Creating Power Wash – A Satisfying 3D Cleaning Simulation Game

Power Wash is a calming yet addictively satisfying 3D simulation game developed by our expert team specializing in mobile game development services. From grimy backyards to grease-stained garages, this game turns everyday cleaning into a therapeutic and rewarding experience. Our client wanted to tap into the growing trend of stress-relieving simulation games, providing users a relaxing escape with stunning visuals, smooth controls, and realistic water mechanics.

Project Type

Full-cycle Game Development (Cleaning Simulation | Cross-Platform).
Game Engine: Unity 3D.
Technologies: C#, Unity Shader Graph, Blender, FMOD Audio.
Platform: Android & iOS.

Challenges

While cleaning simulation seems simple on the surface, the game required smart planning and custom systems to deliver a realistic and engaging experience:

Realistic Water Physics: Needed highly responsive, smooth water spray effects with visual feedback as dirt layers were removed.
Dynamic Dirt System: Each object required layered grime that could be cleaned in stages, not just a single wipe-off texture.
Upgradable Tools System: The game needed an intuitive tool and nozzle upgrade system, with different spray patterns and water pressure effects.
Variety of Environments: Each level had to be unique, ranging from small patios to massive industrial complexes, without overwhelming the user.
Performance Optimization: Required detailed surfaces and fluid animations while maintaining seamless performance on low- to mid-range devices.

Our Solution

We focused on delivering a meditative user experience without sacrificing realism or gameplay depth. Here's how we tackled the core challenges:

Dynamic Dirt & Grime Layers: Built a layered dirt system that responded in real-time to spray angles and distance, showing progress as surfaces got cleaner.
Realistic Water Jet System: Created custom water shaders with splash animations and refraction effects for true-to-life cleaning feedback.
Intuitive Upgrade System: Users could unlock advanced nozzles, cleaning agents, and water pressure levels, each affecting gameplay.
Diverse Cleaning Environments: Developed over 20+ locations, including muddy playgrounds, greasy workshops, car washes, and rooftops, each with unique textures and sound design.
Relaxing Audio Design: Integrated FMOD-powered ambient sounds and cleaning spray SFX, accompanied by calm background music to enhance the stress-relieving vibe.
Smooth Mobile Performance: Used LOD (Level of Detail) modeling and optimized mesh colliders to ensure 60+ FPS gameplay even on entry-level smartphones.
