My robovac 30 makes nasty grinding noises when the front brushes hit something that stops them rotating (like the edge of a mat, some furniture, etc). They function normally aside from that.
It sounds like the gears inside the unit that drive these are a bit stripped, and so they skip teeth when the brushes are stalled (and over time I’m expecting they will stop working entirely given the nasty noise).
It’s a couple of years old, so not expecting that this is a warranty issue, but whilst I can find new brushes, new filters and even new drive wheels on eBay, I can’t find any spares related to the whisker brush drivetrain.
Anyone know where I might find these spares?
