Which is better: Roomba i7 vs. j7?

Roomba i7 and j7 are very similar to each other. But the Roomba j7 has better battery life. Unlike the Roomba i7’s top-facing camera, the j7 has a front-facing camera. Due to that detection of hazards becomes more feasible. Because of these enhanced features, the Roomba j7 is the better choice.

The Roomba i7 is a powerful robotic vacuum cleaner that was first launched in 2018. Its dual multi-surface brushes and edge-sweeping brush can effectively pick up dirt and debris from various floor types.

Its standout feature lies in its iAdapt 3.0 Smart Mapping Technology. It allows it to create a map of your home for more efficient cleaning.

Roomba i7 vs. j7 Comparison

Let’s discuss the points of comparison in more detail.

Differences between Roomba i7 and j7


IRobot has discontinued the Roomba i7 since it launched the Roomba j7. Being one of the newest and high-end models, the j7 is priced at $599. You can buy it from iRobot’s official website. But you will only find refurbished models of the i7 online. They are sold on Amazon for as low as $399.

Note: Their price keeps varying from seller to seller, as does the condition of the refurbished model. You can check out the price of the Roomba i7 directly on Amazon. It is definitely cheaper than the j7.

If you are on a budget and the refurbished model seems fine, opt for the Roomba i7, as it also gives a very similar performance to the j7. But if you want a brand-new robot, go for the Roomba j7.

Which model has a better battery capacity?

The i7 has a battery capacity of 1800 mAh, which is a bit less than the j7’s 2210 mAh battery. Owing to the greater battery capacity, the j7 also has a longer runtime of 100 minutes.

But the i7 can run only for 75 minutes on a full charge. Despite the different capacities, both models take around 3 hours for a complete recharge.

Having higher runtime and better battery capacity makes the Roomba j7 an ideal choice for cleaning.

Hazard Detection: Roomba i7 vs. j7

Hazard detection is one fantastic feature you will only find in Roomba j7. j7, with its front-facing camera, tries to detect potential hazards during its cleaning routine. A hazard could be a pile of clothes, pet poop, or even your pet trying to toy with the Roomba.

It immediately sends a notification on your mobile app. This notification contains a hazard alert along with a photograph of the hazard. This way, you know if something is coming in the course of your cleaning cycle.

With a hazard detection feature, the Roomba j7 outranks the Roomba i7 in terms of navigation.

Camera Position

Both Roomba i7 and j7 have a camera that they use for navigation and obstacle detection. The only difference is in their positioning. The Roomba i7’s camera is mounted on the top, while in the j7, it is mounted on the front of the vacuum. Having a front-facing camera has its advantages. It does a better job of identifying the obstacles as it gets a broader view of its surroundings.

Since the camera positioning of the Roomba j7 is better than the Roomba i7, it gives an edge in detecting obstacles.

Overall Design

The Roomba i7 and j7 are almost the exact sizes. Their designs are pretty different, though. The j7 has a silver circle on the top, whereas the i7 has a silver top with a small black-colored section. We personally find the i7 more attractive. But we are not looking at attractiveness, are we? We want the one that will satisfy our needs.

Similarities between Roomba i7 and j7

There are ample similarities between these models. The most evident one is their same dustbin capacities. So they can store an equal amount of waste. Actually, their waste collection ability is also similar as they have the same suction power and airflow. They even use the same 3-stage Cleaning System and Dirt Detection Technology. If you compare their cleaning performance, you won’t find much difference.

Surprisingly, the j7 uses the same iAdapt 3.0 Smart Mapping and vSLAM Navigation Technology as the i7. But it is still better at navigation and obstacle detection.


Roomba i7 and Roomba j7 will give you similar cleaning performance. However, the navigation capabilities of the Roomba j7 are much enhanced than those of the i7. It also has a better runtime so that it can clean more area in a single charge. Otherwise, both models have similar specifications and functionality. But we would recommend getting the j7 for its extra features.


Does Roomba j7 have mapping?

Yes, Roomba j7 has Smart Mapping technology that can memorize the map of your room and store it in its memory for future cleaning cycles.

Does Roomba i7 have a self-emptying dustbin?

Roomba i7 does not have a self-emptying dustbin, but it can be upgraded by buying a Clean Base. A ‘Clean Base’ is a docking station that can suck out the debris from your Roomba i7.
