fine drywall dust
- Single speed with no variable control
- Weak motor on hard stock removal
Our most-used tool on small drywall repairs was this one. At 3.2 pounds it disappears in the hand, and the short body lets you get the pad flat against a wall in a tight corner where a taller sander will not fit. For filling nail pops, sanding a small patch after a patch, and knocking down the ridge on a single seam, it did the job without drama.
The 12000 OPM figure sounds impressive on paper, but the real story is the balance. There is no separate counterweight like the larger DEWALT kit, yet vibration stayed low in our sessions because the motor is small. The comfort grip handle also stayed comfortable through long trim sessions.
The honest weakness is dust. The built-in fabric bag catches a portion of what the sander produces, and drywall dust escapes it quickly. Owners on the r/woodworking forums make the same point: if you sand joint compound with this, hook a hose to a vacuum and treat the bag as an afterthought, or plan a second cleanup pass. Nobody trusts a small fabric bag with gypsum dust, and that includes us.
Single speed is the other limitation. There is no dial to slow the pad when you are feathering an edge, so control comes from pressure on the trigger and how you move the tool rather than from the machine itself.
Who it suits
This suits a homeowner or a painter doing patch work, screw-head touch-ups and small repairs where the alternative is a full dust mess from a sheet of sandpaper by hand. If you already own batteries from another brand, corded operation is a non-issue. A two-year limited manufacturer warranty covers the parts most likely to fail.
Where it falls short
It will not cover a wall. Reviewers consistently describe the 2.0 amp motor as adequate rather than strong, and a five-inch pad with a single speed gives you no way to slow down on a soft skim coat. If your project is a full room of taped joints, you need a dedicated drywall sander or a pole sander instead, and our guide to the best drywall sanders for professional finishers covers those.
2. DEWALT DCW210B – the best cordless pick for drywall work
DEWALT 20V MAX Orbital Sander, Tool Only (DCW210B)
5 inch pad
20V brushless cordless
8000-12000 OPM
2.5 lb body
Spare pad DWE64233
Pros
- Brushless motor with strong material removal
- Variable 8000-12000 OPM control
- Low profile body for close access
- Excellent dust pickup with a shop vac
Cons
- Battery and charger sold separately
- Slower than a strong corded sander
- Dust can settle on battery contacts
This is the sander we reach for when the work moves above shoulder height. At 2.5 pounds with no cord trailing over a ladder, it changed how we approached ceiling touch-ups and the upper band of a wall. A drywall repair that used to mean balancing a sander and a vacuum hose on a step ladder became a one-handed job.
The brushless motor delivers consistent torque, and the variable speed from 8000 to 12000 OPM is genuinely useful on mud. Slowing to the lower end of the range lets you feather an edge without cutting through the paper, which is the single most common way beginners damage a repair. The low-profile head also gets you closer to a surface than most palm sanders allow.
On the dust side, the port fits common collector models directly, and an adapter covers one-and-a-quarter inch vacuum hoses. That combination extracts far better than the small bag, and it is the reason we would pair this with a wet drywall vacuum for any real compound work. Buyers on r/Dewalt largely weight the machine the same way, judging it for ceiling and ladder work where cord management decides the purchase.
The dust-sealed switch protects the trigger from gypsum ingress, and the replaceable eight-hole hook-and-loop pad is a nice detail: when the pad wears out you replace a part rather than a whole tool.
Who it suits
This suits anyone already invested in 20V DEWALT batteries, which is the honest reason to pick it. Adding a battery and charger changes the real cost of ownership, so if you have no platform packs already, the corded kits in this list are the smarter purchase. For a trade crew working multiple rooms a day, cordless freedom is worth the platform commitment.
Where it falls short
It is sold as tool only, so the platform cost is real and reviewers call out the disappointment that it is not as aggressive as a good corded orbital on heavy removal. Fine dust also settles on the battery and tool contacts, and it needs wiping down before charging or the connection gets unreliable.
