Provided are a scrubber brush assembly and a vacuum cleaner having same. The scrubber brush assembly includes a roller brush body and a scraping sleeve. The roller brush body is rotatable around a first rotation center line and has a bristle (12) provided thereon. The scraping sleeve is rotatable around a second rotation center line noncoincident with the first rotation center line and sleeved over the roller brush body. The scraping sleeve has a scraping sleeve hole defined thereon. The bristle is adapted to be extended out of or retracted into the scraping sleeve hole in a wall thickness direction of the scraping sleeve.

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.

The present disclosure is generally directed to cleaning head for a vacuum system. The cleaning head includes an edge cleaner disposed on at least one side of the cleaning head to provide enhanced edge cleaning capabilities for the vacuum system.

A floor care appliance in the form of a brush vacuum cleaner having a brush set facing the floor for receiving a driven brush roller with an overload protection. A drive disk is mounted rotatably on the shaft and the shaft has a torque-proof output element to the brush roller and the drive disk is coupled via a torsion spring to a coupling disk which is displaceable axially on the shaft and which is coupled in a torque-proof manner via cams to the shaft. Ramps are formed on the drive disk which, above a torque threshold, axially adjust the coupling disk with corresponding ramps by relative twisting. A safety shutdown can be controlled via the adjusting movement via a corresponding switching element of a circuit arrangement.

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 drive mechanism for a vacuum cleaner having a motor and an agitator includes a belt coupled to the motor and the agitator to drive the agitator, and a belt tensioner operable to selectively tension the belt. The belt tensioner includes an arm movable relative to the belt, a shaft coupled to the arm, a pulley rotatably coupled to the shaft, a bearing positioned substantially within the pulley and around a portion of the shaft, and a member fixed to the pulley to retain the bearing within the pulley.

A removable rotatable driven agitator is used in a surface cleaning head and is driven by a drive mechanism that axially engages a driven end of the agitator. The removable rotatable driven agitator may be located in an openable agitator chamber for purposes of removing debris and/or removing the agitator. The openable agitator chamber may be covered by an external cover that is movable between an open position and a closed position. The removable agitator may be secured in the agitator chamber by the external cover. The removable rotatable agitator may have an end cap mounted on a rotatable bushing at a non-driven end and may have a splined driven member at the driven end to engage a splined drive member on the drive mechanism.

A surface cleaner may have various features including an engagement mechanism secured to an agitator support frame and positioned to be pivoted by an agitator lift lever as the agitator lift lever translates, the pivoting engagement mechanism lifting the agitator support frame and the agitator secured thereto from a lowered position to a raised position. Other features may include a projection to limit belt slack when the agitator assembly is raised, a compact detent mechanism for releasing a spine assembly in an upright surface cleaner, a compact motor drive assembly, a self-priming centrifugal pump, a fluid-dispensing system having a high flow operating state and a low flow operating state, and a clean-out tray in which a base of the surface cleaner may be docked.

An attachment for a vacuum cleaner includes a head, a brush roll, an electric motor, and an attachment conduit. The head includes a suction opening, a brush roll cavity, and a battery cavity defined therein. The brush roll cavity is in fluid communication with the suction opening. The battery cavity has an elongate shape and a first longitudinal axis. The brush roll is rotatably coupled to the head. A majority of the brush roll is disposed within the brush roll cavity. The brush roll is rotatable about a rotational axis. The electric motor is disposed within the head. The electric motor drives the brush roll. The attachment conduit is in fluid communication with the suction opening. The attachment conduit is coupled to the head and has a second longitudinal axis. Each of the first longitudinal axis and the second longitudinal axis is angled relative to the rotational axis.

A remote access duster with a body, a flexible duster cord loop that is configured to be propelled such that part of the loop moves outward from the body while another part moves inward toward the body, and a vacuum source that is configured to draw air over the cord.
