How to read the comparison
Air watts combine suction and airflow into one figure and are the fairest single number for whole-house units. Water lift matters most on long pipe runs and upstairs inlets; CFM matters most for carpet with an air-driven turbine head. The sq ft rating is the maker's own and is not standardized between brands. Noise ratings are measured by each maker under its own conditions, so treat a 2 dB gap as a tie. Garage and RV units are not whole-house systems; compare them with each other.
