2. INTRODUCTION The manual, chemical and mechanical cleaning methods cannot meet the needs of cleaning. Manual cleaning is the most widely practiced method nowadays. The roofs are Manually cleaned using scrub with the wire brush. This method is time consuming and tiring. However a number of attempts have been made for cleaning the various roof surfaces at present , only few are dedicated towards automated roof cleaning.

3. ABSTRACT To design and fabricate a “Hydro jet”(semi-automatic roof cleaning machine) which is capable of cleaning dirt, grime, algae etc. on roof having reliable slope. To make the controlling of the machine user friendly such that person with less technical knowledge is able to use it. To make a machine which will take care of safety of persons, save time and also shouldn’t damage roof structure. This method is suitable for small, medium as well as for large roof cleaning.

4. Problem statement Traditional cleaning methods often consume excessive water and use harsh chemicals, causing environmental harm. Ensuring the safety of workers and the structural integrity of rooftops during the cleaning process is crucial. The project seeks to develop an hydro jet-based solution that efficiently and environmentally cleans rooftops .

5. objectiveS To design and develop a device which cleans the rooftop to maintain the integrity and functionality of the roof structure. To design a device which will reduce the manual work and make the system automated.

7. CONCLUSION In the present day scenario the roof cleaning is not a common practice that is carried out in a country like India, and even if it is being carried out somewhere it is done with the help of labors. This labors are forced to climb on the roofs sometimes located at much higher heights without taking any safety measure. The ideology of bringing ahead the idea of “Hydro jet” a Semi-Automatic roof cleaning machine, is with due respect to the concern of safety of these workers. This machine will enable a person to carryout roof cleaning operation with minimum physical efforts and mainly without any labor dependency
