Wet/Dry Vacuums - What Product Category

I am hoping for some guidance on what product category wet/dry vacuums fall into. In the past we have called them "Vacuums", but the CRI (Carpet and Rug Institute) doesn't appear to certify wet/dry vacuums. It wasn't much of a problem because the properties had already met the 20% threshold with their other equipment so one or two wet/dry vacuums didn't hurt them. However, now we have projects that have been certified and are planning for recertification. If there is a need to purchase a wet/dry vacuum prior to the recertification it must meet sustainable criteria since 100% of equipment purchased during the Performance Period must comply.
