Shark PowerDetect NeverTouch Pro

#87 in Self-cleaning dock3.9Full review

Fine for smaller homes with mostly hard floors and carpet that needs a deep clean, but the newer ThermaCharged adds heated washing and better pet hair pickup for less money at Shark.

#103 in Self-cleaning dock3.2Full 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.
