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

The eufy 11S MAX is the one we would watch first during this sale because it does the least and does it well: a 2.85 inch tall body that slides under low furniture, 100 minutes of runtime and a remote control, with no app and no Wi-Fi credentials to hand over. Households that want a dock which empties the bin and washes the mop should look at the eufy C28 instead, and anyone who cleans mostly carpet can push up to the eufy E25 for 20,000 Pa of suction.

Prime Big Deal Days runs October 6-7, 2026, and most offers on the brand require a Prime membership, with a free trial counting. The picks below cover both halves of the eufy catalogue: five robot vacuums, two indoor cameras, one solar outdoor camera, a video doorbell and a smart lock.

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

The 11S MAX takes the top slot on practicality rather than specification. Nothing else in the cleaning group is this slim or this light at 6.35 lb, or this easy to live with in a flat where a charging dock would be in the way.

The C28 is the middle ground, with a self-cleaning HydroJet roller and a station that empties the bin, washes the roller and refills the tank. The E25 is the one to hold out for if carpet is the problem, since its suction figure and its side arm are the highest in this group.

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

Every machine here is a plug-in or self-charging model sold on Amazon, and every camera in the group records to local storage rather than requiring a monthly plan. The differences that actually matter sit in the second column: how much upkeep the dock takes, and whether the camera needs a hub.

How We Chose

We compared the specifications that decide these purchases: body height, suction, runtime, dock maintenance, night coverage, storage options and connectivity. Ratings and owner review themes came from Amazon listing data, checked on October 2026. No price appears here; use the buttons to see the current figure.

1. eufy 11S MAX: Editor’s Choice for Quiet, Low-Profile Cleaning

The one to watch first if your floors are hard and your furniture sits low.

At 2.85 inches tall and 6.35 lb, this is the slimmest robot here, which matters in a living room where the sofa sits about three inches off the floor. It runs for up to 100 minutes, covers a 12.8 inch path and holds 600 ml of dust, with a washable filter and a tempered glass top that survives being brushed past.

The remote-only design is the point rather than a compromise for a lot of shoppers. There is nothing to pair, no account to create and no app sitting half-configured on a guest network, which makes it a reasonable first robot vacuum for a flat where the router sits in a hallway and the Wi-Fi password belongs to someone else.

Owners report the trade-off clearly. The cleaning path is random, so there is no room map and no way to tell it to skip the kitchen, and several reviews mention it driving under a bed leg and stopping without a sound. The 600 ml bin also means a mid-sized home will need emptying during a run.

Compared with the eufy Omni C20, which is nearly as slim at 3.35 inches and adds an app plus a self-emptying station, the 11S MAX is for people who would rather empty a small bin than install a dock. If you want mopping in the same pass, the eufy C28 is the step up.

Two details catch people out here. The model answers to a physical remote only, so a scheduled clean while you are out means someone else pressing a button, and the filter needs tapping out every few weeks in a home with a shedding cat. It is rated for hard floors, tile and medium-pile carpet.

2. eufy C28: Best Value for Pet Homes That Hate Upkeep

The pet-hair answer, and a step up from the basics.

The mop is the part worth understanding. A 28 cm HydroJet roller spins at 270 RPM with 24 water ports, and a built-in scraper pushes the dirt into a separate tank while the robot keeps working, so you are not stopping every ten minutes to rinse a pad. The brush is designed not to wrap hair up to 30 cm long.

Suction is 15,000 Pa with an automatic boost when carpet is detected, runtime is up to 140 minutes and the dust bag is a 3 litre unit. The station empties the bin, washes the roller, dries it with warm air and refills the clean water tank.

What owners still do is refill the water tank and change the bag when the light says so, and the station is big: 15.47 by 14.6 by 18.14 inches for the whole assembly, which needs a clear corner of a room rather than a gap under a cupboard.

It sits between the 11S MAX and the E25. The 11S MAX is quieter and smaller with no dock, and the E25 pushes suction to 20,000 Pa with an edge arm, so the C28 is where most pet households should land.

Picture a house with two shedding dogs and a tiled kitchen. Navigation here is LiDAR with no cameras fitted, which keeps the privacy profile simpler than camera-based robots, and at 24 lb the robot runs at about 55 dB, quiet enough to leave going while you work from home.

3. eufy E25: Premium Pick for Carpet and Multi-Pet Homes

The strongest suction on this list, and the one that suits a house full of pets and thick carpet.

