The first two measurements were easy to get, the last one (CFM at the nozzle) required me to build an airflow box. I think this pic should easily illustrate where and by how much CFM is lost in this machine. I think this is typical performance from a cyclonic bag less cleaner.
From the base of the machine through the cyclones, there is a loss of 117-74 = 43 CFM. From the cyclones to the nozzle, there is a loss of 74-59 = 15 CFM. Total airflow losses from the canister base to the power nozzle (held at a 45 degree angle to the floor) is 117-59 = 58 CFM or about 50% of the original airflow. Last note: the rug plate opening is fairly typical (about 28 square inches), but CFM density is well below average, about 2.1 CFM/Sq. In. If you ever wondered if this expensive 12 Amp beast was capable of deep cleaning, I would argue it probably wouldn't be, even with stiff bristles on the brush roll. Bill

So no comments on a previously popular cleaner? | ||
