My X4 has suddenly become hard to push, not sure if my brush is bad or a problem with the height system. My X4 is 8 months old, I don’t see how the brush (blue) could be bad. I just used it, and it was very difficult to push, I also noticed that the base was hotter than normal, my bag is not full. Does anyone have a suggestion? I will be contacting Sebo and my dealer next.
