Let me tell you about my cleaning system. I don’t let the vacuum cleaner clean the whole apartment at once, but in the rooms, after raising the chairs (if you clean using this system, it goes through the room 2 times). I have a dog and two cats (wool is where to come from), so in places especially visited by all family members (entrance hall, kitchen), I sometimes run the vacuum cleaner a second time additionally (after the second time, the cleanliness is perfect). And it really saves time, which is very valuable to me.
