A:Answer I just checked the brushes and I don't see ANY hair stuck around the rollers at all, and our household has shoulder length hair, too. Roombas in general do require regular maintenance cleaning however, but it hasn't prompted to do it yet after 1.5 months of daily vacuuming. Maintenance cleaning involves washing the dust bin with water, checking the rollers, wheels and spin brushes to clear any hair/dust build-up.
