摘要： A suction nozzle for a vacuum cleaner, the suction nozzle comprising a suction chamber, an outlet duct extending from the suction chamber for connection to a vacuum source on the vacuum cleaner, a soleplate for supporting the nozzle on a carpeted floor, a suction opening in the soleplate which opens into the suction chamber, and a valve which can be manually operated to open or close a bleed path through the front of the nozzle into the suction chamber, the bleed path being defined by a channel formed on the underside of the soleplate which is fluidly connected to the outlet duct, the channel terminating in an entrance slot on the front of the nozzle for admitting debris as the suction nozzle is pushed in a forward direction, the channel defining a throat downstream of the entrance slot, the throat having a smaller cross-sectional area than the entrance slot.
