I've owned the corded version for a couple years. I have an entire house of tile, so I'm always looking to make it easier. I have used this twice and find the battery life to be sufficient for the rooms I am working in at the time. LOVE not having a cord. The only negative I noticed was that the cordless one pulls or is a bit harder to control than the corded and is a bit heavier in your hand. Not a huge deal, but I am starting to get arthritis in my hands and wrists, so I wish they'd find a way to fix this. I also wish they'd drop the price on the pads as they never look good again once you use them and I like to change them often. I recommend this for sure though.
