    Abstract: A prefilter for a filter of a vacuum device 1 includes a frame extending in an axial direction between first and second axial extents. The frame includes a base located at the first axial extent, a first cylindrical ring extending axially from the base toward the second axial extent, a plurality of ribs extending from the first cylindrical ring towards the second axial extent and defining openings between the ribs, and a second cylindrical ring portion positioned at the second axial extent of the frame. The prefilter also includes a mesh layer comprising a plurality of mesh openings, the mesh layer coupled to the frame and configured to cover the openings to prevent debris larger than a size of the mesh openings from passing therethrough. The prefilter also includes an engagement feature coupled to the frame and configured to engage the filter to fasten the frame to the filter.

    Abstract: A cleaning apparatus includes a cart having a base movable along a ground surface and a vacuum assembly removably receivable on the base. The vacuum assembly includes a power head, a collection container, and a suction inlet through which dust and debris is configured to be drawn via the power head into the collection container. The cleaning apparatus also includes a cleaning head coupled to the cart separate from the vacuum assembly such that the vacuum assembly is separable from the cleaning head when removed from the cart, the cleaning head configured to engage the ground surface and the dust and debris located thereon. The cleaning apparatus also includes a nozzle mounted at the cleaning head, the nozzle coupled to the suction inlet of the vacuum assembly and providing a suction path between the cleaning head into the collection container of the vacuum assembly.

    Abstract: A battery powered fan assembly includes a fan housing that at least partially defines an airflow chamber, a plurality of fan blades positioned within the airflow chamber, a motor operable to rotate the plurality of fan blades, a battery receptacle configured to receive a removably battery pack to power the motor, and a base assembly configured to be placed on a support surface. The base assembly includes a first frame segment coupled to the fan housing, a second frame segment pivotally coupled to the first frame segment, and a third frame segment pivotally coupled to the second frame segment. The base assembly is configured to be collapsed into a storage configuration in which each of the first, second, and third frame segments are folded onto each other and expanded to a first deployed configuration in which the fan housing is elevated above the support surface by a first height.
