We have abandoned use of the Rainbow water vacuums which have poor
filtration and service records, in favor of vacuums with HEPA
filters.  In gallery maintenance, the Museum uses both the Nilfisk
GS 80 and the Wap SQ 550-21.  For most tasks, I like the Wap
(800-237-2368) better because it is quieter, has integral variable
speed and auto start features, and is half the price of the Nilfisk.
It is, however, bigger and heavier. You must buy the HEPA filter
separately ($160), though we are just now having Gore CleanStream
filters (800-758-6755) made to fit the Wap vacuums for about $35.
These are new filters on the market, are made of Teflon, have
excellent filtration specs, and are washable, which the HEPA filters
are not.
