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 good performance from a 2000's bagged cleaner.
From the base of the machine through the hose to the head assembly, there is a loss of 127-103 = 24 CFM. From the hose connection to the nozzle, there is a loss of 103-65 = 38 CFM. Total airflow losses from the canister base to the power nozzle (held at a 45 degree angle to the floor) is 127-65 = 62 CFM or about 49% of the original airflow. Last note: the rug plate opening is slightly larger than average (about 27 square inches), but CFM density is slightly below average, about 2.4 CFM/Sq. In. If you ever wondered if this expensive 12 Amp beast was capable of deep cleaning, I would argue it probably would be, but you might have to go over the same spot more than once. Bill |
