If you have a multitool XL, it automatically cleans the nozzle every time when a tool is getting picked or parked.

This is a remix in case you have other brushes that have a longer and thinner pin.

I ordered a pack of 10 from China. However, these have different dimensions when it comes to the fastening pin.
The diameter here is 2.89mm and the mounting pin length is 30mm long.

The original has a diameter of 3.15mm and a length of 22mm.

The Debris Bucked for the nozzle scrubber still fits nice.
