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

If you want one eufy product that quietly does more of the work than anything else in this list, the eufy Omni C20 is the one to watch. It empties its own bin, washes and dries its mop pads and still slides under the low furniture most robots cannot manage, and at 4.4 stars across more than 54,000 reviews it holds the strongest combination of rating and owner history here.

For a smaller footprint, the eufy 11S MAX is the pick when your rooms are tight and you do not want an app in your life. The eufy X10 Pro Omni is the bigger, heavier answer for larger homes with mixed flooring. Amazon Prime Big Deal Days runs October 6-7, 2026, and offers change through the event, so use the buttons below to see the current price on each one.

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

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

How We Chose

We compared the specs that actually separate these products: suction and dock behaviour for the vacuums, resolution, storage and power options for the cameras, and what each one costs you in ongoing fees. Alongside that we read owner reviews and ratings on Amazon, checked for the same complaints showing up again and again, and confirmed the listing details on October 2026.

1. eufy Omni C20: Editor’s Choice for Hands-Off Floor Care

The most complete cleaning setup in this list, and the one most people will keep using.

Most robot vacuums empty themselves and then leave you a damp pad to deal with. The Omni Station here washes the pads, dries them and empties the bin into a 3.1 liter bag that owners say lasts up to about 60 days, so the honest maintenance routine is emptying a bag twice a month.

What is unusual is the 3.35 inch body. In a house with low sofas, that slimness matters more than raw suction, and owners say it covers hardwood, tile and medium carpet in one pass. The mop runs at 6N of downward pressure and 180 RPM, and it lifts off the carpet automatically.

• 7,000 Pa suction with BoostIQ, which adjusts within a couple of seconds of hitting a new floor type
• iPath laser navigation with up to three floor maps, plus no-go zones and scheduling in the eufy Clean app
• Alexa, Google Assistant and app control, and a washable high-performance filter
• 132 minutes of runtime per charge, then it recharges and picks up where it left off

Owners report the main gripe is not cleaning performance but setup: the station is heavy and bulky, and it lives on your floor from then on, so pick a spot with clearance before you unpack it. Two other owners-common notes are that the machine joins 2.4GHz networks only, and that the boundary strips sold for other models do not fit this one, so plan your no-go areas in the app instead.

Compared with the eufy X10 Pro Omni, the difference is power and size. The X10 pulls more suction, detects more obstacle types and dries its pads with heated air, but it weighs 26.4 lb and needs more floor space around its dock. If your floors are mostly hard surface and you want the smallest footprint that still mops, the Omni C20 is the better fit. If you have thick carpet, stairs or a lot of pet hair, move up to the X10.

A second thing worth knowing before you commit: the mop and vacuum run at the same time on this model, so treat it as a combined pass rather than a vacuum-then-mop cycle. That is faster on a mixed floor, and it is why owners of hard-floor homes tend to be its happiest users.

2. eufy 11S MAX: Best for Small Spaces

Buyers pick this one for a reason that has nothing to do with features: it is 2.85 inches tall, so it goes under the beds, sofa overhangs and low kitchen units that stop every disc-shaped robot in its tracks.

That slimness is the whole argument. There is no app, no Wi-Fi, no mapping and no voice assistant. You point the remote at it, pick a mode and it works. For a flat, small apartment with hardwood and a bit of medium-pile carpet, that simplicity tends to outlast the cleverness of smarter machines, and the tempered glass top takes the scuffs from under-furniture cleaning without marking.

With about 55 dB of operation and up to 100 minutes of runtime on hardwood, it is also the quietest of the three vacuums here, which matters in a home with sleeping children or a home office. The 600 ml bin is smaller than the Omni C20’s setup, so you will empty it more often.

• BoostIQ raises suction within about 1.5 seconds when it detects a harder surface
• Infrared obstacle sensors and drop-sensing technology handle edges and stairs
• A self-charging dock takes it back to charge on its own
• Single-side brush design, washable filter and a cleaning tool in the box

The trade-off is the one owners name constantly: it does not map rooms, so it cleans by bouncing around, and in a home with lots of obstacles you will sometimes find it re-cleaning an area it already covered. It also does not mop. If you want mopping or you want to check in from your phone while you are out, the eufy Omni C20 is the step up.

