12 Best Amazon Prime Big Deal Days Eufy Deals (October 2026 Sale)

If you want one eufy purchase to carry the most weight during Amazon’s October sale, the eufy E25 Robot Vacuum is the pick to watch: 20,000 Pa of suction, a HydroJet roller that rinses itself twice per second and a station that empties and dries for roughly 75 days without you touching it. Two alternatives serve different homes. The eufy Omni C20 does the same vacuum-and-mop cycle with a station that fits in tighter rooms, and the eufy 11S MAX is the pick if you want something thin enough to slide under low furniture and nothing else. Twelve eufy picks are worth watching during Prime Big Deal Days in 2026, and most of the offers run October 6-7, 2026.

The list leans on what the specs and owner reviews actually say rather than on discount badges, because those badges change hourly and the price history does not. Every product below has a rating, a review count and a spec sheet behind it.

Best Amazon Prime Big Deal Days Eufy Deals Compared

Twelve picks across robot vacuums, indoor and outdoor cameras, a video doorbell and three smart locks. The three columns below are the same for every row, so you can scan down the list quickly.

How We Chose

We compared the specifications that decide a purchase in this category: suction power, body height, battery and runtime figures, sensor type, storage options, Wi-Fi band and installation method. We also read the owner reviews attached to each listing, since recurring complaints tell you more than a spec sheet does. Specs, ratings and review counts were checked on Amazon in (October 2026).

1. eufy E25 Robot Vacuum: Best Overall

The E25 is the vacuum to watch if you want one machine to cover vacuuming, mopping and post-mop cleanup. The HydroJet roller runs water through the pad twice per second, and the All-in-One Station empties into a 3L bag, washes the roller and dries it at 50C.

That is roughly 75 days of hands-free runs before you think about the bag. Suction is the headline number at 20,000 Pa, and the specs say it is aimed at embedded carpet dirt and grout lines rather than surface crumbs.

For a house with two shedding pets, the DuoRoller brush design matters more here than the headline figure. Five floor plans are stored through laser navigation, a single clean runs up to 125 minutes before it returns, and the CornerRover arm extends into baseboard edges and furniture legs, which is where most robot vacuums leave a visible stripe.

Owners report the trade-off clearly: the cleaning solution is proprietary, so you cannot substitute your own, and some reviews mention a faint waxy film left on hard floors. The roller also re-washes every time the machine changes floor level, and that step cannot be switched off.

Compared with the eufy Omni C20, the E25 buys roughly triple the suction, a longer runtime and hot-air drying, at the cost of a bulkier station. Compared with the eufy C28, you give up the camera-free LiDAR and lose the white cabinet-friendly finish. If your floors are mostly carpet or you have pets, the E25 is the one to watch. If you want a slim machine that fits in a small utility closet, look at the C20.

2. eufy Omni C20: Best Value

The C20 is the one to watch if the station will not fit where you keep it. At 11.38 inches long and 19.9 pounds, it takes up noticeably less counter space than the E25’s station, and the vacuum body itself is 3.35 inches tall, so it slides under sofas with as little as 3.54 inches of clearance.

It vacuums and mops in the same pass, pressing the pad down with 6N of force at 180 RPM, and the mop lifts on its own when carpet is detected. A 3.1L bag means about 60 days between empties.

Three things set it apart from the E25 and the 11S MAX. No-go zones plus room or zone cleaning are all in the app, three floor maps fit in the iPath laser navigation, and runtime of 132 minutes is the longest of the vacuums here, with the machine recharging and resuming on its own.

The two limits worth knowing before you buy are practical ones. It connects to 2.4 GHz Wi-Fi only, so a dual-band router needs its 2.4 GHz network on and separate. And boundary strips are not included, which matters if you have cables or a rug edge the machine should not cross.

Owners also mention that mop drying uses room-temperature air rather than heated drying, so pads stay slightly damp longer than they do in the E25 or C28 stations. Put it next to the E25 and the trade is straightforward: you lose suction and heated drying, and you gain a smaller footprint and a lower price tier. Set beside the eufy 11S MAX, you gain mapping, mopping and an emptying station at the cost of a higher price band.

