Action

In order to supply the cleaning liquid from the surface cleaning apparatus 1 toward the surface to be cleaned, the user operates the supply switch 40 so that the supply pump 5 is driven. By driving the supply pump 5, the pump pressure indicating the pressure of the supply pump 5 increases. In the embodiment, the main body casing 2 houses the pressure switch 44 for suppressing excessive rise of the pump pressure. The pressure switch 44 is disposed behind the supply pump 5. After the supply pump 5 is started by the operation of the supply switch 40, if the pump pressure reaches a predetermined value, the drive of the supply pump 5 is stopped by the pressure switch 4. If the pump pressure is smaller than the predetermined value, the driving of the supply pump 5 is restarted.

When the trigger lever 45 provided to the nozzle 38 is operated in a state where the pump pressure is increased, the cleaning liquid flows out from the supply port 34 of the supply tube 7. After the cleaning liquid flowing out from the supply port 34 flows through the supply hose 36, the cleaning liquid is supplied from the nozzle supply port of the nozzle 38 toward the surface of the cleaning object. Further, by releasing the operation of the trigger lever 45, or by operating the supply switch 40, stopping: and supplying the cleaning liquid from the nozzle supply port of the nozzle 38 toward the surface of the cleaning object.

In order to recover the cleaning liquid present on the surface of the cleaning object by the surface cleaning apparatus 1, the user operates the suction switch 41 so that the suction motor 6 is driven. The suction motor 6 is driven to collect the cleaning liquid present on the surface of the cleaning object from the nozzle collection port of the nozzle 38. Further, by operating the attraction switch 41, stopping: recovery of the cleaning liquid from the nozzle recovery port of the nozzle 38.
