Hamster Help

Hi so i have a robo who is turning two in a couple of weeks, and he really isnt very steady on his feet he is a little wobbly and yeah, would anyone recommend/not recommend setting up a 'retirement' cage, where everything is closer together so its not as far for him to walk, everything is on the same level like food and water etc. Just wondering if this 'retirement' cage would benefit him or has anyone does this before with older hammies? If anyone had any advice please let me know!
