You're right. I've assumed that it drives horizontally along the wall. As it climbs up the wall, you're absolutely right - the thrust has to overcome the weight AND provide at least a bit of a normal force to keep it pressed to the wall.
Given that the video clearly shows it driving up the wall, this particular vehicle must indeed be able to develop enough thrust to overcome its own weight.
