Vacuum bypass vent and vacuums incorporating such bypass vents

A vacuum appliance capable of picking up both wet and dry material, the appliance comprising:

• a drum;
• a powerhead atop the drum, the powerhead comprising—
• a motor,
• an impeller driven by the motor and configured to induce a liquid into the drum,
• an impeller chamber surrounding the impeller, and
• an impeller intake defining a path for air flow to impeller;
• a filter assembly between the drum and the powerhead, the filter assembly comprising—
• a filter cage,
• a float disposed within the filter cage, and
• a filter disposed around the filter cage,
• the filter assembly being adapted to be secured to the underside of the powerhead such that the float is configured to form an interface with the impeller intake to prevent the liquid from being ingested into the impeller chamber;
• and
• a bypass vent in the interface between the float and the impeller intake where the float meets the impeller intake, the vent configured to allow cooling air to reach the impeller chamber while the float is simultaneously preventing the liquid from being ingested into the impeller chamber.
