Vacuum cleaner with very strong suction. The noise, of course, is not lower than other similar ones. An advantage is the automatic filter cleaning system. It also has two operating modes. 1. Filter and filter cover where the ash collects in the metal container. 2. Filter and use of a reusable bag where the ash collects. A disadvantage may be the plastic instead of metal flexible hose. In summary, it is a very good and reliable vacuum cleaner.
