Mine also came with the tank flusher fitted on the other side of the black tank. It does a good job of rinsing the tank clean however its too far and not concentrated enough to keep the probes clean. Traveling with TP on the probes should knock it off but doesn't. The problem is more like debris film coating between the probes which is just conductive enough to make circuits to the return side of the probes. I use a high velocity probe nozzle I fabricated from plastic pipe. You can also buy them commercially. Its a pain to bring a clean dry hose through a window but you'll have clean tank and probes
using both methods.Once a month is plenty. I'd be cautious about removing those probes too often. You'll soon have enlarged holes and you'll be SOL.
