I bought it on the recommendation of a friend, she has been using it for more than two years, I have had it for half a year, recently, on our tip, relatives purchased the same model. I use nozzles, as far as my imagination suffices - I hate to carry dust over surfaces with a rag, so besides the floor, I process shelves and cabinets with different nozzles before wet cleaning. Also a decent amount of dust is collected from the sofa. The floor with an area of 45 m without carpets is cleaned at the maximum mode and charging is still left, I switch to medium or eco and continue cleaning the rest of the surfaces