3. eufy 11S MAX: Most Versatile

This is the simplest machine on the list and that is the point. At 2.85 inches, the 11S MAX goes under coffee tables, low sofas and platform beds where nothing else here fits. It runs at 55 dB, quiet enough that owners report using it during calls and while asleep.

Operation is a remote control and the buttons on the unit. There is no app, no Wi-Fi, no mapping and no room zoning. BoostIQ adjusts suction as it moves across surfaces, and it returns to its charging base when the run ends.

The 600 ml dustbin is the piece owners complain about most, because nothing auto-empties it and emptying it is a messy job. Reviewers also report the machine occasionally catching a cord or a thin furniture leg with no alert sound, and some note inconsistent battery longevity over the years.

Good to know: this is a vacuum only. There is no mop pad and no water tank, so it is not a pick for anyone who wants hard floors mopped.

The comparison is simple. If a 3.35-inch machine clears your furniture, the eufy Omni C20 does more for the money. If it does not, the 11S MAX is the only one in the list that still fits, and it has the highest review count of the twelve. For an upstairs flat with low furniture and no interest in an app, it is the sensible pick.

4. eufy C28 Robot Vacuum: Best for Camera-Free Navigation

The C28 makes the same privacy argument that camera-free mapping is built for: it navigates with LiDAR, not with a lens pointed around your living room. The specs say it steers around obstacles of 3 cm and larger, which is enough to clear furniture, toys and pet bowls.

Suction is 15,000 Pa, between the E25 and the Omni C20, and battery life of 140 minutes is the longest runtime here. The 28 cm HydroJet roller spins at 270 RPM through 24 water ports, with a scraper pushing dirt into a separate tank so the roller stays cleaner while it mops.

DuoRoller brushes are rated for hair up to 11.8 inches long without wrapping, which is the number that matters in a home with a long-haired dog. The station handles about 75 days and dries the mop with hot air at 50C, the same process as the E25.

Two boundaries are worth noting. It is rated for hard floors, wood and short wool carpet, so long-pile carpet needs no-go zones set in the app. And like the E25, the mop re-washes whenever it moves between floor levels, and the cleaning solution is a single branded formula.

What the C28 adds to the E25 is camera-free navigation, a longer runtime and a white station that fits into cabinetry, and what it gives up is some suction. Set it beside the eufy Omni C20 and it is the more powerful machine with the bulkier station. Reviewers pair it with the same praise for hot-air drying and the same frustration about the mop wash.

5. eufy SoloCam S340: Best for Solar Outdoor Coverage

The S340 is the pick for a porch, driveway or backyard where running a cable is not an option. A removable solar panel sits above the body and keeps a 10,000 mAh battery topped up, and installation takes about seven minutes with two screws.

Two lenses capture 3K video with 8x hybrid zoom across a 360-degree pan and tilt, so a vertical mount still covers the approach to the door. Storage is 8 GB built in, and there is no monthly subscription to pay for features the listing says are included.

Owners consistently praise the combination of solar power, clarity and no recurring fee at this tier. What they also mention is the night vision range of roughly 6 meters, which is shorter than most competing outdoor cameras and means the far end of a long driveway will be dark.

The 8 GB of storage is fixed rather than expandable to a card, and the camera connects to 2.4 GHz Wi-Fi only. Good to know: alerts are motion-based, so a camera covering a sidewalk will record people passing rather than only the ones you care about.

If you need to see further at night outdoors, the eufy Video Doorbell E340 reaches 16 feet with color night vision and covers the front door as well. For a driveway or a side yard where wiring is not an option at all, the S340 is the one that works without a hub.

6. eufy Indoor Cam E220: Best for Pet Watching

Owners call the E220 the budget indoor pan-and-tilt camera that keeps working without a plan. It records to a microSD card up to 128 GB with no subscription, and on-device AI records events when a person or pet appears rather than storing everything.

