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

The eufy 11S MAX leads this lineup of eufy deals because it cleans hard floors and medium carpet quietly, slips under low furniture at 2.85 inches, and needs no app, account or Wi-Fi pairing to work. For anyone who wants a robot that also mops and empties its own bin, the eufy E25 is the pick; the eufy Omni C20 covers the same ground for less money. Amazon’s Prime Big Deal Days sale runs October 6-7, 2026, and most offers need a Prime membership.

That simplicity is the reason the 11S MAX still carries more owner reviews than anything else in this lineup. It also is the reason a shopper should read the fine print on the pricier picks. Every product below stores video locally, every one of them joins a phone app, and the biggest differences between them are suction, resolution and how much hands-on upkeep the base station asks of you.

Our Top 3 Picks for Best Amazon Prime Big Deal Days Eufy Deals

Best Amazon Prime Big Deal Days Eufy Deals Compared (2026)

How We Chose

We compared the specifications that decide daily use: suction, runtime, base station functions, camera resolution, storage options, power source and installation requirements. Ratings and owner review themes on Amazon shaped the order, and the spec data was checked in October 2026. No hands-on testing is claimed here.

1. eufy 11S MAX: Editor’s Choice for Quiet Everyday Cleaning

The best overall pick for anyone who just wants the floors done. At 2.85 inches tall, this is one of the slimmer robots on the market, and that height is the whole reason it earns its place. Coffee tables, bed frames and low sideboards that stop every other machine are simply not in its way.

Buy the eufy 11S MAX if your home is mostly hard floor with medium-pile carpet and you would rather not set up an account. Operation is a handheld remote, and the box holds the robot, a cleaning tool, side brush, charging adapter and instructions. That simplicity is unusual at this point in the lineup.

• Runs up to 100 minutes on a charge and returns to its base on its own
• BoostIQ raises and lowers suction as it moves between surfaces
• Infrared sensors catch drops and obstacles, and the glass top resists scratches
• 55 dB operation keeps it workable in a room where someone is sleeping

Owners report the trade-off clearly: there is no mapping, so the cleaning pattern is random and you cannot tell it to clean one room. Some also say the battery and durability fall short of what they expected, and the 600 ml bin means a trip to the kitchen every run or two. If that bothers you, the eufy Omni C20 gives you a base station that empties the bin and a map of your home instead.

2. eufy E25: Premium Pick for Pet Hair and Hands-Off Cleaning

Where the 11S MAX vacuums, the eufy E25 vacuums, mops, empties itself and refills its own water tank. The 20000 Pa suction figure is the highest in this group by a wide margin, and the HydroJet roller rinses itself twice per second so you are not dragging a dirty pad across a second room.

For a two-dog household with hard floors and a lot of hair, this is the machine the rest of the list is measured against. The All-in-One Station empties into a 3L bag, washes the mops, dries them at 50C and refills clean water, which means weeks pass between the kinds of chores most owners actually resent.

The catch is footprint and lock-in. The station measures 18.18 inches wide and 17.17 inches deep, so it wants a real corner of a room rather than a gap under a cabinet. The station also uses one specific eufy cleaning solution formula, and owners mention a faint waxy residue left on some floors. It connects on 2.4GHz only, so a dual-band router is worth checking before you commit.

Compared with the eufy C28, the E25 trades the C28’s LiDAR obstacle detection for a more aggressive mop system. Compared with the eufy Omni C20, it buys roughly triple the suction and far more floor maps for a steeper jump in money. Reviewers also report good experiences with eufy support and replacement units when early machines had docking or mop-washing faults.

3. eufy Omni C20: Best Value Robot With a Self-Emptying Station

The pick most people should actually buy. The eufy Omni C20 does the two things that matter in a robot vacuum for most homes: it keeps a map, and it empties its own bin. Everything else on this list either costs substantially more or gives up one of those.

Its 3.35 inch body is even slimmer than the 11S MAX, and it needs only 3.54 inches of clearance, which opens up low furniture that stops larger robots. It vacuums and mops in the same pass at 6N of mop pressure and 180 RPM, and the station collects everything in a 3.1L bag so you are not emptying it after every run.

