This thesis, titled “Development of Beach Cleaner with Motorized Rotary Sweeper,”
sought to develop a cleaning machine to help beach maintenance of trash or debris washed
ashore by the sea during tides and human littering. The prototype incorporates a rotary
sweeper using an AC induction motor, which is placed into a sifting container to separate
sand from the collected waste or debris during collection. The design used pneumatic
wheels to maneuver across the sand, imitating a wheelbarrow. The frame of the prototype
was made from 304 grade stainless steel, galvanized iron, and acrylic panels. The acrylic
panels served as the casing, and enclosed with acrylic sealant to prevent water or other
materials to entering the electrical components of the beach cleaner prototype. In 15
minutes, the prototype was able to collect 1.74 kg of waste and debris and in the
uncontrolled tests, its overall effectiveness in collecting was 69.96% with the weight
collected is 1.74 kg. In a controlled environment, the data shows its efficiency rate is
63.83%, with the weight of trash being 1.11 kg from the 1.74 kg, collecting up to 0.206
kg/min in 5 minutes while manual collection was 0.114 kg/min. The prototype is capable
of covering 200 meters of land. The prototype was evaluated and obtained a very good
rating in terms of functionality, workability, durability, safety, aesthetics, and economy.
Overall, the beach cleaner with a motorized rotary sweeper was successfully designed to
collect small to medium waste or debris by sweeping and sifting.
