Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →If your Roomba will not dock, first determine which problem you have: it cannot find the dock, reaches it but misses the contacts, docks without charging, or docks and then loses charge. Check the dock’s power and placement, clean the contacts and sensors, clear the approach, then reboot the robot and inspect the battery. These steps solve many docking problems without replacing the robot or dock.
Start with the symptom
- It never finds the dock: suspect dock placement, an obstructed route, a moved base, or a navigation problem.
- It reaches the dock but bumps, turns away, or misses: check alignment, the bumper, dock sensors, and charging contacts.
- It sits on the dock but does not charge: check power, contact cleanliness, battery installation, and battery condition.
- It docks and then loses charge: suspect intermittent contacts, the battery, or the dock’s power supply.
“Won’t dock” and “docks but won’t charge” are related but different faults. iRobot’s Error 18 guidance generally concerns returning to the dock or starting position, while charging errors such as 4, 5, 21, 119, and 121 can indicate contact, battery, dock, or power problems. Error codes vary by model family.

1. Check the dock’s power and position
- Unplug the dock from the wall and, if detachable, from the dock itself.
- Reconnect both ends firmly.
- Test the wall outlet with another device.
- Confirm that the dock has not been moved, rotated, or knocked out of position.
- Place it on a hard, level surface against a wall.
- Clear the approach and keep the dock at least 4 feet (1.2 metres) from stairs, following iRobot’s placement guidance.
A thick rug, uneven floor transition, cable, shoe, pet toy, furniture edge, or table leg can interfere with the final approach. If the dock was recently moved, the robot’s stored map or expected starting position may no longer match it.
When in doubt, move the dock to another suitable location and start a new cleaning run from the dock. This creates a controlled test instead of repeatedly sending the robot toward a problematic position.

2. Clean the charging contacts and sensors
Dirty contacts are one of the quickest and cheapest causes to eliminate.
- Remove the Roomba from the dock.
- Unplug the dock and wait 60 seconds.
- Turn the robot over on a flat surface.
- Lightly dampen a melamine foam pad or soft cloth.
- Wipe the metal charging contacts on both the robot and dock until they look shiny.
- Where applicable, wipe the dock’s sensor window with a clean, dry microfiber or soft cotton cloth.
- Reconnect the dock and place the robot squarely on it.
- Wait for the robot to indicate that it is charging.
This follows iRobot’s charging-contact procedure and its sensor-cleaning guidance. Do not spray cleaner onto the robot or dock, soak the cloth, or scrape the contacts with a sharp metal tool. iRobot recommends regular contact cleaning, including weekly cleaning in its Home Base placement guidance.
Inspect the contacts while cleaning. Green or copper-coloured discoloration, stuck-down contacts, deep damage, or corrosion may mean the part is damaged rather than merely dirty. In that case, the robot or dock may need replacement.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errors3. Clear the approach and test navigation
Inspect three areas:
Around the dock
Remove cords, baskets, toys, clutter, furniture edges, and anything that could block the robot’s approach or cause it to turn away. Check that the dock is still straight and firmly positioned.
On the robot
Remove stickers, tape, or paint from the bumper and dock-facing surfaces. Press the bumper gently to confirm that it moves freely. Also check the wheels and steering area for debris.

In the app or map
If your model supports mapping, check whether the dock was moved after the map was created. Use the app’s return-to-dock command where available. If it repeatedly fails, relocate the dock and begin a new run from the dock.
Do not assume every Roomba navigates or reports errors in the same way. Older models, camera-based robots, LiDAR models, Essential products, and newer Combo products use different hardware and may show different codes. iRobot notes that Error 18 does not apply to every product family; some LiDAR docking problems may instead report Error 1010.
4. Reboot the Roomba and check the battery
Only move to battery checks after power, placement, contacts, and obstructions have been addressed.
Reboot from the app
For models supported by the Classic iRobot HOME App, use Product Settings → Reboot Roomba → Reboot Roomba. Labels can differ by product generation or app version, so look for the reboot control in your robot’s product settings if this path is not identical.
Reseat the battery
On models with an accessible battery, removing and reinstalling it can clear some charging problems. The procedure differs by model, so do not assume one screw layout applies to every Roomba.

For older 700-, 800-, and 900-series battery compartments, iRobot’s published procedure is:
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Remove the two battery-door screws.
- Remove the door and battery.
- Reinstall the existing or replacement battery with its label and tabs facing up.
- Replace the door and two screws.
- Make sure the side brush is not pinched during reassembly.
See the model-specific iRobot battery instructions before opening your robot.
If it docks but still will not charge
Manually place the robot squarely on the dock and check the result:
- Does the robot light up or beep?
- Does the charge percentage increase?
- Are both sets of contacts clean, shiny, and springing normally?
- Is the dock receiving power from the outlet?
- Is the battery correctly installed?
A dock indicator turning off does not necessarily prove that the dock is unpowered. iRobot says some dock lights switch off after a short time to conserve power, and behaviour varies by model. The manual-docking test is more useful: observe whether the robot indicates charging when correctly aligned.
Suspect the battery when the robot docks but the percentage never rises, dies immediately when removed from the dock, takes unusually long to charge, or continues reporting charging errors after the contacts and power supply are checked. A swollen or visibly damaged battery should not be used. iRobot recommends an authentic, model-matched battery because aftermarket batteries can cause unknown charging errors.

When the dock, battery, or robot may need replacement
Contact iRobot or consider a replacement part when:
- The dock remains unpowered after outlet and cord checks.
- The robot does not light up or beep when manually aligned on the dock.
- Contacts are corroded, discoloured, stuck, or physically damaged.
- The robot repeatedly loses charge despite clean contacts and a correctly installed battery.
- A known-good compatible battery does not solve the problem.
- The problem began after liquid exposure, an impact, or damage to the power cord.
Do not assume any Roomba dock will work with any Roomba. Home Base, Clean Base, AutoEmpty, AutoWash, and AutoFill products have different designs and compatibility requirements. Verify the exact robot model before buying.
For warranty or expedited support, have the robot, serial number, and proof of purchase available. Use the official iRobot support hub when the correct replacement part is unclear or a persistent charging error remains.
Official replacement docks and batteries can be appropriate when the robot is otherwise healthy, but buying a Clean Base or another major component after one failed docking attempt is premature. Cleaning, repositioning, and removing an obstruction should come first. A new robot becomes a value decision when the existing robot is old, several components are failing, compatible parts are unavailable, or repair costs approach the robot’s value.
Quick diagnostic path
| Symptom | Check first | Then check |
|---|---|---|
| Cannot find the dock | Dock position, power, and clear route | Start from the dock, then test another suitable location |
| Reaches but misses the dock | Clutter, bumper, alignment, and dock sensors | Clean contacts and inspect for damage |
| Docks but does not charge | Manual alignment, power, and contacts | Reboot, reseat the battery, or test a compatible replacement |
| Docks then loses charge | Intermittent contacts and battery installation | Battery condition, dock, and power supply |
Because model families differ, check the support page for your exact product before applying a model-specific reset, battery procedure, or error-code diagnosis.
