Shop Vac Motor Burning Smell: Causes And Troubleshooting

When a shop vac sucks up water, the motor may emit a burning smell due to several reasons. Electrical damage can occur if water bypasses the wet/dry filter and enters the motor housing. Common motor issues include waterlogged bearings, worn brushes, or an overheating armature. To avoid motor damage, ensure proper electrical connections, use the wet/dry filter correctly, avoid excessive water intake, and perform regular maintenance. If you encounter a burning smell, unplug the vacuum, check for water damage, and refer to troubleshooting guides for further diagnosis and repair.
