Description
MD Silent Master S900r has the power for up to a 20,000 sq ft area. Notice that the inside bag system is tapered and does not allow for the bag to seal to the inside diameter of the canister. Meaning that airflow can breathe through the entire surface area of the bag system. I have seen as much as 25lbs of dirt and debris inside this unit and it still had great suction. Also notice with this cut away of the S900r, two motors inside the canister. Each motor has three fans meaning that you have six moving fans creating the amazing amount of power. Industry ratings have this meeting the least amount of power for up to 20,000 sqft. Now you can never have too much power so if you want the maximum and have a large home with more than 9 inlets or the motor unit may be over 100 feet away from its furthest inlet then you should consider this model. The Silent Master design is also incredible since with all this power, you may believe that this model would be noisey. Yet it has 50% less noise than units with half the power.
