Last updated on April 15th, 2024

The i series is one of the most loved vacuum robot series from iRobot. It is known for delivering the basic cleaning requirements at affordable prices. For this article, we are comparing the Roomba i4+ and i7+. Both have very similar features and thus leave people confused about which they should buy. Let’s demystify the facts and make an informed decision.

Which is better: Roomba i4+ vs. i7+?

The Roomba i7+ is a better choice due to its more promising navigation system and advanced mapping technology. It uses the iAdapt 3.0 navigation system, which is not present in the i4+. Both the models map your house, but the i7+ does it better. It will also allow you to set no-go zones in your home. So we prefer the i7+.

The Roomba i4+ uses an array of sensors to get around. It has a higher battery capacity and longer runtime than many of its counterparts. It can map your house while navigating but cannot store that information for further use. The i4 is still available for sale on the iRobot website. You can upgrade it to i4+ by buying a Clean Base docking station.

The Roomba i7+ uses iAdapt 3.0 Smart Mapping Technology to create a map of your home and provide targeted cleaning. With its dual multi-surface brushes and edge-sweeping brush, it effectively cleans various floor types.

The Clean Base docking station transfers the contents from the dustbin into a sealed vacuum bag on its own. It can hold debris from 30 cleaning cycles before requiring replacement.

Let’s discuss in detail how the two models are different from one another.

Roomba i4+ vs. i7+ Differences

There are two significant differences between these two models. One is the battery life, and the other is the navigation capabilities.

The Lithium Ion battery of the i4+ has a greater capacity of 2,210 mAh. Because of the higher capacity, it also takes more time to charge. It will take around 3 hours. Whereas the i7+ has a battery of the same composition but a lesser capacity of 1,800 mAh. It charges in 2 hours.

There’s also a significant difference in their runtime. The i4+, with its 100 minutes of runtime, is more capable of cleaning your house for less number of charges. The other model can run for 75 minutes, which is great if you have a small house.

The i7+ gives a better battery performance with an extra battery capacity of 400 mAh than the i4+.

Roomba i4+ vs. i7+ navigation

The i4+ did not have the smart mapping feature earlier. But according to an update from iRobot (dated January 2022), it is capable of smart mapping. Both models will also map your house and store the data for further use.

Both vacuums have cliff sensors that prevent them from falling down the stairs. But the iAdapt 3.0 Navigation system in i7+ sets the two apart. This makes it better capable of navigation and obstacle detection.

Both models are adaptable with virtual wall barriers that divert your vacuum from spots it should avoid. The i7+ mobile app also allows you to create virtual no-go zones on the app. But this feature is not available with i4+.

Considering that the i7+ uses a more advanced navigation system than the i4+ and has better map features, it is the better choice.

Roomba i4+ and i7+ similarities

Both models have similar designs, shapes, and sizes. They even have the same dustbin capacity. Since both models have an auto-emptying bin, you don’t have to worry about taking out the debris for weeks.

These models perform really well on carpets as well as hard floors. Their 3-Stage cleaning system ensures no spot is left uncleaned. Even the dirt detection technology in these models is worth appreciating. They will detect even minute particles and suction them into the bin.

What’s in the box?

You get the following accessories when buying these robot vacuums.

Both have all the same accessories besides a virtual wall barrier in the i4+ and an extra side brush in the i7+.

Conclusion

The Roomba i4+ gives a better battery performance. But it has an outdated navigation system. The latter’s iAdapt 3.0 navigation system surpasses the i4+. You will also notice that the mapping system of i7+ is more advanced and offers more features.

Considering everything, we recommend going for the i7+ as it is an upgraded version available at a minute difference in price.
