1. A vacuum cleaner comprising:
a base having a lower surface configured to face a surface to be cleaned, and first and second side edges that are spaced in a lateral direction to define lateral portions of an outer perimeter of the base; a main suction inlet on the base facing the surface to be cleaned, the main suction inlet being elongated in the lateral direction; a first edge cleaning inlet on the base facing the surface to be cleaned, the first edge cleaning inlet being located adjacent the first side edge of the base; a handle pivotally connected to the base by a pivot joint; a first valve mounted on the handle, the first valve comprising:
a main floor cleaning inlet,an auxiliary cleaning inlet,a valve outlet,a first flow controller movable between a main floor cleaning position in which the valve outlet is fluidly connected to the main floor cleaning inlet, and an auxiliary cleaning position in which the valve outlet is fluidly connected to the auxiliary cleaning inlet, anda first actuator configured to move the first flow controller between the main floor cleaning position and the auxiliary cleaning position; a first suction passage fluidly connecting the main suction inlet to the main floor cleaning inlet; a second suction passage fluidly connecting the first edge cleaning inlet to the auxiliary cleaning inlet; a second valve mounted on the handle, the second valve comprising:
a second flow controller movable between an edge cleaning position in which the first edge cleaning inlet is in fluid communication with the auxiliary cleaning inlet, and an accessory cleaning position in which the first edge cleaning inlet is not in fluid communication with the auxiliary cleaning inlet, anda second actuator configured to move the second flow controller between the edge cleaning position and the accessory cleaning position; an accessory hose having an open distal end and a flexible hose fluidly connecting the open distal end to the auxiliary cleaning inlet; an accessory hose mount located on the handle and configured to hold the accessory hose in a hose storage position in which the accessory hose contacts the second actuator to hold the second flow controller in the edge cleaning position; a dirt separator mounted on the handle and having a dirt separator inlet in fluid communication with the valve outlet; and a suction motor operatively associated with the handle or the base, the suction motor being configured to generate a suction airflow through the dirt separator, wherein the suction airflow may be selectively received, by operation of the first valve and the second valve, from each of the main suction inlet, the first edge cleaning inlet, and the open distal end of the accessory hose. |
