A:
The refrigerator is on wheels and it rolls pretty easily once it's supported only by the wheels. The issue is that there are also some supports that can either fully support the refrigerator (lifting it off the wheels) or at minimum, they create friction so the refrigerator can't roll out of place. All you have to do is turn these black octagonal supports in a counter-clockwise until the front wheels are touching the floor. After you are done cleaning, roll the refrigerator back in place, and turn the supports clockwise until they are touching the floor. Setting these is optional, of course, but I would recommend using them to prevent any rolling.
