A brushroll dowel for a vacuum cleaner has a bristle stiffener protruding from a brush dowel. A plurality of stiffened bristles protrude from the brush dowel adjacent to the bristle stiffener, and a plurality of unstiffened bristles also protrude from the brush dowel and are non-adjacent to the bristle stiffener.

A surface cleaning apparatus includes a rotatably mounted brush associated with a dirty air inlet. A plurality of bristles extend outwardly from a radial outer surface of the rotatably mounted brush. A heating element that is positioned exterior to the brush core.

A wire cleaning apparatus and method is provided, in which a wire cleaning apparatus includes a passive brush mechanism comprising a helical brush, the helical structure having a helical axis substantially coincident with path of a wire passing through the wire cleaning apparatus. The helical brush includes a plurality of first bristles generally oriented inwardly from the helical structure toward the wire, and the helical brush may be compressed or extended to adjust the inner diameter of the helical brush. The wire cleaning apparatus further comprises an active brush mechanism disposed around the wire and configured to rotate around the wire. The active brush mechanism comprises at least one cylindrical brush having a plurality of second bristles disposed on a cylindrical surface such that one or more of the plurality of second bristles impinge upon the wire. The at least one cylindrical brush having a cylindrical axis about which the at least one cylindrical brush is configured to rotate relative to the active brush mechanism.

A surface cleaning apparatus includes a rotatably mounted brush associated with a dirty air inlet. A plurality of bristles extend outwardly from a radial outer surface of the rotatably mounted brush. The brush roll is provided with at least one hard floor cleaning pad and at least one flexible protective pad member.

A surface cleaning apparatus includes a rotatably mounted brush associated with a dirty air inlet. A plurality of bristles extend outwardly from a radial outer surface of the rotatably mounted brush. A hair blocking member is positioned between a forward rotational side of the bristles and a rearward rotational side of the bristles.

A jet cleaning structure of a cleaning robot mainly comprising at least one jet port and one roller brush, wherein the jet port is disposed at a perimeter of a suction port at the bottom of the cleaning robot and is provided for ejecting air towards the underside of the suction port; the roller brush includes a shaft and a plurality of hard brush rods, wherein two ends of the shaft are disposed in a roller groove at the bottom of the cleaning robot, the plurality of hard brush rods is arranged in a straight or helical manner in equal parts on the shaft, when the cleaning robot is moving, the cleaning robot drives the shaft to rotate with respect to the moving direction of the cleaning robot so that the cleaning robot can use the plurality of hard brush rods to push away the fluff of the carpet and use the jet port to eject air to blow away the dust and foreign substance accumulated at the bottom of the fluff, thereby allowing the suction port disposed at the bottom of the cleaning robot to suck in the dust and foreign substance accumulated at the bottom of the fluff to the dust box and to effectively clean the carpet.

A cleaner head for a vacuum cleaning appliance includes a main body, a front agitator and a rear agitator, each agitator being rotatable relative to the main body, a mechanism for rotating the front agitator and the rear agitator, and a surface agitating edge located between the front agitator and the rear agitator.

A cleaning apparatus may include at least one isolator configured to absorb mechanical vibration generated by contact between an agitator and a combining unit to reduce noise and/or vibration. The isolator may include at least one combing isolator disposed at least partially between the combing unit and the surface cleaning head. Alternatively (or in addition), the isolator may include a panel isolator disposed at least partially between a housing of the cleaning apparatus and a panel.

A vacuum cleaner includes a main body, a suction motor in the main body, an extension pipe, a suction head, connected to the suction motor through an extension pipe and including a suction port through which the foreign substances are sucked, a brush inside the suction head, a brush motor configured to rotate the brush, a pressure sensor configured to detect a pressure of air flowing through the suction port, a memory configured to store reference data used to identify the type of surface to be cleaned and a learning model to update the reference data, and a controller configured to determine a suction pressure based on the detected pressure and an atmospheric pressure, and identify the type of surface using the determined suction pressure, a load of the brush motor, and the stored reference data, and to update the stored reference data based on a predetermined update condition.

A surface cleaning head includes a housing having a front side and back side, a brush roll rotatably mounted to the housing within a suction conduit and having at least a portion proximate the opening of the suction conduit, a leading roller mounted to the housing in front of the brush roll, and a drive mechanism operatively coupled to the brush roll and the leading roller for driving the brush roll and the leading roller at same time. The brush roll includes an agitator body and a first bristle/flap arrangement comprising a first deformable flap extending from the agitator body and a first bristle strip and/or row of tufts extending from the agitator body and disposed adjacent to the first deformable flap. The first deformable flap is disposed at an aggressive angle and the first bristle strip and/or row of tufts is arranged at a passive angle.
