I have a construction guy who wants me to clean the concrete in this warehouse he is building. It's 70,000 square feet. Problem is it has no drains and it lays level so that the water will not pool well enough to use a boom vaccuum system. I have looked at buying a Steel Eagle flat surface/vaccuum system and I was wondering if any of you had ever used one of these and if it works. Or if you have some other idea that is better than a squeegee.
