- Clogged filters: Debris can clog the filter faster, further reducing suction.
To avoid these issues, empty the tank regularly. This ensures your shop vac performs at its best.
| Action | Frequency |
|---|---|
| Empty the tank | After every use or when half full |
| Check the filter | Before each use |
| Clean the filter | Once a month or when dirty |
