A carpet cleaning apparatus comprises a housing and wheels rotatably connected to the housing for moving the housing over a carpet. A brushroll, supported by the housing, is rotatable about a first axis. A pulley, supported by the housing, is rotatable about a second axis parallel to the first axis. A drive wheel, supported by the housing, is rotatable about a third axis parallel to the first axis. A belt has inner and outer surfaces. The inner surface extends about and engages the brushroll and the pulley. The outer surface engages the drive wheel. The belt is pulled by the pulley downward against the drive wheel for the drive wheel to drive the brushroll through the belt. |
