How the math works
Monthly savings × swim-season months gives your yearly savings. We subtract a yearly parts allowance, then compare against the robot's price (the lowest price we've seen on Amazon) to get the payback period and the net result over your chosen years. Electricity is a few dollars a year for robots, so we leave it out. The one cost we can't price for you is replacing a cordless robot's battery or the robot itself at the end of its life: if you plan to own it past 4–5 years, readhow long robotic pool cleaners last.
