I beat the crap outa that vac today, took up 300 sf of tile, all the grout stuck on the floor. Rather than chisel off it I took my grinder to it with the dustie cover on it and hooked up to the vac. I re-used the disposable micro prefilter three times.
Then it ripped. Lucky I ordered 2 extras. It was like dustless in there. Worked pretty well for the extreme abuse I put it through.
Tomorrow I laminate the place.
