The wheel configuration made more corrections to the robot body stability during arm work while cleaning, so it happened that the robot moved a few centimeters during cleaning and the arm cleaning did not occur on the cleaning object but a few centimeters off. The advantage of the wheel configuration was that the robot could rotate around its own axis in place.
On the other hand, the leg configuration also has its disadvantages. We had to create new reinforcement learning for walking even with the arm configuration. And even so, in some cases the robot went into instability and lightly bumped into the sanitary fixture. Longer legs would probably help :)
