Very powerful vacuum cleaner, more powerful than my construction vacuum cleaner at 1250 watts. At the same time, it is quieter than a construction one. Among the shortcomings is not the tank itself and its volume, but the fact that the dust partially passes by the tank and is sucked into the cyclone. This clogs up the filter pretty quickly. When there is a lot of dust (in the filter), you will hear (just hear, it will work quieter), the power will also drop slightly.
