Symptoms & Diagnosis

Start here when your robot vacuum behaves unexpectedly but does not show a clear error code. A symptom such as “will not dock,” “brush stopped,” or “mop is dry” can have several causes, and the right check depends on the robot and its dock.

Choose a starting point

• How to troubleshoot a robot vacuum: start with these checks — identify what changed, separate the robot from its dock, and choose a safe first check.
• Robot vacuum will not turn on — distinguish a sleeping, uncharged, or model-specific first-use state from a fault.
• Robot vacuum is offline or will not connect — separate initial setup from a lost connection or temporary offline state.
• Robot vacuum will not charge, dock, or return home — separate a navigation problem from a charging or dock-power problem.
• Robot vacuum will not empty into the dock — check the cleaning state and dust path before assuming the station has failed.
• Robot vacuum missed a scheduled clean or will not resume — check schedule conditions and model-specific resume rules.
• Robot vacuum map is incomplete or distorted — check mapping conditions and saved-map behavior before rebuilding a map.
• Robot vacuum brush is not spinning or picking up — check for a jam or installation issue, then look at airflow and other causes of weak pickup.
• Robot vacuum or dock is making a loud noise — locate the sound by task and identify what still works before checking a part.
• Robot vacuum mop is dry or no water reaches the pad — distinguish a dry pad from a robot-side or dock-side water problem.
• DEEBOT X5 OMNI White wets carpet during mopping — see the exact product’s explanation and map-boundary option.
• DEEBOT X5 PRO OMNI mop pad plate will not retract — follow ECOVACS Canada’s model-specific setting and obstruction checks.
• Robot vacuum is leaking water — identify the leaking tank or cover and stop safely if water reaches electrical parts.
• Robot mop dock tray overflows or will not drain — use the station-specific tray and wastewater checks without opening the dock.
• Robot vacuum says the bin is full when it is empty — follow the exact bin and sensor-cleaning guidance for the robot model.
• Robot vacuum mop pad smells — check drying and follow the instructions for the exact pad and model.
• Robot vacuum stops, gets stuck, or misses areas — separate an obstruction or mobility issue from an expected route or map behavior.

Before you troubleshoot

Find the robot’s full model name or number and identify the dock or base station that came with it. Record your country, the cleaning mode and surface, any app message or light pattern, and whether the issue began after moving the dock, cleaning the robot, changing a part, or updating the app. These details can change which checks apply.

Change one low-risk condition at a time and observe the result. A robot that cannot find a dock has a different problem from one that reaches the dock but does not charge. A dry mop pad does not by itself prove that a pump has failed, and weak pickup does not prove that the brush needs replacing.

Stop when a check is no longer routine

Use the manufacturer’s instructions for the exact model. Do not open a battery pack, sealed motor, pump, dock, or internal electrical assembly; bypass a cliff or other safety sensor; or keep testing a leaking, hot, damaged, or electrically suspect machine. Disconnect power only when it is safe to do so, then contact the manufacturer or a qualified service provider.

These guides help narrow a symptom. They do not establish universal part compatibility. Confirm the exact robot, dock, region, and part number before buying a replacement.
