Researchers at a Czech company, Neovision, have invented a duct-cleaning robot called Jetty.
This machine is joystick controlled and has a 1024×768 pixel camera. It receives power and signal over a Ethernet-over-Cat5 cable, limiting its movement to about 35 meters right now, but it can clean and inspect kitchen, industrial, and office ducts with relative ease.
The robot uses dry ice to clean ductwork and can move up and down using its tread-like feet. The jets are situated on the middle of the robot for maximum pressure and Jetty can move through circular, rectangular, and square ducts and go up curves.