• Laser navigation with up to 3 floor maps and automatic switching between levels
• Mop lifts 10.8mm when carpet is detected, so hard floors stay dry
• Pro-Detangle comb reduces how fast long pet hair wraps around the roller
• Works with the eufy app, Alexa, Google Assistant and Siri

Skip it if deep carpet cleaning is the goal. 7000 Pa is a real step down from the 20000 Pa in the E25, and the two limitations owners raise most are 2.4GHz-only Wi-Fi and the absence of magnetic boundary strips, which some people use to keep the robot out of a corner. The 132 minute runtime and auto-recharge with resume more than make up for the rest.

Zone cleaning and no-go areas exist in the app, but they take a few mapping runs before they behave, which is the usual trade with laser-navigation robots. Against the eufy X10 Pro Omni, the C20 gets you a slimmer body and less setup fuss but a smaller tank and no heated drying.

4. eufy C28: Best for Homes With Shedding Pets

The eufy C28 is built around one specific problem: long hair wrapped around brush bars. Its DuoSpire dual anti-tangle brushes are rated to handle strands up to 30cm, or 11.8 inches, without the wrapping that turns a vacuum into a pair of scissors you have to free with scissors.

For a home with a long-haired cat or a shedding dog, that is a genuine weekly saving on the job owners complain about most. Suction sits at 15000 Pa with automatic carpet boost, and the 28cm HydroJet roller spins nine times per second with 24 water ports and a built-in scraper to keep the pad rinsing itself while it works.

Good to know: the navigation here is LiDAR without cameras, so it detects obstacles down to 3cm and does not film your living room as it maps it. That is a different privacy trade from the eufy X10 Pro Omni, which uses camera-based object recognition. Several reviews mention the C28 struggling with cables and toys lying flat, which LiDAR can miss.

The station is the drawback. At 18.14 inches tall and 15.47 inches long it needs somewhere to live permanently, and the 10.8mm mop lift is not much on deep pile. If your home is small or your pet hair is short, the eufy Omni C20 does the same core job with a smaller station.

5. eufy X10 Pro Omni: Best for Carpet-Heavy Homes

The eufy X10 Pro Omni is the carpet answer in this group. Its mops lift 12mm off the floor when the robot senses carpet, which is more travel than the 10.8mm offered by the C28 and the Omni C20, and the 3L clean water tank covers up to 2,000 sq ft before a refill.

Its mapping is the most adjustable here. AI.Map 3.0 gives you no-go zones and virtual boundaries, and AI.See Smart Cleaning is trained to recognise more than 100 object types, from cables to toys, using the camera on the unit. For a house where the robot shares floor space with cables, that recognition is worth more than raw suction.

The 4.2 rating reflects a specific set of complaints rather than a broken product. Owners report inconsistent mopping and dock-finding, no paper instructions in the box, and slow support after a firmware update caused problems. At 26.4 lb it is also the heaviest machine here, which matters if the base is not on the ground floor.

At 8000 Pa it sits between the budget 11S MAX and the C20 on raw power, so the case for it is the mapping and the carpet handling, not the suction. A Pro-Detangling roller brush keeps pet hair off the bar, and the 2.5L bag typically lasts about two months.

Good to know: the eufy cleaning solution is not included, and this unit joins a 2.4GHz network only. If you want camera-free mapping instead, the eufy C28 is the alternative.

6. eufy Indoor Cam E220: Budget Pick for Watching Pets Indoors

The cheapest way into eufy home security, and it works indoors without a subscription. The eufy Indoor Cam E220 records 2K video, pans a full 360 degrees, and runs the human and pet detection on the device itself rather than in the cloud. A dog on the sofa is not the same alert as a person at the door.

It is the pick for a pet owner who wants to check on an animal during the workday, or a parent watching a nursery. Two-way audio is built in, night vision holds up in a dim room, and the microSD slot means no monthly fee if you do not want cloud storage.

Owners point to one consistent weakness: human detection gets unreliable at longer distances and on stairs, where the camera sees a shape rather than a face. The app is also reported as slow when pulling up recordings, and the pan position resets to centre after a reboot, so the camera needs a spot chosen carefully rather than one you adjust on the fly.

It runs on 2.4GHz only and drops to 1080P when you view it through HomeKit. For a fixed outdoor post with no wiring and no interest in plugging anything in, the eufy SoloCam S340 is the better hardware.

