Mess About: Robot Vacuum Game

Drag anywhere below the bar at the top of the screen to steer, and release to stop. That is the whole control scheme: there are no buttons to learn.

Cleaning 70% of the floor earns the first star and lets you move on. 85% earns the second and a spotless 100% earns the third. The first star is banked as soon as you reach 70%, so running out of battery later cannot take it away.

Two things. They rate how well you cleaned a room, and they are the currency of the house screen: you spend them on furniture for the rooms you have cleaned and on moving into the next house. Each level also carries two side challenges worth extra stars.

The battery only drains while you are moving, so it is free to stop and plan your route. Debris piles drain it faster while you clear them, and doubling back over floor you already cleaned is the most common way to run short. You can also watch an optional ad once per level to recharge, and the UV Light power-up puts charge back too.

A single room that everyone plays on the same day, with a countdown timer instead of a battery. Clean it to 100% before time runs out to keep your streak going. Missing two days in a row resets the streak, and bonus stars land at 3, 7, 14, and 30 days and beyond. A new room arrives at midnight, your local time.

You have reached the end of the rooms we have built so far. More houses arrive in updates, and in the meantime there is a new Daily Challenge every day, plus any rooms you have not yet cleaned to three stars or fully furnished.

Yes. Settings has a Language picker with eleven languages: English, Spanish, French, German, Italian, Brazilian Portuguese, Dutch, Polish, Japanese, Korean, and Traditional Chinese. The game starts in your phone's language if it is one of them.
