Frequently Asked Questions
You should never vacuum flammable liquids like gasoline, hot ashes, toxic materials like asbestos, or extremely sharp objects with a wet/dry vac, as these can cause fires, explosions, health hazards, or damage the machine.
When choosing a wet/dry vacuum, the most important factors to consider are its suction power, tank capacity, filtration system, and overall portability, all tailored to your specific cleaning needs.
To properly use a wet-dry vacuum, ensure you have the correct filter installed for either dry debris (cartridge or bag filter) or liquids (foam sleeve), empty the tank regularly, and never attempt to vacuum flammable or hazardous materials.
A wet/dry vacuum typically stops suctioning due to a blockage in the hose or attachments, a clogged or incorrect filter, a full tank or bag, or air leaks in the system.
Yes, you must remove the dry-use paper filter when vacuuming water, as the liquid will damage the paper filter and can harm the motor. Instead of the paper filter, you should typically install a separate foam sleeve or "wet filter," which is designed to handle liquids while still protecting the motor. Always consult your specific vacuum's manual to confirm the correct procedure and recommended filter type for wet applications.
The two holes on a wet/dry vacuum are the intake port for vacuuming up debris and the exhaust port which converts the machine into a powerful blower when the hose is attached to it.
