Provided is a cleaner, wherein because auto power off control is performed using a simple configuration, power is automatically supplied to a motor by a control circuit. This control is performed using a pressure switch that detects water pressure. The control circuit performs control that causes the motor to be turned on when the water pressure becomes equal to or less than a first set pressure value, and causes the motor to be turned off when the water pressure reaches at least a second set pressure value. In addition, when the water pressure has become equal to or less than the first set pressure value, at the pressure switch, the control circuit recognizes the amount of time (Tj1) until the water pressure exceeds the second set pressure value after the water pressure became equal to or less than the first set pressure value. In a case where this time exceeds a first time, it is determined that work has been performed using the cleaner, and thereafter, if there is not a case where after the motor was turned off the motor was turned on again after passing the first time, and in a case where a second time (T2) has elapsed, supply of current from a battery to the control circuit is automatically turned off. |
