My personal opinion is to remove it each day and rinse out filters every 2 to 3 uses minimum (i do mine every other day). I did extensive research before investing in the Oasis z5. Most of the pool shops (other than Leslie's) and pool cleaning companies by me advise against them because they are expensive to fix, so I wanted to do my own research. After all, a good cleaner makes pool cleaning companies unnecessary so I didn't value their opinion too much. I spoke with a lot of long time owners and repair shops. The people who had issues with their units after 2 or 3 years left their units in all the time. The people who had units for 4, 5 or 6 years took them out regularly. Yes, a lot of the units have scheduling programs so that you can leave them in, but lets think about this for a minute. This is a piece of electronic equipment made of plastic sitting in water that is treated with chlorine, which is corosive. The only thing that keeps the water out of the electronics is some gaskets. If they are constantly sitting in the water, the gaskets will fail and the water will get into the electronics, probably right around the end of the warranty. Why wouldn't the repair shops and manufacturers tell you its ok to leave it in. When the gaskets fail, you have to spend $400-$600 for a new motor or just buy a new robot. Either way, they win. Thats why I always encourage people to get a unit with a good warranty and make that more important than the "gimick features."
Im not saying there isn't a place for the scheduling programs because there is. I think they are good if your are going away for a few days or a week or something like that. In that case, yes, put the robot in and set a schedule so you don't come home to a dirty pool. But if you are around, IMHO you're asking for trouble down the road by leaving it in all the time. Robotic cleaners are a big investment and we want them to last as long as possible.
