Underwater drone - maintenance and cleaning of the device

Did you know that up to 95% of underwater drone complaints are caused by improper drone maintenance? Unclean propellers fail to spin due to presence of foreign matter in engines. In this guide, we explain what cleaning should look like underwater drone after each use.

Underwater drone - special maintenance after use

Cleaning your underwater drone after each dive is extremely important. Otherwise, salt water and sand particles will cause blockage of engines and propellers. In addition, in the long term, there is a corrosion process and electrolysis phenomenon that destroys components and causes corrosion of copper connections.

Underwater drone - watch out for corrosion!

The higher the salinity and pollution of the water in which the drone dived - the more important it is to carry out such cleaning. Keep in mind that the conditions in which your underwater drone operates may be different, so you may need additional maintenance on the device.

Cleaning instructions using an underwater drone as an example Chasing M2

Step one

Fill a large container with fresh water. It can be any tank that can accommodate your underwater drone. It is important that it is fully submerged. Make sure the water is fresh and clean. Make sure there were no previously harmful substances in the container, such as chemicals.

This example uses a plastic box from a local hardware store.

Step two

When the box is filled to the desired height, prepare the drone and place it in the container. Make sure all wires are submerged.

Leave the unit in the water for 10 - 15 min., to let the water soak into all the places.

Step three

Once you have allowed the device to soak the appropriate time, you can unlock its motors. Once the drive starts, the underwater drone will submerge to the pre-dive level.

Leave the drone in this position for another 10-15 minutes. Note, if the drone will not submerge to the point where it is completely covered by water, submerge it with the controller.

Then steer the drone in different directions, several times, so that the propellers spin in both directions.

Step four

When the drone is thoroughly rinsed, dry it from the remaining water.

Place the drone on a clean, straight surface where it is safe for the motors to spin.

If you have made sure that nothing will disturb the motors, turn on the drone and let them spin. This will allow the water to dry.

Let the motors spin for a few minutes, or until you see that water is not coming out of them.

You can also spray the engines with a suitable preparation/lubricant when the engines are running.

Step five

This is the time to dry the drone to the end. You can use a device for this, such as a small blower. This allows the propellers to spin using air and to dry out the body of the drone.

Dry each motor from 30s to 1 min, then clean the connectors and apply the appropriate preparation to all moving parts of the drone as well as the screws that are exposed.

Store the dried drone in a case and keep it tightly sealed.
