Abstract
A sponge sander configured for selective attachment to a dust-collection system includes a housing having a housing-interior surface defining a sponge cavity and a sponge seat configured for removably retaining a determinately-dimensioned sanding sponge. The sponge has an abrasive sanding surface, a back surface opposite the sanding surface and a sponge periphery defined between the sanding and back surfaces. The sponge is retained within the sponge cavity such that (i) the abrasive sanding surface can engage a work surface to be sanded, (ii) fluid-flow channels are maintained between the sanding sponge and the housing-interior surface and (iii) the spaces are in fluid communication with a fluid port defined in the housing so that when a negative pressure is applied across the fluid port by a vacuum system external to the housing, dust created by sanding is drawn into the fluid-flow channels and out of the housing through the fluid port.
