2. Design Brief “Ever find cleaning windows a hassle? Wiping dusty furniture an irritation? The Modular Multi-Surface Cleaner is a One- Stop Solution to all of your surface-cleaning problems! Practical, simplistic and innovative, it will make daily chores like cleaning windows and furniture an easy and pleasurable task. Less hassle, less energy and less time. The Modular Multi-Surface Cleaner.” ZM

3. Introduction YI

4. Problem Having to change between different cleaning materials while cleaning windows, dusty furniture and other surfaces For example: wetting and then drying the window- will require a wet cloth then a dry cloth YI

5. Solving the Problem 2 cleaning materials can be used simultaneously, one after another- no need to manually switch cleaning materials Easily customizable modular system for all kinds of combinations YI

6. How It Works (3D-Printed Prototype) YI

7. General Concept: 2 cleaning materials wipes the surface one immediately after another Thus eliminates the need to switch between different cleaning materials YI

8. In this example of a combination used to clean ceramic walls, a dry Magiclean sheet will wipe off the dust before the wet sponge immediately cleans it with water. YI

9. Cleaning Materials Absorbent PVA Sponge (for wetting) Cotton Microfiber (for drying) Dry Magiclean sheets (picking up dust) Wet Magiclean sheets (sanitizing) YI

10. Modular System An easy-to-use function allowing the user to CUSTOMIZE the combination of cleaning materials they would like to use Hence suit many purposes (windows, floor, furniture…) MK

11. 1: -Microfiber, and dry and wet Magiclean, can be attached to any of the 2 T-pieces. MK

12. Example: MK

13. 2: The T-pieces are then clamped onto the device’s each side via an easy-to-use Velcro system MK

15. Extended clamp is used to clamp PVA sponge (no T-piece required) MK

16. Possible Modular Combinations MK

17. Combinations Wet PVA Sponge and dry microfiber (for cleaning windows and cars) MK

18. Combinations Dry MagiClean and Wet MagiClean (for picking up dust and sanitizing on furniture) MK

19. Combinations Dry MagiClean and Wet Sponge (for wiping ceramic walls in toilets/ kitchens) And many more! Customizable to your uses. MK

28. Comparison With Existing Products ZM

29. Magnetic Double-sided Window Cleaner Safety string prevents device from falling Simultaneous drying/ wetting Risk of outer side dropping off Only one mode: dry/ wet ZM

30. Magiclean Wiper Easier to clean furniture with short handle CAN be combined with sponge/ microfiber etc. Long handle impractical for cleaning furniture Can NOT be combined with other cleaning materials ZM
