Mark, I Can See You Aren't Familiar With Ohm's Law

In a vacuum cleaner the voltage can be seen as the suction, the current as the airflow and the carpet is the resistance.So low suction (voltage) will mean a low airflow (current) through a given resistance ie the carpet. Proven by science.
==========================
E=IR and P=IE
Airflow would be liked to voltage and suction (water lift) would be likened to current. So many people get this one backwards.
As resistance increases (carpet), current increases or more accurately ATTEMPTS to increase. If the current (suction) cannot maintain the voltage, the voltage (CFM) begins to drop under an increasing load (resistance).
Voltage is a potential difference between two points, say earth ground and something else. The strength of the voltage (ability to resist a load) is current. The strength of the airflow is suction, which is the ability to maintain CFM under a resistance (carpet).
Don't confuse the above with what the electrical motor is experiencing as that is a different ball of wax.
Look behind the Kirby Avalir and Diamond Edition in my videos. See that giant blob of electrical testing gear? Do you know how long I've been designing/building electrical circuits and power supplies to feed those circuits? Try over 40 years. I'm also FCC certified so I know how to design/build transmitters and antennas.
