This dust collector was entirely unsatisfactory and has been replaced. It now sits all alone outside and is not being used and nobody interested in buying it used.1. Very hard to clean the filter.2. Very fine dust like from a drum or wide belt sander plugs it up almost instantly.3. lid is heavy and inconvenient and needs a very tall can to keep from sucking stuff from the trash can into the filter.4. Not sure I ever got even near 650 cfm. Doesn't even work on one machine very well.5. Usual crappy tech support from Jet, Performax, Delta ETC. You know when they all are under one corporation, tech support will go down the tubes.5. Reccomendation: buy something more powerful like a cyclone type DC.
