Troubleshooting Guide: What to Do When Your Roomba i7 is Not Charging

Table of Contents


With the increasing demand for convenience in everyday tasks, Roomba i7 has become an integral part of many households. This robotic vacuum cleaner boasts advanced features designed to maximize convenience and automate the often dreary process of home cleaning. However, like all technologies, certain issues may arise, with one of the most common complaints being charging issues. Understanding the root cause and arming yourself with the knowledge to troubleshoot these problems is a game-changer. And that is exactly the purpose of this guide on ‘Roomba i7 not charging.’

Understanding the Charging Mechanism of Roomba i7

Explanation about its Charging System

In its simplest form, the charging process of the Roomba i7 occurs when the device returns to its Home Base for scheduled or manual charging. Once docked, the device utilizes its built-in lithium-ion battery to stock power for the next cleanup session.

Differences between Roomba i7’s Charging System and Other Robotic Vacuums’ Charging Systems

While most robotic vacuum cleaners follow a similar base charging process, the Roomba i7 stands out with its smart charging feature. Unlike many standard models, the Roomba i7 calculates the amount of charge needed based on its cleaning schedule, ensuring it only charges as much as necessary to complete the job.

Details about the Charger Requirements

The charger of the Roomba i7 requires a standard 120V outlet, and the device must remain plugged in between cleaning sessions for optimal performance. It’s important to make sure that the charger, the Home Base, and the outlet are all in good condition to ensure successful charging.

Common Problems related to Roomba i7 Not Charging

Reasons why Roomba i7 might not be Charging

Several factors can contribute to your Roomba i7 not charging. These range from easy-fix issues like accumulated debris on charge contact points, insufficient power supply, or a problematic Home Base, to more complex issues like a defective internal battery.

Specific Examples of Charging Failure Cases

Many users report cases where the Roomba i7 fails to dock properly or doesn’t start charging even when placed on the Home Base. Other examples include cases where the device charges intermittently or not at all, indicating potential internal or base issues.

Importance of Diagnostics

Conducting diagnostics is critical to pinpoint the problem accurately. Doing simple checks such as inspecting the charging contacts for potential dirt accumulation, or checking the power supply, can often provide immediate insights into the issue.

Troubleshooting Methods to Fix the Charging Issue

Basic Troubleshooting Steps

Start with the basics. Ensure the Home Base is connected properly and getting sufficient power. Remove any debris from the charging contacts on both the Roomba and the Home Base. Finally, try resetting the Roomba by holding the clean button for about 10 seconds until the device powers off and then restart.

Advanced Troubleshooting Steps

For more persistent problems, carry out advanced checks like verifying the functionality of the charging unit by attempting to charge a different device. If all else fails, the internal battery could be the culprit. There are licensed professionals available to check and replace these parts if necessary.

When to Seek Professional Help

If the basic and advanced troubleshooting methods don’t resolve the issue, it’s likely time to involve professionals. They have the requisite knowledge and tools to diagnose and fix the problem effectively and safely.

Tips for Avoiding Charging Issues in the Future

Routine Maintenance Advice

Keep the charging contacts and Home Base clean from dust and other debris. Also, make a habit of regularly updating the Roomba’s software to ensure optimal operation.

Recommended Usage Habits

Avoid overloading your Roomba i7 with excessive cleaning schedules. Overusing the device can deplete the battery faster and impact the overall shelf-life of the appliance.

Purchasing Guideline for Roomba i7 chargers

Always purchase Roomba i7 chargers from trusted sources. Using non-original or cheap quality chargers can have adverse effects on the device and possibly cause charging issues.

Key Things to Remember

Always ensure your Roomba i7 is correctly docked and the charging contacts are clean. Regularly check the power supply and Home Base condition, and employ DIY troubleshooting methods when problems arise. However, avoid any fixes that require opening the device if you’re not trained to do so.


While the Roomba i7 is a smart and robust device, it occasionally may encounter charging problems. In many cases, these issues are simple to fix with the right knowledge and techniques. Remember to always practice routine maintenance and proper usage habits to extend its lifespan.
