I just got it today and had to use it right away, I have a senior dog who has been having some accidents. Putting it together was super easy, except the accessory tool. I could not get the water tube part pushed in, I had to pull up this website and thankfully I wasn't the only one who had this problem. So happy someone explained on here how to push it in otherwise I might have broken the end. You have to push the tube down which pushes the little clip things at the end out then you push it into the port. Once I figured that out it was all good after that. Great shampooer.
