Seems to me that the wet vacs avaliable go from about $100.00 then jump to about$400.00. Problem with the ($120.00)Rigid and Sears shop/ wet vacs is that the brittle plastic head breaks. Sometimes on the first night. Catching the grout areas on a kitchen floor.Additionally they put a removable squeege in the head of the vac which snaps, or gets filled up with debris. Piece of crap. The head doesnt work without it. Sears had a good wet head years ago but stopped making it. Now the alternative is a real expensive vac. Rigid has the same inferior wet heads. The hose size is 2 1/2 which is not standard. Metal wet vac heads are 2 inch. Not interchangable. Probably sized that way intentionally. Anyone know how to get the 2 in wet head on the 2 1/2 in wand? Or a reasonably priced wet vac? We have tried the adapters but they too are brittle plastic.
