Abstract: A vacuum appliance capable of picking up both wet and dry material is described, wherein the vacuum appliance includes an impeller configured to induce liquid into the vacuum appliance, a motor configured to turn the impeller, a restrictor assembly to prevent the liquid from being ingested into the motor, and a bypass vent assembly configured to allow sufficient air to reach the motor in order to keep the motor cool while the restrictor is preventing the liquid from being ingested into the motor. The vacuum appliance also includes a drum configured to retain the liquid and an impeller intake between the impeller and the drum. The restrictor may comprise a float configured to rise with a level of the liquid in the drum and prevent the liquid from entering the impeller intake. The bypass vent assembly may be configured to allow airflow to bypass the restrictor and/or the drum.

Abstract: Applicants have created vacuum systems and apparatuses for a hanging wall wet/dry vacuum with detachable blower and slide out drum removal. The vacuum apparatus can include a removable powerhead (such as a blower), a removable drum, and a base unit that can be coupled to the external surface (such as a wall) when the removable powerhead is decoupled from the base unit. The system can include the vacuum apparatus and an external surface mounting device adapted to mount the vacuum apparatus to the external surface. Because the powerhead can be removed from the base unit while coupled to the external surface, an operator can enjoy an increased portability and functionality of the powerhead. Further, because the drum can be similarly removed from the base unit, an operator can quickly and efficiently clean the drum without removing the entire vacuum apparatus from the external surface.
