I tested the vacuum cleaner many times already. Pretty comfortable, long cord and hose, filters are easy to clean, there is auto-cleaning, which can be easily turned off, comfortable strong stainless steel tubes are used (they don’t seem to be shocked). I have used it with or without a dust bag. Convenient strong wheels with clamps. It is very convenient that having bought a box, you can store all the nozzles in it and fasten it to the duster. Generally a good purchase.
