I actually recall looking at this vacuum quite a bit on Electrolux's website, circa 2008. I thought that the design and concept were really cool, but now I can see why this vacuum was short-lived.
Blackheart, the brushroll design looks very similar to the one used on a clutched Dyson, which means it'll get tangled with long hair VERY quickly.
huskyvacs, in addition to the complaints you listed, one reviewer stated that the bag came off in the middle of use, thereby allowing dirt and hair to get into the motor and burn it out.
In late 2008, former UK member vintagehoover (now known as ElectricUtopia on YouTube) purchased a brand new Intensity, and his unit came with LOTS of additional bags in the box, presumably because Electrolux wanted to compensate for the tiny bag capacity.
One interesting video shows the Intensity lifting up 5 bowling balls at once as a demonstration of its suction power.
