What's your choice when sanding Granwood flooring? Mine is definitely the Bona DCS as it is easy to clean the filter out buy letting the DCS build up pressure and then blowing back the metal HEPA filter. I have used the Nilfisk CFM dust extractors and the filters on these machines just get clogged up quickly, and the method for clearing the filter is quite useless compared to the Bona DCS.

What's your option when it comes to floor sanding Granwood flooring?
