Really liked this out of the box for quick cleanups, but after 2 weeks I noticed if I wanted to do more than just a spot clean, the battery only lasts about 10 minutes. That's why I bought the stupid thing in the first place because it runs on battery, don't have to worry about the cord constantly.. I also clean other people's houses from time to time, and was excited not to have to drag my heavy vacuum with me. Really bummed this wasn't what it said it was! False advertising
