Play Operation Cleaner Online

Operation Cleaner is a lesser known MS-DOS title from the early 1990s, released as part of a budget compilation of zero-cost games. It was developed by a small team whose name doesn't often come up in conversations about the platform, but it fits right in with the era's experimental, often quirky shareware scene. You won't find elaborate backstories or cinematic cutscenes here; it's a game built around a single, clear premise.

You control a janitor armed with a mop, tasked with cleaning up every tile of a room before a timer runs out or a spreading mess overwhelms the level. The core loop involves moving from screen to screen, scrubbing away grime while avoiding obstacles like slippery spots and patrolling enemies. The challenge comes from managing the constantly encroaching filth, which forces you to work quickly and plan your route. It's a simple, frantic puzzle that makes a surprisingly tense experience out of a mundane chore.

Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
