I’m working on a small handheld prototype that needs to suck up small amounts of water/soapy water through a short tube and move it into a small removable reservoir.

Its not alot of liquid just small surface amounts but Id like to build it to be compact and preferably USB-rechargeable.

I’m confused about which type of (mini, the smaller the better) pump/motor is best for this:

• mini diaphragm vacuum pump
• peristaltic pump
• small wet-vac/blower motor
• self-priming water pump

My priorities are:

1. can pull liquid through tubing without being submerged
2. low clog risk
3. not insanely loud
4. compact enough for a handheld prototype
5. beginner-friendly wiring, ideally 5V USB or USB-C rechargeable

Also, if anyone has advice on how to safely connect this to a small removable tank/reservoir without leaking, I’d appreciate it.

I’m a beginner, so simple part names/search terms would help a lot.
