The roomba isn't too successful with the wife's hair or our V's fur...needs constant maintenance - but powerful and stupid.
The roborock does a very good job, with minimal/no maintenance, intelligent, although the dust bin is a bit small. The mop (only wipe) is nice, but would like to have had a bit of scrubbing action for paw prints. The video is nice to harass the dog with a 'Pacman' game while at work.
Our V only sheds for like 2 weeks a year, but for those 2 weeks, the roborock cannot keep up.
Off topic, I'm more interested in how your Vizsla does with your cats? I've always wanted cats in CH, but was never allowed/able to care for them. Got the dog instead, but still would like to have some cats - just unsure how she will react when the hunt instinct warrants a swat/scratch.
