Ok, first of all. I'm not invested in any one tool system yet, I have tools from a variety of colors. As my remodeling business picks up, my standard rigid wet/dry vac isn't cutting it for dust removal in my clients home. I'm seriously considering the CT-Midi for dedicated dust extraction. But I am also doing more concrete work so would a DE like the Bosch VAC090AH which is both osha silica dust certified and the EPA RRP certified be better suited for my needs? I really like the whole festool system concept and plan on picking up at least 1 festool sander.
