A cleaner head comprises an agitator supported for rotation about a rotation axis. The cleaner head has a spool which comprises a narrowed waist positioned axially between two radially enlarged portions. The axial end of the agitator terminates in a rim positioned radially outward from and axially in line with the narrowed waist, and is configured to allow hair wrapped around the agitator to travel axially along it and slip off the rim onto the narrowed waist.

The present disclosure relates to an automatic cleaning device and a sweeping assembly thereof. The sweeping assembly includes: a brush holder, a brush body disposed at least partially in the brush holder; and an anti-winding structure. The anti-winding structure is located at a joint of the brush body and the brush holder, where the anti-winding structure is configured to at least partially fill a gap at the joint when the sweeping assembly is in a working state.

The present invention relates to a cleaner head including: a housing having an air outlet formed on the rear side thereof; a brush disposed exposedly from the underside of the housing in such a manner as to be extended in a longitudinal direction thereof and having both longitudinal ends rotatable to the housing by means of bearing modules; a driving motor built in the housing to rotate the brush through a power transmission mechanism; one side frame and the other side frame disposed on both longitudinal ends of the housing respectively; and a brush detachable module disposed on one side frame to detachably mount the bearing module disposed on one end of the brush in a lateral direction of the brush, whereby the brush can be easily mounted on the housing and one side frame, and further, the brush can be prevented from escaping by itself from the housing and one side frame while being used.

The disclosure is directed to novel predictive methods and personalized therapies for treating asthma. Specifically, this disclosure relates to methods of treating a patient having asthma by selectively administering an IL-13 antagonist, on the basis of that patient being genetically predisposed to have a favorable response to treatment with the IL-13 antagonist. Also disclosed herein are transmittable forms of information, diagnostic methods, and kits useful in predicting the likelihood that a patient having asthma will respond to treatment with an IL-13 antagonist.

A cleaner head includes an agitator; a housing defining an agitator chamber and an aperture through which the agitator can be removed from the agitator chamber; and an end cap attachable to the housing to close the aperture, and releasable from the housing to open the aperture. The end cap is attachable and releasable by rotating at least a locking portion of the end cap about a locking axis between locked and unlocked positions relative to the housing. The cleaner head has a latch mechanism configured to prevent rotation of the locking portion to the unlocked position. The latch mechanism has a release member which is provided on the end cap, the release member being operable by hand to release the latch.

A robotic cleaner may include a chassis, an agitator assembly configured to engage a surface to be cleaned, and a lift mechanism moveably coupling the agitator assembly to the chassis. The lift mechanism may include a biasing mechanism. The biasing mechanism may be configured to generate a biasing force that urges the agitator assembly in a direction away from the surface to be cleaned. The biasing force may be insufficient to lift the agitator assembly from the surface to be cleaned.

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.

An example of a surface cleaning head may include a main body, a neck pivotally coupled to the main body, a stabilizer, and a linkage pivotally coupled to the main body and the stabilizer. The linkage may be configured to cause the stabilizer to transition between an extended position and a retracted position in response to a pivotal movement of the neck.

A cleaning device including a main body configured to be movable along a plane; a first roller longitudinally extending in a first direction and rotatable; a first brush on an outer circumferential surface of the first roller; a driver configured to generate power to rotate the first roller; a second roller longitudinally extending in the first direction and spaced apart from the first roller by a first distance and rotatable; and a second brush on an outer circumferential surface of the second roller, wherein the first roller and the second roller are configured so that the first roller is rotatable in a first rotation direction around a longitudinal axis of the first roller, the second roller is rotatable in the first rotation direction around a longitudinal axis of the second roller, the first and the second brush overlap within a first range, and the first distance exceeds the first range.

Disclosed is a cleaner having a structure that a supporting member and a cleaning module are coupled to or separated from a cleaner body. The cleaner includes a cleaner body having a module mounting portion; a supporting member inserted and mounted to the module mounting portion, and separated and withdrawn from the module mounting portion, through a bottom part of the cleaner body; and a cleaning module coupled to the supporting member so as to be inserted or withdrawn together with the supporting member when the supporting member is inserted or withdrawn.
