I'm in the market for a drone that can effectively power wash hard-to-reach areas on various buildings. I'm particularly interested in understanding the different models you offer that would be suitable for this specific application. Could you send me details on the available options, along with their pricing? Additionally, if you have any recommendations for accessories or additional features that would enhance the power washing experience, please include that info as well. I'm looking for something robust and reliable, as it will need to handle exterior building cleaning tasks efficiently.
