It has been almost a year since I bought a Dyson vaccuum and it is still working great. James Dyson claims in his commercials that his vaccuums will never lose suction and it is true. The unit is also bagless and very easy to empty. You don't get dirty or dusty at all when you empty it. I couldn't believe the stuff it sucked out of my carpets the first time I used it. His products are pricey but worth every penny.
