Cons
Sort
-
Streaking and residue were a weak point in one muddy-pawprint test where the robot smeared mud on a pass.
-
Support and reliability had a notable caveat when support could not solve a repeated navigation problem away from the dock.
-
Floor drying or wetness was a weakness in one mopping review, especially on the wettest settings.
-
Storage footprint was the biggest design drawback because the dock is tall, bulky, and visually intrusive.
-
Small-space suitability was limited by the dock needing open space and causing confusion in a narrow kitchen setup.
-
Surface safety with attachments was mixed because raised mop pads could still skim carpet unless settings were adjusted.
-
Dock noise was mixed: one unit squeaked during mop washing, while other reviewers found emptying brief or not too loud.
-
Reviewers liked the robot itself but repeatedly criticized the dock’s visual bulk, producing a split design assessment.
