  1. High-Rise Window Cleaning System Kelvin Mok CEOLi Ng CFOTommy Chiu COOHoward Lee CTOHubert Pan CTO April 25, 2006

  2. Overview • The Problem • Our Goal • Our Solution • System Features • Future Developments • Commercialization • Conclusion • Questions? • Demo

  3. The Problem • Current methods for high-rise window cleaning:

  4. The Problem • Injuries and fatalities • High costs • Vulnerability to weather • Limited work hours • Fatigue

  5. When accidents occur…

  6. Our Goal • Eliminate need for human cleaners • Minimize weather susceptibility • Maximize time flexibility • Increase effectiveness • Adapt to different high-rises

  7. Our Solution • Automated window cleaning • Personnel moved away from cleaning site • Window surface anchoring • Simple technology • Modular and transportable • Adaptable

  8. Our Solution • <Drawing of device>

  9. Our Solution • <Photo of prototype>
