For cleaning water
reservoirs and water towers
Traditional cleaning processes meant that water towers and
drinking-water reservoirs had to be emptied and manually cleaned or
divers sent down. In both options, the reservoir has to be taken
offline, which can lead to major disruptions in the main supply system.
Emptying a reservoir is time consuming and cleaning is labor intensive.
Sending divers down in drinking water also entails a risk for
contaminating the water. When the robot was developed the ambition was
to design a vehicle that could clean effectively without having to shut
down the reservoir and without sending personnel down into the
The robot is remote controlled and equipped with rotating brushes and
a powerful pump that directly pumps out all loosened sediment – without
raising turbidity in the reservoir. It is equipped with a video camera
that facilitates inspection of the inside of the reservoir. The entire
cleaning process is documented and the customer receives both a
videotape and a written report.

|Wall cleaning under water
The Robot has in this special application been specifically designed
so that it floats when dropped into the tank. When the pump is started
the cleaner moves automatically to one of the walls in the tank and
sucks itself onto the wall. It may then be remotely driven along the
entire wall. In this application down to 5- 6 meters depth. When the
first wall is cleaned the pump is stopped which makes the cleaner float
to the surface and is now ready to be steered onto the next wall.
