The dealer that Sebo recommended wanted to get me to buy a new brush roll for it. The dealer did not find anything else wrong, $10 later. The dealer I took it to, I would not visit again he’s rather shady in his business. He told me that the X4 is not meant for hardfloors, he said the squeegee on the back is for carpet!
After getting the call from the “shady dealer”, I called Sebo. Sebo said they want to try and have me calibrate it over the phone, or it may indeed be the brush roll. I got a bit testy and over the phone, and the guy said Sebo may send a free brush roll after trouble shooting, but it’s not definite.
After calling Sebo, I contacted my salesman at the dealer I like to deal with. He is sending me a new brush roll for free to see if it works, he said that he had some x8s with this problem. The good dealer that I use deserves the recognition.
If you ever need parts or a machine I recommend contacting Aaron at Classic Vacuum, North Canton Ohio. Every interaction with him has been great.
