How Do I clean the side wheels?

On my L50

The two wheels on the sides. The ones that drive it. They are starting to get a lot of junk in them. Much like the front wheel does. I  can pull the front wheel out and clean it. However, I cant clean the two side wheels. Ive tried pulling the sruff out with tweasers and needle nosed plires. But I havent had any luck. Do I have to take this thing apart?

Box knife , cut on the hairs and pull em out 😬

Yes, typically with these there’s no other way to get the hair out unless you disassemble them. There’s just no way to prevent it unfortunately.
