I purchased a 14,000 square foot warehouse that was completely coated from top to bottom in nearly an inch of sawdust from the previous owner. The Dura '17 cut the final step of cleaning the floors in half by not having to sweep first (however most of the dust had been blown out of the building prior to running the floor scrubber to avoid clogging it). This scrubber did a fantastic job and it took me about a little over an hour to do all 14,000 square feet. The only minor con I would mention is that it does not allow for 360 degree turns, so it takes some time to map out the best path given this limitation. You constantly have to work around the cord as well, but I'm sure you're likely to run into this with any non-battery operated floor scrubber.
