Tethered or Onboard Water Tank? Choosing a cleaning drone is not only about payload and flight time. The water supply system can directly affect cleaning productivity, flight performance, deployment, and operating costs. A tethered water supply enables continuous cleaning and is well suited to high-rise buildings and large glass façades. An onboard water tank offers faster deployment and greater mobility for smaller or low-rise projects.
