This vacuum cleaner changed our lives nonstop dragging a golden retriever and now a crawling baby. The battery is sufficient to vacuum around 1,500 square meters quickly. UPDATE: After three months of normal use (2-3 times a week) the rubber cracked out of nowhere. It was never hit or dropped (I mean we paid close to $400 for it). I called Dyson and the rep said the warranty doesn't cover wear and tear but he will make an exception and send me a new dirt deposit. While I appreciate they sending a new one, I don't appreciate it pretending to be a favor. Only my husband and I use it and I know neither of us did anything to cause all of these cracks.
