In general, the purchase is satisfied. It performs its function, in my opinion, at 4.5. Pros below: Intuitively clear both the vacuum cleaner, and the software (Roborock). The camera, and specifically the ability to view remotely, is a real plus. Dust-garbage collects pretty decently. Cons below: Doesn't push through curtains. Wet cleaning goes in stripes, but perhaps this is a problem in the rag itself. Sometimes it gets tangled up in wires. Obstacles go around with a decent margin, so there is a fairly large uncleaned area around the obstacle.
