An attachment for cleaning a socket is provided including a body with an insertion section of the body for insertion into the socket along an insertion direction and with a connection section of the body for connection to a suction inlet of a vacuum cleaner, the attachment including at least one cleaning element for mechanical cleaning of an inner surface of the socket. The attachment includes at least one bearing element attached to the body, wherein the cleaning element is rotatably mounted on the bearing element relative to the body about an axis of rotation aligned along the insertion direction, and at least one drive element attached to the body for automatically rotating the at least one cleaning element about the axis of rotation. A method for cleaning a socket with the attachment is also provided.

REDUCING CLEANING ROLLER AMPLITUDE AND SPEED OSCILLATIONS OF A CLEANING ROBOT

A roller assembly for a mobile cleaning system for cleaning a work surface can include a drive shaft, a sheath, a bushing, and a bushing shroud. The drive shaft can be rotatable about a drive axis, and the drive shaft can include a driven end and an opposite bushing end. The sheath can be supported by the drive shaft and the sheath can be rotatable with the drive shaft. The sheath can include a shell engageable with the work surface. The bushing can be located about the bushing end of the drive shaft. The bushing shroud can be connected to the bushing. The sheath and the drive shaft can be together rotatable with respect to the bushing and the bushing shroud, the bushing shroud can include an outer portion defining a first radius of curvature and a recessed portion connected to the outer portion.

CLEANER HEAD FOR A VACUUM CLEANER

A cleaner head for a vacuum cleaner includes a suction cavity having an opening through which debris enters the cleaner head, and an air outlet, and an agitator mounted in the suction cavity in a cantilevered manner for rotation relative thereto. The agitator is conical in shape and has a first, free end and a second end which has a larger diameter than the first end. The air outlet is located adjacent the free end of the agitator.

CLEANER HEAD FOR A VACUUM CLEANER

A cleaner head for a vacuum cleaner includes a suction cavity comprising an opening through which debris enters the cleaner head, and an outlet. An agitator is mounted in the suction cavity in a cantilevered manner for rotation relative thereto. The agitator includes a core having a first, free end, a second end remote from the free end, and upstanding helical ridges extending between the free end and the second end, and a row of bristles located between the helical ridges and inclined relative to the core in a direction extending towards the free end of the core.

Floor cleaner

A floor cleaner including a base that includes a suction inlet, a brushroll chamber, and brushroll. The base further includes a brushroll cover releaseably attached to the base, the brushroll cover removable to access the brushroll chamber. The brushroll chamber includes a brushroll, an endcap, a tab extending from the endcap, a driven end and a non-driven end. The endcap includes the tab extending from the endcap. The tab is movable between an unfolded and a folded position. Upward movement of the tab in the unfolded position removes the brushroll from the brushroll chamber.

Brushroll and floor cleaner
11206962 · 2021-12-28 · ·

The present disclosure provides a floor cleaner that includes a replaceable component, such as a brushroll or a filter. The floor cleaner has a detection mechanism comprising a magnet on the replaceable component and a Hall Effect sensor positioned to detect the permanent magnet when the replaceable component is correctly installed on the floor cleaner. Operation of one or more electrically-powered components of the floor cleaner is prevented when the permanent magnet is not detected by the Hall Effect sensor.