20,000 Pa is roughly a third more than the C28, and review themes focus on what that does in practice: lifting dirt pressed into carpet fibres and pulling allergens out rather than moving them around. The HydroJet system flushes the roller with clean water twice a second, so the mop arrives at each room already rinsed.

The corner arm is the quieter story. It extends to scrub along skirting boards and furniture legs, and laser navigation stores up to five floor plans, so a two-storey house does not need remapping when the robot changes floor.

The most repeated complaint is not performance but the cleaning solution. There is a single formula, it comes in proprietary cartridges, and owners report a waxy residue left on some hard floors when a cartridge failed to dispense. Check what your own floor needs before assuming it is required.

It is also the heaviest item here at 37.5 lb for the robot and station together, so plan the lift before the box arrives. Connectivity is 2.4GHz only, which is fine unless your router has split the two bands with different names.

Compared with the C28, you are paying for suction, edge cleaning and the corner arm rather than for a different class of mop. Buyers on hard floors alone can get a comparable routine from the eufy Omni C20 at a step down.

Runtime is 125 minutes and noise stays at or under 61 dB in maximum mode, which is louder than the 11S MAX but well inside normal conversation range. The robot and station together come to 37.5 lb, the heaviest pairing in this list, so the corner you put it in needs a solid floor and a clear path.

4. eufy Omni C20: Best for Vacuuming and Mopping in One Pass

The pick when the goal is one machine doing two jobs across mixed flooring.

Rather than vacuuming and then mopping as separate passes, this model does both at the same time from the app, which on a hard floor with children and a dog is the difference between running it once in the evening and running it twice. The mop head applies 6 newtons of downward pressure at 180 RPM, enough to shift dried marks rather than only fresh spills.

Its 3.35 inch body is taller than the 11S MAX but still clears most low sofas, and iPath laser navigation stores three floor maps. The 3.1 L bag is rated at up to 60 days, and the tanks are transparent so you can check the clean and dirty water at a glance.

Two things catch people out. Boundary strips are not in the box and do not fit this model, so a no-go zone drawn in the app is the only boundary option, which matters in a house with a toddler or a climbing cat. And the mop dries at room temperature rather than with heated air, which tells on you in a humid house or under a closed door.

Against the C28, the trade is suction and mop engineering for footprint: 7,000 Pa here against 15,000 Pa and a self-scraping HydroJet roller there. If your home is mostly carpet, skip past this one.

The station dries the pads with room-temperature air, the whole machine is 19.9 lb, and no-go zones plus a child safety lock are set in the app.

5. eufy X10 Pro Omni: Best for Homes Full of Cables and Clutter

A room full of charging leads, phone cables and toys on the floor is where this machine earns its asking figure. AI.See identifies more than 100 object types and the mapping lets you draw no-go zones around them, so the robot stops hunting the same cable every run.

Suction is 8,000 Pa, on the modest side next to the E25, but the mops are dual and auto-lift 12 mm over carpet. The station washes both and dries them with 45 degree heated air, and the 2.5 L bag needs changing roughly every two months while a 3 L clean water tank covers about 2,000 sq ft.

Owners mention the physical side more than the software. At 26.4 lb, getting the station up a step or into a cupboard is a two-person job, and the box has no printed manual, only a downloadable PDF. The eufy cleaning solution is also not included.

Another recurring detail: mirrors on the floor can split one room into two on the map, which then needs tidying in the app. It is a five-minute fix, but it happens on day one.

The eufy C28 covers similar ground with a single mop and higher suction, so choose this one for obstacle handling and the C28 for raw carpet cleaning. Both are large; the slimmest option in the list is the 11S MAX.

The rating sits a little below the other vacuums here, and reliability or support problems come up in a small number of reviews, so a longer ownership mindset helps.

6. eufy Cam E220: Best for Watching Cats and Dogs Without a Subscription

A dark room at two in the morning is the test. On-device AI sorts out humans, pets and general audio events as separate recordings, so a creak does not send you to a clip of a chair moving, and 2K resolution keeps faces readable across the room.

It pans and tilts through 360 degrees and follows motion on its own, so a cat moving from the sofa to the window stays in frame. Footage goes to a microSD card you supply, with no monthly fee attached, and two-way audio lets you talk to a dog that is barking at the door. HomeKit, Google Assistant and Amazon Alexa all work with it.

