A wet-dry vacuum that clogs on wood chips in the first hour is not a workshop tool, it is a return waiting to happen. The real difference between a $50 shop vac and a $150 one comes down to hose diameter, tank capacity, and whether the filter can actually handle fine dust without clogging every 20 minutes. For budget shoppers, the DEWALT DXV20P 20-Gallon Shop Vacuum delivers the tank size and hose diameter that keep clogs from killing your weekend, while the Bissell CrossWave HydroSteam Pet Pro offers a completely different approach for shoppers who need wet cleaning on indoor hard floors instead of garage cleanup.
