I advise you to take out the roller, after cleaning and self-cleaning it remains damp and needs to be dried in order to avoid unpleasant odors. With its pros: Good, really washing vacuum cleaner. Ideal for regular wet cleaning. When I took it, I was afraid of a problem with the water supply button, as many wrote that it was breaking. In the end, everything is fine, half a year - everything works. Powerful battery, there is always more than 2/3 of the charge left after cleaning. Cons below: The vacuum cleaner has a self-cleaning function, but you still need to periodically wash the plastic part where the roller is inserted - dirt accumulates there. Otherwise, you will smear this dirt all over the house. Dried dirt does not wash off very well, it is easier to walk separately through contaminated places later.
