Fit verdicts by condition for each robot
Condition Qrevo Edge 3 Pro Saros 20 Flow Complete
Home size
Under 1,500 sqft GoodIn independent lab testing, it took 18 minutes to clean a 204 sq ft area on the normal cycle, so small homes finish quickly. GoodHandles compact homes easily; suction and LiDAR mapping comfortably cover a small floor plan, though the dock automation is more than most small spaces need.
1,500 – 3,000 GoodStuff ran combined mop and vacuum cycles of nearly 90 minutes without the battery running out mid-clean. Good36,000 Pa suction and retained multi-room LiDAR maps suit mid-to-large floor plans across several rooms.
Over 3,000they differ DependsRoborock claims about 3,770 sq ft per charge; no independent run across a home this size has been published. GoodMulti-level maps and a self-servicing dock handle large multi-floor homes with minimal owner intervention.
Primary floors
Hard floors GoodIndependent lab testing recorded 94% flour pickup on hard floor, and another reviewer saw an upturned flour bag cleared. GoodRoller mop refreshed with clean water and 36,000 Pa suction target sealed hard floors, the surface it is built for.
Low / medium pile GoodOne reviewer found fine dust, crumbs and rice lifted from carpet, with pads raised so rugs stayed dry. GoodCarpet detection lifts the mop 15 mm and raises suction, so low-pile rugs are cleaned without wetting.
High pile / shag DependsRated for pile up to 1.18 in; independent lab testing measured 57% flour pickup on carpet and missed a sock there. DependsMop lifts only 15 mm and the roller is built for hard and low-pile; suction retention on deep pile is not independently tested for this SKU.

A robot being poor for a condition is a fact about fit, not a fault. “Depends” means the record names a limit worth reading, not that the answer is unknown.
