Normally it would, but sometimes it gets stuck. Mostly our fault for that as we didn’t put the docking station in the best spot. Ideal location for that, per the instructions, is an open spot where there’s about 3 feet on each side.
Hmmm. Not sure why that would be but could be a charge issue. When you first set these up you should put it in it’s charging station to top off the batteries. You’ll know it’s charging as it will light up. If it’s not lighting up you may want to check your plug connections. Hope you’re able to solve the issue.
I’m not actually sure as we live on only one level. It has automatic floor detection but that’s more implied for knowing carpeting from hard wood floors it appears.
