What are the utilities and benefits of Two Motor Upright Vacuums?

An upright type of vacuum cleaner is a self-contained unit which has the motor, main cleaning nozzle, filtering system, etc. all built together in an overall vertical shape. All upright types today have motor driven revolving brush rolls and are used primarily for cleaning carpeted floors. They are pushed forward and pulled backward in front of the user by gripping the narrow handle extending upward from the main case.

"Two-motor" as well as other "clean-air" uprights typically produce better performance when using on-board attachments. They also have significantly longer fan and motor lives compared to most "dirty-air" uprights with on-board attachments. Operating noise levels are typically much lower than from their "dirty-air" counterparts. Having a separate motor drive the brush roll, some using a cogged or geared type of belt, can enhance the carpet cleaning ability of "clean-air" uprights. The two-motor design is hard to identify on some models since they look so similar to the one-motor "clean-air" uprights. Other models have a more narrow connector between the main body and carpet cleaning nozzle, making them easier to identify. Most will be identified as having two motors somewhere on the cleaner or its literature.
