Fit verdicts by condition for each robot
Condition Dreame X50 Ultra Qrevo Edge 3 Pro
Home size
Under 1,500 sqft Good180-minute runtime covers typical small homes; suits single-pass cleaning but limits zone flexibility. GoodIn independent lab testing, it took 18 minutes to clean a 204 sq ft area on the normal cycle, so small homes finish quickly.
1,500 – 3,000 GoodOptimal range for this unit. Runtime and tank capacity support typical 1,500–3,000 sqft multi-floor homes. GoodStuff ran combined mop and vacuum cycles of nearly 90 minutes without the battery running out mid-clean.
Over 3,000 DependsRequires zone-based cleaning or two separate sessions to cover large homes without dock return mid-cycle. DependsRoborock claims about 3,770 sq ft per charge; no independent run across a home this size has been published.
Primary floors
Hard floors GoodVersaLift and ProLeap legs optimized for tile, sealed wood, and hard floors. Hot-water mop cleaning ideal for this category. GoodIndependent lab testing recorded 94% flour pickup on hard floor, and another reviewer saw an upturned flour bag cleared.
Low / medium pile GoodSuction tuning and brush design handle low-pile carpet well. Dual-tank mop system adds versatility. GoodOne reviewer found fine dust, crumbs and rice lifted from carpet, with pads raised so rugs stayed dry.
High pile / shagthey differ PoorOwner reports document suction loss on shag and high-pile carpets. Brush cannot achieve necessary contact pressure. DependsRated for pile up to 1.18 in; independent lab testing measured 57% flour pickup on carpet and missed a sock there.

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.
