Not sold on them, We have the Roborock Q S,  they don't vacuum close to the baseboards/edges, that little "edge brush" is a joke.  They don't have much suction power.
Not bad for daily touchup, but still need a good vacuum to get the house really clean.
After mopping the house twice, the "dirty" water in the tank was still nearly clear. The dirt bin is also basically clean.
Nobody cleans like my wife.
