Roborock Q Revo vs Roomba j9+: Roborock wins for pet owners with hard floors

The Q Revo is the better pick for pet hair and mopping, and it costs less. The mopping difference is huge — the Q Revo uses two spinning pads that scrub the floor, then washes and dries itself in the Roborock dock, while the [Roomba j](https://www.amazon.com/s?k=Roomba+j&tag=wehavethat-20)ust drags a vibrating cloth across the tile. For pet hair, both do a solid job, but the Q Revo’s rubber brush tangles less.