The honest weakness is detection reliability. Owners report that person detection struggles at night and at longer distances, and that a 256GB card mentioned in some listings is not accepted, so buy the 128GB card and check the spec before ordering. A slow, laggy app comes up in a number of reviews too.

Against the eufy Cam E30, which records in 4K and catches crying, the E220 is the value pick for a living room or a hallway. If image detail at night is what you are buying, go to the E30 instead.

It is 2.4GHz only, worth checking before you buy, and the IP65 rating covers damp spots rather than an outdoor mount.

7. eufy SoloCam S340: Best for Wire-Free Outdoor Coverage

For a driveway, a side wall or a cabin where running cable is not happening.

Mount it on the wall that faces the street and the solar panel does the rest. Two lenses give 3K detail with 8x zoom out to about 40 ft, the pan-and-tilt head covers a corner instead of leaving a blind spot, and 8GB of on-board memory means no monthly fee. Installation takes about seven minutes with no wiring.

The panel is removable, so if the wall turns out to be shadier than expected you can move it later without redoing the mount. A battery sits behind it as backup for cloudy spells.

Set expectations on night coverage: the listed night vision range is about 6 meters, which is fine for a doorway and short for a long driveway. A shaded north-facing wall will also slow charging, and reviews of outdoor eufy models commonly point at seal and durability over a few seasons.

This is the only outdoor camera in the group, so the comparison is with the eufy Cam E220 rather than a like-for-like rival: the S340 trades resolution indoors and long night range for being outside at all.

Mounting notes, since this is the outdoor piece:

• At about 630 g and 4.72 inches tall it needs a solid wall or a firm post, not a thin fence panel.
• A sunlit face of the building will charge faster than a shaded one, which decides how often the panel needs repositioning.
• A 4.2 average with a higher one-star share than the indoor models makes the seller and warranty terms worth reading closely.

8. eufy Doorbell E340: Best for Porch Package Watch

Most people buying a doorbell want one thing: to know a parcel arrived. The lower camera here points down at the step where couriers leave them, and package detection then tells you whether something was delivered, collected, or left too long.

The upper lens looks at faces from head to toe, so a visitor is on film as well as a box. Footage is 2K in both directions with a 160 degree view, and 8GB of internal storage means no subscription is needed. Colour night vision reaches about 16 ft using a dual-light system, and the quick-release battery lets you pop the unit off the mount to charge.

Owners report battery life closer to two months than the advertised four, particularly on a busy street where every passer-by wakes it. Notification response can lag, and a south-facing door in full sun has been reported to push the unit into shutting down around 120F.

Motion zones are not perfect either, and passing cars still trigger some of them. If your door faces a pavement rather than a garden, plan to trim zones carefully after install.

Compared with the eufy SoloCam S340, the doorbell gives you visitors and parcels in one unit but no wide outdoor sweep. Buyers who want a chime inside the house can pair this with a HomeBase 2 or 3.

It carries an IP65 rating, weighs about 1.1 lb, and can be hardwired to a 16-24V source if you would rather not charge it at all.

9. eufy Lock C220: Best for Retrofits and Rental Doors

The answer for a front door you cannot drill into, or a deadbolt you do not want to replace.

It installs over an existing standard deadbolt in about a quarter of an hour, which is why it keeps a physical key cylinder as one of its six unlock methods. Fingerprint reading is the fast one, and the self-learning profile improves as your family uses it.

The detail that matters most is the Wi-Fi built into the body. There is no bridge or hub to mount, so remote unlocking and real-time notifications work the day it goes on the door, with eight AA batteries rated at roughly eight months.

• BHMA Grade 3 certified after more than 100,000 lock cycles, and rated IP53 for weather from -22F to 158F, so an exposed porch is fine.
• Six unlock routes: fingerprint, app, keypad, physical key, Apple Watch and voice.
• Retrofits most standard deadbolts in about 15 minutes without new wiring.

The practical warnings are specific rather than alarming. If your bore is under 54 mm the included spacer has to be removed before fitting, not every European cylinder profile is compatible, and the fingerprint sensor wants cleaning, since grime on the pad is the usual cause of a refused read.

Compare with the eufy Doorbell E340 if your priority is seeing who is outside rather than letting people in. Together they pair through the eufy app, and routines can lock the door when the camera spots someone at the step.

The body is aluminium and the finish is polished black, and the app, keypad, Apple Watch and voice assistant all unlock without touching the keypad.