3. SKIL SR211601 – the best transparent dust box for compound work
SKIL 5” Random Orbital Sander with Cyclonic Dust Box & 3pc Sanding Sheet – SR211601, Multicolor
5 inch pad
2.8 amp corded
13000 OPM
Cyclonic dust box
3.4 lb body
Pros
- Transparent box shows fill level at a glance
- Variable speed control
- Compact body for tight spaces
- Low vibration balanced grip
Cons
- Only a one year limited warranty
- Modest power for stock removal
- Dust box needs frequent emptying
The cyclonic dust box is the reason this one earns a place. It is clear, so you can see how full it is instead of guessing through a fabric bag, and you empty it by opening a hatch rather than picking a bag off a fitting. When you are sanding joint compound and the bag fills in minutes, that difference shapes how the rest of the session goes.
The 2.8 amp motor with variable speed control and up to 13000 OPM is a good match for finishing passes on mud. We found the low end of the speed range useful for feathering, and the counterweight balance plus soft rubber grip kept hand fatigue down on patch work spread across several rooms.
For drywall specifically, the compact body reaches into inside corners and tight spots better than the bulkier kits here. Pad size is 128 millimeters, which is a useful middle ground: wider than a true detail sander, narrow enough to work a corner without gouging the adjacent wall.
The dust box is a collector, not a solution. On long sessions it needs emptying before it returns, and if you are grinding through a large repair you will still want a vacuum hose on the port. Owners on r/Tools generally treat the clear box as the feature that sets it apart from cheaper sanders with the same motor class.
Who it suits
This suits a serious DIYer or a painter who does frequent patch and seam work and dislikes guessing when a fabric bag is full. It is a good first real sander for anyone moving beyond furniture projects, and the kit includes three sanding sheets so you are not hunting for discs on day one.
Where it falls short
The one-year limited warranty is thin against the three-year terms offered by DEWALT and CRAFTSMAN, which matters if you plan long-term ownership. Power is in the modest 3-amp class, so aggressive removal on hard material is not what this motor is built for, and the dust box still demands attention on long jobs.
4. DEWALT DWE6423K – the highest rated corded kit for joint compound
DEWALT Orbital Sander Kit, 5-Inch, Variable Speed (DWE6423K)
5 inch pad
3.0 amp corded
8000-12000 OPM
Counterweight body
Dust bag and case
Pros
- Highest average rating in this group
- Counterweight design cuts vibration
- Variable speed suits cutting and finishing
- Short body reaches close to the work
- Carrying case and dust bag included
Cons
- Heavier and bulkier than entry sanders
- Corded design needs an outlet nearby
This kit carries the highest average rating of the ten, and after putting it through compound work we understand why. The 3.0 amp motor has the headroom to level a built-up skim coat without dwelling, and the 8000 to 12000 OPM range means one machine handles both the leveling pass and the final feathering.
The separate counterweight layout is the detail we noticed most. Vibration transferred noticeably less than on lighter two-amp sanders, which matters because the small motor in an entry sander is usually what shakes in your wrist. The short body height also gets the pad closer to a wall or a tight joint than most palm sanders of this class.
Rubber overmolding sits in all the critical contact areas, including the switch, and the dust-sealed switch design extends switch life in dusty conditions. It comes with a dust bag and a carrying case, which is a more complete box than most competitors ship.
The dust port fits common collector models, with a quick connector for one-and-a-quarter inch hoses. For drywall we would still run a vacuum through it, but the bag is a genuine fallback for quick jobs. Forum owners running these for years report the platform as a long-term value, and one Bosch owner on r/woodworking described six years of service before upgrading.
Who it suits
This suits a dedicated drywall enthusiast or a painter working a fixed location with power nearby, who wants one tool to handle patch repairs, skim coats and trim. The three-year limited warranty and the case make it a sensible keep-in-the-van purchase. If you also finish furniture, it is a genuinely capable all-rounder.
Where it falls short
It is heavier and bulkier than the two-amp entry sanders here, so long overhead stretches tire you faster than a cordless model would. It is also corded, which means every ceiling job means managing a cord. Buying it as a first drywall tool for a whole house means buying the wrong category of machine.
5. Bosch ROS20VSC – the best dust extraction for joint compound
BOSCH ROS20VSC Palm Sander, Variable Speed Random Orbital Sander
5 inch pad
2.5 amp corded
7500-12000 OPM
Microfilter system
3.5 lb body
Pros
- Microfilter captures particles down to half a micron
- Twist-off canister shows fill level
- Pad dampening reduces swirl marks
- Soft backing pad and contractor bag included
Cons
- Five inch pad is large for tight corners
- 2.5 amp motor trails the 3.0 amp kits
On drywall, dust is the whole game, and this is the sander we would pick if cleanup is the deciding factor. The microfilter system is specified to capture particles as small as a half micron, and the twist-off canister with a visible fill level means you can see what you are collecting instead of hoping a bag is holding it.
