Overview
A pet owner or busy household gets a robot that extends its side brush and mop toward corners and under furniture, then returns to an all-in-one dock that empties and cleans itself. The mop lifts over carpet, and obstacle avoidance and app control are listed.
High suction, long run time in Quiet Mode and a dock that handles upkeep make it a low-maintenance machine. The optional detergent dispenser is sold separately, and dock capacity, bin size and noise are not described.
Who it's for
Pet owners who want corners and edges handled and carpets protected from the mop. Voice assistants cover Alexa, Siri and Google Home. Shoppers who need published dock and noise data should look elsewhere.
