I figured it was time to write a quick review after three years of regular use.  This Eureka Mighty Mite is a bit like the little engine that could - could clean up, could be easily carried, could make leaves blown into the garage go away, and could dispose of little balls of dust or dog hair.  Not only 'could' but 'does' quite effectively.  As my age progresses, it is getting more difficult to get certain household appliances from one room to another.  Not so with this little Eureka - small enough to store under a work bench in the garage, light enough to carry up the stairs.  Two areas of concern keep it from a five star rating:  it does not do a good job on dog hair on auto carpet.  It's larger cousin has to handle that job.  Additionally, the attachment hose jams up quite often.  That's easily fixed by running a long rod (like a skewer) through the hose to loosen up the debris.  Then it will usually just pick up where it left off.  Be sure not to go bonkers with the unjamming process - you don't want to poke a hole through the hose.  The main question:  does it do the job effectively?  Answer:  an absolute yes.
