Techtronic Floor Care Technology Limited

A cleaning system including a motor configured to provide rotational energy, a current sensor configured to sense current provided to the motor, and a controller having an electronic processor. The controller is configured to receive, from the current sensor, a current signal indicative of the current provided to the motor, filter the current signal to produce a filtered current signal, and control the motor based on the filtered current signal.

The present disclosure relates to a battery powered floor cleaner ( 10 ). The floor cleaner ( 10 ) is operable in various modes based on the capacity of a battery pack ( 22 ), such as a normal power mode ( 40 ) and a low power mode ( 42 ).

A surface cleaner ( 10 ) includes a housing ( 12 ) having a first tank guide projection ( 82 ) that is received in a first recess of a supply tank ( 14 ) when the supply tank is in a supply tank operating position and the first tank guide projection includes a cooling air inlet ( 85 ) in fluid communication with a cooling air inlet of a pump housing ( 72 ). The housing further includes a second tank guide projection ( 84 ) that is received in a second recess of the supply tank when the supply tank is in the supply tank operating position and the second tank guide projection forms a cooling air flow path between the cooling air inlet of the first tank guide and the cooling air inlet of the pump housing.

A vacuum cleaner including a surface cleaning head having a brushroll rotatable about an axis defining an axial direction, and a brushroll housing at least partially surrounding the brushroll. The brushroll housing includes an outlet port disposed at a first axial location, and a bottom housing. The bottom housing includes a front wall, a rear wall spaced from the front wall to define the suction inlet, and at least one rib disposed below the brushroll and extending across the suction inlet between the front and rear walls. Each rib includes a forward portion connected to the front wall, a rearward portion connected to the rear wall, and a central portion extending linearly orthogonal to the axial direction between the forward and rearward portions. The rearward portion is turned toward the first axial location of the outlet port to define a flow guide.

A surface cleaning apparatus comprises a brushroll that rotates about an axis. The brushroll defines a cylindrical portion and the axis extends centrally through the cylindrical portion. The brushroll also includes a rib that extends in a direction away from the axis. The rib includes a face extending along a line that is collinear with a secant through the cylindrical portion. A brush member extends from the face.

A surface cleaner configured to distribute a liquid to a surface to be cleaned. The surface cleaner includes a supply tank and a recovery tank that are removable from the surface cleaner.

A surface cleaner ( 10 ) includes a main body ( 12 ), a base ( 14 ), and a column ( 18 ) extending from the base. A supply tank ( 42 ) extends around a first portion of the column. A first end of the supply tank is on a first side of the column. A second end of the supply tank is on a second side of the column. A recovery tank ( 46 ) extends around a second portion of the column. A first end of the recovery tank is on the first side of the column. A second end of the recovery tank is on the second side of the column. The first end of the supply tank is adjacent the first end of the recovery tank. The second end of the supply tank is spaced from the second end of the recovery tank. A battery ( 98 ) is coupled to the main body between the second ends of the supply and recovery tanks.
