I looked up two entry level machines on a Canadian website:
* Top loader - 4.4 cubic feet, IWF 6-1/100
* Front loader - 5.0 cubic feet, IWF 3-1/5
Not knowing what those meant, I looked it up. The "water factor" represents how much water a machine uses, in gallons per cubic foot of capacity. In other words, the front loader uses about half the water that the top loader uses.
As another commenter said, top loaders are different in the EU - in North America, the whole drum is turned on its side and water must fill as far up as the clothes go - there's no tumbling action to shift clothes in and out of the water at the bottom of the sideways drum in a front loader (and a European style top loader)