Two-way audio lets you talk to a dog that is pacing, or to a family member at home. Mounting is a plug-in unit in a corner or on a shelf, and the body is 10.56 ounces, so it moves easily to a different room.

Where it falls short is range. Reviewers report that human and pet detection is inconsistent at distance and on stairs, and there are no preset viewing positions, so the head has to be turned by hand to point at the crate or the sofa. Only two activity zones can be configured, and app playback is described as slow.

Good to know: the listing advertises support up to 256 GB while the camera accepts 128 GB. Buy the card to the camera’s limit, not the listing’s.

The eufy Indoor Cam E30 records in 4K, detects crying and audio events and supports HomeKit, which is why it suits a nursery. What the E220 gives up against the eufy Indoor Cam S350 is the telephoto lens, presets and 32-foot night vision. For a first camera in a living room or a dog’s crate corner, the E220 does the job at the lowest tier here.

7. eufy Video Doorbell E340: Best for Package Deliveries

The E340 is built around one specific problem: seeing what happens at your front door from head height down to the mat. One camera watches for visitors, the second points down at packages, and both record to 8 GB of built-in storage with no monthly fee.

It installs either on battery or wired to existing doorbell wiring, and the rechargeable battery releases with a quick pull instead of a screw. Owners single out motion filtering as better than most competing doorbells, with passing cars filtered out where others trigger constantly.

The trade-off owners report most often is battery life, which in practice lands closer to two months than the longer stated figure. App notifications and live view load slowly enough that some people miss real-time events. In direct sun the unit can overheat and shut down, and the downward camera shows slight flicker at night.

Skip this one if your door faces west with no porch shade. Good to know: it can pair with an existing mechanical chime or a MiniBase Chime as well as HomeBase 2 or 3.

The eufy Smart Lock E330 does more at the same door, adding fingerprint entry to the camera, but its reader misses more often. If you want video at the door and no lock, the E340 is the more reliable of the two. The eufy SoloCam S340 covers the wider yard rather than the doorstep itself.

8. eufy Indoor Cam S350: Best for Night Vision

The S350 is the only camera in this list with both a wide 4K lens and a separate 2K telephoto, and the split-screen view shows them at the same time. That is what lets one unit cover a whole room and still resolve detail at the far end.

Night vision reaches 32 feet using dual infrared lights, which is why it is the pick for a dark basement, garage conversion or hallway. Presets remember not just the angle but which lens to use, so a crib, a pet bed or a front door each get one tap.

Owners say one S350 replaces two cheaper indoor cameras. They also report occasional SD card formatting prompts that they attribute to firmware, false alerts from light reflections and fixed objects such as wall art, and a head that sits slightly top-heavy on the base.

Two setup details. It works on both 2.4 GHz and 5 GHz, which almost nothing else in the eufy line does. And the memory card slot is only reachable when the lens is tilted up, so leave room for that during first-time setup. HomeKit is not supported and HomeBase 2 will not pair with it.

Against the eufy Indoor Cam E30, the S350 adds the telephoto lens, presets and 32-foot night vision but loses HomeKit. Against the eufy Indoor Cam E220, it costs more and does considerably more. If the room is dark and you need to identify something at range, the S350 is the one to watch.

9. eufy Indoor Cam E30: Best for Baby Monitors

The E30 is the pick for a nursery or a room where someone cannot speak up yet. Its on-device AI separates human, pet, general audio and crying events, so a cry alert is distinct from a notification about movement. Pre-motion footage is captured so an event is not missed at the start.

Video is 4K UHD with smooth 360-degree pan and tilt, and Quick Focus Tap moves the camera wherever you tap on screen. The built-in spotlight switches to color night vision when enabled, which is more useful than infrared when you want to see fabric colors at 2 a.m.

It pairs with HomeKit, Alexa and Google Assistant, and local microSD storage keeps everything working without a plan. Setup typically takes about five minutes.

