The models in detail
This page is for owners of big or multi-story houses who want a robot vacuum that can cover a lot of floor and look after itself between runs. We compared six models from their Amazon.com product listings, checked on October 10, 2026. Nothing here was run in a real house: runtimes and capacities are the manufacturers' claims, and we say clearly when a listing leaves the battery or runtime out.
1 · Our pick
eufy Omni C28
Robot vacuum4,3/5 from 59602 Amazon customer ratings (as of October 10, 2026)
In a large house, the robot you pick has to run for weeks without you stepping in, and the Omni C28 station does more of that than any other here. It empties debris into a 3 L bag for up to 75 days, washes the roller mop, hot-air dries it at 50°C, refills water automatically and collects wastewater. Camera-free LiDAR maps the floor plan and avoids obstacles of 3 x 3 x 3 cm and larger, and suction is listed at 15,000 Pa. The weak point for this page is clear: the listing gives no runtime and no battery capacity, only a long-lasting battery. If you need to know how much floor one charge covers, the Omni E25 states 125 min, and the Shark AI Ultra states up to 90 minutes with recharge and resume. The listing also does not say how many floor maps the C28 stores.
Pros, cons and specs
Pros
- The 28 cm HydroJet roller has 24 water ports and spins at 270 RPM, with a scraper sending dirty water to a separate tank.
- DuoSpiral brush is rated for hair up to 30 cm (11.8 in) without wrapping, per eufy's own cleaning tests.
- The station empties into a 3 L bag, washes the mop and hot-air dries it at 50°C for up to 75 days of hands-off use.
- Camera-free LiDAR navigation avoids obstacles of 3 x 3 x 3 cm and larger.
Cons
- Runtime and battery capacity are not stated (only a "long-lasting battery").
- Without a camera, objects smaller than 3 x 3 x 3 cm (cables, socks) may not be avoided.
- Dust bags are a consumable to replace.
Best for: Multi-pet homes with hard floors and short carpets that want a self-cleaning roller mop without a camera.
Skip it if you need published runtime figures or have lots of small clutter on the floor.

2 · Multi-floor houses
eufy Omni E25
Robot vacuum4,4/5 from 54090 Amazon customer ratings (as of October 10, 2026)
The Omni E25 is the model on this page that answers the large-home question with figures. It claims 125 min of runtime in standard vacuum and mop mode and stores up to 5 floor maps, the most here, which matters if you carry the robot between stories. Suction is listed at 20,000 Pa, above the Omni C28's 15,000 Pa. The station matches the C28's: it empties into a 3 L bag lasting about 75 days, washes the 11.4 in HydroJet roller, hot-air dries at 50°C and refills water. It climbs thresholds of 21 mm, useful for doorways across many rooms, and lifts the mop 10.8 mm, though thicker rugs may still need no-go zones. Battery capacity is not given. The robot does not support 5 GHz Wi-Fi, so a big home with a weak 2.4 GHz signal at the far end may need a check first. Its 54,090 reviews appear to be shared with other eufy models.
Pros, cons and specs
Pros
- The HydroJet roller mop is rinsed with clean water 2 times per second, with 1.5 kg of downward pressure.
- 20,000 Pa suction plus DuoSpiral brushes that eufy says cut hair tangling by 53% versus previous models.
- The station empties into a 3 L bag lasting about 75 days, washes the roller, hot-air dries at 50°C and refills water.
- 125 min runtime in standard vacuum + mop mode and up to 5 saved floor maps.
Cons
- The robot does not support 5 GHz Wi-Fi, and it is a 110V US model.
- Dust bags are a consumable to replace.
- Mop lift is 10.8 mm, so thicker rugs may still need no-go zones.
Best for: Larger multi-floor homes with pets that want a roller-mop robot with a full-service station.
Skip it if your home network is 5 GHz only or you have many high-pile rugs.
