Price Comparison
The Shark IQ Robot UR100S typically retails for around $300-$400, while the Roomba i8+ generally costs between $500-$700. The Shark offers a lower upfront cost, making it an attractive option for budget-conscious buyers. However, the Roomba’s advanced features and superior cleaning performance may justify the higher price for those prioritizing effectiveness and convenience. When evaluating the cost-to-feature ratio, consider your specific cleaning needs, the size of your home, and your tolerance for manual maintenance. If you’re primarily concerned with basic floor cleaning and don’t require advanced customization, the Shark IQ Robot UR100S provides excellent value. But if you need a more robust cleaning solution with smart features and better performance on various floor types, the Roomba i8+ is worth the investment.
Design and Build Quality

The Shark IQ Robot UR100S features a low-profile design that allows it to navigate under furniture and tight spaces easily. Its all-black finish and glossy control panel give it a sleek, modern appearance. The Roomba i8+ also has a compact design, but its two-tone gray finish and more refined details give it a more premium look.
In terms of build quality, the Roomba i8+ generally feels more robust and durable than the Shark IQ Robot UR100S [14]. The Roomba’s components, such as its rubber brushes and wheels, are made from higher-quality materials that can withstand long-term use. The Shark, while still well-built, may show signs of wear and tear sooner, especially with frequent use. Both robots are designed for easy maintenance, with removable parts that can be cleaned or replaced as needed. However, the Roomba’s self-emptying base with disposable dirtbags is generally easier to maintain than the Shark’s bagless system, which requires manual emptying and cleaning of the dustbin.
Performance Face-Off

Cleaning on Hard Floors
Both the Shark IQ Robot UR100S and the Roomba i8+ perform well on hard floors, effectively picking up dirt, dust, and small debris. However, the Roomba i8+ tends to excel at edge cleaning and getting into corners, thanks to its specialized edge-sweeping brush.
Cleaning on Carpets
The Roomba i8+ generally outperforms the Shark IQ Robot UR100S on carpets, particularly thicker pile carpets. The Roomba’s Power-Lifting Suction and dual rubber brushes provide more agitation and suction power, resulting in a deeper clean. The Shark IQ Robot UR100S can still clean carpets effectively, but it may require multiple passes to achieve the same level of cleanliness as the Roomba.
Pet Hair Removal
Both robots are designed to handle pet hair, but the Roomba i8+ has a slight edge in this category. Its dual rubber brushes are less likely to get tangled with pet hair, and its high-efficiency filter captures more allergens and dander. The Shark IQ Robot UR100S also features a self-cleaning brush roll to prevent hair tangles, but it may not be as effective as the Roomba’s system.
Navigation and Obstacle Avoidance
The Roomba i8+ uses iAdapt 3.0 navigation with vSLAM technology, which allows it to learn your home’s layout and clean efficiently. It can also detect and avoid obstacles such as furniture and pet bowls. The Shark IQ Robot UR100S uses IQ Navigation, which employs a row-by-row cleaning pattern. Some users have reported that the Shark IQ Robot UR100S can sometimes struggle with complex layouts or dark rooms, whereas the Roomba’s navigation is more reliable in various conditions [4, 14].
Special Features Comparison

The Roomba i8+ offers several unique features, including Keep Out Zones, which allow you to create virtual boundaries to prevent the robot from entering certain areas. It also has Clean Zones, which let you designate specific areas for targeted cleaning. The Imprint Link technology allows the Roomba i8+ to coordinate with other iRobot devices, such as the Braava jet m6 mopping robot, for a comprehensive cleaning solution.
The Shark IQ Robot UR100S features a self-cleaning brush roll that prevents hair tangles and a high-efficiency filter that captures dust and allergens. Its row-by-row cleaning pattern ensures thorough coverage, and its room selection feature allows you to clean specific rooms on demand. While it lacks some of the advanced features of the Roomba, the Shark IQ Robot UR100S provides a solid set of capabilities for automated floor cleaning.
Usability and User Experience
Both the Shark IQ Robot UR100S and the Roomba i8+ are designed for ease of use, but the Roomba often has a more seamless user experience. The iRobot HOME app is intuitive and easy to navigate, with clear instructions and helpful tips. The SharkClean app is also functional, but some users have reported occasional connectivity issues and a less polished interface.
The Roomba i8+ is particularly well-suited for novice users, thanks to its simple setup process and straightforward controls. The Shark IQ Robot UR100S may require a bit more initial setup and configuration, but it’s still relatively easy to use. Both robots offer voice control via Alexa and Google Assistant, allowing you to start, stop, or schedule cleaning sessions with voice commands.
Maintenance and Longevity
The Roomba i8+ requires minimal maintenance, thanks to its self-emptying base with disposable dirtbags. Simply replace the bag every 60 days or so, and clean the brushes and filters as needed. The Shark IQ Robot UR100S requires more frequent manual emptying and cleaning of the dustbin, as well as regular cleaning of the brush roll and filters.
In terms of longevity, the Roomba i8+ generally has a longer lifespan than the Shark IQ Robot UR100S, due to its higher-quality components and more robust construction. However, both robots can last for several years with proper maintenance and care. Be aware that both brands have reports of units failing after a year or so [9].
Who Should Buy the Shark IQ Robot UR100S?
The Shark IQ Robot UR100S is an excellent choice for:
- Budget-conscious buyers looking for a self-emptying robot vacuum at an affordable price.
- Users with smaller homes or apartments where advanced navigation isn’t as critical.
- Individuals who prioritize basic floor cleaning and don’t require advanced features or customization.
- Those willing to perform more frequent manual maintenance to save on upfront costs.
Who Should Buy the Roomba i8+?
The Roomba i8+ is the better choice for:
- Users who prioritize superior cleaning performance, especially on carpets and with pet hair.
- Individuals who want a more hands-free cleaning experience with minimal maintenance.
- Those who value advanced features and smart home integration.
- Allergy sufferers who will benefit from the enclosed dirt disposal bags.
- Homeowners with larger homes or complex layouts that require advanced navigation.
Final Recommendation
In summary, the Roomba i8+ represents a better overall value for users who prioritize cleaning performance, advanced features, and ease of use. Its superior navigation, powerful suction, and user-friendly app make it a top contender in the self-emptying robot vacuum market. However, the Shark IQ Robot UR100S remains a compelling option for budget-conscious buyers who want a basic self-emptying robot vacuum at an affordable price. If you’re willing to sacrifice some performance and features to save money, the Shark IQ Robot UR100S is a solid choice.
