i would like to build a vacuum cleaner using the ESP32 board. I am currently choosing the motor to run with the project using some knowledge i have from fluid mechanics.
(The ESP32 board because it has integrated wifi and bluetooth, therefore saving more space).
I have a choice between two DC Motors air vacuums. Which one do you think would correspond to a home made vacuum cleaner.I am asking this because i do not have any experience dealing with vacuum pumps and the motors will be bought from China. I would like to not make mistakes, as the delivery time is very long. )
Choice 1: (the smallest)
Choice 2: (the biggest)