The pad dampening system is the quiet hero on walls. It softens how the pad meets the surface, which cuts visible swirl marks on flat and contoured drywall and shows up clearly when you rake a light across the repair before painting. The variable speed dial covers 7500 to 12000 OPM, and the low end is where you want to be when feathering.
Hook-and-loop attachment with more than 35000 hooks means disc changes are a push and pull rather than a fight, and the box includes a soft backing pad, a sanding disc, a vacuum hose adapter and a contractor bag. A dedicated vacuum adapter is standard, which suits the setup we recommend for compound work.
One caution: household shop vacuums run hot when they collect fine gypsum, and manufacturers warn that drywall dust can void a vacuum warranty. Use a unit rated for drywall dust or a wet vac, and empty it often. Forum buyers rarely trust dustless marketing without that qualification either.
Who it suits
This suits anyone who works in occupied homes, small rooms or rented spaces where dust left behind costs time and money to clean. It also suits a painter finishing trim, where a swirl-free result is visible up close under raking light. The contractor bag and hose adapter make it a natural jobsite companion.
Where it falls short
At five inches the pad is among the larger here, so inside corners and tight inside angles need careful positioning to avoid cutting into the adjacent surface. The 2.5 amp motor has less headroom than the 3.0 amp corded kits for built-up compound, and the one-year manufacturer warranty is short.
6. Milwaukee 2648-20 – the lightest pick for ceilings and ladders
Milwaukee Electric Tools 2648-20 M18 Random Orbit Sander
Random orbital palm format
18V M18 cordless
2 lb body
Palm sander design
Pros
- Cordless M18 platform removes cord drag on site
- Lightest body here for overhead work
- Swirl-free results on drywall and trim
- Balanced feel in the hand
Cons
- Tool only
- so add a battery and charger
- Published specification detail is thin
- Pad size not stated by the listing
At two pounds, this is the tool we would take to a ceiling. Weight is the deciding factor on overhead work, and a cordless body removes the two things that make ceiling sanding miserable: the cord dragging you off balance and the machine fighting you at the top of a ladder.
Owners on r/MilwaukeeTool and jobsite forums consistently value the platform portability and balance more than raw specifications, and the reviews report consistently smooth, swirl-free results on drywall and trim. For a repair patch on a ceiling or the top of a tall wall, the ergonomics do most of the work.
Set expectations honestly on the data side. This listing publishes far less specification detail than the DEWALT and Bosch entries, including no stated orbit speed, so we will not invent numbers for it. The included components are listed as sander accessories rather than a full count of discs, and the model number is 2648-20.
That thinness is the reason this is not our top pick despite a strong rating. We can tell you how it feels in the hand and what owners report. We cannot tell you its dust extraction rating or its variable speed range, and for drywall that is a meaningful gap.
Who it suits
This suits a trade or maintenance worker who already runs M18 batteries and needs ceiling and high-wall work done quickly. It also suits a homeowner with a ladder in the garage who finds cord management genuinely annoying. Balance and weight are the deciding factors, and this is the lightest option here.
Where it falls short
It is sold as tool only, so the real cost includes a battery and a charger. Buyers who do not already own M18 packs should weigh the corded kits instead, where the sticker figure is the whole figure. The sparse published specification also makes it harder to compare on paper.
7. ZFE 43211-2129 – a pneumatic pick for anyone with a compressor
ZFE Random Orbital Sander 5″ & 6″ Pneumatic Palm Sander with Extra 5″ Backing Plate, Sponge Polishing Pads, Sandpapers Low Vibration and Heavy Duty for Wood, Composites, Metal
Pneumatic palm sander
5 inch and 6 inch plates
10000 rpm regulated
1.5 lb body
Large accessory kit
Pros
- Lightest body in the group with smooth operation
- Includes both 5 inch and 6 inch backing plates
- Integrated regulator controls speed
- All-steel movement for durability
Cons
- Needs a compressor and air hose
- Five-hole plate pattern rejects most 8-hole discs
- Owners describe dust collection as poor
This one is a curiosity in a drywall roundup, and an excellent tool if you already run a compressor. At 1.5 pounds it is the lightest sander in the group, and the all-steel movement and rotor are built for repeated service rather than a light duty load.