Owners flag the storage requirement: 4K recording needs a high-endurance card, and the card is sold separately. Pre-motion recording only runs if you enable it in settings, and motion sensitivity will react to sudden changes in light or shadows, which happens often with curtains. Some owners report missed detections and slow app playback.

Compared with the eufy Indoor Cam S350, the E30 is the cheaper and simpler unit with HomeKit support, while the S350 adds the telephoto lens and reaches twice as far at night. Compared with the eufy Indoor Cam E220, the E30 doubles the resolution and adds cry detection. For monitoring a sleeping child, a convalescing relative or a new puppy, it covers the same room more precisely.

10. eufy Smart Lock C220: Best for a First Lock Upgrade

The C220 is the straightforward smart lock to start with. It offers six ways in: fingerprint, keypad, app, physical key, Apple Watch and voice, and the fingerprint module learns from each use rather than working from a fixed set.

Built-in Wi-Fi means remote control works without buying a separate bridge, which is where most first-time lock buyers get caught. It installs in about 15 minutes without drilling on bores under 54 mm, and the body is aluminium with BHMA Grade 3 certification over 100,000 cycles.

Eight AA batteries are rated at about eight months, though owners with heavy traffic report shorter. The most common complaint is a fingerprint reader that occasionally fails on the first attempt and needs a second press, which matters most for the person who was relying on it most.

One feature that will disappoint anyone building a full system: the lock can raise an alarm on unusual opening attempts, but it cannot link per-door sensors to a HomeBase setup. Good to know: the battery compartment is not weather-sealed, so an exposed door without a doorstop needs cover.

Against the eufy Smart Lock E330, the C220 gives up the camera but is more reliable at fingerprint reads and sits at a lower price point. Against the eufy Smart Lock C33, it swaps the lever handle for a standard deadbolt look. For a front door that still has its existing deadbolt, the C220 is the least disruptive install in this list.

11. eufy Smart Lock E330: Best for Lock and Doorbell in One

The E330 merges a 2K HD doorbell camera with fingerprint entry into a single unit, so you get one device at the door instead of a doorbell and a lock. The f/1.6 lens sends visitor notifications with thumbnail previews to the eufy Security app.

The 10,000 mAh rechargeable battery is the largest here and holds up for everyday use, and the lock is BHMA Grade 3 certified and IP65 rated for weather. Installation is roughly 15 minutes without drilling on most standard US deadbolts.

This is the pick to think hardest about before buying. Reviewers report the fingerprint reader failing on roughly three out of five attempts for some users, which on a front door is a daily irritation. The camera also misses fast-moving events and sends several notifications for one event.

Recharging takes about four hours, and a house with a busy front door may want the spare battery. Good to know: eufy Chime, Chime 2 and HomeBase 3 are sold separately if you want local storage options beyond the 8 GB built in.

Compared with the eufy Video Doorbell E340, the E330 adds keyless entry and a much larger battery but is less reliable at fingerprint reads and slower to recharge. Compared with the eufy Smart Lock C220, it costs more and adds a camera the C220 does not have. Buy it if you are replacing both a doorbell and a lock and can live with the reader’s misses.

12. eufy Smart Lock C33: Best for Lever-Handle Doors

The C33 is the pick when you want a lock that still looks and feels like a door handle. The fingerprint reader sits inside the lever grip, so you rest a finger where the handle already is, and the back-lit keypad takes a passcode with an anti-peeping option for entry in the dark.

Built-in Wi-Fi handles remote access, scheduling and event history without a bridge, and the lock fits inward- or outward-swinging doors in about 15 minutes without drilling. Owners who bought one for a front door often report buying a second for a garage or side entry.

The weakness is the same one owners of the eufy Smart Lock E330 raise, in a different form: fingerprint recognition succeeds about 80 percent of the time, which is frustrating for daily use. The auto-lock setting also cannot be turned off without losing the scheduled auto-lock, and the app has trouble adding new users or holding a connection to the lock.

