Abstract
A cleaner suction nozzle is provided in which provisions are made for a nozzle height elevation arrangement and a hose conversion valve arrangement. The hose conversion valve arrangement works in conjunction with the nozzle height elevation arrangement so that the suction nozzle can be elevated from the floor to disengage the cleaner agitator and then hose conversion of the cleaner can occur almost simultaneously.
