Starting with the assumption that one knows what a pool vacuum is. (1) Connect a pool hose to it. (2) Connect the pool hose to the vacuum plate over the leaf basket. (3) Connect the vacuum head to a pole long enough to get the reach you need. (4) place the pool head (hole down ) on the pool floor. (5) start the pump, (making sure it is set to filter). (6) Systematically rub the pool vacuum head along the pool floor and walls where possible until you have covered all submerged surfaces. (7) Stop the pump. (8) Unplug pool vacuum hose. (10) Remove vacuum plate and clean rubbish out of basket. (11) Replace basket. (12) check that Hair/Lint basket against pump is clear and clean out if necessary. The pool should now be ready for use if the filter is also clean enough for use.
