Eureka 71B Hand Held Vacuum
At 5 pounds the Eureka 71B weighs a bit more than other models on this list but conveniently keeps its stretch hose and crevice tool onboard while featuring a carpeted stairs tool called the Riser Visor. This plastic cover can be flipped up or kept down depending on the surface you're trying to clean allowing you to direct the suction to clean both horizontal and vertical surfaces.
5.5 amps of power makes this unit suitable for a variety of uses, whether in the house or car with one motor powering the revolving brush (which can be switched on or off) while a second motor provides suction power. The 20 foot power cord offers a good amount of mobility while the bag-less dust cup and filter are simple to clean.
