Fan Forced vs. Bypass Designs

Fan Forced type vacuums are usually uprights. These designs force the dirt and debris through the fan and motor system. The brush roll (or agitator) sweeps this debris up, sends it to the motor system which in turn uses its fan to force the substance into the dust bag or container. You have to be careful what you pick up because if you get something (nails, screws, coins, plastic pieces, wood pieces, etc.) caught in the motor which jams the fan and keeps it from spinning or break the fan blades you have a problem. Air flow is almost always low.

We carry only a few commercial type fan-forced machines.

Bypass vacuums are based on the standard everyday canister types of the past. With this design the motor system sits behind the bag or container (instead of in front like the Fan Forced systems) and draws the dirt into the dust bag or container directly. This method is the best design thus far. More manufacturers are designing their upright type vacuums like this today because it is a much more efficient method. In most cases this means more suction power and control debris from getting caught in the motor system.
