Abstract
A vacuum cleaner includes a suction nozzle defining a nozzle inlet, a manual nozzle height adjustment assembly for adjusting the height of the nozzle inlet relative to a surface to be cleaned, and a bleed valve fluidly connected to a working air path of the vacuum cleaner to selectively open to reduce suction at the nozzle inlet. The bleed valve is incorporated with the nozzle height adjustment assembly such that movement of the nozzle height adjustment assembly between different height settings will automatically open or close the bleed valve.
