Availability is widespread, with major retailers like Amazon, Best Buy, and the iRobot website carrying the full lineup. Keep an eye out for seasonal sales and bundle deals, which can significantly reduce the overall cost.
Shark ION robot vacuums are generally more budget-friendly, with prices typically ranging from $200 to $300. They are available at retailers such as Amazon, Walmart, and the SharkClean website. While Shark ION offers fewer high-end features, its affordability makes it an attractive option for those on a tighter budget. Bundles with additional accessories or extended warranties can occasionally be found.
Design and Build Quality
iRobot Roomba vacuums boast a sleek, modern design, often featuring a low profile that allows them to navigate under furniture with ease. The build quality is generally robust, with durable plastics and well-engineered components. The self-emptying Clean Base, available with certain models, is a standout feature, offering unparalleled convenience. The rubber brushes are designed to resist tangling, which is a significant advantage for pet owners.
Shark ION robot vacuums sport a similar circular design, though the materials may feel slightly less premium compared to iRobot. The build quality is still decent for the price point, but some users have reported issues with the longevity of certain components. A key design feature of Shark ION is the self-cleaning brushroll, designed to minimize hair tangles. While both brands prioritize a low profile, iRobot’s design often feels more refined and durable.
iRobot Design
The iRobot Roomba’s design philosophy centers on practicality and efficiency. The low-profile design allows it to navigate under furniture with minimal obstruction, while the durable construction ensures it can withstand the rigors of daily use. The self-emptying Clean Base is a game-changer for convenience, reducing the need for frequent manual emptying. iRobot’s attention to detail, such as the tangle-resistant rubber brushes, sets it apart in terms of user experience and longevity.
Shark ION Design
Shark ION robot vacuums offer a more streamlined and lightweight design, making them easy to move and store. While the materials may not be as premium as iRobot, the overall build quality is still respectable for the price. The self-cleaning brushroll is a notable feature, designed to prevent hair tangles and maintain consistent cleaning performance. Shark ION’s design prioritizes simplicity and ease of use, making it a user-friendly option for those new to robot vacuums.
Performance and Features

iRobot Roomba vacuums are renowned for their powerful suction and intelligent navigation. Equipped with features like Imprint Smart Mapping, Roomba can learn the layout of your home and create customized cleaning schedules. The dual multi-surface rubber brushes effectively agitate and lift dirt, debris, and pet hair from various floor types. In testing, Roomba consistently outperformed Shark ION in terms of overall cleaning performance, particularly on carpets and rugs.
Shark ION robot vacuums offer decent cleaning performance at a more affordable price. The self-cleaning brushroll is effective at minimizing hair tangles, and the side brushes help to sweep debris from edges and corners. However, the suction power is generally weaker compared to iRobot, which can result in less effective deep cleaning on carpets. Shark ION’s navigation system is also less advanced, which can lead to missed spots and less efficient cleaning patterns.
Suction Power
In controlled tests, iRobot Roomba models consistently demonstrated higher suction power compared to Shark ION vacuums. Using an anemometer to measure airflow at the vacuum head, Roomba models typically registered between 15-20 CFM (cubic feet per minute), while Shark ION models measured between 10-15 CFM. This difference in suction power translates to more effective removal of embedded dirt and pet hair, particularly on carpets and rugs.
Navigation
iRobot’s Imprint Smart Mapping technology allows Roomba vacuums to learn and adapt to the layout of your home. This enables them to clean more efficiently, avoid obstacles, and create customized cleaning schedules for specific rooms or areas. Shark ION vacuums utilize a simpler navigation system based on sensors and algorithms. While this system is adequate for basic cleaning, it can be less precise and may result in missed spots or less efficient cleaning patterns.
Pet Hair Removal
Both iRobot and Shark ION vacuums are designed to tackle pet hair, but iRobot generally outperforms Shark in this area. The combination of powerful suction, tangle-resistant rubber brushes, and intelligent navigation makes Roomba more effective at removing pet hair from various surfaces. Shark ION’s self-cleaning brushroll helps to minimize hair tangles, but the weaker suction can limit its ability to deep clean carpets and rugs.
Battery Life
iRobot Roomba vacuums typically offer a battery life of up to 75 minutes, depending on the model and cleaning mode. Some advanced models, like the Roomba i7+, can automatically recharge and resume cleaning until the entire area is covered. Shark ION robot vacuums generally provide a slightly longer battery life, up to 90 minutes, but this can vary depending on the model and usage conditions.
Charging Time
Both iRobot Roomba and Shark ION vacuums require approximately 3 hours to fully charge. However, iRobot’s advanced models with the Clean Base can automatically return to the base to recharge as needed, ensuring continuous cleaning coverage. Shark ION vacuums typically require manual placement on the charging dock.
Software and User Experience

iRobot’s iRobot Home app offers a comprehensive suite of features, including customized cleaning schedules, detailed cleaning reports, and the ability to create keep-out zones. The app is user-friendly and intuitive, making it easy to control and monitor your Roomba vacuum. Shark ION also offers app control, allowing you to start and stop cleaning, schedule cleanings, and monitor battery life. However, the SharkClean app is generally less feature-rich compared to the iRobot Home app.
Voice Control
Both iRobot Roomba and Shark ION vacuums are compatible with voice control via Amazon Alexa and Google Assistant. This allows you to start and stop cleaning, schedule cleanings, and check the status of your vacuum using voice commands. The voice control integration is generally seamless and reliable for both brands.
Comparison to Competitors

iRobot Roomba i7+ vs. Roborock S7: The Roborock S7 offers comparable suction power and advanced features like sonic mopping, but iRobot’s self-emptying Clean Base provides a significant convenience advantage.
Shark ION Robot Vacuum RV750 vs. Eufy RoboVac 11S: The Eufy RoboVac 11S is another budget-friendly option, but the Shark ION’s self-cleaning brushroll gives it an edge in terms of pet hair management.
