Before you activate the mode, make sure the robot is ready for wet cleaning. Skipping this stage is the main reason why Dreame F9 Ignoring the command or making a mistake.
Here's what you have to do:
- 🔋 Charge the robot to 100 percent. Wet cleaning consumes more energy than dry cleaning. If the charge is below 20 percent, the device will block the mode.
- 💧 Set up a water tank. It comes with a set and it's attached to the back of the tank under the lid. Make sure the tank is firmly in place, and it's going to click.
- 🧽 Attach a wet wipe. Use only original or certified fabric nozzles. Paper towels or homemade rags can damage the mechanism.

Also check the cleanliness of the contacts between the tank and the housing. Dust or moisture on the connectors can cause E10 error (water supply system malfunction).
