A brushroll for a surface cleaning apparatus includes a brush dowel defining a central rotational axis which extends longitudinally through the brush dowel. The brush dowel includes bristle supports, sweeper supports, and a shroud surface extending between the bristle supports and the sweeper supports. A plurality of bristles protrude from the bristle supports.

A dirt separator for a vacuum cleaner includes a chamber having an inlet through which dirt-laden fluid enters and an outlet through which cleansed fluid exits the chamber. A disc located at the outlet rotates about a rotational axis and comprises holes through which the cleansed fluid passes. The inlet is defined by an end of an inlet duct that extends within the chamber, and a separation distance between the centre of the inlet and the centre of the disc is no greater than the diameter of the inlet.

A cleaner is disclosed, which comprises a main body including an suction inlet through which air containing dust enters, a dust separator provided to separate dust from the air while the air entering from the suction inlet is moving, a first dust collector configured to collect the dust separated by the dust separator, a cyclone portion configured to rotate the air to separate the dust from the air, and a second dust collector collecting the dust separated by the cyclone portion. The dust separator is provided with a plurality of plate shaped members arranged at a predetermined angle with respect to a moving direction of the air, and arranged to be spaced apart from one another to move the air.

A debris canister and filter assembly, which may be used in a vehicular vacuum cleaner, includes a debris canister having an inlet, an outlet, and a peripheral side wall. The peripheral side wall at least partially defines an interior space of the debris canister. A filter is disposed in the interior space of the debris canister, and includes filter media having a non-pleated portion and a pleated portion. The peripheral side wall forms a corner of the debris canister, and the filter media has a rounded-corner shaped to fit adjacent to the corner of the peripheral side wall.

A partition skirt device for a cleaning apparatus includes an inner ring and a skirt body. The skirt body includes: a root connected to the inner ring; an edge part arranged at an end of the skirt body away from the inner ring; and a plurality of collapsing parts arranged at intervals between the root and the edge part along a circumferential direction of the skirt body, and each extending along a radial direction of the skirt body. Along a thickness direction of the skirt body, the collapsing part protrudes relative to the skirt body on a first side surface of the skirt body and is recessed relative to the skirt body on a second side surface of the skirt body. On the first side surface of the skirt body, a size of a portion of the collapsing part protruding from the skirt body gradually decreases from the root to the edge part.

A dust scraping device for a cleaning apparatus includes a dust cup and a removable cyclone separation unit arranged in the dust cup. The dust scraping device includes a dust scraping member. The dust scraping member has a connection portion extending in a removal direction of the cyclone separation unit, and a dust scraping portion extending to an interior of the dust cup in a direction perpendicular to the removal direction and slidably abutting against the cyclone separation unit. The dust scraping device is mounted at the dust cup, and the dust scraping portion scrapes off at least part of debris on an outer side of the cyclone separation unit when the cyclone separation unit is removed from the dust cup.

A dirt collecting box assembly includes a dirt collecting box and a separating device. The dirt collecting box defines a dirt inlet, an air outlet, and a cavity, and the cavity communicates between the dirt inlet and the air outlet. The separating device is installed in the cavity of the dirt collecting box and is close to a top of the cavity. The separating device communicates between the dirt inlet and the air outlet. The air outlet communicates a fan assembly, and the fan assembly is configured to generate negative pressure through the air outlet, such that waste water enters the separating device via the dirt inlet under the negative pressure, and enters the cavity of the dirt collecting box after solid-liquid separation of the separating device.

A system for cleaning bagless vacuum cleaners using a first mixture having a surfactant, an odor neutralizer, a fragrance and microorganisms which is used to create a first solution including the first mixture mixed with water. The system includes a second mixture having baking soda, microorganisms, a desiccant and/or additional absorbing agents which is used to create a second solution when mixed with water. At least one component of a bagless vacuum is disassembled and soaked in the first solution, and after the at least one component of the bagless vacuum is dried and reassembled, the second solution is introduced to the interior of the bagless vacuum cleaner to maintain cleanliness.

A robot vacuum comprises a main body including a suction part for suctioning dust, and a dust canister, attachable to and detachable from the main body, and which separates dust from the air suctioned through the suction part and stores same. The dust canister includes: a first chamber which separates dust from the air flowing in from the suction part and storing same, and which includes an inclined surface so that the lower area thereof becomes narrower than the upper area thereof; and a second chamber which includes a cyclone unit and which separates dust from the air flowing in from the first chamber and stores same, and the first chamber can further include ribs formed along the inclined surface to facilitate discharge of dust so as to prevent the dust stored in the first chamber from becoming stuck, due to bottlenecking, in the lower area of the first chamber.
