If you are watching the eufy range during Amazon’s Prime Big Deal Days sale, the eufy 11S MAX is the one to put in your cart first. It carries the most owner reviews of anything on this list, runs at 55 dB, and its 2.85 inch body slides under most sofas. Bigger homes do better with the eufy E25 Robot Vacuum, and mixed carpet and hard floors suit the eufy X10 Pro Omni. Prime Big Deal Days runs October 6-7, 2026, and most of these offers need a Prime membership.
Everything below is worth watching during the sale, not a confirmed markdown. Prices on eufy devices move hour by hour through the event, and some listings change shape mid-sale, so check the model number before you compare two pages.

How We Chose
We compared the specs that decide these purchases, then read the owner review themes on each listing: noise levels for the vacuums, night vision range and storage for the cameras, battery claims against reported battery life for the doorbell. Everything here was checked against the product data on October 2026.
1. eufy 11S MAX: Our Editors’ Choice
- Very quiet at 55 dB
- Slides under low furniture
- 100 minutes of runtime
- BoostIQ adapts suction fast
- No WiFi or app mapping
- Random cleaning pattern with no virtual walls
- Powers down silently when snagged on cords
The quietest machine in this list, and the one with the deepest well of owner feedback: more than 59,000 ratings at 4.3 stars. That matters on a vacuum, because the alternative to a loud robot is not running it while the baby naps.
Its 2.85 inch profile is the number to check against your own furniture. Owners buy it for exactly that reason, sliding it under low-slung sofas and coffee tables that taller robots cannot reach.

- BoostIQ raises or drops suction within about 1.5 seconds as it moves between floor types
- Anti-scratch tempered glass top with infrared drop sensors
- 600 ml dustbin and a washable filter
- 100 minutes of runtime on hardwood, then it returns to its dock
Skip it if you want a floor map. There is no app and no virtual wall, so the only way to keep it out of a corner is a physical barrier. The eufy E25 Robot Vacuum is the step up when mapping and a mop matter more than slim height.

Good to know: owners report the unit going quiet when it snags on a cable or a thin furniture leg, with no alert on the remote. Ten minutes of tidying before each run prevents most of those stalls.
2. eufy E25 Robot Vacuum: Top Rated for Whole-Home Cleaning
- Highest rating in this roundup
- 20000 Pa lifts embedded pet hair
- Station empties washes dries and refills
- Maps up to 5 floor plans
- CornerRover arm cleans baseboards
- Proprietary cleaning solution with no alternative formula
- Station re-washes the mop on every floor change
- Heaviest unit here at 37.5 lb
At 4.4 stars across 54,000 ratings, this is the highest-rated product in the roundup. It is also the only one that does the whole job on its own: the station empties the bin into a 3L bag, washes the mops, dries them at 50C and refills the water tank.
Suction is the headline figure and the reason pet owners gravitate here. Twenty thousand pascals pulls hair out of carpet pile rather than just off the surface.

Owners with big homes and several pets like the mapping. It holds up to five floor plans and switches between them automatically, which the eufy X10 Pro Omni also does but at a lower suction figure.
- HydroJet roller mop refreshes twice per second to cut cross-contamination between rooms
- Mop lifts 10.8 mm and climbs 21 mm thresholds
- 125 minute runtime at 61 dB or below in max mode
- Works with Alexa, Google Assistant and Siri through the eufy app on 2.4 GHz
Pick something else if your floors are sensitive. The cleaning solution is proprietary with no supported substitute, and owners mention a slight waxy residue it can leave behind. It also weighs 37.5 lb, which is a real consideration for a second-floor station.

Good to know: owners are frustrated that the wash cycle re-triggers every time the machine changes level, and it cannot be overridden in the app. Run it floor by floor and you will fight that behaviour all night.
3. eufy X10 Pro Omni: Best for Mixed Floors
- Mops lift 12 mm so carpets stay dry
- No-go zones and virtual boundaries
- Station washes dries and self-empties
- 3L tank covers 2000 sq ft
- Detangling roller brush for pet hair
- Bulky 26.4 lb unit and a large base
- Mirrors confuse the map
- Setup relies on an online PDF
Households with carpet in the bedrooms and tile in the kitchen are what this machine was built for. The dual rotating mops lift 12 mm the moment carpet is detected, so it does not drag a wet pad across your rugs.
The mapping is the other reason to stretch to this one over the eufy 11S MAX. AI.Map 3.0 lets you draw no-go zones around pet bowls and cables, and AI.See recognises more than 100 object types rather than only cables and shoes.

