The Roomba 690 is a powerful tool for maintaining a clean home, but its reliance on Wi-Fi connectivity means that sometimes technology can get in the way. One of the most common and frustrating issues owners face is the “No Robot Detected” error in the iRobot Home app. This message can appear unexpectedly, preventing you from starting cleaning cycles, setting schedules, or accessing any of the robot’s smart features, effectively turning your smart vacuum into a manual one.
This guide is designed to walk you through the entire process of resolving this connection problem. We will delve into the primary causes, from simple Wi-Fi signal issues to more complex software and hardware glitches. You will learn a systematic, step-by-step approach to troubleshooting, starting with the easiest fixes and moving toward more advanced solutions like a factory reset. By following these steps, you can diagnose the root cause of the error and restore the seamless connection between your phone and your Roomba 690.
Diagnosing the “No Robot Detected” Error
Before you can fix the problem, it helps to know what might be causing it. The “No Robot Detected” error is typically rooted in one of three areas: your network, the iRobot app, or the robot’s physical hardware. Pinpointing the source is the first step toward a quick resolution.
Wi-Fi and Network Problems
Your home Wi-Fi network is the bridge between your smartphone and your Roomba. If that bridge is weak or configured improperly, the connection will fail.
- Signal Range and Interference: The Roomba 690 may simply be too far from your Wi-Fi router to maintain a stable connection. Physical obstructions like thick walls, metal furniture, or other electronic devices can also interfere with and weaken the signal.
- Router Configuration: Not all Wi-Fi setups are ideal for IoT devices. The Roomba 690 performs best on a 2.4 GHz Wi-Fi band, which offers better range and wall penetration than the 5 GHz band. Furthermore, your router’s security settings can play a role; the recommended protocol is WPA2. Older protocols like WEP or WPA may cause compatibility issues.
- Outdated Firmware: Both your router and your Roomba rely on firmware to operate correctly. If either device is running on outdated firmware, it can lead to communication failures and connectivity bugs.
Application and Software Glitches
Sometimes, the problem isn’t with the robot or the network but with the software used to control it. The iRobot Home app is a complex piece of software that can experience its own set of issues.
- Outdated App Version: Running an old version of the iRobot app can lead to compatibility problems, especially after your robot’s firmware has been updated.
- App Conflicts: Other applications running in the background on your smartphone can occasionally interfere with the iRobot app’s ability to communicate over the network.
- Account Syncing Issues: A simple error with your login credentials or a temporary glitch in your iRobot account can prevent the app from recognizing a robot that is otherwise properly connected to the network.
Hardware and Physical Factors
The robot itself can be the source of the connection error. Physical issues can directly impact its ability to power on its Wi-Fi radio and communicate.
- Low Battery: A low or depleted battery can prevent the Roomba’s Wi-Fi module from functioning correctly, even if other parts of the robot seem to work. The device prioritizes core functions when power is low.
- Docking Station Malfunction: The Home Base is more than just a charger; it’s the robot’s home. If the dock is damaged, not properly connected to a working power outlet, or has dirty charging contacts, the Roomba may not charge correctly, leading to battery-related connection problems.
- Dust and Debris: A Roomba’s job is to collect dirt, but sometimes that dirt can cause problems. An accumulation of dust and debris on the robot’s sensors, in its filters, or near its internal components can potentially interfere with the Wi-Fi antenna’s performance.
Inherent Device Limitations
It is also important to recognize some of the Roomba 690’s built-in operational behaviors. The “Clean,” “Stop,” and “Home” buttons are intentionally designed to be non-functional while the robot is physically on its charging dock. This is a design choice, not a defect. To use these buttons, you must first remove the robot from the charger. This behavior can sometimes be mistaken for an error, but it is a normal part of the device’s operation and is not something that can be changed with a software update.
A Comprehensive Guide to Resolving Connection Issues
Follow these troubleshooting steps in order to systematically identify and fix the “No Robot Detected” error. Start with the simplest solutions first before moving on to more involved steps like a factory reset.
