As you might expect, a wet and dry vacuum cleaner is designed to handle both your typical dust and crumby messes, as well as liquid spills. Unlike your standard upright vacuum cleaner, these can often be used indoors and outdoors, with a separate motor to prevent any electrical problems when sucking up water. A wet and dry vacuum will have a higher suction power than your typical household vacuum, and is often used in construction and DIY settings, too.
