We have an inground pool with a spa combo. We opened it ourselves today with the help of a neighbor who also has an inground pool. We’ve gotten it running great and we ran the pool pump for several hours while the robot cleaned it. We switched the pump over to the spa and 2 jets are blowing and 2 are sucking. They are all at back level when you sit in the spa and should all blow. I’m not sure what’s going on or how to fix it, thank you!
