Every now and then my hot tub gets lots of foreign matter in it.
I combined a drill powered pump with two small funnels and a bit of open cell foam.
This allowed me to suck up all the foreign matter and capture it in the foam.
Future enhancements might be a 3d printed box for the foam that makes it a bit more efficient.
