At a glance
Leads on	Obstacle Avoidance Automation	Cleaning Navigation Mopping Value
Pros	Steam mopping at 180 °C from the boiler, with a fresh-water wipe after it and, by a later update, automatic re-mopping of dried-on stains 270 mm roller at 18 N and 300 rpm that extends 8 cm, lifts 15 mm and seals itself on carpet 40,000 Pa behind a TÜV-certified anti-tangle DuoBrush, with brushes that lift too	Solid-state 3D sensing with no turret: 80 mm tall and still maps in the dark Leaves the mop on the dock for carpet and lifts the chassis over 30 mm of pile 36,000 Pa with a fully anti-tangle brush and an extending side brush
Cons	No runtime, charging time, noise figure or warranty term published Steam and the extended roller cannot be used at the same time; room-mode steam and the automatic re-mop wait for an update 6.12 kg, the heaviest Dreame robot vacuum we list	Roborock publishes neither the dustbin nor the water tank capacity One year of warranty No plumbed drain: the dirty-water tank is still emptied by hand
Best for	Kitchens with greasy or dried-on stains, where steam does what pads cannot Homes with sills, rugs and pets, where the legs, the lift and the pet features all count	Homes with a mix of hard floors and carpet Low furniture that a LiDAR turret cannot fit under
