Is your iRobot Roomba 870 acting up? Don’t worry, you’re not alone. The Roomba 870 is a reliable cleaning companion, but like any robot, it can sometimes run into snags. This article provides a comprehensive guide to diagnosing and resolving common Roomba 870 issues, so you can get your trusty robot vacuum back to work keeping your floors spotless.
Understanding Common Roomba 870 Problems
The Roomba 870, while a workhorse, can experience a variety of issues. Recognizing the symptoms is the first step toward fixing them. These can range from simple errors like a full bin to more complex problems with the robot’s sensors or motors. By understanding these common problems, you’ll be better equipped to troubleshoot and resolve them efficiently.
Troubleshooting Steps for Your Roomba 870
Here’s a breakdown of common issues and how to address them:
1. Roomba Won’t Turn On or Charge
- Check the Power: Ensure the Home Base is plugged in and the power light is illuminated.
- Clean the Charging Contacts: Wipe the charging contacts on both the Roomba and the Home Base with a clean, dry cloth.
- Battery Check: If the Roomba still doesn’t charge, the battery might be the issue. Remove the battery and check its voltage with a voltmeter. A fully charged Roomba 870 battery should measure around 14.4 volts DC. If the voltage is significantly lower, the battery may need replacing.
- Let it Charge: Allow Roomba to charge on the Home Base for at least 3 hours.
2. Roomba Not Picking Up Dirt
- Empty the Bin: The most common reason for poor cleaning performance is a full dustbin. Empty it after each use.
- Clean the Filter: A clogged filter restricts airflow. Clean the filter regularly by removing it and tapping it against a trash can to dislodge debris. Replace the filter every few months for optimal performance.
- Inspect the Extractors: The Roomba 870 uses tangle-free extractors instead of brushes. Check these for hair, string, or other debris.
1. Pinch the extractor frame release tabs.
2. Lift the extractor frame and remove any obstructions.
3. Clean the caps and around the metal axles.
4. Remove hair and debris from the square and hexagonal plastic pegs.
5. Clear the vacuum path. - Check the Vacuum Path: Make sure there are no blockages in the vacuum path itself.
3. Roomba Gets Stuck or Encounters Obstacles
- Clear the Area: Remove any small objects, cords, or loose rugs that could trap the Roomba.
- Use Virtual Walls: Utilize the Virtual Wall barriers to block off areas where the Roomba frequently gets stuck.
- Clean the Cliff Sensors: The Roomba uses cliff sensors to avoid falling down stairs. If these sensors are dirty, they may misread the floor as an edge. Wipe the sensors with a clean, dry cloth.
4. Roomba Won’t Return to Home Base
- Ensure Clear Path: Make sure there is a clear path between the Roomba and the Home Base.
- Home Base Placement: The Home Base should be placed on a level surface against a wall, with ample clear space around it.
- Check the Bumper: The bumper needs to register obstacles correctly. If the bumper is compressed or the bumper sensor is dirty, the Roomba may have trouble docking.
5. Error Messages
- Understanding Error Messages: The Roomba 870 communicates issues through error messages, often accompanied by a voice narration and/or a blinking troubleshooting indicator.
- Common Error Codes and Solutions:
* Error 1: Move Roomba to a new location and press CLEAN. This indicates the Roomba is stuck or a wheel is hanging down.
* Error 2: Open Roomba’s extractor frame and clean the extractors. This means the extractors cannot turn.
* Error 5: Spin Roomba’s side wheels to clean. A side wheel is stuck.
* Error 6: Move Roomba to a new location and press CLEAN. The cliff sensors are dirty, or Roomba is stuck on a dark surface.
* Error 9: Tap Roomba’s bumper to clean. The bumper is compressed, or the bumper sensor is dirty.
* Error 1-4: Re-install Roomba’s bin, then press CLEAN to restart. Roomba is not detecting an installed bin.
* Error 1-8: Roomba cannot return to the Home Base or starting position.
Practical Tips for Maintaining Your Roomba 870
- Regular Cleaning: Empty the bin and clean the filter after each cleaning cycle.
- Scheduled Maintenance: Replace the filter every 2-3 months, and the extractors every 6-12 months, depending on usage.
- Battery Care: If you won’t be using your Roomba for an extended period, remove the battery and store it in a cool, dry place.
FAQ
What do I do if my Roomba 870 keeps getting stuck in the same spot?
Use a Virtual Wall barrier to block off that area. It’s also a good idea to inspect the area for potential hazards like loose cords or uneven surfaces.
How often should I replace the Roomba 870’s filter?
For optimal performance, replace the filter every 2-3 months. If you have pets or allergies, you may need to replace it more frequently.
Can I use my Roomba 870 on dark carpets?
Dark surfaces can sometimes interfere with the cliff sensors, causing the Roomba to think there’s a drop-off. If your Roomba is having trouble on dark carpets, try cleaning the cliff sensors or using a Virtual Wall to prevent it from entering those areas.
My Roomba 870 is making a strange noise. What should I do?
Inspect the extractors and wheels for any tangled debris. If the noise persists, it could indicate a problem with the motor. Contact iRobot customer support for further assistance.
How do I know when to replace the battery on my Roomba 870?
If your Roomba’s run time has significantly decreased, and it’s no longer cleaning for as long as it used to, it’s likely time to replace the battery.
