It had not been running all season.

I have been cleaning the pool myself. The tip of the tale had worn off last fall and I was finally able to stop and buy a new tail for the cleaner. After I connected the tail and turned on the cleaner pump I could tell the cleaner was not working properly. The water flows from the tail and from nowhere else. The jets that propel the suction into the Polaris cleaner are not working. No water flow from those jets. What does that mean? Thank you.
