Roomba 671 Vs I3: Differences
The Roomba i3 clearly prevailed in this showdown with the Roomba 671, with a final score of 3-0 to a 1-all draw. Explore the key differences between these two remarkable robot vacuum cleaners.
Cleaning performance
The winner: Roomba I3
Hardwood floor
When comparing the performance of the Roomba 671 vs i3 on hardwood floors, the i3 is the clear winner in terms of efficiency. The i3 utilizes advanced floor tracking sensors to navigate in straight, neat rows, ensuring a more logical and purposeful cleaning experience. In contrast, the 671 moves randomly, which can sometimes result in missed spots or redundant cleaning.
Both robot vacuums have powerful, fast-spinning side brushes that effectively clean edges and remove debris and dust. However, they also tend to scatter larger debris on hard floors, which can actually prolong the cleaning process. While both models are capable of picking up small, light items like rice, crumbs, and cereal, they struggle with larger debris, which is a limitation to keep in mind.
Carpets
| Roomba I3 | Roomba 671 | |
|---|---|---|
| Low-pile Carpet | ≈ 95% | ≈ 91% |
| High-pile Carpet | ≈ 89% | ≈ 85% |
Both the Roomba i3 and the Roomba 671 perform best on low-pile carpets, moving seamlessly across the surface and picking up large amounts of dirt and debris. However, they both struggle with smaller particles, like sand. On medium-pile carpets, the i3 demonstrates superior suction efficiency, removing approximately 89% of dirt, while its performance is even better on low-pile carpets, with a 95% efficiency rate.
While the 671 performs relatively well, its overall performance is slightly lower than that of the i3. Despite this, the 671 still stands out as one of the better options available in its price range. One of the standout features of the i3 is its ability to seamlessly transition from hard floors to carpets, as well as its inclusion of a cliff sensor, which helps prevent the vacuum from falling down stairs.
Hair test
The Roomba i3 takes the lead over the Roomba 671, proving to be more effective and efficient in picking up pet hair while minimizing tangling. The i3’s superiority in handling pet hair can be attributed to its advanced brush roll system architecture, which features two rubberized brush rolls. These squeegee rolls are adept at lifting larger debris and finer particles, such as pet hair and dust, from various floor types while simultaneously preventing tangles.
In comparison, the Roomba 671 is equipped with a bristle brush and a feather duster. While the bristle brush is effective at dislodging dirt and debris from carpets, it may not be as proficient at capturing pet hair as the i3’s upgraded brush system. Therefore, for pet owners or those dealing with significant amounts of hair, the Roomba i3 is the recommended choice.
Design and Usability
The winner: Roomba I3
Dimensions & Weight
The dimensions and weight of the Roomba 671 vs I3 are fairly comparable, both featuring a compact and low-profile design that is conducive to cleaning in tight spaces and convenient for storage. The Roomba i3 has a diameter of 13.26 inches, a height of 3.63 inches, and weighs 7.44 pounds. On the other hand, the Roomba 671 has similar dimensions but is slightly heavier, weighing approximately 7.8 pounds.
These machines’ compact size and low profile are significant advantages, as they can easily navigate under furniture and other tight spaces where dirt and dust tend to accumulate, all while taking up minimal storage space when not in use. In this category, the difference in weight is minimal and is unlikely to significantly impact your choice between the two models.
Navigation
The Roomba i3 is significantly superior to the Roomba 671. The 671 relies on stochastic response navigation, utilizing sensors to detect obstacles and dirt as it moves around the home. While this method can be effective in smaller rooms, it tends to be less efficient in larger areas and may miss spots, especially around wooden furniture. It’s also worth noting that the 671 must collide with walls and objects to change direction, which can result in a fair amount of noise.
In contrast, the Roomba i3 is equipped with advanced vSLAM and iAdapt 2.0 navigation technology, which greatly enhances its ability to map out and navigate cleaning areas. The top-mounted camera of the i3 allows it to create a visual map of the area, helping it to recognize furniture and other obstacles and subsequently clean in straight, efficient rows. This technology gives the i3 a clear edge in terms of navigation and overall cleaning efficiency.
Battery
Both the Roomba 671 vs I3 are equipped with lithium-ion batteries known for their high energy density and long life. However, there is a notable difference in their battery life. The Roomba i3 offers up to 75 minutes of cleaning time on a full charge, whereas the Roomba 671 surpasses that with a runtime of up to 90 minutes.
However, the disparity in battery life is not a significant concern, as both robots feature self-recharging capabilities. This means that when the battery starts running low, the vacuum will return to its docking station to recharge and resume cleaning from where it left off. This feature ensures that your cleaning task is not left incomplete due to a depleted battery.
Additionally, both the Roomba 671 vs I3 have a battery indicator, which makes it easy to monitor the battery status and know when it’s time to recharge. This feature is particularly useful when you are managing the vacuum through a smartphone application, as it allows you to keep track of the cleaning progress and battery life from anywhere.
Control
Tie!
Both the Roomba 671 vs i3 feature physical controls on the device itself, which allow for easy manual control of the vacuum’s various functions, such as spot cleaning, power, and docking. Moreover, both robots can be controlled remotely through the iRobot application via a Wi-Fi network. This application is incredibly user-friendly and offers several valuable features, such as scheduling cleaning sessions, viewing cleaning history, receiving battery level notifications, and remotely navigating the robot. You can even set the vacuum to clean while you’re away from home.
An additional advantage of these devices is their compatibility with home assistants like Amazon Alexa and Google Assistant. This compatibility enables users to control the vacuum with voice commands, making it convenient to start or stop a cleaning session without having to lift a finger. The integration of these features and functionalities in both the Roomba 671 vs i3 ensures a convenient and hassle-free cleaning experience for users.
Cleaning & Maintenance
The winner: Roomba I3
Both the Roomba 671 vs i3 have comparable cleaning and maintenance requirements. They have been designed with user convenience in mind, featuring brush rollers and castor wheels that are simple to disassemble for regular cleaning and inspection.
However, there are some differences between the two models when it comes to dustbin capacity and filtration systems. The Roomba 671 has a relatively small dustbin with a capacity of approximately 0.3 liters, while the i3 has a slightly larger bin capable of holding up to 0.4 liters of debris. For those with pets, especially those with long fur, the larger dustbin of the i3 may be preferable, as it won’t fill up as quickly, resulting in less frequent emptying.
Regarding filtration, the Roomba i3 has a slight edge as it utilizes a highly effective HEPA filter to capture microscopic dust particles and allergens. This makes the i3 a great option for pet owners and individuals with allergies or asthma. In contrast, the Roomba 671 uses a standard filter, which is less effective at trapping finer particles.
