Yes l had one but found its ability limited when compared to compressed air blasters. The water was messy and had problems with the moisture feeding into the Venturi and blocking the sand flow. Then if I managed to get something steel back to raw metal it would surface rust instantly. I ended up modifying a sandblaster Venturi and attached it to a different more powerful pressure cleaner but I ended up having the same blocking problem. I guess it depends on what your trying to achieve with it to whether it's worth it or not.
