Roomba vs Eufy robot vacuums

Mops: Roomba's covered roller against Eufy's HydroJet rollers

The Roomba Max 705 Combo uses a PowerSpin roller mop at 200 RPM that cleans itself as it goes, extends for edges, uses heated mopping and slides a protective cover over itself so carpets stay dry. The cheaper Roomba 505 Combo uses DualClean pads that extend at the edge and lift automatically when it senses carpet.

Eufy's Omni S1 Pro has a roller mop of about 11.4 inches that the HydroJet system refreshes with clean water at 170 RPM, pressing down with 1 kg. The C28 Omni has a 27 cm roller with the same 1 kg of pressure and real-time self-cleaning. Both brands therefore offer a self-rinsing roller near the top of the range; our roller against rotating mop comparison explains why that design suits large hard floors.

Docks and emptying intervals

Both Roomba AutoWash Docks list 75 days of auto-emptying into a bag. The Max 705 Combo dock also gives about eight weeks of heated mopping and roller washing based on one mopping run a week, heated roller drying, automatic solution dispensing and a self-clean cycle. The 505 Combo dock offers about four weeks of mopping and pad washing and heated pad drying.

Eufy's Omni S1 Pro station lists ten jobs: emptying, washing, drying, refilling, waste-water collection and detergent dispensing among them, with a sealed dust bag and a touch screen. The C28 Omni station empties, washes, refills, dries with hot air and collects dirty water. Whichever you choose, the clean and dirty water tanks still need regular attention; see how to empty a robot vacuum.

Navigation and obstacle avoidance

Roomba's strongest point is object recognition. Both Roomba models combine ClearView Pro lidar with PrecisionVision AI, which the listings say recognises cords, socks and even pet waste and steers around them. They also identify wet and dry messes ahead and repeat passes on them.

Eufy's S1 Pro uses 3D MatrixEye, which combines binocular infrared imaging with an RGB camera to build 3D models of objects. The C28 uses iPath 2.0 navigation that the listing says works in low light and under furniture. If you share your home with a puppy or cables on the floor, compare the avoidance claims carefully; our guide to robots with obstacle avoidance goes further.

Spec sheet from the listings

All figures come from the Amazon UK listings. Not stated means the listing does not give it.

Buying a Roomba in the UK

Some older Roomba listings on Amazon UK are imported stock with a North American plug and no UK warranty. Before you buy, check that the listing says UK plug and that the seller offers UK support. The current Combo models above are listed for the UK market.

iRobot quotes suction as a multiple of its old 600 series rather than in pascals, so you cannot compare it directly with Eufy's 15,000 Pa figure. Our suction explainer explains why that is less important than it looks.

Note:Use the plug and charger supplied for the UK. Never run a robot or dock through a travel adaptor or voltage converter.

Do Roomba and Eufy use the same bags? No. Each dock takes its own bag shape, so buy bags for your exact dock model.

Which app is easier? Both the Roomba Home app and eufy Clean are straightforward for rooms, zones and schedules. Roomba's app adds dirt prediction that picks rooms automatically.

How do I find which Roomba I have? The model number is on a label under the robot. Our page on what Roomba you have shows where to look.
