January 2026 In a firefighting and water-spraying drone test, a homemade WeeFeeS drone successfully achieved stable flight at an altitude of 4-5m. Improvements are ongoing.
We have successfully achieved stable flight of a window and exterior wall cleaning drone using Sky Robot’s DJI FLYCART30 and our water spray unit (our patented technology and three commercially available Karchers). The test was conducted with the cooperation of Sekido Kasukabe.
October 2025 We exhibited our aircraft at the Fire and Disaster Management Agency's booth at RISCON TOKYO, the Crisis Management Industry Exhibition 2025. We would like to thank everyone who attended and cooperated with us. The URL for the exhibition video is below. Here is the video shown at the exhibition!
August 2025 Water discharge test using an electric fire pump (details of the equipment, water discharge pressure, height, etc. are shown in the video).
Summer 2025 Sekido's DJI T10 equipped with our water spray unit.
Spring 2026 Continuous water spraying from indoor fire hydrant No. 1 (130 L/min) was successfully completed using a 40 mm diameter hose at an altitude of 6-7 m.
Winter 2025 A window cleaning test was successfully conducted using a commercially available Kärcher K2 battery-powered washing machine. The water was pressurized and pumped by a ground-based pump, and then sprayed.
What is WeeFeeS LCC?
WeeFeeS LLC uses new technology and drones to solve high-altitude work such as window cleaning, insulator cleaning of steel towers, painting at high places, and extinguishing fires that occur in high places where people cannot access.
