Higher rated

Narwal Freo Z10

#5 in Self-cleaning dock4.4Full review

A lot of robot for about $500: strong carpet cleaning, long range and a hot-water mop-washing dock. Good for privacy-minded buyers who don’t need camera-based avoidance.

#55 in Self-cleaning dock3.4Full review

Suits large, mostly hard-floor homes that want a self-washing mop dock from a familiar brand; weak carpet and pet hair results make it a poor fit for rugs and pets.