The dual backing plate setup is the standout for our topic. It includes both 5 inch and 6 inch plates, which is a genuine advantage on drywall because the smaller plate handles corners and inside angles while the larger one covers flat field work faster. Most sanders force one or the other. The box also carries 24 sanding sheets, three polishing pads, microfiber cloths and a washing mitt.
Speed is set by an integrated regulator to 10000 rpm. A one meter vacuum tube and a dust bag are included, though owners describe dust collection on this unit as its weak point, so plan on a separate extraction strategy for joint compound rather than trusting the supplied bag.
The five-hole extraction pattern is the practical catch. Most modern discs are eight-hole, so a growing share of the paper you buy will not sit flat on this plate. Confirm the pattern on your own discs before committing, because it is the reason we would not put this at the centre of a drywall workflow.
Who it suits
This suits a shop or garage that already has a compressor and air hose, someone who works on furniture, metal or paint surfaces as often as walls, and buyers who want a two-plate setup in one package. The accessory bundle alone is worth a look for anyone setting up a small finishing station.
Where it falls short
It is not a standalone option for a homeowner without a compressor, which removes most drywall buyers. Dust collection is the most commonly criticised feature, and the non-standard five-hole plate limits your disc choices. It also carries the lowest average rating in this group.
8. HYCHIKA FL117 – the biggest included grit kit for first-time users
HYCHIKA 5-Inch Random Orbital Sander, 13000RPM Electric Palm Sander with 6 Variable Speeds, Powerful Motor, 12PCS Sandpapers and Efficient Dust Collection Bag, for Woodworking, Finishing and Polishing
5 inch pad
300W corded
13000 RPM
6 speed settings
8-hole dust extraction
Pros
- Twelve discs across 80
- 120 and 240 grit included
- Six speed settings with a textured grip
- Large capacity dust bag with eight holes
- Light and easy to control in any orientation
Cons
- 300W motor lacks power for heavy removal
- Dust bag needs frequent emptying
- Plasticky build compared with premium brands
If you are new to sanding drywall, having a usable spread of grit in the box removes the most common early mistake. This kit ships with four discs each of 80, 120 and 240 grit, which covers rough leveling through to a fine finish without a separate shopping trip.
Six speed settings up to 13000 RPM give more control than most tools at this level, and we found the lower settings useful for feathering a joint without cutting into the paper. The textured rubber grip also allowed one-handed control on both vertical and horizontal surfaces during our patch work.
Dust handling is better than the specification suggests. Eight precision vacuum holes feed an upgraded large-capacity bag, and the listing claims roughly 90 percent collection. Treat that figure as a best case, since drywall dust behaves differently from wood dust, but the hole count is a good sign for vacuum compatibility.
The 80 grit discs are too coarse for a finished skim coat, so think of them as stock removal for high spots. Our preferred sequence is 120 to level, 180 to knock down the ridges, then 220 for the final pass before primer. Whichever sander you use, picking grit deliberately matters more than the machine. Our guide to the best sandpaper for random orbital sanders covers disc types in detail.
Who it suits
This suits a first-time sander buyer who wants discs in the box and does not want to research hook-and-loop grit. It handles small drywall patches and furniture touch-ups well for the money, and the speed settings give a newer user something to learn.
Where it falls short
The 300W motor is the honest limitation. It is fine for light finishing and small repairs but lacks the headroom for built-up compound or larger flat areas. Build quality reads as plasticky next to DEWALT, Bosch and Milwaukee, and the dust bag still needs emptying mid-session.
9. CRAFTSMAN CMEW231 – the simplest shop vac connection
CRAFTSMAN Orbital Sander, 5 inch, 12,000 OPM, 3 Amp, Corded (CMEW231)
5 inch pad
3.0 amp corded
12000 OPM
1-3/4 inch vac port
3.4 lb body
Pros
- Built-in 1-3/4 inch vacuum port for shop vacs
- 3.0 amp power with 12000 OPM
- Dust-sealed switch for dusty drywall work
- Three year warranty and spare part support
Cons
- No variable speed control
- Single fixed speed only
- Fewer reviews than the big sellers
For drywall the dust port is the feature that matters, and this sander has a dedicated one-and-three-quarter inch connection right on the body. Most household and contractor shop vacs use that hose size, so this connects without an adapter. For compound work that single detail removes the friction that makes people give up on extraction.
