We’ve tried out using a drone to clean up the outside of Rushcroft Court.
The multi-storey block, in Blackley, had seen a build-up of algae on its exterior in the last five years.
Shifting it usually involves getting a mast climber or scaffolding equipment, which can be quite expensive.
That’s why, this time, we turned to Aspira Aerial Applications to trial their drone technology.
They removed the algae by flying the drone with a remote control and spraying it with a treatment liquid.
Here’s a clip of the machine in action:
The treatment works gradually, with the appearance improving in the days and weeks after the wall is sprayed.
Here’s what the building looked like before and after treatment:
Northwards’ project surveyor Mark Watson said: “We’re always on the look-out for new and innovative ways of improving our properties, so we were excited to work with Aspira and try this out. It’s more cost-effective than the traditional methods and, as you can see from the photos, produces great results. We’ll definitely be considering using this approach again in future.”
