Dual-roller vs single-roller vacuum: Dual-roller wins for pet hair

Dual-roller has a separate brush roll and pickup roller, so it handles shedding dogs and cats without tangling. Single-roller tries to do both jobs at once and clogs fast with animal hair. If you have a low-shedder or don’t mind maintenance, single-roller can work, but for daily shedders like labs or pugs, dual-roller saves frustration.
