Are you tired of spending your precious time vacuuming? The Roomba i3 robot vacuum offers a convenient, hands-free solution to keep your floors clean. But how exactly does this little robot navigate and clean your home? This article will delve into the inner workings of the Roomba i3, exploring its technology, cleaning process, and helpful features.
How the Roomba i3 Efficiently Cleans
The Roomba i3 is designed to efficiently clean your home using a combination of smart navigation, powerful suction, and intelligent features. It takes the chore of vacuuming off your hands, letting you focus on more important things. Let’s explore how the Roomba i3 works.
Smart Navigation and Mapping
The Roomba i3 uses floor tracking sensors to navigate your home in neat, straight rows. Unlike some higher-end models that use cameras, the i3 relies on these sensors to “feel” its way around. This allows it to efficiently clean an entire level of your home, even in complete darkness.
How Imprint Smart Mapping Works
After a few cleaning runs, the Roomba i3 creates an Imprint Smart Map of your home, learning the layout and identifying different rooms. You can then customize this map in the iRobot Home app, labeling rooms and setting cleaning schedules.
Cleaning in Neat Rows
The Roomba i3 cleans in straight, back-and-forth lines, ensuring thorough coverage of your floors. This systematic approach is more efficient than random bouncing, which is used by some cheaper robot vacuums.
Powerful Cleaning System

The Roomba i3 boasts a 3-Stage Cleaning System, combining multiple features to effectively lift dirt, dust, and debris from your floors.
Dual Multi-Surface Rubber Brushes
The i3 uses dual rubber brushes that are uniquely designed with rubber treads that stay in constant contact with different floor surfaces – from hard floors to carpets – adjusting and flexing, to get everything from small particles like dust and dirt, to hair and large debris.
Edge-Sweeping Brush
The Roomba i3 also has a specially designed Edge-Sweeping Brush to get into corners and along walls.
Power-Lifting Suction
The Roomba i3 offers 10X the Power-Lifting Suction compared to the Roomba 600 series, ensuring strong pickup performance.
Obstacle Avoidance and Smart Features
The Roomba i3 is equipped with several features to help it avoid obstacles and clean your home more effectively.
Reactive Sensor Technology
Reactive Sensor Technology helps the Roomba i3 avoid getting stuck on furniture and other obstacles. It detects areas where it cannot pass, ensuring it spends less time stuck and more time cleaning.
Dirt Detect Technology
iRobot’s Dirt Detect Technology allows the Roomba i3 to focus on dirtier areas, like high-traffic zones in your home. When the robot senses these areas, it cleans them more thoroughly.
Self-Emptying with Clean Base (i3+ model)
The Roomba i3+ model comes with a Clean Base Automatic Dirt Disposal system. This allows the robot to automatically empty its dustbin into a larger bag in the base, which can hold up to 60 days’ worth of debris.
Preparation Steps Before Using Roomba i3

Before using the Roomba i3, it’s recommended to do the following to ensure optimal performance:
- Clear the floors: Pick up any loose items like cords, toys, or clothing that could get in the way of the Roomba.
- Prepare the charging dock: Place the charging dock on a level surface with enough space around it for the Roomba to maneuver.
- Charge the Roomba: Allow the Roomba i3 to charge for at least three hours before its first use.
Troubleshooting Common Issues
Here are some common problems you might encounter with the Roomba i3 and how to solve them:
- Roomba not cleaning thoroughly: Ensure the brushes are clean and free of hair or debris. Also, check the filter and replace it if necessary.
- Roomba getting stuck: Clear any obstacles that might be trapping the Roomba, and use the iRobot Home app to set up virtual boundaries if needed.
- Roomba not docking properly: Make sure the charging contacts on the Roomba and the base are clean and free of debris.
- Roomba not connecting to Wi-Fi: Ensure your Wi-Fi network is working properly and that you have entered the correct password in the iRobot Home app.

Tips, Warnings, and Best Practices
- Regular Maintenance: Clean the brushes, filter, and sensors regularly to ensure optimal performance.
- “Robot-proof” your home: Clear any small objects or cords that could get tangled in the Roomba’s brushes.
- Use the iRobot Home app: Take advantage of the app’s features to schedule cleaning, customize maps, and monitor the Roomba’s progress.
- Empty the dustbin regularly: Even if you have the i3+ model with the Clean Base, it’s still a good idea to check the dustbin periodically and empty it if needed.
- Keep the charging contacts clean: Wipe the charging contacts on the Roomba and the base with a clean, dry cloth to ensure proper charging.
