Description

a cleaning device

technical field

The invention relates to a cleaning device.

Background technique

In actual life, we often encounter some difficult problems of cleaning floors, windows, etc. with existing cleaning utensils. According to our observation, we found that the traditional cleaning methods mainly have the disadvantages of labor-saving manual cleaning, incomplete cleaning of corner dust, brush heads need to be wetted with water, and high places are difficult to clean. For example: present household window cleaning equipment is generally a window cleaning brush and a double-sided glass cleaner. Among them, the window cleaning brush mainly uses double-sided glass scraping, one side is initially cleaned, and the other side is thoroughly cleaned. But this kind of window brush must be held by hand for a long time. On the one hand, it is more strenuous, and on the other hand, it cannot easily wipe the outer window glass. The use of the double-sided glass cleaner is to first dip the sponge on the glass wiper with water or cleaning solution, buckle the anti-drop ring with the thumb, and place the half with the anti-drop rope on the outside of the window glass. Press on the interior half of the window glass and gently slide to clean the glass. This kind of cleaner is small in size, very limited in use area, and cannot wipe high places. In addition, it uses magnets to absorb the inner and outer parts. In many cases, it cannot be completely adsorbed on the window glass, and it is easy to fall off. Finally, neither of these two cleaning methods can allow the cleaning head to freely switch between wet and dry while wiping the window.
