Abstract: A surface cleaning apparatus including a body defining an agitation chamber, an agitator partially disposed within the agitation chamber and configured to rotate about a pivot axis, and a debrider at least partially disposed within the agitation chamber. The agitator includes an elongated body having a first and a second end, a sidewall extending radially outward from the elongated body extending between the first and the second ends, and a plurality of bristles extending radially outward from the elongated body. The plurality of bristles are arranged in at least one row adjacent to the sidewall. The debrider includes a plurality of teeth configured to contact a portion of the sidewall as the agitator rotates about the pivot axis.

Abstract: Devices, systems, and methods of the present disclosure are generally directed to facilitating user control of high-pressure flow of liquid for oral irrigation carried out as part of personal dental care. Such control over high-pressure flow may reduce the likelihood of errant spray of liquid outside of the user's mouth (e.g., onto mirrors, countertop surfaces, or the user's clothes). Such improved control over errant spraying may reduce the potential for frustration and, thus, may promote maintaining oral irrigation as part of a personal dental care routine. Further, or instead, through facilitating user control of high-pressure flow of liquid, the devices, systems, and methods of the present disclosure may improve the effectiveness and efficiency of self-administered oral irrigation in promoting a user's oral hygiene.

Abstract: An agitator including an elongated main body configured to rotate about a pivot axis, one or more soft cleaning features coupled to and extending over a substantial portion of a surface of the elongated main body, the one or more soft cleaning features defining at least one channel, and at least one deformable flap disposed at least partially within the at least one channel and extending from the elongated main body. The deformable flap may extend beyond an outer surface of the soft cleaning features. The channel may have a generally U shape and/or V shape. The channel may be configured to allow the resiliently deformable flap to move front to back as the agitator rotates about the pivot axis.

Abstract: An agitator for a vacuum cleaner including an elongated main body extending along a pivot axis and having first and second opposite lateral ends, one or more soft cleaning elements extending from elongated main body between the first and second opposite lateral ends, one or more channels formed within the one or more soft cleaning elements and disposed between the first and second opposite lateral ends, and one or more deformable flaps disposed within the one or more channels and extending from the elongated main body.

Abstract: A nozzle having castellations provides high suction pressure while also allowing for large pieces of debris to pass through inlet openings. In more detail, a nozzle for a surface treatment/cleaning apparatus is disclosed herein. The nozzle provides a suction channel through which debris passes into a main body of the surface treatment apparatus. Castellations are provided along a leading edge of the nozzle to allow debris to pass through the leading edge to the suction channel, and into the main body during, for instance, forward and reverse strokes of the surface treatment apparatus. In an embodiment, the castellations further include receptacles/cavities to receive and securely hold wheels therein. The wheels may extend from the nozzle at a predefined angle, also referred to herein as a camber angle, to improve vacuum handling and reduce noise during operation.