10. eufy Cam E30: Best for Nursery and Playroom Watching

Try it in a nursery or a playroom, where the detail matters more than the shape. The on-device AI sorts out humans, pets, general audio cues and crying as separate events, so a noise in the night does not send you to a recording of a chair moving, and the pre-event buffer saves the seconds before a trigger.

4K is what makes that useful in a dark room, and a built-in spotlight switches between colour and infrared night vision. Quick Focus Tap plus a panoramic view let you reframe from the app instead of moving the camera, and storage is a local microSD card up to 128GB with no monthly fee.

Two practical notes. A high-endurance UHS-1 card is needed for reliable 4K writing, and playback from that card is slow because the footage is being decrypted on the fly, so allow a moment when you are checking something at 2am.

Some owners also report the occasional detection dropout and a live view that loads slowly on a weak network, and the head is a little bulky for a narrow shelf.

Against the eufy Cam E220, the E30 buys resolution, the crying alert and the pre-event buffer, while the E220 keeps the outlay lower. If the room is dark at night, the E30 is the better buy.

HomeKit output is limited to 1080p, and it pairs with a HomeBase 3 if you would rather run one hub for several devices than a card in every camera.

How to Choose Eufy Smart-Home and Security Products During Prime Big Deal Days

Check the Wi-Fi band before you fall for the percentage

Several of the devices in this list, including the eufy E25 and the eufy Omni C20, are 2.4GHz only. If your router splits the two bands onto different names, joining the 2.4GHz network is a two-minute job and saves an afternoon of pairing failures.

Decide how much upkeep the dock takes

Self-emptying and self-washing stations mean far less hands-on work, but they also mean water tanks, dust bags and a large footprint. If you have nowhere to put an 18 inch tall station, a simpler machine like the eufy 11S MAX is the saner purchase.

Work out your storage plan before buying a camera

Local microSD storage means no monthly fee but the card is yours to buy and back up yourself. A HomeBase 3 is optional for these cameras, useful if you want one hub for several devices, and the eufy Lock C220 needs no hub at all because Wi-Fi is built in.

Buy the camera to match the room, not the resolution

The eufy Cam E30 at 4K earns its extra clarity in a dark nursery, while the eufy Cam E220 is plenty for a lit hallway. The eufy SoloCam S340 is the outdoor option, and its roughly 6 meter night range tells you where to mount it.

Match the vacuum to your floor and your pets

Hard floors and low furniture point to the eufy 11S MAX or the eufy Omni C20. Carpet and long pet hair point to the eufy E25, and a house full of cables points to the eufy X10 Pro Omni, where obstacle avoidance earns its keep.

How to Shop Eufy Deals During the Sale

Model codes change often in this range, so check that the listing is the model you read about rather than a near neighbour with similar speeds and a different dock. Look at what is in the box, since bundles with a HomeBase or a second camera are not always cheaper per unit than two singles.

Most offers on this brand need a Prime membership during the event, and prices move through October 6-7, 2026.

• Confirm the 2.4GHz network is joined before ordering anything.
• Decide local card storage or a hub before buying cameras.
• Check whether a dock is worth the space in the room you have.
• Read the box contents for bundles rather than trusting the unit count.
• Apply any coupon manually and compare the final figure at checkout.
• Note the model number, since replacements are not always like-for-like.

Frequently Asked Questions

Final Verdict: Best Amazon Prime Big Deal Days Eufy Deals

Buy the eufy 11S MAX if your home has hard floors, low furniture and no interest in apps, since its 2.85 inch body and 100 minute runtime handle a problem none of the other robots here address. For the middle of the range, the eufy C28 is the better fit, with a self-cleaning HydroJet roller and a station that empties the bin, washes the roller and refills the tank. Push further for the eufy E25 if carpet and long pet hair are the issue.

Buy the eufy Omni C20 for one-pass vacuuming and mopping, the eufy X10 Pro Omni for obstacle avoidance in a cluttered house, the eufy Cam E220 for everyday indoor pet watching, the eufy SoloCam S340 for outdoor coverage without cable, the eufy Doorbell E340 for package deliveries, the eufy Lock C220 for a door you cannot drill, and the eufy Cam E30 when 4K detail in a dark room is the reason you want a camera.

Before you commit, check the model number on the listing so you are not swapping one robot for a lookalike with a different dock.
