ABSTRACT:
The disclosure concerns a compact wet-dry vacuum cleaner adapted for collecting both wet and dry materials. The vacuum cleaner is powered by a by-pass type blow motor which is supported in a housing. The housing includes a baffle for separating the inflowing cooling air to the motor from the outflowing air which has cooled the motor. The placement of inlets and outlets to the motor housing prevents debris and liquid from splashing on the motor. A materials collection tank is separably attached to the motor housing to enable the tank to be removed for cleaning. The tank includes a nozzle at its front wall, which nozzle has an exit near the top of the tank. A curved air flow redirector at the top of the tank separates collected material from the air. The outlet from the tank is laterally spaced from the flow redirector. The motor housing is attached to a swivelable cover that extends over the motor. The cover extends over a duct that communicates between the materials collection tank and the blow motor. The cover is latched closed to the collection tank for forming the complete vacuum cleaner. Access to the tank is obtained by raising the cover off the tank. A power regulator at the duct determines the flow rate of the air being sucked into the suction inlet. A handle, swivelable to various positions during use and storage, is connected to the cover.
