How do I clean a Festool Dust Extractor - CT 36 E AC HD
Thought it best to seperate these two queries.

Hi all,

I've acquired a
Festool Dust Extractor - CT 36 E AC HD.

It runs well with plenty of suction.

It's been used for drywall.

It has a long life filter bag.

And and a few broke vent covers.

Any suggestions on how to clean?

Thanks in advance.
