Patent ID: 8438693

Claim:
A vacuum cleaner comprising: a cleaner body capable of standing and inclining; an electric blower accommodated in the cleaner body; a floor nozzle provided at a bottom of the cleaner body, the floor nozzle being capable of cleaning a surface while the cleaner body inclines; a mode detector for detecting whether the cleaner body is in a standing position or is in an inclined position which is inclined relative to the standing position; and a hose detachably attached to the floor nozzle, the hose allowing the cleaner body to communicate with the floor nozzle; and a hose detector detecting whether or not the hose is attached to the floor nozzle, a controller operable to supply a first power level to the electric blower to provide a first amount of suction if the mode detector detects that the cleaner body is in the inclined position, and supply a second power level greater than zero and lower than the first power level to the electric blower to provide a second amount of suction greater than zero and lower than the first amount of suction if the mode detector detects that the cleaner body is in the standing position, and if the hose detector detects that the hose is attached to the floor nozzle, and supply a third power higher than the second power and lower than the first power level to the electric blower if the mode detector detects that the cleaner body stands and additionally the hose detector detects that the hose is detached from the floor nozzle.
