Although they are perfectly fine when you are sucking up dust and dirt, when picking up liquid, you want to remove them. However, foam filters are okay, and you can just leave them on. Additionally, make sure to give the instruction manual a thorough read before you start working. It contains a lot of information, and you might even learn something about your particular machine that you did not know before. Furthermore, make sure you are using a shop vac to only pick up non-flammable liquids like water or soda. Flammable liquids like kerosine or petroleum can cause severe problems and may even result in an explosion. You might also want to remove any bags over the bucket of your shop vac. Since you are picking up liquid, it is easier to dispose of it when it is stored neatly in the bucket of your shop vac. If the spill is on a hard surface such as the floor, you can use the shop vac normally. However, for carpets, you might need a different type of attachment on the hose of your machine. Typically, most shop vacs come with this type of attachment with your purchase. But if you do not have this accessory, you need to consider buying an aftermarket one.
