I have returned my RO5255 to the manufacturer after twice use. After all, there is in my case a 30-day money-back guarantee. Along with the hard starch already described negative falls on the telescopic tube that not raus without Hakeln and leaves pure return. An exchange of the telescopic tube has already been done, because nothing happened more and the second is not really better, I fear that even this gets stuck at some point. Hence my decision: return :(
