Numatic HAIROBRUSH - High Performance Floor Tool for HVR200M-22 The unique Numatic dual purpose HairoBrush has been designed so that it can give excellent pick up performance both on the floor and equally as a hand brush for use on upholstery and stairs. The new pet owners best friend. This unit gives a 100% improvement on standard upholstery brushes. The unit is 195mm wide (approx seven and a half inches). Underneath the unit there is a trap door to clear the debris from the turbo wheel to ensure 100% spin speed on the brush. The brush has a blade slot to run a knife down to cut any hair etc that has become wrapped around the brush. Suitable for all 32mm diameter pipes. This would include all Henry Hetty James Charles George machines. If a machine starts its model number with a 3 or 2 (nrv200 hvr370) then this will be a 32mm machine.
