Full Text	This invention relates to a multipurpose wiper for use in vehicles. The use of wipers is as such known in the art for the removal of the water or dust from the front wind shield glass of the motor vehicle. The conventional wipers comprises mechanical wipers. There are several disadvantages associated with conventional mechanical wipers. One of the main disadvantage is that the conventional wipers cause hindrance in the vision during its operation. Another disadvantage is that substantial amount of condensed moisture sticks on the front wind shield resulting into poor visibility.
