When it comes to high-performance robot vacuums, the Roomba 985 and iRobot Roomba i7 are two models that consistently deliver exceptional cleaning results, advanced navigation, and smart features. Although both fall under iRobot’s premium line, they cater to different needs and preferences. This detailed comparison will help you decide which model is better suited for your home, based on their cleaning capabilities, smart features, navigation systems, and more.
Design and Build Quality
Size, Weight, and Appearance
The Roomba 985 and i7 share similar design aesthetics, with a sleek, round body and a black finish with silver trim. Both are compact and designed to fit easily under furniture, though the i7 has a slightly more modern appearance with a more refined overall finish.
| Feature | Roomba 985 | Roomba i7 |
|---|---|---|
| Dimensions | 13.4 x 3.6 inches | 13.3 x 3.7 inches |
| Weight | 8.7 lbs | 7.44 lbs |
| Finish | Black with Silver Trim | Black with Silver Trim |
The difference in size and weight is minimal, but the i7 is slightly lighter, making it easier to handle and store. Both models maintain the same diameter, so they fit easily under most furniture, but the i7’s slightly smaller height makes it slightly better at fitting into more cramped spaces.
Cleaning Performance
Suction Power and Brush System
Both the Roomba 985 and i7 are equipped with iRobot’s AeroForce® 3-Stage Cleaning System, which includes Dual Multi-Surface Brushes, a high-efficiency filter, and strong suction capabilities. However, there are subtle differences in suction power and cleaning efficiency between the two models.
| Cleaning Aspect | Roomba 985 | Roomba i7 |
|---|---|---|
| Suction Power | Very High | High |
| Brush System | AeroForce® Dual Brushes | AeroForce® Dual Brushes |
The Roomba 985 has a slightly higher suction power compared to the i7, making it more efficient at picking up debris from deep carpets, pet hair, and larger dirt particles. While the i7 offers solid suction, the Roomba 985 is better for homes with thicker carpets or more intense cleaning needs.
Performance on Various Surfaces
| Surface Type | Roomba 985 Performance | Roomba i7 Performance |
|---|---|---|
| Hardwood Floors | Excellent | Excellent |
| Low-Pile Carpets | Excellent | Excellent |
| High-Pile Carpets | Excellent | Good |
Both vacuums are excellent on hardwood floors and low-pile carpets. However, the Roomba 985 excels in homes with high-pile carpets, offering superior suction for deep cleaning. The Roomba i7, while good on carpets, doesn’t quite match the 985’s performance on thicker rugs.
Navigation and Mapping
iAdapt 2.0 vs Smart Mapping Technology
The Roomba 985 uses iAdapt® 2.0 Navigation with Visual Localization, which maps out rooms and cleans in systematic rows, ensuring more efficient coverage. While this is a significant upgrade over older models, the Roomba i7 takes it a step further with more advanced Smart Mapping technology.
| Navigation Feature | Roomba 985 | Roomba i7 |
|---|---|---|
| Navigation System | iAdapt® 2.0 with Visual Localization | Smart Mapping |
| Smart Mapping | Yes | Yes |
| Obstacle Avoidance | Advanced | Advanced |
The i7 features smarter, more precise mapping. It not only memorizes the layout of your home but also allows you to select specific rooms for cleaning. This level of customization is a standout feature that gives the i7 more control over your cleaning schedule.
Cleaning Customization:
| Customization | Roomba 985 | Roomba i7 |
|---|---|---|
| Room Selection | No | Yes (with app) |
| Zone Cleaning | No | Yes (with app) |
The Roomba i7’s Smart Mapping allows you to define specific zones for the robot to clean, making it much more customizable compared to the 985, which lacks this feature. This is particularly useful if you want to clean particular rooms or areas without disturbing others.
Battery Life and Runtime
Run Time and Recharge and Resume
Both the Roomba 985 and i7 offer up to 120 minutes of continuous cleaning, and both models support the “Recharge and Resume” feature. If the battery runs low during cleaning, the robots will automatically return to their charging dock, recharge, and resume cleaning from where they left off.
| Battery Aspect | Roomba 985 | Roomba i7 |
|---|---|---|
| Runtime | ~120 minutes | ~120 minutes |
| Recharge and Resume | Yes | Yes |
The battery life is virtually identical, but the i7 has an edge when it comes to its efficiency. The i7’s smart sensors allow it to clean more effectively with fewer recharges, making it better suited for larger homes or longer cleaning sessions.
Smart Features
App Control and Voice Integration
Both models feature Wi-Fi connectivity and can be controlled via the iRobot Home app. Additionally, both are compatible with Amazon Alexa and Google Assistant, allowing for voice control. However, the i7 offers more advanced features within the app.
| Feature | Roomba 985 | Roomba i7 |
|---|---|---|
| Wi-Fi Compatibility | Yes | Yes |
| App Control | Advanced | Advanced |
| Voice Commands | Alexa/Google | Alexa/Google |
The Roomba i7 offers more granular control within the app, including room-specific scheduling, advanced cleaning reports, and custom cleaning zones. It provides a more seamless and customized experience compared to the Roomba 985, which has fewer options for cleaning preferences.
Maintenance and Accessories
Dustbin Capacity and Filter System
Both the Roomba 985 and i7 feature a high-efficiency filter and a similarly sized dustbin, making maintenance easy. They both require regular emptying of the dustbin and occasional cleaning of the brushes.
| Maintenance Aspect | Roomba 985 | Roomba i7 |
|---|---|---|
| Dustbin Capacity | 600 ml | 600 ml |
| Filter Type | High-Efficiency | High-Efficiency |
Despite their similarities, the Roomba i7 comes with the additional Clean Base® Automatic Dirt Disposal feature, which allows it to empty its dustbin automatically into a larger bag in the base. This is a significant advantage for those looking for a truly hands-free experience, especially for larger homes or busy households.
Price and Value
| Aspect | Roomba 985 | Roomba i7 |
|---|---|---|
| Price Range | High | Higher |
| Value for Money | Excellent | Excellent |
The Roomba i7 is typically priced higher than the Roomba 985 due to its advanced features such as Smart Mapping, room-specific cleaning, and the Clean Base® Automatic Dirt Disposal. While the Roomba 985 provides excellent value for its price, the i7 offers a more premium experience with a higher level of automation and customization.
