I've had one for 4 years and I pull the wheel away from the unit and put the pin behind the wheel. It seems to not tangle the cord as much and works well in my 20 x 40 pool. If I am outside, I will switch the pin from one side to the other half way through the cycle.

I also set my timer just long enough for it to run the length of the pool. Once you have it set you don't have to mess with it again.

I also run mine for two cycles and it usually gets the whole pool. Sometimes it will miss the long edges but I can use my leaf pool to get it position to run tight against the 90 deg edge right before I take it out of the pool.

I hope you enjoy yours as much as I have enjoyed mine....it was the best 500.00 I have ever spent!!
