Vacuum cleaners datas are attached , pls consider the motor's power (W) is nominal and not max power which as you know is 2400W for the THOR280 and 3600W for the THOR380.
Answering the question you made me by whatsapp, the airflow's value in the file (l/s) is the total of the vacuum cleaner considering the 2 motors or 3 motors together.
