Abstract
The vacuum nozzles in a rotary surface cleaning appliance are skewed with respect to the path of travel of the nozzles to enable the nozzles to glide smoothly over the surface being cleaned. A flexible mount for each nozzle on a rigid, radial vacuum duct permits the nozzle to accommodate irregular and different textured surfaces being cleaned.
