FAQs

What is a wet/dry vacuum, and how is it different from a regular vacuum?

A wet/dry vacuum, also called a shop vacuum, is built to pick up both liquids and dry debris, something a standard household vacuum can't safely do. It uses a sealed motor and a wet-safe filter or foam sleeve designed to handle spills, fine dust, and debris without damaging the motor.

Can a wet/dry vacuum actually pick up standing water?

Yes, that's one of its core functions. Many models include a float shutoff that stops suction automatically once the tank is full, preventing overflow, though it's worth checking your specific model to confirm this feature.

How much suction, Peak HP or CFM, do I actually need?

Peak HP (Peak Horsepower) is an industry standard measurement that represents a vacuum's maximum motor output under ideal testing conditions. Because those conditions don't occur during everyday use, Peak HP should be used as a general comparison between similar wet dry vacuums rather than as a measure of real world cleaning performance.

For a better understanding of a vacuum's cleaning power, look at these key performance specifications:

  • CFM (Cubic Feet per Minute): Measures airflow. Higher CFM helps move larger amounts of debris more efficiently.
  • Water Lift: Measures suction strength. Higher water lift provides greater lifting power for heavier debris and liquids.
  • Air Watts: Combines airflow and suction into a single performance rating, making it one of the best indicators of overall vacuum power.

When comparing wet dry vacuums, consider CFM, water lift, and air watts together to get the clearest picture of real world performance.

How do I clean or maintain the filter on a wet/dry vac?

It depends on the filter type. Cartridge filters made with standard, fine dust, or HEPA material can often be tapped out or lightly brushed to remove dust. Filters made with PET material are washable and need to be fully dry before reuse. When a filter becomes too dirty or the vacuum is losing suction, replacing the filter with a new one is recommended. Check the manual for your specific model before cleaning any filter.

What size tank should I get with a wet/dry vac?

Smaller tanks, 2.5 to 5 gallons, are easier to carry and store but need emptying more often. Larger 8 to 16-gallon tanks handle bigger jobs with less frequent emptying, but are heavier and bulkier to move.