- 8,000 Pa suction with automatic carpet detection
- All-in-one station: mop washing, 45C heated-air drying and a 2.5L dust bag
- 3L clean water tank for mopping up to 2,000 sq ft
- 2.4 GHz Wi-Fi only, so check your router before you buy
Two things catch people. The unit and base together weigh 26.4 lb and eat a genuine chunk of floor space. And the mapping occasionally invents rooms when it sees a mirror, which owners fix by covering the reflective surface or deleting the extra room in the app.

Setup is the part owners mention first, and it is thinner than the feature list suggests. There is no printed guide beyond the safety booklet, so the full walkthrough lives in an online PDF and you will want your phone within reach while you unbox it.
4. eufy SoloCam S340: Best for Solar Power
- Solar panel that you can remove and reposition
- 360 degree pan and tilt with no blind spots
- 3K detail out to about 40 ft
- 8GB built-in storage with no monthly fee
- About 7 minute screw-in install
- Night vision range of only about 6 meters
- Solar panel needs wiring and can read as partial backup
- Extended storage and some AI tiers cost extra
Covering a driveway or a back gate without running a cable is what this camera is for. The solar panel detaches, so you can mount it where the sun actually reaches rather than where the bracket happens to fit.
The pan and tilt head gives full 360 degree coverage with no blind spots, and the dual-lens setup holds 3K detail out to about 40 ft with 8x hybrid zoom. That is enough to identify a face at a gate, not just a shape.

- Built-in 8GB local storage, so basic recording carries no monthly fee
- Colour night vision on top of standard infrared
- AI detection and tracking handled on the camera
- Alexa compatible, screw-in mounting bracket included
The honest limit is night vision, which owners put at roughly 6 meters. That suits a porch or gate at close range and falls short for a long driveway after dark. If the camera sits far from the house, look at the eufy Video Doorbell E340 instead, which handles colour night vision out to 16 ft.

Good to know: the word wireless on this listing is misleading to some buyers. The camera runs without a power lead, but the solar panel still needs wiring back to it, and a few owners report treating the panel as backup rather than a full-time power source in shaded positions.
5. eufy Video Doorbell E340: Best for Package Watch
- Second downward camera aimed at the doorstep
- 8GB local storage with no subscription
- Works on battery or hardwired at 16-24V
- Colour night vision out to 16 ft
- Keeps your existing mechanical chime
- Battery life closer to two months than four
- App can lag on older HomeBase hardware
- Sensors still trigger on passing cars
Two cameras instead of one is the whole idea here. The upper lens handles visitors head to toe, and the downward lens watches the mat where parcels land, which is the view most single-lens doorbells miss entirely.
Package detection is the feature people mention most, paired with 8GB of local storage that needs no subscription. It pairs with a HomeBase 2 or 3, a MiniBase Chime, Alexa or Google Assistant, and it can keep an existing mechanical chime rather than forcing a new one.

- 2K FHD main sensor with a 160 degree viewing angle
- IP65 rated for outdoor exposure
- Dual-light system for colour night vision to 16 ft
- Quick-release battery pack or a hardwired run to 16-24V
Battery life is the complaint owners repeat most. The stated figure is four months; in practice reviewers report closer to two. If you run it on battery, plan for a swap every other month or hardwire it during the sale while you are already at the door.

Placement matters more than the settings do. Motion zone and sensitivity adjustments still catch passing cars, and owners on sun-facing doors report the unit overheating and shutting down. A shaded side of the porch is the kinder position.
6. eufy Smart Lock C220: Best for Renters
- Retrofits over a standard deadbolt in about 15 minutes
- Built-in Wi-Fi so no separate bridge
- Fingerprint unlock in under a second
- Up to 8 months on 8 AA batteries
- BHMA Grade 3 certified
- Fingerprint accuracy suffers with wet or dirty fingers
- Needs a deadbolt bore under 54 mm
- Battery life varies with how often you unlock
Apartment doors and rented rooms rule out anything that needs drilling, and this lock slides over an existing deadbolt in roughly 15 minutes. You keep the keyway and take the whole unit with you when you move.
The design decision that saves money is built-in Wi-Fi. Most smart locks need a separate bridge plugged into the same wall, and the owners who skipped that step are the ones who like this model most.

