One of the most impressive vacuums in my collection is the Riccar 8900. The vacuum works well on both hard floors and carpets, and is on par with my Sebo X series. I have the bottom of the line model, so my vacuum can only clean floors unless the extension hose is added, but I can actually hear the air being sucked through the vacuum, in contrast to nearly every other clean air upright in my collection. If you add in all the parts you would want to replace on the vacuum (tools, cord hook) the price would come up to $40, $10 more than I paid for mine.
Here's a video of the Riccar against the Sebo.
