  • Publication number: 20260041293
    Abstract: Various illustrative handheld surface cleaners and methods of using handheld surface cleaners are provided. In an exemplary implementation, the handheld surface cleaner is configured to use suction to draw debris into the handheld surface cleaner. The suction also causes air to be drawn into the handheld surface cleaner. The handheld surface cleaner is configured to separate the air and the debris on board the handheld surface cleaner to allow the air to exit the handheld surface cleaner and to allow the debris to be collected in the handheld surface cleaner for later disposal.

  • Publication number: 20240298857
    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.
