I've searched and found posts saying many of you leave cleaners in the pool 24/7, mostly NOT robots. I left my Platinum Legend in 24/7, but now have an Aquabot 4WD. An Aquabot FAQ:
12. Should I take my robotic pool cleaner out of the pool once it is finished with the cleaning cycle?
The robotic pool cleaner should stay in the water at least 20 minutes after running to allow it to cool down before it is removed from the water.
Not really answering the question. It's easy to pull it out, but my 2 concerns:
1. Pull it out and have it exposed to 90-100 degree heat daily (drying out gaskets, degrading plastics, exposing motors to heat)
2. Leave it in 24/7 (keeping it cool, but bleach attacking gaskets?)
I tend to think in the pool is better for the unit (unless you are shocking). Less strain on the cord, less strain on the back, keeps rubber roller and wheels wet (better than dried out). The baskets are so big, and unless you have a lot of silt or big leaves, I can't see needing to clean them but every 3 or 4 cycles. The clear plastic on top makes it easy to see what's in the baskets at the bottom of the pool (very cool). It will be interesting to see what others with robots are doing ("robots" being something with an electrical motor in it).
