This is an automatic system and the pool sweep can start at any time.  You should turn off the pool sweep if you are removing leaves from it or removing it from the pool.  You can so this via the Pool App or lighted push-buttons on the Intelligent Pool Controller if you have these.

If you do take a pool sweep out of the water, we suggest you aim it so that if it starts inadvertently, it ‘walks’ into the water.
