Firstly, I rarely post a review, although I do my best (seriously, coffins are more readily available on Amazon). This vacuum cleaner is the holy grail of all cordless vacuum cleaners. Honestly, you can't love cleaning gadgets as much as I do these. But unfortunately they exist! It has one downside: the battery. You might have 40 minutes in normal mode, but if you're like me you want to go all out with maximum performance. In this case, the battery lasts about 20 minutes. It's not a big problem