7. eufy SoloCam S340: Best for Solar-Powered Outdoor Coverage

Running a cable to the back of the house is rarely an option, which is where the eufy SoloCam S340 earns its place. The removable solar panel is a one-time install rather than something you reangle every season, and the 10000mAh battery carries it through stretches where the sun does not.

Image quality is the strongest of the two eufy cameras here. 3K dual-camera capture with 8x hybrid zoom and colour night vision covers a 40 ft radius, and a 360 degree pan means one unit can watch a driveway corner or a side gate without a second camera. Storage is 8GB built in, with no monthly fee.

Good to know: this model has no microSD slot, so 8GB of built-in storage is what you get. The most common complaint is reach, since it joins 2.4GHz networks and struggles through walls and windows to a router in another room. Owners also warn that a shaded or north-facing mount drains the battery much faster than the panel ratings suggest.

Its 4.2 average is the second-lowest in this list, and one-star reviews make up a larger share than on the indoor cameras. Against the eufy Indoor Cam E220, the S340 wins outdoors and loses indoors, where plug-in power is easier.

8. eufy Video Doorbell E340: Best for Watching Delivered Parcels

Two cameras are the point of the eufy Video Doorbell E340. The upper lens frames a visitor head to toe, and the lower one points down at the mat, so a delivery sitting below the main field of view still triggers a package alert instead of being invisible.

It runs on the rechargeable battery, so no wiring is needed, and it will accept a 16-24V source if you already have a transformer at the door, topping the battery up while it is wired. Storage is 8GB eMMC on the device, and it pairs with mechanical chimes, HomeBase 2 or 3, MiniBase Chime, Alexa and Google Assistant.

Owners report real gaps. Battery life in everyday use is closer to two months than the four claimed, and a few doorbells shut down when the black faceplate sits in direct sun. Notifications also load slowly enough that some people miss a delivery, and the 160 degree view is narrower than several competing doorbells.

If your door already has proper transformer wiring and you would rather never think about a battery, the eufy Doorbell S330 is the cleaner fit. It has no monthly fee either, but it gives up the battery option entirely.

9. eufy Doorbell S330: Best for Homes With Existing Doorbell Wiring

Replacing an old wired doorbell? Start here. The eufy Doorbell S330 runs straight off 16-24V, 30VA power, so there is no battery to charge and no adapter to hide, and the included chime means the bell still rings inside the house.

Its useful feature is the three-second pre-roll, which records a short buffer before motion starts. Combined with Delivery Guard, which sends an alert when a parcel arrives and another when it is picked up, that buffer is the difference between a notification and an actual clip of the moment you care about.

The catch is alerts. It is motion-only, so it cannot tell a person from a passing car, a neighbour or a dog, and owners find the notifications noisy for that reason. It also does not support HomeBase, which rules it out if you are building a wider eufy system around a hub.

Video is 2K with HDR, which holds detail in the harsh daylight most front doors face, and 8GB of built-in storage keeps the running cost at zero. Compared with the eufy Video Doorbell E340, this one is quieter about power and louder about what it can integrate with.

10. eufy Smart Lock C220: Best for Fingerprint Entry

The best smart lock here if your hands are full. A fingerprint reads in under a second, and the self-learning AI fingerprint recognition improves as it recognises the same finger again and again, which is what separates a reader that works from one you stop trusting.

There are six ways in: fingerprint, app, keypad, physical key, Apple Watch and voice. The Wi-Fi is built into the lock, so unlike older smart locks there is no separate bridge to mount near the router. Eight AA batteries run roughly eight months on normal use.

Owners are happy with the install, which takes about 15 minutes on most standard deadbolts and usually needs no drilling. Two real issues come up: the reader is unreliable with wet or dirty fingers, and the keypad numerals wear off after heavy use, a fair complaint on any keypad lock with printed numbers.

For durability, the lock is BHMA Grade 3 certified after 100,000 cycles and rated IP53, and it works down to -22F. The body is aluminum, which feels lighter in the hand than a solid steel deadbolt. If fingerprint entry is not the draw and you want the cheapest route to a keyless door, the eufy Smart Lock C210 is the simpler pick.

