Mini Vacuum Cleaner_2021

I designed new vacuum cleaner 2021 version.
I wanted to improve design and performance and adopted new parts to try it.

Materials are 18650 battery, 24V Motors, DC DC Converter.
Motor supplier indicated that this motor can run 20,000 rpm at 24V.
But there is no information of current and I'm not sure how many hours I can use.

Though, I'll use this on desk to clean up small particles in short time, therefore it wouldn't be big problem

The good thing is that 18650 battery is rechargeable, max 1K times.

I hope to get any comment to make this better as my study will be contiuned...

I learned about impeller recently.
And I designed impeller to replace the propeller.

Suction power improved a lot.