Other specs
- Suction20,000 Pa
- MoppingHydroJet roller mop (11.4 in), refreshed 2 times per second

3 · Big homes, light mopping
iRobot Roomba 105 Combo + AutoEmpty
Robot vacuum4,4/5 from 49377 Amazon customer ratings (as of October 10, 2026)
The Roomba 105 Combo + AutoEmpty uses ClearView LiDAR to map the house, which lets it clean room by room instead of wandering, a must in a big floor plan. Its AutoEmpty dock holds up to 75 days of debris in a bag, the same interval as the eufy stations. The app sets vac only, mop only or combo modes and adjusts passes and suction, so you can run quick vacuum-only sweeps across many rooms and save mopping for the kitchen. For a large home, the gaps are significant: no runtime, no battery capacity and no Pa suction figure, only a claim of 70X more power-lifting suction. The pad does not lift, and the dock does not wash it, so mopping a lot of floor means rinsing pads often. It is rated 4.4 from 49,377 reviews.
Pros, cons and specs
Pros
- Empties into a bagged AutoEmpty dock for up to 75 days; the bag traps 99% of allergens as small as 0.7 microns, according to the listing.
- ClearView LiDAR maps the home, and the robot detects and avoids carpets while mopping.
- Vac only, mop only or combo modes, with adjustable passes, suction and mopping solution in the app.
- SmartScrub adds 2x deeper scrubbing; the box includes 1 extra mop pad.
Cons
- Dock bags are a consumable to replace.
- The pad does not lift and the dock does not wash it.
- Suction is given only as 70X more power-lifting suction, with no Pa figure or runtime.
Best for: Budget buyers who want LiDAR mapping, light mopping and a self-emptying dock in one box.
Skip it if you want a mop that lifts over rugs, a self-washing station or a bagless dock.
Other specs
- MoppingMicrofiber mop pad with micro-pump
- Bag / binBagged dock
- Connectivity2.4 GHz Wi-Fi, Roomba Home app, voice assistants
4 · Large vacuum-only coverage
Shark AI Ultra AV2511AE
Robot vacuum4/5 from 41687 Amazon customer ratings (as of October 10, 2026)
Recharge and resume is the feature that makes a robot workable in a large home, and the Shark AI Ultra AV2511AE pairs it with a stated runtime: up to 90 minutes, after which it recharges and resumes where it left off. That is less than the Omni E25's 125 min, but it is one of the few published figures on this page. Its 360° LiDAR maps the home, detects objects and works in the dark, and Matrix Clean runs grid passes. The bagless base holds up to 60 days of debris with no bags to buy. It is vacuum only, and the listing gives no suction figure in Pa or battery capacity. Part of the product page describes a 2-in-1 vacuum and mop, which does not apply to this model. Only 1 side brush and 1 filter come in the box. Its 41,687 reviews look pooled with another Shark.
Pros, cons and specs
Pros
- The bagless self-empty base holds up to 60 days of debris with no bags to buy, according to the listing.
- 360° LiDAR maps the home, detects objects and works in the dark.
- Matrix Clean takes multiple passes in a grid pattern, and the self-cleaning brushroll is meant to prevent hair wrap.
- Up to 90 minutes of runtime, then it recharges and resumes where it left off.
Cons
- Suction power in Pa is not given.
- Vacuum only: no mopping on this model.
- Only 1 side brush and 1 filter come in the box.
Best for: Pet owners with mixed carpet and hard floors who want a LiDAR vacuum with a bagless self-empty base.
Skip it if you also want mopping or need a published suction figure to compare models.
