A vacuum cleaner for use with both dry and wet operation is formed of a housing which encloses a blower and a motor for driving the blower, the cleaner further including a canister having a nozzle and a storage chamber beneath the nozzle, which canister is removably securable to the front end of the housing. An intake port for air under suction is provided at the front end of the housing, the port having a liquid-deflecting hood extending from an upper portion thereof into the chamber for deflecting any liquid exiting from a posterior port of the nozzle into the chamber. The intake port for the entry of the air under suction is formed within a partition which extends across the housing, the lower portion of the partition serving as a wall which extends upward from the bottom of the housing to the bottom of the intake port to retain liquid, separated from the air stream, within the chamber. An alternative embodiment of the intake port is configured as an inlet chamber having a front wall with a forwardly extending snout, the opening of the snout being positioned above an exit port of the nozzle.read more
