The car nozzle is an attachment for shop vacuums designed for thorough cleaning of vehicles. It’s among the few accessories for wet/dry vacuums that effectively clean seats, floor mats, and upholstery. The 2-1/2-inch diameter of these attachments enables them to gather larger debris and maximize airflow. It is compatible with most shop vacuum hoses or wands that have a 2-1/2-inch diameter collar. Additionally, in a pinch, the car nozzle can function as a dual-purpose tool when used as a blower nozzle; simply connect it to extension wands with the hose plugged into the wet vacuum’s exhaust port to clear debris from your garage or driveway.
