Manual searching was banned 25 years back with the passing of the Employment of Manual Scavengers and Construction of Dry Latrines (Prohibition) Act, 1993, however it keeps on discovering specialists. The occupation endures basically due to the continued presence of insanitary restrooms. There are about 2.6 million insanitary restrooms (dry toilets) that require cleaning by hand, as per Safai Karmachari Andolan—a NGO that moves in the direction of nullifying manual scavenging, and maybe, solitary one in the nation.
There are basic issues also, which power individuals to enter septic tanks. “Septic tanks are structured seriously. They have designing deformities which implies that after a point, a machine can’t clean it,” said A Narayanan, executive of Chennai-based Change India.
The circumstance could go from terrible to more regrettable. Under the Swacch Bharat Mission, a large number of septic tanks are being worked in country India. By 2019, about 30 million septic tanks and pits would have been burrowed along the Ganga.  On the off chance that the Central, state and nearby sanitation programs don’t take up fecal muck the board as a need, the onus will move to the most minimal rung of the general public to clean a large number of dry toilets worked with tearing rush.
Adding to the issue is the way that numerous urban communities don’t have sewerage that covers the entire city. Now and then, sewage lines are associated with storm water channels which get stopped up and request human mediation.
Open channels, as indicated by Narayanan, are additionally seriously structured, enabling individuals to dump strong waste into them, which emphasizes the issue. Ill-advised transfer of condoms, sterile napkins and diapers stop up the channels, which machines can’t clear.

- Asphyxia occurs when the foreman does not get enough oxygen to sustain life. It may be due to low oxygen level in the atmosphere or high hazardous gas concentration.
- Difficult to work in any climate.
- More than 3 workers for one manhole
Bandicoot, developed by Genrobotics, is the immense combination of mechatronics and robotics to solve a problem that has been considered a menial job by the society. It is a semi-automatic robot that is aimed at cleaning of sewers with the help of positioning of pressurized jets in an accurate manner and to completely eradicate manual scavenging from the country. Bandicoot is designed such that it can do the work equivalent to five human beings within minutes and is designed for both automatic and semi-automatic modes .
The robot has a capacity of cleaning small sewers in 15 minutes and takes about 45 minutes to unclog bigger ones. It requires only one person for operation and weighs around 80 kg. It can lift heavy metal covers on its own, drops its arm into the manhole, scoops out the solid waste and dumps it in a bucket. The operation of Bandicoot can be seen on a monitor and can also be used to check the sewage apart from jetting the sewer lines.
The robot has one sole purpose of its existence which is to eliminate the manual scavenging in India and give them a decent life without the fear of losing their jobs and lives. Somehow, the developers think that it will also break the caste system which has prevailed from ancient times in India.
The innovation aims at social welfare perspective and the development team will have a better future as it will further finance their next innovations.
