Feature-by-Feature Breakdown
Navigation Technology
- Irobot S7: Utilizes vSLAM (Visual Simultaneous Localization and Mapping) technology with a gyroscope for systematic cleaning. It creates a map of your home, allowing for efficient and organized cleaning patterns. While good for most homes, it can occasionally struggle with very complex layouts or in low light.
- S9: Employs the advanced “Smart Mapping” system, which is an evolution of vSLAM. It offers more precise room recognition, the ability to name rooms, and set up custom cleaning zones or keep-out areas. This leads to more intelligent and personalized cleaning routines.
- Winner: s9
Suction Power
- Irobot S7: Features a high-efficiency filter and a decent suction power suitable for everyday debris. It effectively picks up dust, pet hair, and crumbs from various floor types. While good, it might require a second pass for deeply embedded dirt.
- S9: Boasts 40x the suction power of its predecessors, with a unique D-shaped design that allows it to get closer to edges and into corners. This superior suction is excellent for tackling stubborn dirt, larger debris, and deep-pile carpets.
- Winner: s9
Cleaning System
- Irobot S7: Equipped with a 3-Stage Cleaning System that uses dual multi-surface rubber brushes, an edge-sweeping brush, and powerful suction. The rubber brushes are good at adapting to different floor types and are less prone to tangling than bristle brushes.
- S9: Also features a 3-Stage Cleaning System, but with its signature D-shaped design, the cleaning head is wider and can cover more area. The dual rubber brushes are designed for deep cleaning, and the extended edge-sweeping brush effectively captures dirt along walls and in corners.
- Winner: s9
Edge and Corner Cleaning
- Irobot S7: The standard round design with an edge-sweeping brush does a decent job of reaching edges. However, it can sometimes miss the tightest corners due to its circular shape.
- S9: The revolutionary D-shaped design is specifically engineered to tackle edges and corners more effectively. Its extended cleaning head and optimized edge-sweeping brush allow it to reach into crevices that round robots often miss, providing a more thorough clean.
- Winner: s9
Smart Home Integration & App Control
- Irobot S7: Integrates with voice assistants like Alexa and Google Assistant. The iRobot Home app allows for scheduling, starting/stopping cleans, and viewing cleaning history. It offers basic control and customization.
- S9: Offers robust smart home integration with voice assistants. The iRobot Home app is more advanced, enabling users to create custom cleaning zones, set keep-out areas, and receive personalized cleaning suggestions based on room usage and seasonal needs.
- Winner: s9
Battery Life & Auto-Recharge
- Irobot S7: Provides a respectable battery life suitable for cleaning moderate-sized homes. It automatically returns to its charging base when the battery is low and can resume cleaning from where it left off.
- S9: Features a battery designed to cover larger areas. Like the s7, it offers auto-recharge and resume functionality, ensuring that even larger homes can be cleaned in a single session if needed.
- Winner: s9
Dirt Disposal
- Irobot S7: Collects dirt into its internal dustbin, which needs to be manually emptied. For enhanced convenience, it is compatible with the Clean Base Automatic Dirt Disposal system (sold separately).
- S9: Designed to work seamlessly with the Clean Base Automatic Dirt Disposal system (often bundled or available). This allows the robot to empty its own bin into a larger, disposable bag, significantly reducing the frequency of manual emptying.
- Winner: s9
Design and Build Quality
- Irobot S7: Features a classic round design with a premium finish. It’s built to be durable and handle the rigors of daily cleaning. The overall aesthetic is functional and understated.
- S9: Stands out with its unique D-shaped design, which is both aesthetically modern and functionally superior for edge cleaning. It is constructed with high-quality materials, giving it a premium feel and robust build.
- Winner: s9

Is the self-emptying feature worth the extra cost?
The self-emptying Clean Base is a significant convenience feature, especially for busy households or those with allergies. It allows the robot to empty its dustbin automatically into a larger bag within the base, meaning you only need to empty the base itself every few weeks. For many, this added convenience justifies the higher price.
Can both models handle different floor types effectively?
Yes, both the iRobot S7 and S9 are designed to transition between different floor types, such as carpets and hard floors. They automatically adjust their cleaning settings to optimize performance. However, the S9’s enhanced suction and brush design may offer a more thorough clean on carpets compared to the S7.
Which model offers better edge cleaning?
While both models aim for good edge cleaning, the S9’s more advanced navigation and its D-shaped design often give it a slight edge in reaching into corners and along walls more effectively than the S7’s more traditional round shape. This can result in a more comprehensive clean around the perimeter of rooms.
Final Verdict
The iRobot S7 offers excellent value for its price, providing a capable and convenient cleaning experience for everyday messes. However, for those seeking the absolute best in suction power, advanced navigation, smart features, and pet hair management, the iRobot S9 stands out as the superior choice.
