Cleaning Accessories:

DT640 Utility Vacuum

The vacuum head can be mounted in front of the DT640 on a dual actuating arm. One actuator tilts the head 20 degrees, and the other raises and lowers the head 20 degrees. The vacuum head concentrates the suction at the tank’s floor to focus the pumping on sedimentation. The hose connects to a submersible pump outside of the tank. A camera is located on the main body of the crawler that monitors the vacuum head as it removes debris. The utility vacuum package doesn’t include the hose or pump.

DT640 Pressure Washer Kit

Choose between three different pressure wash kits, 310mm, 500mm, and 1000mm. For optimal cleaning, the integrated arch kit can raise, lower and rotate the spray head 20 degrees. In addition, the head supports up to a 4,000 PSI pressure washer unit. Hoses and pressure washer machines are not included in the DT640 pressure washer kit.
