Sleeping SimBots emit ones and zeros instead of Z symbols as a reference to binary code. Unlike the Servos of The Sims 2, SimBots possess no ability to shut down to conserve power, or use solar power to recharge, and may sleep in a bed as any other Sim does. However, their needs are named differently and have a gray color. SimBots have most of the same needs as human Sims, except for hygiene.
