A cleaner includes a main body and a suction head connected to the main body to suck foreign objects into the main body therethrough, the suction head including a housing including a suction port, and a drum module disposed in the housing, and to be rotated to scatter the foreign objects to be sucked through the suction port so that the scattered foreign objects are drawn into the housing through the suction port, and the drum module including a drum body, a first blade coupled to outer circumference of the drum body, a second blade separated from the first blade in a circumferential direction of the drum body and having a mass greater than a mass of the first blade, and a mass compensation member arranged on the outer circumference of the drum body to compensate for a difference in mass between the first blade and the second blade.

A surface cleaning apparatus has a suction motor actuator that is actuatable to actuate the suction motor to operate in a first mode of operation and to operate in a second mode of operation, the first mode of operation defining a first discrete power level for the suction motor and the second mode of operation defining a second discrete power level for the suction motor. The first mode of operation is enabled when the first power pack having a first level of power is provided to power the surface cleaning apparatus and the second mode of operation is not enabled until a second power pack is provided such that the surface cleaning apparatus has a second level of on board power that is greater than the first level of on board power.

A handheld vacuum cleaner includes a fluid flow path extending from a dirty air inlet to a clean air outlet, a main body, and a motor assembly positioned in the main body and along the fluid flow path. The motor defines a motor rotational axis. The handheld vacuum cleaner also includes a cyclonic chamber positioned in the fluid flow path. The cyclonic chamber defines a separator axis. The separator axis and the motor rotational axis form an obtuse angle extending between the cyclonic chamber and the motor assembly. The handheld vacuum cleaner further includes a pre-motor filter in the fluid flow path downstream from the cyclonic chamber and upstream from the motor assembly, a plenum in the fluid flow path immediately upstream from the motor assembly, and a sensor positioned on the plenum. The sensor is operable to measure a characteristic of the fluid flow path.

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.
