It is recommended to run the WetVac on the stubborn stains for a few seconds during mopping, so the rolling brush can repeatedly clean the same stubborn stains, which is more efficient than mopping the stubborn stains back and forth.
 

If you need to clean a specific area several times, it is recommended to clean that specific area by continuously moving the WetVac in a forward direction instead of moving the WetVac forward and backward. This is due to the forward cleaning effect is better than the backward cleaning effect.

Additionally, it is suggested to add the eufy cleaning solution to the clean water tank. Please add a maximum of two bottle caps of the eufy cleaning solution to a full tank of clean water.