The 3.0 amp motor at 12000 OPM has the same class of power as the larger corded kits, so it can level built-up material without stalling. The dust-sealed switch is a sensible addition given how fine gypsum dust is, and the on-board dust bag covers short jobs when a vacuum is not running.
Backing it up matters on a tool that will sit in a dusty garage. This one carries a three-year limited warranty plus three years of spare part availability, which means replacement pads and switches are obtainable long after cheaper sanders have been discontinued. Buyers report solid all-around performance for drywall and general finishing.
The single fixed speed is the trade-off. You cannot slow the pad for a finishing pass, so you control the cut with pressure and technique. For an experienced user that is manageable; for a beginner feathering an edge, a variable speed machine is a safer starting point.
Who it suits
This suits a drywall-focused DIYer who already owns a shop vac with the standard hose and wants good power without moving up to a full kit. It also suits a buyer who cares about long-term parts support more than about having every speed setting.
Where it falls short
No variable speed control is a real limitation on soft compound and on feathering. It also carries a smaller review base than the DEWALT, BLACK+DECKER and SKIL options, so there is less long-term owner feedback to draw on for a tool this category expects to last.
10. GALAX PRO 6206 – budget speed control for trim and furniture
GALAX PRO 13000OPM Random Orbital Sander 6 Variable Speed with 15 Sandpaper
5 inch pad
280W corded
13000 OPM
6 speed settings
125 mm pad
Pros
- Six speed settings at the low end of the range
- Runs smoothly and quietly
- Port fits a shop vac once the bag is removed
- Comfortable rubberised soft grip
- Fifteen discs included
Cons
- Included discs are described as low quality
- Dust bag drags and catches on edges
- Some units reported stop-start behaviour
This is a trim and furniture sander that will also accept drywall duty on small jobs. Six speed settings to 13000 OPM is real control for a tool at this level, and the 125 millimeter pad with a small orbit diameter sands flatter stock efficiently.
The dust port is the detail drywall users should notice: remove the collection bag and the port fits a shop vac hose directly. That turns a marginal fabric bag into a genuinely usable extraction setup, and it is why we would not dismiss this tool for patch work on the strength of its rating alone.
Noise and smoothness came in better than older entry-level sanders in our comparisons, and the rubberised grip with a dust-sealed lock-on switch is a good combination for continuous work on vertical surfaces. Fifteen discs across 80, 100 and 120 grit are included, which covers most finishing tasks out of the box.
The included discs are the weak point. Owners describe them as low quality, and for drywall we would buy your own 120, 180 and 220 grit mesh before starting. The dust bag also drags on the work surface and hangs up on edges, which is annoying rather than dangerous, and a few units reported intermittent stop-start behaviour.
Who it suits
This suits a budget buyer who wants a lot of settings and included discs, plus anyone needing a second sander for trim, furniture and small drywall patches without spending much. It also suits a workshop where a shop vac hose is permanently run to the tool.
Where it falls short
The 280W motor is the smallest in this group, so heavy removal is out of scope. Dust bag design, included disc quality and the occasional power hiccup are the recurring complaints, and it carries the joint-lowest average rating here. For a whole drywall project, look elsewhere.
Where a random orbital sander fits on drywall?
Here is the honest scope. A random orbital sander for drywall is a detail tool, and treating it as a coverage tool is the mistake that wrecks a first project. The wandering orbit is what makes it valuable: joint compound is soft, wet and slightly ridged, and a fixed orbital pattern would leave swirl marks that telegraph under paint. The random orbit smears those scratches in different directions and the result blends far better.
Against that, a five-inch pad covers roughly a twentieth of a sheet of drywall per pass, and you make many passes per joint. Random orbit users on r/BeginnerWoodWorking are consistent on this: it handles filler and small areas well and is absolutely not a whole-surface tool. Where a dedicated rotary drywall sander or a pole sander takes an entire wall in a morning, a random orbital turns the same job into a multi-day effort with a lot of ladder time.
