Why vacuums alone fail
Short guard hairs weave into carpet loops; suction can't pull them out without first loosening them.
DIY method
Drag a rubber brush or damp rubber glove in short strokes to ball up hair, then vacuum. Repeat in cross directions.
Professional method
Detailers use drill-mounted brushes, pet-hair stones and air tools, then extract and deodorize.
Prevention
Hammock seat covers and cargo liners save hours of cleanup.
