Cleaning Performance & Navigation
The Roomba i3 delivers effective cleaning through a methodical navigation pattern, covering floors efficiently. It utilizes a floor tracking sensor to navigate your home, cleaning in neat rows. Dirt Detect™ Technology focuses cleaning efforts on visibly dirtier areas, providing targeted power where it’s needed most.
The i3’s dual multi-surface brushes effectively capture both large debris and fine dust. For i3+ models, Imprint™ Smart Mapping learns your home’s layout, enabling customized cleaning schedules and targeted zone cleaning. This ensures a thorough and intelligent cleaning experience.

Dirt Detect™ Technology Explained
Dirt Detect™ Technology employs an acoustic sensor to identify concentrated areas of dirt and debris on your floors. When the Roomba i3 detects a higher concentration of particles, it automatically adjusts its cleaning behavior. It will spend more time focusing on that specific spot, ensuring a more thorough clean.
This intelligent system doesn’t rely on visual detection; instead, it “hears” the dirt. The Roomba i3 will repeatedly pass over heavily soiled areas until the sensor indicates sufficient cleaning has occurred, providing a noticeably cleaner result in high-traffic zones.
Imprint™ Smart Mapping (if applicable ‒ i3+)
Imprint™ Smart Mapping, available on the i3+ model, learns your home’s layout to enable customized cleaning experiences. The Roomba i3+ creates an intelligent map, allowing you to direct the robot to clean specific rooms or zones via the iRobot Home App.
This feature also facilitates the creation of Keep Out Zones, preventing the Roomba from entering areas you wish to avoid. Imprint™ technology remembers multiple floor plans, making it ideal for multi-level homes, and optimizes cleaning routes for efficient coverage and targeted cleaning.
Maintaining Your Roomba i3
Regular maintenance is crucial for optimal performance and longevity of your Roomba i3. This includes frequently emptying the dustbin after each cleaning cycle, or when the indicator light signals it’s full. Equally important is the routine cleaning of the brushes – both the multi-surface rubber brushes and the edge-sweeping brush – removing any hair, debris, or tangled fibers.
Inspect the brushes for wear and tear, replacing them as needed. Periodically check and clean the sensors to ensure accurate navigation. Following these simple steps will keep your Roomba i3 running efficiently.
Emptying the Dustbin

Tap the dustbin gently to dislodge any trapped dirt and debris. For a more thorough clean, use a dry cloth to wipe the inside of the dustbin. Avoid using water or cleaning solutions. Reinstall the dustbin securely, ensuring it clicks into place. A full dustbin significantly reduces cleaning effectiveness.
Cleaning the Brushes (Multi-Surface & Edge-Sweeping)
Maintaining clean brushes is crucial for optimal Roomba i3 performance. Regularly inspect the multi-surface rubber brushes and the side edge-sweeping brush for tangled hair, fibers, and debris. To remove the brushes, release the brush frame and lift them out.
Remove any obstructions by hand or use the included cleaning tool. Ensure the brushes spin freely after cleaning. For the edge-sweeping brush, simply remove and clear any tangled material. Reinstall all brushes securely, ensuring proper alignment for effective floor coverage and cleaning.
