Nu-Star is a Shakopee-based company, established in 1963, originally as a manufacturer and marketer of car wash equipment. The company has since added several other product lines, which include Power Pusher (battery-powered tugs to pull wheeled loads up to 100 tons in weight), Wet Noses Clean Paws (a line of self-serve dog-washes) and Sky Pro (self-cleaning, automated window-washing equipment).
