I've had my m500 for about 5 years now, and it's been a reliable lifesaver keeping the pool clean. One of my only complaints about this guy has been lack of a remote control, or having to stand right on top of the unit...just to use the app via bluetooth. I noticed that the m600 has wifi, and that the main supply looks fairly close in relation to the m500. Before I get too into the weeds, has anyone ever looked into whether swapping in a unit like that might give that kind of functionality to the older unit?
