Racer gets stuck on curved step. The plastic nose protrusion contacts the vertical surface of the step keeping both tires just a fraction of an inch away from contacting the vertical step edge to drive the cleaner up and away. In reverse the back wheels slip off the horizontal step and the plastic bottom of the cleaner hits the step corner, lifting the front drive wheels slightly into the air and defeating its ability to get the cleaner off of the step. I have a short video clip but it looks like i can’t post that here. If this made sense I’d love to hear of any creative ideas to solve this problem. Thank you!!
