To prolong the life of the dust filter, they put a nylon sock on it. At first I thought the , but it helps. Pros: Sufficiently powerful suction force, although the vacuum cleaner looks modest. Due to its light weight and maneuverability, even a 9-year-old child can cope with dry cleaning of the apartment. Removable handle and additional nozzles allow you to clean the car interior. The filter can be washed under running water. It is designed in such a way that it is able to stand upright on its own. Doesn't take up much storage space. Cons: Yes, I liked everything, for such a price, just a find. Well, although, I would note the fact that the foot of the main nozzle does not have a swivel joint, so the nozzle is movable only in one plane.
