Roomba I6 vs. I7 Low-Noise Cleaning vs. Long-Lasting Cleaning

If you’re looking for robot vacuum cleaners, only a handful of manufacturers will provide such a wide selection of choices as iRobot, particularly with the Roomba line.

Our testing units are the i7 and the i6, and we will discuss our findings throughout this write-up.

There are some distinctions when you compare the Roomba I6 against the I7. While the i6 features an extra filter and an additional side-brush, the I7 lacks. 

In contrast, the Roomba i7, on the contrary, comes with a Halo mode that creates an invisible barrier for your device.

Both Roomba models, i6 and i7, utilize the iAdapt 3.0 technology, which allows them to sweep in a unidirectional direction while you clean your home.

1. Utilizing Space

iRobot Roomba i6+ 3

A further difference between the Roomba I6 and i7 lies in the amount of surface they can cover. While the i7 can clean around 2500 square feet of space, the I6 can clean up to 4000 square feet.

In this instance, both robots are distinguished due to their battery and runtime. The i6 runs for two hours, which is twice longer than the Roomba i7. 

2. Carpet Cleaning

Both vacuum cleaners from Robotics excel at cleaning floors and carpets. The Roomba I7 and i6 both have multi-surface brushes that make penetrating carpet fibers simple.

However, we would say that the i6, thanks to its larger filter and the brush, can clean carpets more thoroughly after a couple of rounds.

3. Noise Level

Both vacuum cleaners can be considered to have acceptable noise levels. If you test the i6 and the i7 Roomba and agree at around 58dB, the i6 is quieter in comparison to I7′ that generates 65dB.

Strangely enough, the i7 becomes louder once you have a full bin.

4. Suction & Dustbin Capacity

If you look at the Roomba I7 with the i6, you’ll see the difference in the capacity of the dust bin. The former can hold a capacity of 400 milliliters compared to the one that has 500 milliliters.

The i6’s garbage bin is bigger than the one on the i7. However, the i7 lets you clean the bin using bags, while the i6 empties its own.

The i6, as well as the i7, have a suction power that is 1800 Pa. However, we noticed that when the i7 takes in long hair, we are required to untangle the corner brush.

But the suction strength from both devices is sufficient to draw larger particles out instead of moving their way across the flooring.

5. Automatic Self Emptying

One benefit of the latest robot vacuums is that they have automatic self-emptying technologies. This means homeowners do not need to be concerned about alerts for the full bin.


iRobot Roomba i6+ 2

The iRobot Clean Base unit actually doubles in the capacity of a dock. After the robot vacuum has finished its cleaning process, it is docked, which is the point at which it is taken into AllergenLock bags, which can hold up to a month’s worth of dirt. The bags are supplied with two AllergenLock bags.


Roomba I7 2

In the Roomba I7 series, we have the self-emptying technology that is automatic. The model accepts technology. If Roomba docks, it is docked after cleaning the bin; the contents are then emptied into the bigger bin.

6. Battery and Power Management

A quality robot vacuum should come with a battery that can last at least one full cleaning session.

Additionally, it should come with power management features that are convenient. In this article, we’ll learn what the Roomba I6 compares with the Roomba i7.


In the case of the Roomba I6, we use the same battery for the I7.

This is a lithium-ion 1800mAh battery that lasts for 75 minutes at a time on average. In terms of the power system, both Roomba 6150 and the 6550 come with the capability to recharge and resume.

The battery’s lifespan is about 18 months as an average.


The Roomba i7 has a lithium-ion battery that has 1800mAh of capacity.

The battery has a 75-minute runtime in the event. The battery is brand new, but as time passes, the runtime decreases until it is a year old or two when you’ll require replacement.

The I7 series is an advanced robot vacuum that recharges itself and restarts cleaning automatically.

7. Navigation and Mapping

Robot vacuums have sophisticated systems that assist the robot vacuum in locating and mapping the floor space. Here, you will find out what the Roomba I6 is compared with the i7.


iRobot Roomba i6+ 7

In the case of the Roomba i6, there’s nothing to distinguish between them. Both models share the identical iAdapt 3.0 VSLAM Navigation, which means it comes with sensors and an image camera to help with localization.

It is a good choice in high-traffic areas since it rarely gets stuck or hit by obstructions.

Talking about floor mapping, Roombas are the best. Roombas utilizes an advanced floor-mapping system that cleans with a systematic pattern, ensuring all-level cleaning.

Another thing worth considering is the Imprint Smart Mapping system (ISMS) that provides the robot with the capability to recognize all rooms within your home.

With the technology available, homeowners can instruct the Roomba 6150 or even 6550 on how to vacuum certain rooms. Additionally, there’s a digital boundary marking known as “Keep Out Zones.”

Roomba I7 3

The iRobot Roomba i7 has a brand new iAdapt 3.0 mapping and navigation system. It is a VSLAM (Visual Simultaneous Localization & Mapping) built on a mathematical algorithm.

As the name implies, the technology uses sensors and an in-real-time camera to localize. This results in more precise as well as precise navigation.

It’s difficult for the i7 series not to get stuck or get into obstacles, even in busy rooms. In terms of floors, this robot can identify the exact layout of your home and can even save maps.

The robot can clean in a planned manner, ensuring the entire floor is cleaned. What’s more?

iAdapt 3.0 incorporates Imprint Smart Mapping technology that allows the robot to control the layout of your home.

The technology allows users to select the rooms they want to have Roomba tidy. It also provides a digital boundary feature known as “Keep Out Zones.”

8. Smart Features & Convenience

Modern robotic vacuums are homesmart and have various features for convenience. In this article, we’ll find out if the two Roombas come with the same intelligent features as well as the same convenience.


Users of the app can plan cleaning sessions, view the area the robot has been cleaning, customize the cleaning process, etc.

In addition to the operation of smartphones via apps in addition to smartphone app operation, Roomba model i6 models also work with voice assistants, including Google Assistant and Amazon Alexa.

It’s also worth noting that the Roomba I6 series of robot vacuums can sync and work with the Braava M6 robotic mop.


Roomba I7 4

All features and functions accessible for the i6 are included in the series of i7. In addition to app functionality, users can operate Roombas with voice control. Roombas use voice assistants that talk to Alexa or Assistant.

Similar to the i6, the I7 model can also be used with the Braava M6 to perform simultaneous mopping and vacuuming.

What’s the Best Choice?


This concludes this Roomba I6 comparison vs. the i7 comparison review. As you’ve seen, both models are very similar, except for some minor differences in accessories and the availability included.

The most effective choice is the Roomba I6 and Roomba i6+, which are Amazon-exclusive models with affordable prices.

In addition to the price of these vacuums, they include more features and functions, ensuring you get the most value for the money. However, they are not the only ones. The Roomba i7 is still an excellent Roomba.
