You don't 'need' chlorine by way of SWG, but you consider that disposable sooner based on the extended length of your season. The same as you should with the life of the robot.You actually don’t NEED a robot but you ABSOLUTELY NEED chlorine
Like new plates not being available for the SWG ? Or the electronics on the cell which are unreplacable ? Either way the cell fails when the time comes, you are replacing it.Fair use” is debatable. I personally see nothing fair about a company actively keeping critical spare parts off the market.
Not to you but many others do have a cost to run the main pump higher, and/or the booster pump, or the SS pump, so for them there is a cost to operate the cheaper cleaner, which also has a maintenance cost on top of buying it in the first place.Variable speed pumps and valve automation renders the “cleaners use a lot of energy” argument moot. My suction cleaner runs fine at the same speed I use to generate chlorine and skim. So if it runs at the same time as the POOL mode then there’s no cost penalty.
Just more food for thought because you liked me asking which overpriced cellphone that gets replaced every couple of years due to planned obsolescence you were responding with. (To the folks who weren't there, it was a trick question with no correct answer