Two practical notes. Because Wi-Fi is always powered, eight AA batteries drain faster than on a non-connected lock. And the supplied physical key is thicker than standard, so the rest of the house cannot be rekeyed to it.

Against the eufy Smart Lock C220, the C33 suits a door that already has a lever rather than a deadbolt and includes an 18-month warranty. Against the eufy Smart Lock E330, it gives up the camera entirely. If the handle shape is what you want, nothing else here replaces it.

How to Choose Eufy Smart Home Devices During Prime Big Deal Days

Eufy covers a lot of ground, so the useful comparison is rarely brand to brand. It is vacuum to camera, doorbell to lock, and floor plan to floor plan. These six checks decide most purchases.

Coverage and monitoring needs

Match the device to the area that actually needs watching. A robot vacuum covers floors, an indoor camera covers one room, a solar camera covers a yard and a doorbell covers a doorstep. For cameras, check the night vision range against your space: the eufy SoloCam S340 reaches about 6 meters, the eufy Video Doorbell E340 reaches 16 feet with color night vision and the eufy Indoor Cam S350 reaches 32 feet. A range shorter than your room leaves the far corner dark.

Power and installation requirements

Decide what you are willing to run. The eufy Indoor Cam E220, eufy Indoor Cam E30 and eufy Indoor Cam S350 plug in and stay put. The eufy SoloCam S340 runs on solar and battery with no wiring at all. The eufy Video Doorbell E340 works on battery or on existing doorbell wiring. On the vacuum side, all four machines here dock at a base or station, and the station footprint matters more than people expect in a small utility room.

Detection and smart home features

Detection is where the four indoor cameras differ most. The eufy Indoor Cam E30 separates humans, pets, general audio and crying on-device. The eufy Indoor Cam E220 runs human and pet detection but misses people at distance and on stairs. The eufy Indoor Cam S350 adds cry and audio events plus presets that remember the lens to use. Check whether your router keeps 2.4 GHz and 5 GHz on separate networks: most eufy cameras here are 2.4 GHz only, and the S350 is the exception.

Storage, privacy and subscription costs

Everything in this list works without a monthly plan. The eufy Indoor Cam S350 and eufy Indoor Cam E30 record to a microSD card sold separately, the eufy SoloCam S340 and eufy Video Doorbell E340 carry 8 GB built in, and the eufy Smart Lock E330 pairs with HomeBase 3 if you want more. On privacy, the eufy C28 Robot Vacuum navigates with LiDAR and no cameras at all, which is the one model here that does not point a lens inside your home.

Ecosystem compatibility and household use

Households usually add devices over years, so check what the first purchase locks you into. HomeKit support is present on the eufy Indoor Cam E220 and eufy Indoor Cam E30, absent on the eufy Indoor Cam S350, and drops that camera to 1080P when HomeKit is used. HomeBase 2 will not pair with the S350. For locks, the eufy Smart Lock C220 works with Apple Watch unlock while the eufy Smart Lock C33 does not accept NFC cards, and neither integrates per-door alarms with HomeBase sensors.

How to shop eufy deals during Prime Big Deal Days

On each listing check the model number before you commit, because eufy reuses similar names across regions and model years. Confirm whether the package is a single unit or a kit, and whether a base station, chime or microSD card is included, since several of these list the card separately. Check whether the listing is new or renewed, and who sells and ships it. Most eufy offers need a Prime membership, and prices shift through the event.

• Match the device to one zone of the home before comparing anything else
• Check night vision range against the room, not just the headline resolution
• Confirm 2.4 GHz or 5 GHz support against your router setup
• Budget for the microSD card on the E30 and S350, which do not include one
• Verify the model number and whether the kit includes a base or chime
• Most offers need a Prime membership and can change during the event

Final Verdict: Best Amazon Prime Big Deal Days Eufy Deals

Buy the eufy E25 Robot Vacuum if you have pets, carpet or a mixed floor plan and want the machine to mop and clean its own mop for months at a time. It is the strongest all-round pick here, with 20,000 Pa suction and a station that handles about 75 days.
