Patent

CA 2635621

The present disclosure provides a method and system to supply pumping capabilities to a wet and dry vacuum cleaner. A single motor can operate a vacuum unit and the pump distinct from the vacuum unit. A port in the vacuum flow path can act as a vacuum tap to prime the pump when necessary. The pump can directly pump the fluids without having to flow first into the drum container of the vacuum cleaner. The system can allow independent operation of the vacuum unit and the pump and at different, more optimal speeds for each, allowing a higher performance on each of the vacuum unit and the pump, since maximum power for the system can be provided to either the operating device while the other one is not operating. Accordingly, the disclosure further provides a system and method for separately engaging and disengaging the vacuum unit and the pump.
