Bought this to replace a worn out 20 year old Mighty Mite.  I think too much stuff had gone through the impeller, just wouldn't suck hard enough anymore.  Was concerned buying the same brand but this baby does the job, really sucks,  and they've improved the design in several ways like the larger wheels.  Good set of accessores.  Great value.  All I can say is,,, "This thing sucks --- I Love it!"
