You do not get what you paid for. Received Floor One S3 Series as a gift. I feel bad for my daughter who paid for it. Expensive piece of crap. Wheels make black mark on tile. A professional tile cleaner advised to never push the cleaner forward. Only pull backwards. Keeps telling me to empty dirty water container and the dirty water cleaner is empty or not attached. Only good thing is that the solution has a good smell. DO NOT WASTE YOUR MONEY
