You have a good point. I've heard (and maybe this was true only for older models) that the vacuuming power was weak and ineffective, corners were left uncleaned, and the job was spotty. But I can see this as a between vacuuming filler for major debris, not a thorough cleaning, which requires human attention.
I have several cats, and would be interested in seeing how they would react. :)
Cats like Roombas.
And, I’m hoping soon we can get a cat. So we’ll see if I can combine the 2!
Yeah, regular weekly or more maintenance. More than that you start needing a real manual vacuuming.
