For most car interiors, a vacuum in the 80–120 AW (Air Watts) range is the sweet spot — enough to pull crumbs from seat crevices and pet hair from floor mats without being overkill. If you’re just doing quick crumb patrol, 60–80 AW will do; if you’ve got kids, dogs, and sandy floor mats, push toward 100–150 AW. Below 50 AW is basically a novelty — it’ll move loose dust but choke on anything embedded.
