Reconfigurable modular brush and associated brush kits

A reconfigurable modular brush comprising:

• a brush head including brush-head upper and lower surfaces extending longitudinally along a brush-head axis between brush-head first and second ends and laterally opposed brush-head first and second sides extending between the brush-head upper and lower surfaces and longitudinally between the brush-head first and second ends;
• a bristle array defined by a plurality of bristles protruding from the brush-head lower surface;
• and
• a brush handle including a grip portion configured for grasping by a human hand and a brush-head mount, the brush handle having a lengthwise extent disposed generally along a handle axis between handle proximate and distal ends, the brush head and brush-head mount being cooperatively configured such that the handle can selectively capture and retain the brush head, and the brush head being itself further being configured as a hand brush such that, when separated from the brush-head mount of the brush handle, the brush head can be grasped directly with a user's palm and multiple fingers of the same hand to engage a work surface, wherein
• the brush head and the brush-head mount are complimentarily keyed such that the brush-head mount and the brush-head upper surface can be brought into direct mutual contact for selective capture of the brush head by the handle through each of two methods including (i) longitudinal insertion along the brush-head axis and (ii) top-down mounting in a direction perpendicular to the brush-head axis, and
• each of the two methods of bringing the brush-head mount and the brush-head upper surface into direct mutual contact can be performed both (i) exclusively of the other method and (ii) in combination with the other method.

• and
• a brush handle in the form of an adaptor including a grip portion configured for grasping by a power tool and a brush-head mount, the brush handle having a lengthwise extent disposed generally along a handle axis between handle proximate and distal ends, wherein
• the brush head and brush-head mount are cooperatively configured such that the adaptor can selectively capture and retain the brush head,
• the brush head and brush-head mount are complimentarily keyed such that the brush-head mount and the brush-head upper surface can be brought into direct mutual contact for subsequent mutual interlocking by each of two methods including (i) longitudinal insertion along the brush-head axis and (ii) top-down mounting in a direction perpendicular to the brush-head axis, and
• each of the two methods of bringing the brush-head mount and the brush-head upper surface into direct mutual contact can be performed both (i) exclusively of the other method and (ii) in combination with the other method.
