There have been no complaints about the level of cleanliness achieved; however, it is problematic as the brush moves in only one direction on the carpet; you find it difficult to move it along the return line since it clings to the carpet and bounces. Extremely difficult and inconvenient to care for. The container is made up of a number of premade plastic parts; in order to use it, you will need to play the role of the constructor each time: locate the grooves, twist and snap the parts together, and insert the detachable filter. The song about washing it is a different one! The container may be broken down into numerous separate pieces; however, there are two covers at the bottom and top that cannot be removed. These covers press cruelly on your fingers whenever you make an unusual movement while you are attempting to wash them. In addition, I have a constant worry that they will become detached since they are extremely fragile. One of the components that should be contained within the container perpetually dislodges itself, despite my best efforts to secure it. The assembly instructions do not provide any diagrams. It is difficult to secure the lid since the second filter frequently dislodges itself from the wheel. Be careful if you decide to purchase this technological marvel; when putting it together, pay attention to the instructions for shutting and opening it; if you get the two confused, you will need to take it to a service center to have it opened. I really wanted to get the same thing for my mother, but I realized that it is not appropriate for someone of her age. Made to be low-quality and dripping with moisture for a German vacuum cleaner. It was impossible to save money on the tiny items, like covers and latches. After putting this buy through its paces for a month, I still do not feel satisfied with it. Perhaps I do not understand how to get along with modern technology. I put it to use once every week. I was looking to purchase a useful appliance that would be easy to use frequently. Disappointment.
