My i9 is making a loud whirring noise and continues the same when cleaning. There is nothing stuck in the wheels or in the bin. Can anyone please advise what could be the problem?
My purei9 has been making unusual loud noise just 4 months of usage. That noise sound like rapid loose flap or motor vibrations. I don't know the reason but I did not bother to send for repair since by default it was already very loud and I leave it to handle a small close door room.
