Abstract
A hand-held high-pressure cleaning machine includes: a housing, having a handle for grasping; functional components, including a motor and a pump driven by the motor; and a liquid inlet, disposed on the housing and capable of being connected to an external water source by a water pipe. The hand-held high-pressure cleaning machine further includes an adapter suitable to be connected between the liquid inlet and a portable container, and is connected to the external water source by the water pipe or connected to the portable container by the adapter. In the present invention, the portable container configured to hold liquid is mounted to the hand-held high-pressure cleaning machine by using the adapter, so that it can be flexibly moved together with the hand-held high-pressure cleaning machine. The present invention further provides an adapter suitable to be connected between a portable container and a hand-held spraying device.
