Canister Vacuum Deals
Many manufacturers make both upright and canister models (not to mention a host of other specialized vacuums). Historically canister vacuums have been better for hard surfaces than their counterparts. They also tend to be quieter and, unfortunately, slightly more expensive (although this is not always the case).
It is also easier to clean stairs with the canister vacuum, and due to their lower profile cleaning around furniture is usually more manageable. Upright models have tended to be better at cleaning carpets, however. Recently the distinction between the two types of cleaners has become more blurred as manufacturers attempt to bridge the gap between each type's strengths and weaknesses with the addition of specialized features and tools.
If you have a lot of carpet to clean you may want to consider a canister that has a powered brushbar in the nozzle. The brushbar digs into the carpet and is able to pull up more dust and debris than simple suction alone. The brushbar is especially important if you have medium to high pile carpet. There are also differences in the way brushbars may be powered. The best approach is a motorized brushbar but some are powered by vacuum suction alone. Those powered by suction are often called turbo powered or turbo brushes or something along those lines. While the turbo approach does work it is generally not as good on deeper pile carpet. If you have mostly hard floors to clean the brushbar is not as important.
