Product Details

Powerful performance. Powerful pickup.
The Edge-Sweeping Brush works continuously while the Dual Multi-Surface Rubber Brushes flex to adjust to different floor types, loosening and lifting dirt. It’s all combined with Power-Lifting Suction that pulls in stubborn dirt, debris, and pet hair from wherever it hides.

Automatically empties its bin on it's own for up to 60 days.
Cleans up after itself, emptying its Vacuum Bin into an enclosed bag that holds up to 60 days of debris, which means two whole months of not thinking about vacuuming.

Focuses on dirt.
Proprietary Dirt Detect™ Technology allows the Roomba Combo® i3/i3+ robot to detect dirtier areas of your home and clean them more thoroughly when the Vacuum Bin is installed.

Neat rows for a more thorough clean.
Advanced navigation and 2 cleaning passes allows Roomba Combo® robot to navigate your home in neat, efficient rows for a wall-to wall clean without missing a spot. With overlapping passes, your robot purposefully & logically cleans in parallel lines across multiple floor types.

Vacuum and mop your hard floors simultaneously.
Simply attach the Roomba Combo® Bin and it will automatically sense it's time to vacuum and mop hard floors. Use the iRobot Home App or your voice assistant² to skip rooms with rugs or carpets.

A mop pad designed for performance.
Designed for wet floor mopping performance, the specialized microfiber pad tackles footprints, dirt and dust.

Cleans the rooms you want, when you want.
Learns your home and creates an Imprint® Smart Map so you can direct it to clean any room you want, any time you want—either on a set schedule or in the moment.

Clean your way more efficiently.
Fill the Roomba Combo® Bin's tank with a compatible cleaning solution³ of your choice or just water and instantly transform your robot into a vacuuming and wet mopping robot that leaves your home fresh and clean.

Cleans where you tell it to clean.
Simply pair Roomba Combo® i3/i3+ robot vacuum & mop with Alexa, Siri or Google Assistant-enabled devices² and tell it to clean the kitchen, living room, or every room.

For proper setup & operation
The Roomba Combo® i3/i3+ robot requires a 2.4 GHz network for setup and operation. After setup, keep your robot on 2.4GHz for operation; your phone can return to 5GHz.

FAQs
A: Yes, you can customize your clean in two different modes by swapping the bins: vacuum only using the dry bin or vacuum and mop your hard floors by inserting the Roomba Combo™ cleaning bin.
A: Imprint® Smart Mapping technology describes the robot’s ability to learn, map and adapt to your home. It learns your floorplan as it cleans and remembers this map for future cleaning jobs. Once the robot has learned your space you can tell it which rooms to clean and your robot will know which cleaning method to use based on the bin installed.
A: Yes, Cleaning crumbs is now as easy as “Roomba, clean under the kitchen table.” A simple request to your voice assistant* or via the iRobot Home App enables the Roomba Combo™ i3/i3+ robot vacuum and mop to clean messes for you, right when they happen—immediately clean that spot and consider it done. *Works with Alexa, Siri, and Google Assistant-enabled devices.

A. The Clean Base® Automatic Dirt Disposal eliminates the dusty and dirty mess often associated with emptying vacuum bins. This system’s Dirt Disposal bags hold 60 days of dirt and debris. Please note: Automatic Dirt Disposal not available when Mopping Bin is installed.
A. The Roomba Combo™ i3/i3+ robot instantly switches from vacuum to vacuum and mop mode when you install the Roomba Combo™ bin. If the bin is installed for mopping, carpets should be rolled up or removed from the room to keep them clean and dry—or use your voice assistant** or iRobot Home App to only clean rooms without rugs or carpets. Note: When the Roomba Combo™ Bin is being used, the Roomba i3/+ will always vacuum and mop simultaneously. If you wish to just vacuum for all floor types remove the Roomba Combo Bin™ and install the dry bin for vacuuming. **Works with Alexa, Siri, and Google Assistant-enabled devices.
