Publication number: 20210177223Abstract: 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.Type: ApplicationFiled: December 17, 2020Publication date: June 17, 2021Inventors: Daniel R.

Publication number: 20170215667Abstract: A cleaning apparatus includes a combing unit including a series of spaced protrusions or teeth extending into a cleaning roller for preventing build up and removing debris (such as hair, string, and the like). The protrusions extend along a substantial portion of the cleaning roller and extend partially into the cleaning roller to intercept the debris as it passes around the roller. The protrusions have angled leading edges that are not aligned with a rotation center of the cleaning roller and are directed into or against a direction of rotation of the cleaning roller. The combing unit and protrusions have a shape and configuration designed to facilitate debris removal from the cleaning roller with minimal impact on the operation of the cleaning apparatus. The cleaning apparatus may include a surface cleaning head of an upright vacuum cleaner or sweeper or a robotic vacuum cleaner.Type: ApplicationFiled: April 20, 2017Publication date: August 3, 2017Inventors: Jason B.
