This is an add-on toilet bubble cleaning machine. I saw it on TV and was impressed, so I bought it, but I ended up not using it and it's been stored in a storage shelf. I opened it to list it for sale, but it's new and unused, and all the parts are included. The fixing sheet was stuck to the instruction manual, so there's some paper stuck to that part, but it's on the edge, so I think it can be used without any problems. Washlet
