Abstract
A surface-cleaning apparatus is disclosed. The apparatus includes one or more brushes rotatably driven by a motor in order to collect debris without suction being applied by the apparatus. The apparatus is capable of detecting a resistance or friction level of the surface to be cleaned, and can automatically adjust the rotational speed of the motor, and thereby the rotational speed(s) of the brush(es), based on changes in the surface. Additionally, the apparatus is capable of detecting jamming or locking of a brush and turning off the motor in response to detecting such jamming or locking.