Good to know: with almost 60,000 reviews at a 4.3 average, this is the most reviewed product in the list, and the number of replacement parts available for it is part of why owners keep it running for years rather than replacing it.

3. eufy X10 Pro Omni: Premium Pick for Large Mixed-Floor Homes

Buy the X10 Pro Omni when your home has both hard floors and thick carpet, pets, and enough square footage that a half-finished clean is not good enough.

This is the most capable machine eufy puts on the floor here. Suction climbs to 8,000 Pa, the AI.Map 3.0 system builds multi-floor maps and honours no-go zones and virtual boundaries, and AI.See obstacle avoidance is trained on 100-plus object types, which is the feature owners credit most for fewer cables and toys wrapped around the roller brush.

The 12 mm MopMaster auto-lift is the detail that changes daily use. The pads rise the moment carpet is detected, so you get mopping and carpet care in one run rather than choosing between them. The station then washes the pads and finishes with 45C heated air, and a 3 liter clean water tank covers up to about 2,000 sq ft before a refill.

• 2.5 liter dust bag, replaced roughly every two months by owners
• Pro-detangling roller brush built for pet hair
• Works with Amazon Echo, Google Home, phones and tablets
• Three suction speeds and a 12.5 inch cleaning path width

The honest complaints cluster around logistics rather than performance. At 26.4 lb, moving it between floors is a two-person job, and the 16.54 inch square station wants a corner of its own. Several reviews also flag that the box arrives without printed instructions and without eufy’s own cleaning solution, and that the self-emptying cycle is loud enough to notice at night. A smaller group report mapping quirks around mirrors and floor-length windows, which usually clears after a re-run.

Compared with the eufy Omni C20, the X10 trades footprint for power. The Omni C20 does the same core jobs with a slimmer body and a lighter station; the X10 adds suction, heated drying and better obstacle handling. It also joins 2.4GHz networks only, so check your router before it arrives.

Worth weighing before you buy: both robot vacuums here refill their own water and empty their own bin, so the running cost is bags, filters, brushes and occasional eufy cleaning solution rather than any subscription.

4. SoloCam S340: Best for Solar Backyard Coverage

If you want to see the whole back of the house without running a cable, the SoloCam S340 is the reason eufy keeps coming up in solar camera conversations.

It pairs a 3K sensor with a second lens and 8x hybrid zoom, so instead of a soft wide shot you get usable detail out to about 40 ft, which is the difference between knowing someone was there and knowing who. The 360 degree pan and tilt means you mount it once on a wall and it still covers the corners. Colour night vision works to about 6 m, short of the daytime range and worth knowing before you point it at a long driveway.

The removable solar panel is the practical part. Owners single it out because you never bring the camera down to charge it, and the 10,000 mAh battery covers the gaps when the sun is not cooperating. Storage is 8GB built in, with no monthly fee attached to keeping recordings.

• Wall mount and screw-in install, roughly 7 minutes with no wiring
• AI detection and tracking for people, vehicles and motion
• Alexa voice control and the eufy app over 2.4GHz Wi-Fi
• IP-rated for outdoor use, with a 630 g body that one person can handle on a ladder

Skip it if you need to see a long driveway at night, because 6 m of colour night range will not stretch that far. The other limitation owners report is structural: a wall mount means a fixed physical position, so if you later want the camera somewhere else you are back on a ladder.

Add the Floodlight Cam E340 instead if you want a lit wall and 5GHz, and you already have power run to the mount.

The other angle is scope. The SoloCam S220 3-Pack is 2K per unit but covers three separate spots, which is usually the better trade for a first system, while this camera wins on resolution at one position.

5. SoloCam S220 3-Pack: Best for Multi-Point Coverage

Most first-time buyers are not looking for one perfect camera. They want the driveway, the side gate and the back patio covered, and the SoloCam S220 3-Pack is the box that does that in a single decision.

Each unit is a 2K solar bullet camera with an f/1.6 aperture and infrared LEDs for night vision, rated IP65 and IP67 for weather. They hold a charge on roughly three hours of sunlight, they work standalone with 8GB of built-in storage and no subscription, and they can also pair with a HomeBase 3 if you want central storage and face recognition later. That optional-hub design is what makes this pack flexible: you can start with three cameras and add the hub or more devices in a later sale.

