Pull out the basket

You reach in and pull out the basket.  It's filled with debris and nastiness, which you quickly haul over and dump into a garbage collector.  Ignoring the smell, you put the basket back into the filter and click it into place.

Glad that the task is done, you close it up and see Poolcheck nodding at you.

"Good job, rookie!" he says.  "Now get some sunscreen on - the sun can be BRUTAL!"

You head over to the snack bar.
