What to look for

Lidar mapping cleans in neat lines and supports no-go zones; a self-emptying base saves effort.

Models worth comparing

Budget

eufy Robot Vacuum 3-in-1 E20

Flats and smaller homes short on storage that want one machine to work as a robot, a stick and a handheld vacuum.

The vacuum module lifts out to become a handheld or cordless stick
Laser navigation that maps and remembers up to five floors
Self-emptying station with a bag eufy says can last up to 75 days

Watch out for: It vacuums only, with no mopping, and Expert Reviews found it capable but not the best at any one job.

Suction (claimed): Up to 30,000Pa
Navigation: LiDAR (triple-laser)
Self-empty base: Yes, up to 75 days
Mopping: No
Extras: Converts to handheld and stick vacuum

Mid-range

eufy Omni E25

Households wanting a capable vacuum-and-mop robot with an all-in-one dock without paying flagship prices.

HydroJet roller mop is rinsed as it turns and pressed down with 1.5kg of force
20,000Pa claimed suction with DuoSpiral brushes designed to stop hair tangling
Dock washes and warm-air dries the mop and empties dust into a 3L bag

Watch out for: The dock is large and bulky, and the glossy black plastic on dock and robot shows dust easily.

Suction (claimed): 20,000Pa
Navigation: LiDAR with AI-assisted front camera
Self-empty base: Yes, 3L bag, up to 75 days
Mopping: Roller mop, 1.5kg pressure, heated-air drying

Homes with low furniture, pets and raised thresholds that want a robot to vacuum, mop and look after itself.

36,000Pa claimed suction and a climbing chassis for double thresholds up to 4.5cm + 4.3cm
Structured light and an RGB camera to recognise over 300 object types; 100°C mop washing

Watch out for: Expert Reviews found its cleaning a little inconsistent and the app confusing at times.

Navigation: Retractable LiDAR plus structured light and RGB camera
Self-empty base: Yes, up to 65 days

Pro

Roborock Saros 20

Buyers who want Roborock's flagship, with top-tier obstacle avoidance and the most hands-off dock, and are happy to pay for it.

StarSight 2.0 3D sensing instead of a LiDAR turret, keeping the body 7.98cm tall
36,000Pa claimed suction with a dual anti-tangle system
Dock adds 100°C mop washing, warm-air drying, detergent dosing and tank refilling

Watch out for: It is very expensive, and much of its headline spec, such as suction and threshold climbing, is shared with the cheaper Saros 20 Neo.

Suction (claimed): 36,000Pa
Navigation: StarSight 2.0 3D sensing (no LiDAR turret)
Self-empty base: Yes, up to 65 days
Mopping: Liftable mops, 100°C washing, 55°C air drying
Thresholds: Double thresholds up to 4.5cm + 4.3cm
