A very powerful cleaning tool that is convenient and easy to use! This gets up super fine dust that a broom could never get up. Lightweight so you can easily use it for  stairs, window sills and ceiling fans. 
The battery life is fairly close to what they claim. I was able to use this on low power with a few minutes on medium for a full 40 minutes. When I had it on mostly medium power with a few minutes on high it went for 25 minutes. Low power actually works very effectively so if you have a lot to clean it is best to keep it on low for the max battery life. A bit disappointed that it does not come with the wet and reusable pads or the combination tool. I’m including a pic of the manual with the things not included crossed out. I docked this one star for that reason and value wise I’d think it should have that and an extra battery. Otherwise, this is really an extraordinary cleaning machine!