- Six unlock methods: fingerprint, app, keypad, physical key, Apple Watch and voice
- Self-learning fingerprint recognition that improves with use
- IP53 waterproof and rated from minus 22F to 158F
- Box includes 2 keys, 8 AA batteries and the mounting hardware
Two checks before you buy. Measure the deadbolt bore, because a bore over 54 mm needs the supplied spacer removed, and expect occasional fingerprint failures with wet or greasy hands. Owners also report the occasional app hiccup after months of use.

Bought alongside a doorbell, this one keeps everything on one screen: the eufy Video Doorbell E340 and this lock share the same app, so a delivery alert and a locked door sit in the same place.
7. Ring Wired Doorbell 4K Pro: Best for 4K Doorbell Video
- Retinal 4K sensor is the sharpest here
- Low-Light Sight holds colour in porch light
- 10x zoom reads details at distance
- Hardwired so there is no battery to swap
- 3D Motion Detection cuts false alerts
- Video history and descriptions need a Ring subscription
- Weak on 2.4 GHz mesh networks
- Limited documentation for older installs
Not an eufy device, and included here because most people weighing an eufy Video Doorbell E340 compare a rival first. This one has the sharper sensor: a 4K panel at 2880 by 2880 with 10x zoom, which the E340’s 2K main camera does not match.
It is hardwired, so there is no battery charging and no battery anxiety. Colour holds up under ordinary porch lighting, dropping to black and white only in total darkness.

The trade-off runs the other way from eufy. Video history and video descriptions sit behind a Ring subscription, while the E340 records locally to 8GB with no fee. Owners also note that installing over an existing chime means giving up that chime, since the included mini chime sounds thin by comparison.
One more check: several owners report unstable behaviour on 2.4 GHz mesh networks, with slow live view and dropped recordings. If your router is mesh-based, the eufy doorbell is the safer bet during the sale.

Before ordering, measure the existing chime wiring. Documentation for this model is thin, and older Ring-compliant installs can need a third-party adapter that is not in the box.
8. REOLINK Doorbell PoE: Best for Wired Homes
- PoE carries power and data on one run
- Records straight to microSD or an NVR with no fee
- Pre-roll captures 6 seconds before the event
- Chime V2 included with 10 tunes
- 100 ft night vision and IP65 rating
- Power supply sold separately
- Wi-Fi is not supported at all
- Third-party NVRs will not work
If you are already running Ethernet through the house, this is the doorbell that makes sense. One cable carries power and video, and it keeps recording through an internet outage because nothing depends on your Wi-Fi.
The 4:3 aspect ratio at 2K is unusual and genuinely useful on a doorbell, since the taller frame captures a person head to toe and the floor below in one frame.

- Storage options run from microSD up to 512GB to an NVR with 2TB or 4TB, plus FTP and NAS
- Humanoid detection filters out non-human passers-by with adjustable zones
- Chime V2 ships in the box with 10 tunes and voice message presets
- 180 degree diagonal field of view with HDR and 3D noise reduction
Be honest about your setup before buying. The power supply is not included, Wi-Fi is not supported at all, and third-party NVRs will not pair with it. If none of that fits your house, the eufy Video Doorbell E340 works over ordinary Wi-Fi with no cabling.

