I use 3 weeks. Apartment 47m2 - including furniture, removes 37 (according to the application) and a long-haired cat. I run every other day at maximum suction and max. water (after wetting a cloth for wet cleaning). Water is just enough. The charge remains about 17%. Dust container, every 2 days about a quarter full of compressed wool. An impressive woolen sausage is obtained. The cat does not shy away like from an ordinary vacuum cleaner, it just does not like this unit.
