Do not consider buying if you need a vacuum cleaner and not an electric broom. It is good for crumbs in the kitchen and very small debris. More serious entrust the vacuum cleaner. Nuances - Battery degradation in a year! At first, it took a very long time to charge more than 4 hours for sure. Now it is less than an hour - accordingly, it works very little, and at the second speed it completely withers. So the battery capacity is almost gone. The new one costs about 4500 on Ali. You can replace the elements of 18560 - but this is clearly not for everyone. And in general, it often just discharges at the most unnecessary moment, I think that such things should always have two batteries, one will always be charged. Buy or not decide for yourself
