I got a visit from a salesman with a linecard for Knowles microphones. He gave me some samples I will try out. The Skoobot buzzer is weak because it is only 10mm in diameter, not much I can do there. The microphone I use is directional somewhat and has 23dB gain. The new microphone he showed me has 36dB gain, much higher. This may actually work and hear the buzzer of another robot, or make normal conversational volume actually work well. I can try the microphones on my test rig. The sample microphones are soldered to flex, which is a good idea for me to, for example, extend a flex to put the microphone where I want it, like right on top facing up. But this would add a lot of cost though.
