The quality is very good, it is easy to use, the overall texture is not light, it is easy to store, and the suction is quite large. I have been using it to clean the car during this period. I feel that things are worthy of praise. It is clean after a few minutes of inhalation. The suction power is sufficient for daily use. It is easier to clean with water. Before a lot of fine dust was not taken care of, it is now easy to take care of.
