Not that I have any real stats but I would wager the fact that the use of canister vacuum cleaners far exceed the upright vacuum. Then again, it may be just my personal choice.

Canisters are almost always much lighter which is great for going up and down the stairs. Hauling an upright vacuum around can be very cumbersome especially if you are a little on the week side. Back in the 1900's vacuums weighed as much as 100 pounds.

Getting under tables, beds and couches is a much easier job with a canister mostly due to the power head being separate from the motor housing. For this reason the power head is much slimmer and light weight. This makes your job easier and faster.

There are some locations an upright vacuum just can't get into because the unit is all one piece. With the canister you just have the hose and power head. Even storage of the canister is better as most can be stood on end and tucked away into a corner.

If you want light weight and maneuverability then a canister vacuum is definitely the way to go. There are so many more choices, everything from hand held to truck mounted units for heavy industrial cleaning.

Even the pricing range is better as there is a size built for just about any kind of job. No sense purchasing a bigger unit than you need when there are so many choices available. This is somehthing you won't find in an upright vacuum cleaner.

As stated above these are just some of the reasons for purchasing a canister over an upright. If your house or building is wide open, one floor and has lots of space under beds, tables and couches then an upright would be just fine.

Whatever you choose, make sure it's right for you.
