Abstract (en)
[origin: WO2022207060A1] A vacuum cleaner (1) is disclosed comprising a fan (3), an electric motor (5) configured to power the fan (3), a control arrangement (21), and an output unit (7, 7'). The control arrangement (21) is configured to monitor a quantity representative of an electric current (Im) supplied to the electric motor (5) and is configured to increase a voltage (Vm) supplied to the electric motor (5) in response to a detected decrease in electric current (Im) supplied to the electric motor (5). The control arrangement (21) is further configured to output a notification via the output unit (7, 7') if the voltage (Vm) supplied to the electric motor (5) exceeds a threshold limit (Tl) during a first predetermined time (t1).
