When a user sets water power using a water power adjustment switch in a remote control device, a controller controls the period of pressure fluctuations, the width of pressure fluctuations, and the central pressure of the discharge pressure of a pump on the basis of a signal transmitted by radio from the remote control device. When the user sets the divergent angle of washing water using a washing area adjustment switch in the remote control device, the controller controls the divergent angle of the washing water sprayed from a posterior nozzle on the basis of the signal transmitted by radio from the remote control device. Consequently, the washing water supplied to a side surface of a cylindrical swirl chamber from a first flow path in the posterior nozzle is sprayed from a spray hole as dispersed spiral flow, and the washing water supplied to a lower part of the cylindrical swirl chamber from a second flow path in the posterior nozzle is sprayed from the spray hole as linear flow. |
