The Orbit AU400 Guardian is definitely to be considered as one of the best central vacuums on the market today. The AU400 uses one of the most solid vacuum motors in the world and a simple circuit board that is reliable and proven to last decades.

You may be looking at central vacuums because your old power unit burnt out or perhaps your moving into a new home. One thing is for sure; if you are looking for the best central vacuum the Orbit AU400 is to be considered.

The Orbit AU400 uses a Lamb-Ametek  2-stage (two fans creating vacuum power) 6.6″ bypass-motor this is what creates all that power. Bypass motors are to be considered “Premium” motors with a long life-span, maximum efficiency and raw power with no performance drops. Premium motors are much more intelligently designed compared to flow-through motors which are typically are sold at big box stores.
