Abstract
Abstract A vacuum cleaner apparatus is disclosed, including a housing and a blower disposed in the housing. There is a power source for driving the blower and a substance collection container is detachably engaged with the housing and includes an inlet portion formed therein. A suction section extends generally between the blower and the substance collection container and includes a first port disposed in the container. An intake section is engaged with the inlet portion of the container and includes a second port disposed in the container. An actuator selectively connects the blower with the power source to operate the blower and opens the first and second ports to create a vacuum in the container such that the air and accompanying substances are drawn through the intake section into the container. The actuator also selectively disconnects the blower from the power source and closes the first and second ports to terminate air flow and restrict substance movement into and out of the container.
