The Eureka Hand-Held Vacuum, 71B
This is the product description from Amazon:
Hand-held but very powerful, this Eureka model eliminates the hassle of lugging around a full-size vacuum for cleaning car upholstery, sofas, and carpeted stairs.
A 20-foot long cord which can also be wrapped around for storage purposes, provides good reach, as does the deluxe hose that stretches to three times its length.
With the crevice tool on the end of the hose, this vacuum reaches into all kinds of tight places. Its high power suction is driven by two motors.
One motor provides power to the revolving brush and the other for suction. The 5.5 amp power allows this vacuum to clean deeply.
It is just one of those really useful things that you just don’t want to be without!
Just so convenient to clean out the car – you know how messy that gets when you have kids!
