Cars attract their fair share of mud, dust, pet hair, leaves, and other things that contribute to an unclean interior. Despite the dirt, many people wait far too long to clean their vehicle, due in part to the difficulty of maneuvering a full-size vacuum's attachment in a car's cramped interior. Thankfully the Onshowy 12 Volt 75W Portable Handheld Auto Vacuum Cleaner eases the burden. A slim pivoting nozzle reaches the tiniest nooks and crannies of your car, while the 9.9-foot long cord plugs into the cigarette lighter. Keep the vacuum in your trunk for unexpected spills and regular upkeep. Available on Amazon; $26.99.
