I've only used the Eureka Hand-Held Vacuum 71B once but am disappointed. I had to try plugging it into several outlets before I found one that held the plug, which fit loosely in most outlets. The filter cup filled quickly (which I expected) however; it's not easy to empty as my dog's hair and debris affixed to the filter and required peeling off. Basically, emptying the dust filter over the garbage made a mess. I ended up using a tool from my large upright vacuum to clean off the filter. On the plus side, it collected a lot of dirt, hair, etc. from my staircase.
