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
  • Fully retractable LiDAR in an 80 mm body
  • AdaptiLift chassis: 20 mm lift for 3 cm carpet, 4 cm double steps, escapes chair legs
  • 12 N spinning mops that stay in the dock for carpet; washed at 100 °C, dried at 55 °C
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
  • Runtime, noise, bin and tank not published in a usable form
  • Tank refilling not claimed for the dock
  • Not in Roborock's American shop when read
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 rugs, sills and chair legs that stop lesser robots
  • Buyers who want Saros clearance and sensing without the Saros badge