Other specs
- MoppingNo mopping
- Anti-tangleSelf-cleaning brushroll
- ConnectivitySharkClean app, Alexa, Google Assistant
5 · Bagless vacuum-mop combo
Shark Matrix Plus AV2610WA
Robot vacuum4/5 from 36550 Amazon customer ratings (as of October 10, 2026)
The Shark Matrix Plus AV2610WA covers a lot of ground in one trip by vacuuming and sonic-mopping in the same pass, scrubbing 100x per minute according to the listing. Its XL bagless base holds up to 60 days of debris with HEPA filtration rated for 99.97% of dust down to 0.3 microns. 360° LiDAR with object detection maps the home, and Matrix Clean grid passes target carpets, edges and corners. For a large house, the listing leaves out the two figures you most want: runtime and suction in Pa. It also does not mention recharge and resume, unlike the Shark AI Ultra and the Roomba 105 Vac. The base does not wash the mop pads, and in a big home you will swap and wash the 2 included microfiber pads often. It ships with a 1-year limited warranty.
Pros, cons and specs
Pros
- Vacuums and sonic-mops in one pass, scrubbing hard floors 100x per minute, according to the listing.
- The XL bagless base holds up to 60 days of debris and uses HEPA filtration rated for 99.97% of dust down to 0.3 microns.
- Matrix Clean grid passes and CleanEdge Detect air blasts target carpets, edges and corners.
- Ships with 2 reusable microfiber pads, a 12oz. starter cleaning solution and a 1-year limited warranty.
Cons
- Suction power in Pa and runtime are not given.
- The base does not wash or dry the mop pads; pads are swapped and washed by hand.
- Cleaning gains are quoted against older Shark models, not against competitors.
Best for: Households with carpets and hard floors that want a LiDAR vacuum-mop with a bagless self-empty base.
Skip it if you want a base that also washes and dries the mop, or you need runtime and suction figures.
Other specs
- MoppingSonic mopping pad (scrubs 100x per minute)
- Anti-tangleSelf-cleaning brushroll
- ConnectivitySharkClean app
6 · Secondary floor robot
iRobot Roomba 105 Vac
Robot vacuum4,2/5 from 31642 Amazon customer ratings (as of October 10, 2026)
The Roomba 105 Vac has ClearView LiDAR mapping and recharges and resumes where it left off, two useful traits for a big floor plan. Keep-out zones and schedules in the Roomba Home app let you split a large home into regular runs. Its limit for this page is the bin: it has a charging dock only, so you empty debris by hand, and in a large house that can mean after nearly every run. The Omni C28, Omni E25 and both Sharks all empty themselves. iRobot gives no runtime, no battery capacity and no Pa figure, so you cannot tell how many rooms one charge covers. That makes it a better fit as a second robot for one floor than as the only robot in a big house. It works only on a 2.4 GHz network, and it is rated 4.2 from 31,642 reviews.
Pros, cons and specs
Pros
- ClearView LiDAR maps the home and steers around obstacles, with cliff sensors for stairs, according to the listing.
- 3-Stage Cleaning with a Multi-Surface brush and an Edge-Sweeping brush, claimed at 70X more suction than Roomba 600 series robots.
- Recharges on its own and resumes where it left off.
- Spot cleaning for up to 5 minutes, keep-out zones and schedules in the Roomba Home app.
Cons
- No self-empty base: you empty the bin by hand.
- Vacuum only, with no Pa figure or runtime given.
- Works only on a 2.4 GHz network.
Best for: Budget buyers who want a LiDAR-mapping Roomba without paying for a dock.
Skip it if you want a self-emptying base or mopping.
Other specs
- MoppingNone (vacuum only)
- Connectivity2.4 GHz Wi-Fi, Roomba Home app, Alexa, Siri, Google Assistant
How to choose a robot vacuum for a large home
Stated runtime
Favor a model that publishes its runtime, because in a big house that number decides how much floor one charge covers. On this page, the Omni E25 claims 125 min in standard vacuum and mop mode, and the Shark AI Ultra claims up to 90 minutes. The Omni C28, both Roomba 105 models and the Shark Matrix Plus give no runtime. Treat every figure as the manufacturer's claim, since mopping, suction level and carpet all affect real coverage.
