I don't need to clean up much pet hair.  Was looking for a vac to replace ones I have had over the years made by Hoover - a small, commercial, light weight unit that I can carry over my shoulder.  While looking for the next version of that machine on Amazon, I found this one by Eureka.  It's small and light weight so I can carry on my shoulder (with a strap from the Hoover).  It has lots of power, gets under and behind things easily, cleans out in a snap and stores in almost no space.  In fact, the only thing this machine lacks that I liked on the much-more expensive Hoover is the length of the power cord.  With the Hoover I could do the whole house moving the cord once.  With this I move the plug twice.  Otherwise, I am completely satisfied with its operation.
