I didn’t think that there was so much dust at home, fine dust like flour - he keeps it, small pile from the carpet - two mediocre carpets and the container is full. Treshka 67 meters, on the first floor (the windows are closed, winter) - if you vacuum every other day, the container will be filled. With a longer cleaning interval, the container will be filled twice. I advise you to buy, you will not regret
