Roborock S7 Max Ultra robot vacuum & mop with auto-empty, auto mop washing, auto mop drying.
This is the Max Ultra Model. The comparison to MaxV Ultra are:
Slightly higher 5500Pa suction (5100Pa for MaxV) although it is unlikely to make any practical difference.
Mop drying function included rather than an add-on module in MaxV
350ml built-in dust bin a little bit less than 400ml in MaxV
bought this when it was last at this price. Happy with the machine. The only criticism is that it can't be plumbed in.
