A proper vacuum cleaner is the foundation of any interior detail. Whether you're picking up dry dust, sand, and crumbs or extracting wet stains and shampoo residue, the machine determines how fast and thorough the job gets done.

Wet/dry vacuums are the standard in detailing. They handle liquids without damage, which you should never attempt with a regular vacuum. Pay attention to motor power, filter class, and whether the unit supports blowing mode for compressed air work.
