Just thought I would give a word of caution. I have had a Shop-vac Pro, model QPL625 18 Gal for a number of years. The on/off switch went bad the other day. A call to Shop-vac revealed that the on/off switch is not a replaceable part. You have to replace the entire power unit. I don't know how many models have this requirement, but this model does. It doesn't make any sense at all to have to replace a perfectly good power unit because of a bad switch. I know that I will never buy a Shop-vac product again and will never recommend Shop-vac to anyone.
