Abstract:
A vacuum cleaner comprising a vacuum motor and a power supply. The power supply comprises input terminals for connection to an AC source, output terminals connected to the vacuum motor, an AC-to-DC stage, and a battery. The AC-to-DC stage converts alternating current drawn from the AC source into direct current that is supplied to the battery and the vacuum motor. The power supply operates in a first mode when disconnected from the AC source and a second mode when connected to the AC source. In the second mode, the vacuum motor operates in either a low-power state or a high-power state. In the low-power state, the vacuum motor and the battery each draw power from the AC source such that the battery charges. When the vacuum motor operates in the high-power state, the vacuum motor draws power from both the AC source and the battery such that battery discharges.

Claim (Index 9):
The vacuum cleaner of  claim 8 , wherein, when the voltage of the battery drops below a further threshold, the AC-to-DC stage increases the power drawn from the AC source such that the power drawn from the AC source by the AC-to-DC stage is greater than the power drawn from the power supply by the vacuum motor.