Owners who deploy these in full sun are happy with the image quality and with never touching a camera again. The recurring complaint is exactly that sun: in shaded or frequently cloudy positions the small built-in panel struggles, and several reviews say an external panel is the fix. Pick your spots before you buy, not after.

• AI human detection with facial recognition support when a HomeBase 3 is added
• One-hole installation per unit, no cable to run
• Night colour video rather than washed-out greyscale
• Alexa voice control and the eufy app

The trade-off against the SoloCam S340 is resolution versus reach. The S340 gives you 3K and 8x zoom on a single mount; the 3-Pack gives you three angles at 2K each. If you have one problem area that needs identification detail, take the S340. If you have three blind spots, this is the box.

Good to know: the cameras run on 2.4GHz Wi-Fi, so check that your router still broadcasts it. Owners also report the app occasionally stalling on older recorded events until you refresh the view, which is annoying rather than serious.

6. Video Doorbell E340: Best for Front Door Watching

The E340 is the reason to look at eufy’s Security line before you look at its cameras, because two of the questions a doorbell answers are people and parcels, and this one watches both at once.

It carries a forward camera with a head-to-toe view plus a second lens angled down at the doorstep, so you see a visitor’s face and a package on the mat in one recording. Resolution is 2K with a 160 degree viewing angle, and the dual-light night system produces colour footage out to 16 ft, which covers a typical porch. Package and pickup alerts are the feature owners praise most, because a delivery alert is only useful if it actually fires.

Installation is flexible: a quick-release rechargeable battery, or 16-24V hardwiring if you have an existing transformer. It keeps 8GB on the device with no subscription, and it plays nicely with a mechanical chime, the eufy MiniBase Chime, HomeBase 2 and HomeBase 3, Alexa and Google Assistant. A 15 degree mount adapter is in the box for awkward doorframes.

• Two-way talk for answering a visitor from the phone
• AI detection for people, motion, audio and package events
• IP65 rated for a door that gets rained on
• A HomeBase 3 adds central, expandable recording if you want it

Owners are honest about the battery: reviews put real-world life nearer two months than the four months the listing implies, and several mention notifications and clip loading lagging enough to miss a live event. There are also reports of the unit shutting down in direct sun, which is worth weighing if your door faces south with no porch shade. Its 4.0 average is the lowest of the ten products here, and those three issues are why.

Compared with the Floodlight Cam E340, the doorbell is cheaper to install and narrower in what it sees. The floodlight covers a whole wall in the dark. If you already have a doorbell in place and want a wider second angle on the same wall, the SoloCam S340 gives you 3K and 8x zoom instead.

7. Smart Lock C220: Best for Keyless Entry

The C220 is the pick when keys are the annoyance rather than the cameras. It opens in under a second by fingerprint, over Wi-Fi, by keypad, by app, by Apple Watch, by voice or with the physical key still in the box.

Two details set it apart from most smart locks. The Wi-Fi is built in, so there is no separate bridge to find a socket for and no extra device on the network. And the fingerprint reader is self-learning, which means accuracy improves as it recognises the same finger again, so the tenth touch is usually more reliable than the first.

Power comes from eight AA batteries, which owners report lasting about eight months, and an alarm fires on unusual attempted opening. The lock is BHMA Grade 3 certified after more than 100,000 lock cycles, rated IP53, and rated to work from minus 22F to 158F. Install time is around 15 minutes with no drilling on bores under 54 mm, and two keys plus the mounting hardware are included.

• Pairs with eufy doorbells, so a delivery can be let in from the same app
• Alexa and Google Assistant support alongside app, touch and remote control
• Exterior and interior assemblies, mounting sets and a mounting plate in the box
• Aluminium construction in a modern deadbolt profile

The limitation owners name is straightforward: there is no camera on the lock, so if you want to see who is at the door, the lock only tells you that something happened. If seeing the visitor matters, pair it with the Video Doorbell E340 rather than expecting the lock to do both jobs. A second note is that a dead battery means keypad entry, so keep the physical key somewhere sensible.

