ABSTRACT:
A floor mounted sweeping suction inlet is provided with a door that carries a user-activated portion by which the door may be opened by contact from a foot. This makes it unnecessary for the householder to bend over to activate the vacuum-operated waste collection system. The vacuum source can be turned-on automatically by opening the door by the presence of a door-activated electrical switch. An adapter converts the floor-mounted vacuum opening to a standard circular opening for receiving a vacuum hose and wand.
