Can the property wash the floor with a high-pressure water gun at will?

You can't. The water pressure of the high-pressure water gun is very high. If it is used improperly or necessary measures are not taken, it will cause damage to facilities and buildings such as the ground, walls and water pipes. And if you don't pay attention to the surrounding environment and people, it will cause accidental injuries. So don't wash the floor with a high-pressure water gun at will.
