I ordered a robot vacuum cleaner, more time for myself and the child. Yes, and the child is always running around, chewing something, crumbs on the floor, even with a rag go after him. After acquiring a miracle technology, life became easier. I built a map of the apartment, and set to work. Washes well, too. Haven't seen any streaks in a couple of months of use. Copes with its function with a bang.
