At launch, PowerWash Simulator is available on Xbox One, Xbox Series X/S, and PC. It’s currently unclear if the developers have any plans to release the title for PlayStation consoles or the Nintendo Switch, though it’s possible it may come to those platforms in the future.
If you have a subscription to Xbox Game Pass, you also don’t have to purchase this game for a chance to play it, as it’s currently available to those with a subscription for both Xbox consoles and PC players.
