MD AirMaster XL A900r2Q 240V, my favorite even though I don't have one yet.

I picked this one for my future 19,800 Square Foot mansion I plan on building someday because of how powerful and efficient it is compared to the PurVac Killer Whale 240V. Also 50' Corded Electric Sebo ET-2 power nozzle central vacuum hose sets with Wessel Werk mini handheld power nozzles to go with my future MD AirMaster XL A900r2Q 240V. To go with the MD G23 240V, and the Beam 4500A 240V I'm going to use with disposable synthetic throwaway bags instead of as a bagless system.

Thanks for your desire to obtain one of our AirMaster XL Model A900! It is actually identical to the Silent Master S900 but it is upside down. You do need to always use a disposable bag in it so the real advantage is only emptying from the bottom. Consider the S900 though as it runs cooler with the motors on the bottom and that also puts the noise lower to the ground! Coupling it with a SEBO attachment set will be absolutely killer!

I'd second with going for the S900r2. The top doesn't require any latches to put on and it can be easier to change the bags out with the unit being closer to the ground. As like the other user mentioned (who appears to be an employee from MD Manufacturing), with the motors closer to the ground, the quieter it can be. And price wise between the two, the SilentMaster is cheaper so in my opinion it isn't worth extra going for the AirMaster when mechanically they're the same thing. Also, I'd recommend the Stealth (Lindhaus) powerhead over the SEBO. The Stealth has twelve height adjuster settings compare to SEBO which has four, the brushroll on the Stealth is designed to have less hair tangled up or lint caught in the bristles whereas I always see SEBO brushes get so dirty, and SEBO has a five year warranty on the belt whereas the Stealth offers a lifetime warranty. These are the reasons why MD is still sticking with Lindhaus as the best power nozzle on the market, I even had one before for my SilentMaster from the last cabin that I used to own. But if for whatever reason MD didn't carried Lindhaus anymore, I would've went with SEBO as my next choice because they are overall excellent power nozzles.
