Vacuum symptom guide
Why Will My Robot Vacuum Not Dock?
Docking trouble begins with one distinction: whether the robot cannot find or physically reach its base, or reaches and aligns but cannot charge, empty, wash, refill, dry, or communicate. Robot movement and sensors affect the approach, while base power, contacts, alignment hardware, accessories, and electronics affect dock operation.
Important distinction
A symptom is not a repair diagnosis
The same symptom can come from several assemblies. Use the evidence below to choose a repair path, then confirm the failed part and exact model compatibility before ordering.
Safety first
Stop and inspect before using it again
Unplug a damaged, wet, overheated, or electrically odorous dock. Do not bridge charging contacts, open its power supply, or test wet dock functions when liquid can reach a power connection.
Safe first checks
- Place the exact dock on a stable surface with the manufacturer-specified clearance and power connection.
- With the dock unplugged, clean dry external contacts and documented removable trays, bags, or paths.
- Confirm the robot-side contacts, wheels or tracks, sensors, and battery can complete one controlled approach.
Narrow the cause
What to observe before choosing a repair
Record these details without bypassing an interlock or opening a sealed electrical assembly. They help distinguish repair targets that can produce a similar symptom.
- Whether the robot finds the dock, reaches it, aligns, makes contact, and begins the expected function
- Any exact app message, spoken alert, base indicator, or charging pattern
- Whether wheel or track drag, low battery, or a dirty sensor prevents the final approach
- Whether charging works but a separate emptying, washing, refilling, drying, or communication function fails
Possible repair paths
Repairs that can fit this symptom
These are possibilities, not a definitive diagnosis. Select the repair whose evidence fits the exact machine and behavior.
Repair intake
Still not sure which repair fits?
Start with the make, exact model, photos, and what the vacuum is doing. Inspection confirms the failed assembly before final parts or repair decisions.
