I love you Guys Some great advice here already Tim.
It sounds like 2 issues
1) Your Battery needs recharging
2) You need to recalibrate the controller
Im preety sure there is no problem with the Pump, It is also worth checking for any blockage in the brush or hose. Are you using an angle adapter or Aqua - Dapter as the control will need to be calibrated with any add on to the pole.
As soon as I can get the scanner sorted I will email you a guide to recalibrate the control.
