The R85 has a slightly taller profile than some other robot vacuums but is still designed to fit under most furniture. Both vacuums are well-built for their price range, but the Shark ION R85 may have a slight edge in terms of overall sturdiness.
Performance Face-Off
Cleaning Performance on Hard Floors
- Roomba 690: The Roomba 690 performs adequately on hard floors, effectively picking up loose dirt and debris. However, it can sometimes struggle with finer particles, and its edge cleaning performance is not the best, leaving some debris along walls and in corners.
- Shark ION R85: The Shark ION R85 excels on hard floors, thanks to its powerful suction and multi-surface brushroll. It effectively captures both large and small debris and boasts better edge cleaning capabilities than the Roomba 690.
Cleaning Performance on Carpets
- Roomba 690: The Roomba 690 is decent at cleaning low-pile carpets but struggles with high-pile carpets. It may have difficulty climbing onto thicker carpets and lacks the suction power needed for deep cleaning.
- Shark ION R85: The Shark ION R85 shines on carpets, especially with its “Max” mode. Its strong suction and self-cleaning brushroll effectively remove dirt, debris, and pet hair from both low and high-pile carpets.
Pet Hair Removal
- Roomba 690: The Roomba 690 can pick up some pet hair, but it is not its strong suit. It may struggle with larger clumps of hair and can sometimes leave strands behind.
- Shark ION R85: The Shark ION R85 is a pet hair cleaning powerhouse. Its powerful suction and self-cleaning brushroll efficiently remove pet hair from all floor types, making it an excellent choice for pet owners.
Navigation and Obstacle Avoidance
- Roomba 690: The Roomba 690 uses a random navigation pattern, which can sometimes result in missed spots or inefficient cleaning paths. However, it is generally good at maneuvering around furniture and obstacles.
- Shark ION R85: The Shark ION R85 also uses random navigation but is equipped with sensors that help it avoid obstacles and navigate around furniture. It may bump into objects more forcefully than the Roomba 690.
Special Features Comparison
- Roomba 690:
- Wi-Fi Connectivity: Allows for app control, scheduling, and voice control via Amazon Alexa or Google Assistant.
- Virtual Wall Barrier: Creates an invisible barrier to keep the Roomba from entering specific areas.
- Shark ION R85:
- Wi-Fi Connectivity: Similar to the Roomba, it enables app control, scheduling, and voice control.
- Self-Cleaning Brushroll: Actively removes hair wrap, ensuring consistent performance and reducing maintenance.
- BotBoundary Strips: Physical strips that can be placed on the floor to block off areas.
- 3X Suction in Max Mode: Provides extra power for tackling stubborn dirt and pet hair.
Usability and User Experience
The iRobot Roomba 690 is known for its simple and intuitive user experience. Its one-button operation makes it easy to start a cleaning cycle, and the iRobot app is user-friendly and straightforward. The Roomba 690 is a great choice for novice users who want a hassle-free cleaning experience.
The Shark ION R85 also offers a good user experience, but it may require a bit more setup and customization. The Shark app is comprehensive and provides a range of control options, but it may be slightly less intuitive than the iRobot app. The R85’s BotBoundary strips are effective for blocking off areas but require manual placement, which may be less convenient than the Roomba’s virtual wall barrier.
Maintenance and Longevity

Both the iRobot Roomba 690 and Shark ION R85 require regular maintenance to ensure optimal performance. This includes emptying the dustbin, cleaning the brushroll, and replacing filters as needed. The Roomba 690 has fewer parts that need regular cleaning, which may make it slightly easier to maintain. However, the Shark ION R85’s self-cleaning brushroll reduces the frequency of manual brushroll cleaning.

Final Recommendation
The Shark ION R85 emerges as the stronger contender in this comparison.

Its powerful suction, self-cleaning brushroll, and quiet operation make it a compelling choice for a wide range of users. The Roomba 690 remains a decent option for those who prioritize ease of use and maneuverability, but the Shark ION R85 offers more bang for your buck in terms of cleaning power and features.