One more thing to check on the way in: the lock fits bores under 54 mm, so measure the door before it arrives rather than after.

8. HomeBase 3: Best for Subscription-Free Storage

This is the product that decides whether eufy costs you anything per month, so it deserves a spot on the list even though it does not record anything by itself.

The HomeBase 3, also sold as the S380, holds 16 GB of storage out of the box and expands to 16 TB with a portable drive you add yourself. It handles up to 16 cameras and doorbells plus 34 sensors, up to 50 devices in total. BionicMind AI handles facial recognition at up to 99 percent accuracy and sends a daily security briefing to the app, and there is a 100 dB siren that can trigger automatically as a deterrent.

Encryption is AES-256-GCM and ECC-256, and cross-camera tracking lets one device follow a person across the view of another. For owners, the practical appeal is simple: local recording, no recurring fee, and no dependency on a cloud account for your video.

• Adds central recording to the SoloCam S220 3-Pack and the Video Doorbell E340
• Enable the siren or daily briefings only if you want them
• Run it on wired Ethernet, since it supports 2.4GHz Wi-Fi
• 1.5 lb hub that mounts anywhere with a shelf or a network rack

Owners do report real limits. Several reviews describe the hub struggling with continuous 24/7 recording across a large number of devices, and a laptop-style mechanical hard drive is known to overheat the base, which is why an SSD is the better expansion choice. A smaller group report connection drops, skipped clips and battery drain on paired cameras after firmware updates.

Worth knowing before you buy: you do not need this hub to start. Every camera in this list records to its own 8GB of onboard memory, so treat the HomeBase as an upgrade for capacity and face recognition rather than as part of the kit.

How it compares: the SoloCam S340 and the SoloCam S220 3-Pack both work standalone, so the hub is an upgrade for storage capacity and face recognition rather than a requirement. If you only have one camera, the 8GB onboard storage is probably enough for now.

9. Indoor Camera E30: Budget Pick for Rooms and Pets

The E30 carries a joint-highest rating in this list at 4.4 stars with the highest share of five-star ratings, and it is also the least expensive product here, so it is the easiest one to add to a system you already own.

Indoor is its job. It records 4K UHD, pans and tilts through 360 degrees with a Quick Focus Tap, and runs on-device AI that detects people, pets, audio events and crying sounds without sending the video anywhere. When it sees a person or a pet it tracks them automatically, and a built-in spotlight gives you colour night vision alongside IR. Two-way audio covers the talk-back, and pre-event recording captures a few seconds before motion starts, which is what makes the difference between catching the moment and catching the aftermath.

Unlike the outdoor cameras here, storage is a microSD card you buy yourself. That sounds like a cost until you notice the E30 keeps full functionality with no subscription, and the card is a one-off. Use a high-endurance card, as owners recommend, because a standard card is not comfortable writing 4K continuously.

• Apple HomeKit support, though HomeKit streaming is limited to 1080p
• Small 2.8 by 2.9 by 4.2 inch body, 12.48 oz, freestanding or wall mounted
• H.265 encoding at 25 frames per second, which keeps file sizes manageable
• Positioning sticker, screw pack, USB cable, adapter and wall mount in the box

The trade-off owners report most is alert sensitivity. The AI detection is thorough enough that a shadow or a curtain can trigger it, and several reviews mention notification fatigue as a result, so tune the detection zones in the app. Being corded, it also has no battery option, so the outlet has to be reachable.

If the camera is going into a relative’s home rather than your own, two-way audio and placement matter more than resolution. Tune the detection zones in the app before you hand it over.

10. Floodlight Cam E340: Best for Night Deterrence

The Floodlight Cam E340 is the one to buy when the goal is not to record a dark yard but to make sure nobody wants to be in it.

It pairs a 2K wide lens with a 3K lens and 8x hybrid zoom, giving telephoto detail out to about 50 ft, and the 2,000-lumen light has adjustable brightness with a 95 dB audible alarm on top. AI detection covers humans, vehicles and pets, and auto-patrol schedules let it move through its coverage on its own, with cross-camera tracking when a HomeBase S380 is part of the setup.