Owners who already run PoE describe the connection as rock-solid and the pre-roll as the feature they did not know they wanted. Everyone else should read the wiring requirements twice.
How to Choose Eufy Smart Home Devices During Prime Big Deal Days
Start with the hub and app, not the camera
Decide which app you will live in before you buy anything. The eufy SoloCam S340 and the eufy Video Doorbell E340 both run standalone with built-in storage, but their extra AI and long-retention tiers live inside the eufy ecosystem. If you already own eufy cameras, a HomeBase 2 or 3 unlocks options a standalone unit will not have.
Battery, solar and wired are three different commitments
The SoloCam S340 runs on a removable solar panel, the E340 runs on a quick-release battery or hardwiring at 16-24V, and the smart lock runs on eight AA cells. If you would rather not think about it, wire the doorbell during the sale while a handyman is available and skip the battery question entirely.
Work out what local storage really covers
The most common eufy question is whether there is a monthly fee. Both the S340 and the E340 record to built-in storage with no recurring charge, which is the main reason buyers accept lower-resolution footage than some rivals. Cloud backup and extended retention are separate paid tiers, so decide now whether you need more than a rolling local buffer.
Robot vacuum base stations need floor space
Count the footprint before you fall for a station. The eufy X10 Pro Omni and its base weigh 26.4 lb together, and the eufy E25 Robot Vacuum is heavier still at 37.5 lb. Both need a flat spot near an outlet and an outlet you can reach, not a corner you plan to forget.
Check the model number, not just the photo
eufy reuses product names across generations, and two listings with near-identical titles can be different hardware. The model number is the reliable identifier: T8170 on the SoloCam S340, T8214 on the E340, T8506 on the smart lock, AK-T2126 on the 11S MAX. Also confirm whether a page lists the mop pads and cleaning solution in the box, because the X10 Pro Omni ships without its cleaning solution.
How to shop these deals during the sale
On a listing like these, read the model number in the specifications block, the size or colour variant in the title, and what the box actually contains before comparing two pages. Most of these offers need an active Prime membership, a free trial counts, and the pricing shifts throughout the event.
- Match the model number on every comparison, not the product photo
- Decide battery, solar or wired before you compare features
- Confirm local storage covers what you want without a subscription
- Measure the station footprint and the deadbolt bore before ordering
- Check the seller and shipper line on the listing
- Look for an on-site coupon that only appears after you clip it
Frequently Asked Questions
When does Amazon Prime Big Deal Days run in 2026?
Prime Big Deal Days runs October 6-7, 2026. Amazon confirmed those dates for the autumn event. Early offers often appear in the days before the window opens, and a few linger afterwards, but the main offers are live across the two days themselves.
Is Amazon Prime required to use Prime Big Deal Days offers?
Most Prime Big Deal Days offers require an active Prime membership, and a free trial counts. A small number of deals run for everyone, but the strongest offers on eufy cameras, doorbells and robot vacuums are usually tied to the membership.
Which eufy deals are worth watching most during the sale?
The eufy 11S MAX, the eufy E25 Robot Vacuum and the eufy SoloCam S340 are the three worth watching most, covering a quiet vacuum, a self-emptying vacuum and mop and a solar camera. They carry the largest owner review counts and the broadest coverage of home sizes.
Do the eufy SoloCam S340 and Video Doorbell E340 need a monthly subscription?
Not for basic recording. Both store footage on built-in memory with no recurring charge, which is the main reason owners accept lower resolution than some rivals. Longer retention and cloud backup sit in separate paid tiers, so decide how much history you actually need before you pay for anything.
How can buyers tell whether two eufy listings show the same model?
Compare the model number in the specifications block rather than the product title. For example T8170 identifies the SoloCam S340 and T8214 identifies the Video Doorbell E340. Also check the colour, the bundle contents and whether the seller ships the item themselves.
What are the common problems with eufy robot vacuums?
Owners most often report the X10 Pro Omni mapping extra rooms around mirrors, the E25 re-washing its mop on every floor change, and both units being heavy and bulky to move. Cord snagging and silent stalls come up often on the non-mapping 11S MAX.
Final Verdict: Best Amazon Prime Big Deal Days Eufy Deals
Buy the eufy 11S MAX as our Editors’ Choice if you want the quietest machine here and can live without a floor map. The eufy E25 Robot Vacuum is the one to watch if you have pets, big rooms and patience for a proprietary cleaning solution. For mixed flooring, the eufy X10 Pro Omni earns its place with 12 mm mop lift and no-go zones.
The eufy SoloCam S340 fits a driveway or gate with no cable run, the eufy Video Doorbell E340 covers visitors and parcels in one unit, and the eufy Smart Lock C220 suits anyone who cannot drill. If you want a sharper doorbell sensor, look past the brand and compare the Ring Wired Doorbell 4K Pro and the REOLINK Doorbell PoE, which is the right call if your house already runs Ethernet.