Recharge and resume
Make sure the robot can recharge mid-job and pick up where it stopped, or large homes will be left half done. The Shark AI Ultra and the Roomba 105 Vac both state this feature on their listings. The other listings on this page do not mention it explicitly, so check the product page or the app description before you count on it for a whole-house clean in one session.
Multi-floor maps
If your home has several stories, pick a robot that saves more than one map. The Omni E25 stores up to 5 floor maps. The Omni C28, Roomba and Shark listings here describe LiDAR mapping but do not give a number of saved maps. Without multiple maps, you may have to remap each time you carry the robot upstairs.
Station capacity
A larger bin interval means fewer trips to the dock in a home with lots of floor. The Omni C28, the Omni E25 and the Roomba 105 Combo dock all quote up to about 75 days with a bag. Both Shark bases are bagless and quote up to 60 days. The Roomba 105 Vac has no self-empty base. Those intervals are the makers' own estimates and will shrink in a bigger, busier house.
Mop care across many rooms
If you want mopping in a large home, a station that washes and dries the mop is close to essential. The Omni C28 and the Omni E25 both wash the roller and hot-air dry it at 50°C, and both refill water. The Roomba 105 Combo and the Shark Matrix Plus leave the pads to you, which adds up fast across many rooms. The Shark AI Ultra and the Roomba 105 Vac do not mop.
Wi-Fi reach
Check your Wi-Fi coverage before buying, because most of these robots connect only to a 2.4 GHz network. The Omni E25 does not support 5 GHz, and both Roomba 105 listings say they work only on 2.4 GHz. In a large house, the far rooms may have a weak signal, which can affect app control and scheduled runs. A mesh system that broadcasts 2.4 GHz throughout the home avoids that.
Skip it if…
- you want a guaranteed number of rooms per charge, since every runtime here is a claim and four of the six listings give none.
- your Wi-Fi is 5 GHz only, because the Omni E25 does not support it and both Roomba 105 listings require 2.4 GHz.
- you plan to mop a big house without a washing station, which means hand-washing pads on the Roomba 105 Combo or the Shark Matrix Plus.
- you want the robot to empty itself on every floor, as the Roomba 105 Vac comes with a charging dock only.
FAQ
What is the best robot vacuum for large homes?
The eufy Omni C28 is our pick for large homes because its station empties, refills, washes and dries for up to 75 days with little input from you. Its listing gives no runtime, though. If you need a stated figure, the eufy Omni E25 claims 125 min and stores up to 5 floor maps.
How long does a robot vacuum battery last in a big house?
It depends on the model and settings, and only two listings here give a figure. The Omni E25 claims 125 min in standard vacuum and mop mode, and the Shark AI Ultra claims up to 90 minutes before it recharges and resumes. The other four models on this page do not state a runtime.
Can one robot vacuum clean a whole multi-story house?
Yes, if it stores several maps and you carry it between floors. The Omni E25 saves up to 5 floor maps. The dock stays on one floor, though, so the robot returns there to empty and charge. Many owners with large homes run a second robot, such as a Roomba 105 Vac, on another floor.
Do large homes need a self-emptying robovac?
In most cases, yes, since more floor means a fuller bin after each run. On this page the eufy stations and the Roomba 105 Combo dock quote up to 75 days with a bag, and both Shark bases quote up to 60 days bagless. The Roomba 105 Vac has no self-empty base, so you empty it by hand.
Is the eufy Omni E25 better than the Omni C28 for large homes?
On published figures, the Omni E25 is stronger for large homes. It claims 125 min of runtime, 20,000 Pa of suction, 21 mm threshold climbing and up to 5 floor maps. The Omni C28 lists 15,000 Pa and gives no runtime, but it shares the same full-service station design with hot-air drying.
What is recharge and resume on a robot vacuum?
Recharge and resume means the robot returns to its dock when the battery runs low, charges, then goes back to finish where it stopped. It is the feature that lets a robot cover more floor than one charge allows. On this page, the Shark AI Ultra and the Roomba 105 Vac state it on their listings.
