Sediment deposition or settling in water tank is common problems for all the water storages. Empty out the tank and clean sediment is a specialized job. This machine avoids tank empty out, inside entry, water wastage and with less power consumption and within few minutes removes sediment from water tank. This works on local water circulation and filtration. A brush at its bottom creates dusty localized cloud which will be absorbed by machine and through filter clean water will be returned to tank. This machine is suitable for cleaning settled or deposited sediments in house hold water storage tanks for capacity from 500 liters to 2000 liters. Alternatively from 600 mm depth to 1800 mm total depth of RCC or plastic water storage tanks.
