A tool for a surface cleaning apparatus, including a floor head including a floor facing surface which defines an inlet for receiving dirt-laden air, which inlet is generally positioned in a first plane P; a passage for carrying dirt-laden air from the floor head to the apparatus; a connecting member for connecting the tool to a surface cleaning apparatus, wherein the floor head and connecting member are pivotally connected about an axis A; and a blocking device for inhibiting pivotal movement of the connecting member about axis A. The blocking device is moveable to a blocking condition in which pivotal movement of the connecting member downwardly outside of a pre-determined use condition is inhibited.

A handheld vacuum cleaner (10), including a main body (22) having a handle (98), a motor assembly (114) positioned within the main body, and a cyclonic separator assembly (26) removably coupled to the main body. The cyclonic separator assembly includes an inlet nozzle (42) having a dirty air inlet (14) positioned in the front of the handheld vacuum cleaner when the cyclonic separator assembly is coupled to the main body, and a cyclonic chamber (30) in fluid communication with the dirty air inlet. The cyclonic chamber defines a separator axis (34). The cyclonic separator assembly further includes a dirt collection region (38) configured to receive debris separated in the cyclonic chamber. The inlet nozzle includes an upstream height (270) measured perpendicular to the inlet axis and a downstream height (274) measured parallel to the separator axis. The downstream height is larger than the upstream height.

A surface cleaning apparatus, such as a portable surface cleaning apparatus is powered by one or more ultracapacitors and a charging unit for same is provided.

The present invention relates to a cleaning appliance and a method for a cleaning appliance. In particular, a cleaning appliance is disclosed, comprising: a housing, comprising an opening facing toward a surface to be swept; a sweeping brush, having a connection part by means of which the sweeping brush is mounted in the housing, and being capable of rotating about a rotation axis by receiving a driving force, so as to perform a sweeping operation; and a toothed structure arranged close to an end of the sweeping brush, the toothed structure being provided between the housing and the sweeping brush and comprising multiple teeth, the multiple teeth extending from one of the housing and the sweeping brush toward the other of the housing and the sweeping brush. The cleaning appliance of the present invention is at least able to prevent or at least reduce the entry of foreign matter into a gap, as well as promptly trigger protection measures when necessary to remind a user to deal with the problem, in order to avoid failure due to melting of the housing and sweeping brush in a connection region.
