Kristi -- I have read that the Rainbow allows a lot of dirt to pass through
the water reservoir and back out into the building.  I believe Consumer
Reports and others have done research on this.  Instead, I would recommend
a Nilfisk, Miele, or other vacuum with a HEPA filter.  The current issue of
Consumer Reports compares 5 such vacuums.

Kristi --
This may not be possible with such short notice, but we use a Rainbow
vacuum to clean the floors in storage areas.  It has a water
reservoir that traps the dust and dirt so you can remove it from the
building.  They are not cheap - we paid almost $1200 several years
ago - but they are wonderful for keeping floors and walls clean without
introducing a bucket of mop water into your storage area.  Good luck.
