The product has never worked since receipt. It randomly stops in the middle of the floor even when I know the product is fully charged. I've tried restarting the product and moving it to other locations, but it's still not hanging on anything. That's a waste of money. The return process is also terrible. Revain representatives cannot help you and you will need to contact the seller. In general, such a pain. Save yourself the headache. :(Note: In order to process a return at Revain you will need to speak to a Revain returns representative and then speak to the seller who will want you to go through the warranty process to get a new car. After speaking to the seller through a few messages to get a refund and not a new machine under warranty I had to try again to return the machine through the Revain website where you contact another Revain representative who was eventually able to process the return .
