I was looking for one vacuum that was light but also strong enough for carpet and pet hair and light enough to use daily for my wood floors. It was also important that it be cordless. The included larger battery is great and probably an industry leaders. I bought a different brand first and was lucky to have it last 10 minutes before charging. I am not sure if the hoover battery meets the claims it makes but it does last a really good amount of time and I am happy with the product. You can set it at three different suction levels which will also allow the battery to last longer if needed.
