Hi,
I bought the Robovac at the end of February 2018 and have been using it about 3 times a week roughly. Everything has been great even though cleaning patterns seem a bit chaotic. Unfortunately last week I noticed that the rotating brush is making a really bad and loud noise. My suspicion is that there is some sort of bearing inside the brush that failed. The question I have is: should that really fail in just over 3 months of quite light use? New brush costs around 13 Euros and I do not thing changing it every 3 months is a viable option.