Two technical details put it ahead of the battery cameras here. It is dual-band Wi-Fi 6, so it uses both 2.4GHz and 5GHz and holds a steadier link at distance. And it records 24/7 continuously to a microSD card up to 128 GB or to the HomeBase S380, with no subscription on either path.

• 360 degree coverage from an ultra-wide lens plus pan and tilt, 355 degree viewing angle
• IP65 weatherproof, mounts to a wall, junction box or ceiling
• HomeBase 3, Alexa and Google Assistant compatibility
• Uses for back yard, front door and driveway security

The trade-off is installation. This is a wired unit, so power has to reach the mount, and at 1,380 g in a 12.6 inch housing it is a two-person job high on a wall. Owners also note that resolution caps at 2K when AI tracking or dual view is switched on, so decide which you care about more before mounting it.

Two neighbours cover similar ground differently. For a driveway or side entrance with no power run, the SoloCam S340 goes up faster on solar; for a backyard where wiring is awkward but you want light after dark, this one is worth the install. The E340 Video Doorbell handles the same wall from a lower angle and only the door area.

How to Choose Eufy Products During Prime Big Deal Days

Solar, wired or battery cameras

Start with how much you want to install. Battery and solar cameras go up in minutes with one hole and no cable, which is why the SoloCam S340 and the SoloCam S220 3-Pack lead this list for yards and driveways. A wired camera such as the Floodlight Cam E340 is the better answer when you want continuous 24/7 recording, a bright light and a stable 5GHz link, and you have a power run to the mounting spot.

Do you need a HomeBase at all?

No, not to start. Every camera and doorbell in this list keeps 8GB onboard, so a single SoloCam or a Video Doorbell E340 records without a hub and without a monthly fee. Add the HomeBase 3 when you want more capacity than 8GB, facial recognition across devices, a 100 dB siren, or a single place to review everything. Choose an SSD for expansion rather than a laptop-style drive, which owners report can overheat the base.

Indoor monitoring and two-way audio

For rooms, nurseries and pets, the Indoor Camera E30 is the one with 4K, 360 degree pan and tilt, on-device AI for people, pets, audio and crying sounds, and two-way talk. If the camera is going into a relative’s home or somewhere you are not standing next to, our notes on Eufy cameras for elderly go deeper on placement and on making two-way audio actually usable for the person in the house.

Dock size and runtime for robot vacuums

Measure before you buy either vacuum. The eufy Omni C20 has a 132 minute runtime and a 3.35 inch body, while the eufy X10 Pro Omni has more suction and heated mop drying but needs more floor space around a 16.54 inch station and weighs 26.4 lb to move. If furniture clearance is tight, the eufy 11S MAX at 2.85 inches tall is the one that fits under everything, and it needs nothing but a floor for its small charging dock.

Keyless entry that fits your door

The Smart Lock C220 fits bores under 54 mm and installs without drilling in about 15 minutes on most standard deadbolts. Check your bore size and whether your door is a standard deadbolt before ordering, and note that the lock has no camera, so it reports entry events rather than showing you who is there.

How to Shop Eufy Security and Cleaning Deals During the Sale

On a eufy listing, the model code is the part that tells you whether you are looking at the current generation. SoloCam S340 and S220 are solar, the E30 and the Floodlight Cam E340 are wired, and the HomeBase S380 is the hub.

Check the pack count on multi-camera listings, because a 3-pack and a single unit can share a product page. Look at what is in the box, since cleaning solution and paper instructions are missing from the X10 Pro Omni and the storage drive is not included with the HomeBase 3. Note whether the seller is Amazon or a third-party merchant, and whether the offer is new or a renewed unit. Most offers during this event need a Prime membership, and prices move through the two days.

• Match the power type to your install: solar and battery for no wiring, wired for 24/7 recording and brighter output
• Confirm 2.4GHz or dual-band Wi-Fi against your router before ordering
• Decide on a HomeBase based on storage capacity and face recognition, not as a default
• For vacuums, measure low furniture clearance and the floor space the dock needs
• For cameras, budget for the microSD card or expansion drive separately
• Check the pack count and the model code on the listing before you add anything to a cart
