I use my shop-vac for everything, including liquids. Did not realize until now that I'm supposed to prep it differently for liquid pickup than for dry pickup. But the instructions are very unclear. Standard cartridge filter by itself gets kind of torn and ugly after sucking on water.
Am I supposed to remove that cartridge filter entirely to suck water? As in, no filter? Am I supposed to leave it there but put a foam sleeve over it? What does the sleeve do? The cartridge filter, if left there under the foam sleeve, is still going to get pretty wet and ugly.
What is the difference between a "reusable dry filter" and the cartridge filter? I reuse that cartridge filter routinely. The manual tells me to put said "reusable dry filter" over the foam sleeve, which I guess is over the cartridge filter. Three filters???
