When the mop is being cleaned, dirty water will accumulate in the cleaning tray if it cannot be pumped out of the cleaning tray and into the dirty water tank. If you notice your robot's Auto-Clean Station is leaking water, please remove the robot from the Auto-Clean Station and inspect the Auto-Clean Station for water leakage by following the steps described in this article.

Determine the root cause of the water leakage:

Scenario 1: The cleaning tank of the cleaning tray is full of water, and the water overflows down the slope in front of the cleaning tray;

Scenario 2: The cleaning tank of the cleaning tray does not have water, and the slope in front of the cleaning tray is also dry. However, the water is leaking out from the bottom of the cleaning tray and around the Auto-Clean Station.

To troubleshoot Scenario 1, please refer to the following steps:

• Please confirm whether you have used non-eufy cleaning solution (it is highly recommended to use only either pure water or eufy cleaning solution that is specifically for the X9 Pro and other compatible eufy robot models).

• Please check whether there is any residue on the cleaning tray, because leftover residue on the cleaning tray can cause water to overflow when the Auto-Clean Station is washing the robot's mopping pads. If this is the case, please remove the cleaning tray from the Auto-Clean Station and wash the cleaning tray thoroughly.
• Please check whether the lid on the dirty water tank is completely closed and whether the dirty water tank is damaged, which can cause the lid to fail to close properly. If the dirty water tank is not completely closed, please close the dirty water tank tightly, reinstall the dirty water tank, and press it down slightly; if you find that the seal or lid buckle of the dirty water tank is damaged, or there are other physical damages, you will need to replace the dirty water tank with a new one.

To troubleshoot Scenario 2, please refer to the following steps:

• Please check the bottom of the cleaning tray (inside the Auto-Clean Station) to verify whether there is a small amount of residual water. If this is the case, the residual water in the cleaning tray may have leaked out while the cleaning try was being removed from the Auto-Clean Station. Please simply use a soft cloth to wipe the cleaning tray dry. Afterward, observe whether there is any water leakage as the robot resumes its normal operation. Additionally, when you disassemble the cleaning tray at a later time, please make sure to try and hold it horizontally in order to minimize the possibility of accidentally spilling water from the cleaning tray.

• Please remove the cleaning tray and inspect whether the rubber plug of the water-filling port of the cleaning tray is missing. If you find that the drain plug of the cleaning tray is missing, the cleaning tray will need to be replaced. （The picture on the left shows that the rubber stopper is in place, and the picture on the right shows that the rubber stopper is missing.）

• If you remove the cleaning tray and the water inlet plug is not missing, the cleaning tray may be the cause of water leakage and it needs to be replaced.
