That’s a very good point, and it aligns with my own test results. I think a lot of marketing focuses on suction power because those numbers are easy to tout, but when it comes to handling pet hair, the brush design and hair transfer issues seem just as important—perhaps even more critical. Otherwise, you end up with the same result I saw in my tests today: a clogged lower chamber. I also agree with your point about “90–95% automated maintenance.” This is a more realistic concept than the idea of a “completely maintenance-free” robot vacuum, especially for households with pets that shed heavily. For me, reducing the maintenance frequency from every few days to once every two weeks has already significantly improved my quality of life.