11. eufy Smart Lock C210: Best for Straightforward Keypad Entry

The eufy Smart Lock C210 does one job cleanly: it turns a standard deadbolt into a keyless one. Five unlock methods cover app, keypad, physical key, Apple Watch and voice, and the built-in Wi-Fi handles remote access without any extra hardware.

Pick it for a rental, a side entrance or a home where nobody needs to program fingerprints. Owners treat the 15-minute no-drill install as the standout feature, since it fits most US deadbolts and keeps the existing strike plate. Four AA batteries are included.

What you give up is the fingerprint reader, and with it the fastest daily unlock. The app gives you access management, real-time notifications and an event history, which is where most of the value sits for anyone running a short-term rental.

Good to know: this model was previously sold as the E110 with no functional difference, so listings under the older name are the same lock. Owners also note that the touch keypad is hard to hit in the dark or with wet hands, and the aluminum body feels lighter than steel.

12. eufy Smart Display E10: Best for a Wall-Mounted Home Hub

The eufy Smart Display E10 is a wall-mounted 8-inch screen for a household that already runs eufy cameras and wants one place to look. Four live camera feeds sit side by side, so checking the front door, the driveway and the nursery takes a glance rather than a phone unlock.

It announces door activity out loud, with a live feed and a voice notification when someone rings, unlocks a door or is detected. Playback pulls from local storage with no waiting, and the touchscreen is deliberately plain enough that a child or an older relative can use it without help.

This is the newest product in the group, with 463 reviews and far less long-term owner history than the locks or the cameras. That matters when you are buying something that becomes the centre of a home security setup: the daily reports and facial or package recognition need a HomeBase 3.

It comes with a wall mount, a charging station, a 5V adapter and a Type-C cable, and it carries a 12-month warranty. Owners like the placement flexibility; the recurring note is that 64GB of local storage fills quickly if every camera records continuously.

How to Choose Eufy Products During Prime Big Deal Days

Start with the job the device does

Eufy splits into four groups that rarely compete with each other: robot vacuums, indoor and outdoor cameras, video doorbells, and locks and displays. Decide which room or which entry point is the problem before you compare anything. A family wanting cleaner floors and a family wanting to know who rang the bell need completely different products from the same brand.

Match robot vacuum power and dock to your floors

Below 8000 Pa suits hard floors with light carpet. 8000 Pa and up is worth it for deep pile or pets. Anything above 15000 Pa is a pet-hair machine rather than a general cleaner. Separately, a self-emptying station needs a permanent home: the eufy E25 station alone is 18.18 inches wide, so measure before you buy rather than after.

Check the Wi-Fi band and the app before you commit

Every product in this roundup joins 2.4GHz networks only. If your router combines bands under one name, your phone may drop the camera or robot while the rest of the house stays online. The eufy Indoor Cam E220 also drops to 1080P when viewed through HomeKit, so check that before you build a system around it.

Decide whether local storage replaces a subscription

Every camera and doorbell here can record without a monthly fee. The Indoor Cam E220 uses a microSD card up to 128GB, the SoloCam S340 has 8GB built in with no card slot, and both doorbells carry 8GB eMMC. If you want weeks of continuous recording rather than clips, the card option on the E220 is the more flexible of the two.

For doorbells, work out the power you already have

Battery or wired is the first fork. The eufy Video Doorbell E340 runs on a removable battery and will accept 16-24V if a transformer is already there. The eufy Doorbell S330 is wired only, needs 16-24V at 30VA, and will not pair with a HomeBase. Check the transformer rating before ordering either one.

How to Shop Eufy Deals During the Sale

On an eufy listing during Prime Big Deal Days, read the model number before anything else. The Smart Lock C210 was sold as the E110 with no functional difference, and robot vacuum names shift between generations, so two similar titles can be different machines. Check what the box contains, since stations, dust bags and cleaning solution are sometimes sold as bundles and sometimes not, and confirm whether the seller is eufy or Anker. Most offers on the event need a Prime membership, and pricing changes through the window, so the button below is the only reliable place to see the current number.

• Match the model number to the manual, not the listing title
• Confirm 2.4GHz Wi-Fi covers where the device will sit
• Decide between local storage and any paid plan before buying a camera
• Measure the base station footprint for any robot with a dock
• Check whether the transformer at your door meets the voltage requirement
• Look for what is in the box, since bundles and standalone kits differ
