Cordless, compact, and powerful, the Black & Decker Lithium Ion Flex is a spring-cleaning savior. The bagless vac's 20-volt battery maintains crud-slurping suction for twice as long as the NiCad-powered model and holds a charge for 18 months. Its flexible hose reaches up to four feet away, yet coils around the base to save space. [$150; platinumseries.com]