Step 1: Basic Checks and Resets
Begin with the fundamentals. These simple actions resolve a surprising number of tech issues.
- Check Wi-Fi Range: Move the Roomba and its Home Base closer to your Wi-Fi router, at least temporarily, to see if the connection stabilizes. If it does, a weak signal is likely the culprit.
- Restart Everything: Power cycle your devices. Unplug your Wi-Fi router from the wall, wait 30 seconds, and plug it back in. While the router is rebooting, restart your Roomba by pressing and holding the “Clean” button for about 10-20 seconds until it plays a reboot tone.
- Ensure a Full Charge: Place the Roomba securely on its Home Base and allow it to charge completely. A solid green light on the charger and a fully illuminated battery icon on the robot indicate a full charge. A low battery is a common cause of connectivity failure.
If your Roomba’s battery is consistently low or not holding a charge, it might be time to replace it. A healthy battery is crucial for proper Roomba function, including Wi-Fi connectivity.

Step 2: Optimizing Your Network
If basic resets don’t work, the issue may lie within your Wi-Fi network’s configuration.
- Analyze Your Wi-Fi Environment: Use a Wi-Fi analyzer app on your smartphone to check for signal strength and channel interference in the area where your Roomba normally operates.
- Confirm Router Settings: Log in to your router’s administration panel. Ensure your network is broadcasting a 2.4 GHz band and that your Roomba is connected to it, not a 5 GHz band.
- Verify Security Protocol: While in your router settings, check that the security protocol is set to WPA2.
- Disable Advanced Security: Temporarily disable any advanced security features like MAC address filtering, which could be preventing the Roomba from joining the network. If this solves the problem, you can add your Roomba’s MAC address to the approved list.
- Check for Firmware Updates: Look for a firmware update option within your router’s settings and install any available updates.
Step 3: Managing the iRobot Home App
A glitchy app can be the source of the problem. Refreshing it can often restore the connection.
- Update the App: Go to your phone’s app store (Google Play Store or Apple App Store) and check for updates to the iRobot Home app. Install the latest version.
- Close Background Apps: Fully close all other apps running in the background on your phone to prevent potential conflicts.
- Re-authenticate Your Account: Log out of the iRobot Home app completely. Then, log back in using your correct credentials. This can often resolve account-syncing issues.
- Reset App Settings: If available in your phone’s settings, you can try clearing the app’s cache or resetting it to its default state.
Step 4: Performing a Roomba Reset
A reset can clear out internal software bugs that may be causing the connection failure. There are two primary ways to do this.
Resetting Through the iRobot App
If you can still access some settings for the robot in the app, this is the easiest method.
- Open the iRobot Home app and select your Roomba.
- Navigate to Product Settings.
- Find and select the “Reboot Roomba” option.
- The robot will take several minutes to restart. Ensure it remains on the Home Base with sufficient battery power throughout the process.
Performing a Manual Device Reset
This method, often called a factory reset, is more thorough and can be done even if the app isn’t working at all.
- Press the “Clean” button to wake the robot up.
- Press and hold the “Clean” button for about 10-20 seconds. The lights will turn off.
- Continue holding the button until the lights turn back on and you hear a reboot sound.
- After the reset is complete, you will need to go through the Wi-Fi setup process again using the iRobot Home app to reconnect the robot to your network.
Step 5: Inspecting Physical Components
Physical blockages or poor connections can mimic software errors.
- Clean the Robot: Turn the Roomba over and thoroughly clean the brushes, extractors, and filter. Use a cloth to wipe down the sensors and charging contacts on both the robot and the Home Base. Check for any debris that might be physically blocking the area where the internal Wi-Fi antenna is located.
- Inspect the Docking Station: Ensure the Home Base is plugged firmly into a working power outlet. Check its power cord for any signs of damage. Try plugging it into a different outlet to rule out electrical issues.
