After several successful uses in both auto and manual mode, my Bissell spot shot (pet) will only work in manual. The "hose" button is the only button that works and it works fine, but what happened to "hands free"?? This question has been asked by others here before, and the solution is to read the manual--- there is NOTHING in the manual that addresses this problem... My machine is only a couple of months old and was purchased on-line so returning it to dealer is not possible. Manual says to return it to Bissell.... anything I could try before I have to hassle with shipping it back? thanks
