Abstract
A filter cleaning system for a vacuum that includes a housing that is open across its top end and is arranged to be covered by a removable lid whereon is mounted a vacuum source. The housing includes a hose port for connection to a vacuum hose, and the housing can be mounted on wheels, casters, or the like. A double filter system, that includes separate primary and secondary filters, is arranged within the housing, with the secondary filter mounted across the vacuum source inlet, and with the primary filter, that is a bag connected to the lid undersurface, for containing the secondary filter and a filter support. The filter support is a rigid fame connected at a fight angle to an end to a straight rod that extends through the lid to be manipulated by an operator to move the filter support so as to engage surfaces of both the primary and secondary filters, to vibrate and shake collected particles therefrom. The secondary filter is mounted to the lid undersurface over a cage that is spring mounted to the lid, and extends across the vacuum inlet, with the cage to engage when moved a bottom surface of the secondary filter. Thereby, when the filter support strikes the bottom of the secondary filter, that contact will deflect the cage against its spring mounting, with the cage then rebounding to strike the inner face of the secondary filter bottom, further shaking and vibrating that filter bottom so as to dislodge particles therefrom that then fall into the primary filter.