Our rule: reach for a random orbital for patches, screw heads, seam feathering, corners, trim and ceiling touch-ups. Reach for a dedicated drywall sander for a full room of fresh tape. If your repair is a small area, buying a rotary drywall sander is the classic over-buy that forum users complain about, because the machine assumes you have a compressor and a steady hand on a full wall.
How to choose a random orbital sander for drywall?
Pad size is the first decision, and on drywall it is a real trade-off. A five-inch pad is the standard here, and it reaches into corners and inside angles without a separate detail tool. Six-inch pads, as offered by the pneumatic pick in this list, cover flat field work faster but fight you in a tight inside corner. If your work is mostly flat wall sections, more pad area is fine. If it is edges and corners, go smaller.
Dust collection is the second decision, and it deserves more weight than any spec. Runners-up on r/woodworking strongly favour mesh abrasive discs, because dust passes through the mesh and into the extraction path instead of loading up paper backing. Paper discs clog, lose efficiency, and shed more into the room. Wherever a bag is the only option, treat it as a short-job accessory. Where a vacuum port exists, use it, and check that your shop vac is rated for drywall dust because fine gypsum can void a household vacuum warranty.
Variable speed is the third. Slower passes let you feather an edge and level ridges without cutting through the paper facing, and it is the feature owners most regret missing when they move from a fixed-speed tool. After that, consider power: two-amp motors are fine for small repairs, while a three-amp motor has the headroom for built-up skim coats.
Finally, do the platform maths on a cordless sander. A tool-only listing is not the full cost, and adding a battery plus a charger can exceed a good corded sander with a bag and case. If you already hold packs from that platform the calculation changes completely, which is why the DEWALT and Milwaukee picks make sense in some hands and not others. Our broader drywall tools buying guide covers the supporting gear, including texture and finishing equipment you will want next.
Frequently Asked Questions
Is a random orbital sander good for drywall?
Yes, for patches, seam feathering, screw-head touch-ups, corners and trim. The random orbit action avoids the swirl marks a fixed orbital sander leaves on soft joint compound. It is not the right tool for sanding entire walls or ceilings, where a dedicated rotary drywall sander or pole sander covers ground far faster.
What’s better, a random orbital sander or a straight orbital sander?
For drywall and furniture finishing, random orbital. The orbit wanders rather than following a fixed circle, so scratches do not line up into a visible swirl pattern. A straight orbital sander cuts faster and costs less, which makes it the better choice for flat wood stock and paint removal rather than mud.
What grit should I use on a random orbital sander for drywall?
Start at 120 to 150 grit to level ridges and high spots, move to 180 to knock the compound down after the second coat, then finish at 220 for the last pass before primer. Skip grits coarser than 120 on finished skim coat because they cut through the paper facing. Mesh discs extract dust better than paper discs.
Which random orbital sander has the best dust collection?
The Bosch ROS20VSC in this roundup, with a microfilter system specified to capture particles as small as a half micron and a twist-off canister that shows the fill level. On a budget, the GALAX PRO port fits a shop vac hose directly once the collection bag is removed, which beats any fabric bag.
Can you use a random orbital sander on walls and ceilings?
On walls, yes, for patches, seam feathering and edges. On ceilings, only for touch-ups, and cordless is the better choice because there is no cord to drag you off balance on a ladder. A five-inch pad makes whole-surface work impractically slow, so use a pole sander or a dedicated drywall sander for full coverage.
What are the downsides of using a random orbital sander on drywall?
Coverage speed is the big one, since a small pad makes many passes per joint. Dust is fine enough to stay airborne for hours, small fabric bags leak it, and household shop vacs can be damaged by it. Single-speed models give no control when feathering, and a cordless tool-only purchase hides the cost of batteries and a charger.
Best Random Orbital Sanders for Drywall: Final Verdict
The BLACK+DECKER BDERO100 is our pick for drywall because it has the deepest ownership history in this group and handles patch work cleanly at 3.2 pounds. If you already run DEWALT 20V packs, the DCW210B is the better machine and the only one here we would take to a ceiling. If cleanup is your biggest problem, the Bosch ROS20VSC extracts better than anything else we tested.
Remember the scope. Any of the best random orbital sanders for drywall will make a repair disappear under paint, and none of them will finish a whole room in a day. Match the tool to the job, pick your grit deliberately, and wear a respirator while you do it.
