Lost Water From Pool When Using Polaris 280

First time pool owner here and here is my problem:

This Monday was the first time I used a Polaris 280 to clean my pool. When I turned on the Polaris booster pump, the water was above skimmer line. After running the Polaris for a while(not sure how long), water went down below skimmer and the booster pump was automatically turned off.

I put water back to the pool and turned on the Polaris. It happened again and water was below skimmer! I have a big pool and it takes me about an hour to drain 1 inch of water from the pool so I don't think it's evaporation. I looked the area around the booster pump and the main pump and couldn't find any trace of water. And I didn't have the same problem running the filtration with main pump on and the booster pump off.

Does anyone have an idea about what is wrong and how to fix it?

Thanks a lot!

Any chance it's the tail spraying water into your yard? They are known for that when misadjusted.
Thanks for the reply. But that is not possible since we are talking about an enormous amount of water here. If water was sprayed into back yard, I would sure notice.

Maybe a cracked pipe on the pressure line to the cleaner? Would have to not leak much when not under pressure.

The pool is pretty old, not sure exactly how many years. Is the pressure line underground? I don't see any water around the booster pump.

Pressure side pool cleaner leaks are pretty common. And yes the line is underground. A pressure test will usually confirm the leak, however locating it and fixing it can be difficult. Unless you're pretty sure what to do, it's probably time to call in a pro :cry:
