Vacuum cleaners to be mounted in a vehicle are disclosed. Some of the vacuum cleaners have a modular design that allows the vacuum cleaners to be arranged, assembled, and/or installed in different configurations and to fit in different spaces within the vehicle. Vacuum cleaners may include a vacuum module, a collector module, and/or a hose storage module. An interconnecting duct is configured to operatively couple the vacuum module and the collector module in any one of a plurality of different predefined assembly configurations. The collector module may have a debris canister that may be lifted straight out of a collector housing. The vacuum cleaner may be installed in a vehicle in a manner to allow easy removal of the debris canister without disconnecting and/or removing other portions of the vacuum cleaner.

Methods for controlling the power supply of a vacuum cleaner motor
11101088 · 2021-08-24 · ·

Applicant has created systems, methods, and apparatuses for controlling the power supply of a vacuum cleaner motor. The systems and apparatuses include pressure taps to detect a pressure differential within a vacuum cleaner, a float that adjusts depending on an amount of liquid stored, and a power switch that toggles based on the pressure differential created by the position of the float. Alternatively, the float can be replaced by an air chamber so that the pressure differential is created by liquid rising above the volume of air trapped in the chamber. The method can include interrupting the current supplied to an electrical circuit of a power switch based upon a pressure differential created within the vacuum. By controlling the power supply to a vacuum cleaner motor based on a pressure differential created by the amount of liquid stored within the vacuum cleaner, the vacuum cleaner can automatically disable the vacuum cleaner's motor as the vacuum approaches its maximum liquid capacity.
