A stepless speed regulatable handy dust cleaner is disclosed, which includes: a housing, a battery, a blower mechanism, a control module, an air filter mechanism, and a blow pipe. A side of the housing is provided with an air outlet opening, and another side of the housing is provided with an air filter opening. The housing includes a first mounting shell and a second mounting shell, each of which includes a handgrip part and an air outlet part. The first mounting shell is provided with a knob slot, where a knob is provided. The blower mechanism includes a motor, a motor board, a blower casing and a fan blade. The motor is drivingly connected to the fan blade. The battery, the control module and the motor are electrically connected to each other. When the knob is rotated clockwise, the air volume and flow pressure gradually increase. When the knob is rotated counterclockwise, and the air volume and flow pressure gradually decrease.

A method for charging an energy storage device for use in a cleaning appliance includes the following steps: reading an energy demand signal representative of an energy required by the cleaning appliance for a predetermined cleaning run; and outputting a charging signal using the energy demand signal, the charging signal causing the energy storage device to be charged as a function of the energy required.

A hand vacuum cleaner has an upstream air treatment stage having an upstream air treatment member and a longitudinal axis extending between the front and rear ends of the downstream air treatment stage, and a downstream air treatment stage a downstream air treatment member and a downstream dirt collection chamber that is exterior to the downstream air treatment member. The downstream air treatment member is positioned rearward of the upstream air treatment member. The downstream dirt collection chamber extends forward of the downstream air treatment member to a location that is forward of the rear end of the upstream air treatment stage.
