Abstract: An agitator for a vacuum cleaner includes an agitator body and a resiliently deformable flap. The resiliently deformable flap includes a front face, a rear face, and one or more protrusions extending outwardly from the front face. An agitator for a vacuum cleaner includes an agitator body and a bristle strip and/or a plurality of tufts arranged in one or more rows along the agitator body. The bristle strip and/or a plurality of tufts includes a first bristle group including a plurality of nylon bristles and at least a second bristle group including a plurality of para-aramid bristles.

Abstract: For motion transformation an apparatus includes a key and a plunger. The key moves along a first axis in a linear key displacement direction and along the first axis in a linear key return direction that is opposite the key displacement direction. The key includes a motivating arm on a distal end. The motivating arm includes a displacement cam surface disposed on a ventral side of the motivating arm and a return cam surface disposed on a dorsal side of the motivating arm. The plunger moves along a second axis. The plunger includes a displacement interface that is motivated by the displacement cam surface in response to the key moving in the key displacement direction to motivate the plunger in a plunger displacement direction. The plunger further includes a return interface.
