As soon as I got my robot vacuum in the mail, I opened it up and turned it on to see what it could do. Thankfully, it had a little battery life to it. In just 5 minutes, it had picked up so much dirt and dog hair. I was almost embarrassed since I had just vacuumed the day prior. This little guy is quick and rarely gets stuck. The one thing I didn't like is that it did get stuck trying to go up on an area rug while on the kitchen floor. That would not stop me from buying this vacuum again! I even named it, Dobby! I am super pleased with Dobby and recommend this brand to all!
