Single stage are cheaper to produce. |

I also noticed this and I felt weight has something to do with it. Everone seems to be looking for a lightweight vacuums. |

The motors in the Tacony tandem air machines are like 6A each.-12A(1200W) total with BOTH motors going as in the carpet clean mode.For bare floors and hose mode only one motor runs-the clean air motor.I am quite pleased with my tandem air machines.up there with my Kirbys. |

The difference between a singe fan and a dual or triple fan motor from an engineering point of view is what design will give the best performance for the cost, weight, size requirements that they are given. As Hans said, a single fan motor can move more air while adding more fans will cause a loss in ai flow, but an increase in sealed suction. Personally I don't feel there is a connection between how many fans a vacuum motor uses and how long it will last, its mostly coincidence that most modern, low quality motors are single fan. Many high quality machines like Miele and Sebo use single fan motors that will run for years. The reason that more and more motors are going to a single fan design is that modern technology and design has given us the ability to make fans that are more effective, think the fans you've seen that taper to a taller fin in the middle. These new fans give the advantage of being able to get the better airflow of a single fan motor, but also create as much suction as a twin fan design. And to go even further, both Domel and Ametek now make motors that have 2 of these 'vortex' fans, my central vac has 2 5in Domel motors with dual vortex fans, and its a real beast.
