Why did my Shop-Vac® wet dry vac lose suction?

The most common causes of loss of suction are dirty filters or a clog in the hose. To troubleshoot, remove the hose from the vacuum, place your hand at the opening of the tank inlet and turn the vac on.

If you feel suction at the inlet, the issue is with your hose or accessories. Check your hose and accessories for a clog. If no clogs are found, check the hose for a hole or crack - even a small crack can cause a loss of suction. If a crack or hole is found, replace the hose.

If you do not feel suction at the inlet, turn the vacuum off and unplug from the outlet. Follow the steps in the user manual that came with the vac to clean the filter. Check the filter for rips or tears; replace with a new filter if any are found. Empty the tank or if you are using a collection bag replace it if it’s full. Make sure the filters are properly installed then secure the housing to the tank. Plug the cord into the outlet, turn the unit on and place your hand at the tank inlet to check for suction. If you still do not feel suction at the inlet, turn the vacuum off and unplug from the outlet. Check the tank for any cracks and make sure the drain cap, if applicable, is secured to the tank.
