I'm surprised you folks have yet to mention the new Bissell Healthy Home upright being a viable competitor to the Dyson range.  Best Buy now has them for $299, and from what I saw in person, it is a pretty strong competitor, if not, a solid alternative to the DC07 and DC14.  As being essentially a rebadged Samsung, it is of very high build quality, with an effective emulation of Dyson Root Cyclone technology, as well as many other features that make this upright a value leader in the segment.  If LG is the first company to effectively duplicate Root Cyclone technology, then Samsung/Bissell is certainly the second.  With all of the filth I picked up off the carpet in the aisle way, no dust was seen on the prefilter.  
 
However, that may differ from actual in-home use.  But with a dual motor system, a competent brushroll, one touch emptying, and an on-board turbobrush, I see the Bissell being a more worthy competitor than the Infinity, although they deserve credit for launching a good offering for its price segment, even if the cyclonic system is not as efficient.  However, there is a big drawback for the Bissell, for it is a porker.  Tipping the scales at 24.5 lbs, it is no lightweight, but the large rear wheels made it easier to maneuver for its weight.  Now I'm waiting to see how the new Eureka machine will turn out to be when it comes out.

The Bissells came out about Friday.  I have to say that I am amazed at this machine(Healthy Home).  When you first lift the vacuum by the carrying handle, you notice that it feels more durable.  The Healthy Home feels "solid".  This China-built upright cleans very well.  I was surprised to see that it even picked up debris from the sides of the head.  
 
The two switches for power and brushroll power on/off at the fingertips is a real plus.  The hose and cord are also very long which is another plus.
 
The vacuum is on the heavy side, but that is do to the cyclone dirt chamber and the brushroll motor.
 
Bissell and Samsung have their own patented features on this machine as well as some others.  
 
The vacuum filtered well.  There was a slight dusting of the black premotor filter, but this can be rinsed out occasionally.  I do think that the filter should have been designed differently-larger.  I also would have liked seeing a washable final filter on this vacuum cleaner.
 
For this price, it will be a big seller for those who cannot or will not purchase a $400 vacuum cleaner.  They will still get very good results.  The price will drop after the introductory period and there will be sales, so this will be even more appealing.
 
Now, as for the Bissell Momentum, that is a different story from the Healthy Home.  The Momentum looks and feels "cheap".  The "bagless feature" is not that great.  It uses a flat barrier to try keeping the dirt from rising up.

The bristles are neither hard or soft; they are in between.  They seemed to be somewhat flexible to the touch, due to the fact that the bristles are not as thick, and are not as packed as tightly together as on other brushrolls.

The Samsung looks like a good unit. My guess is that if LG can get the multi-cyclone design to work right, Samsung can, too.  I would be more tempted to try this unit that the Euro-pro.

According to the BISSELL web site, the Healthy Home has a 2 year warranty just as the DC07 Original at Wal*Mart for $379.  With 8 cyclones, just like the DC07, and a host of features that the dyson DC07 model (and even the newer dyson models lack including a brush roll more fitted to USA carpets), and the lower price, the HEALTHY HOME gets the selling edge IMHO.
 
The DC07 models at $399 plus are going to come under fierce competition by all the big box retailers who carry the Healthy Home.  Maybe that's the reason that most retailers recently including SEARS have had the DC07 models advertised for sale.  In anticipation of the BISSELL's Healthy Home launch.
