In the present invention, in order to provide a high pressure washing device for which it is possible to mitigate an increase in cost, a high pressure washing device (10) is provided with a pump (12) that takes in and discharges a washing fluid, and a brushless motor (14) that drives the pump (12). The high pressure washing device is further provided with a control unit (15) that detects a load on the brushless motor (14) when driving the pump (12) and estimates the amount of washing fluid that the pump (12) has taken in on the basis of the detected load on the brushless motor (14), and the control unit (15) stops the brushless motor (14) if it is estimated that there is no more washing fluid to be taken in by the pump (12). |
