A battery powered robotic cleaner is a nice back-up to have. They are around $250, and when your main pool cleaner breaks, which they do often, it's nice having a back-up ready to go.
Do you know of any long lasting robotic pool cleaners? My Polaris P825 robotic cleaner cost me $1000 and it only lasted 4 years. And to replace the motor and cable they want to charge me $800.
Durability is always the problem with these items. You can usually tell by the warranty the expected life. The manual only takes about 20 minutes and is good exercise. I leave the others to the rich.
