Just look at the card, how he removes the 3-shku 80 squares. If you clean once a week, then he brings a full container (provided that the apartment is almost empty). If children + a dog are at home, then they can take out a container every day. Great buy, best value for money. By the way, I have an air filter with a mesh, and when tapping through it, the dust is badly shaken out. The filter cannot be washed. Once a week I dust out of it with an ordinary vacuum cleaner without a nozzle at low power - it works well, the filter is clean after that.
