Worth your money. I recommend Some pros: Works one hundred percent. Filter sensitive. It is used in a private house on 2 floors, coupled with a robot vacuum cleaner. For maintenance cleaning. Easy. Inexpensive replacement filters. Easy to clean. Traction is good for tiles, linoleum, laminate. (did not test for carpets). Its cons: Once "died", cleaned the filter . the vacuum cleaner came to life. Small dust container. The container is about the size of a hand-held vacuum cleaner for a car. Short cable, solved by an extension cable.
