I used it constantly buying to replace the usual one and here was my mistake. A year later, he began to often issue a filter error, although everything is in order with the filter and it is clean, I constantly monitored this, and after another 3 months it simply stopped turning on. You press the button, the battery light comes on and nothing. Disposable vacuum cleaner for 1 year. By the way, a friend of mine, on my own advice, who bought it, had exactly the same breakdown. After reading on the Internet, I realized that we are not alone. I don’t know why you all praise him so much here, this is an ordinary pvlesos, with the usual capabilities and still unjustifiably expensive in relation to competitors. I do not advise you to buy, buy better than Xiaomi, the quality is the same, only there is no base on the wall, this is the only negative. And I'll probably take it to repair it or in the trash, I haven't decided yet.
