I don't know any other sand paper manufacturer in finland besídes of
mirka. I like mirka sandpapers a lot but it seems that I have to clean
them (I use a stiff brush) quite often.

seismo malm (from finland)

Clean what, the electric sander pad or the sand paper? If you have to clean
the sand paper often you should switch to an "Open Coat" type sand paper.
If you have to clean the electric sander pad often, thanks for the warning.

Not from Mirka adhesives ime, if that's what you mean. Sounds like he's
got a problem w/ varnish or sap or other similar problem. As you say,
open coat will help. I've not seen any particular tendency to clog
excessively w/ Mirka papers, and we've been through a tremendous amount
over the last 18 months or so.
