This article or topic likely discusses the types of vacuums commonly found at car wash facilities and explores the key differences between wet and dry vacuums designed for automotive use. 

Car wash vacuums are essential for maintaining the cleanliness of your vehicle, and they come in two primary types: wet vacuums and dry vacuums. 
 

Wet vacuums are designed to handle liquid spills and wet messes, making them ideal for cleaning up spills, removing mud, or handling interior detailing tasks.  

They often incorporate special features and attachments for efficiently handling liquids without damaging the vacuum's components. 

On the other hand, dry vacuums excel in picking up dry debris, dirt, dust, and other particles from the surfaces of your car.
