Introduction

Roomba i2 vs. i7 – which is the best bang for the buck. If you are looking for the best Roomba to buy and you are torn between the i2 and i7, this is the right place. Check out how they stack up against each other, the similarities, differences, and ultimately, the best model.

Roomba i2 is a new robot vacuum from iRobot. It was released during Amazon Prime Day 2022, when it attracted a fantastic 40% discount. On the other hand, the Roomba i7 has been around, having been released during Black Friday 2018.

The two models are in the I series, meaning they share quite a lot. The Roomba i2 and i7 are quite similar in that they are both round-shaped and have a low-profile design. They use a 3-stage cleaning system, have the same filtration, and can handle bare floors, low pile carpets, and pet hair. They are also self-emptying robot vacuums and sync with the Braava M6 robot mop. However, there are some profound differences that should inform your purchase decision. Roomba i7 comes with a much-improved navigation system with a real-time camera. It also features a smart floor mapping system that creates hyper-accurate maps of your house. Also worth mentioning are the digital boundaries of the i7 and targeted cleaning, features the i2 lacks.

Roomba i2 vs. i7 Face-to-Face Comparison Review

In this main segment of this Roomba i2 vs. i7 comparison review, find out how the two models compare. To help you make the right decision, we have compared how they square out based on the important factors considered when buying robot vacuums. So, without further ado, let's get into it.
Design and Dimensions
round-shaped

Roomba i2 is a round-shaped robot vacuum with a low-profile design. The essence of the low-profile design is to allow it to go under low-profile furniture where much of the dirt settles. It can also pass in between most tight spaces unrestricted.

Regarding the dimensions and weight, this robot vacuum is 13.4 x 13.5 x 3.6 inches and weighs 7lbs. As for the appearance and aesthetics, there is the iRobot logo at the top interface, together with 3 buttons while the color is gray.

round-shaped

Roomba i7 is also a round-shaped robot vacuum cleaner and comes in a low-profile design, too, so it can reach under low-profile furniture and other low-clearance house fittings. It also passes in between tight spaces, for example, chair legs. The dimensions are 13.34 x 13.26 x 3.63 inches, while the weight is 7.45lbs.

Regarding the aesthetics and appearance, the Roomba 692 has been finished in black and has 3 buttons plus the iRobot logo at the top.

Roomba i2 and 692 are sleek round-shaped vacuums that come in a low-profile design. The differences are negligible, so it's a draw as far as design and dimensions are concerned.

Cleaning Orientation
vacuum-only

The Roomba i2 is a robotic cleaner with vacuuming function only. It uses a 3-stage cleaning system to get the job done. The i2 is suitable for all hard floors, including tile, linoleum, laminate, vinyl, hardwood, and marble.

The i2 can also handle low pile carpets, but when it comes to medium pile and high pile carpets, it gets overwhelmed, as we will see in the cleaning test results.

Besides bare floors and carpets, you can rely on the i2 to handle pet messes such as pet hair and kitty litter.

vacuum-only

Roomba i7 is similar to the i2 in that it also deploys a 3-stage cleaning system where dirt is first agitated, then lifted before being sucked into the bin, in the third stage.

When it comes to specialization, it is best for bare floors such as hardwood, tile, ceramic, marble, laminate; you name it. But just like the i2, it is only suited for low pile carpets, but on medium pile and thick carpets, it’s not potent enough to guarantee a deep clean.

But fortunately, it can satisfactorily handle pet messes, including pet hair and kitty litter.

In this second round of this Roomba i2 vs. i7 comparison review, there is no winner as both Roombas have the same specs. They can both handle bare floors and pet messes. Also, both can handle low pile carpets, but get overwhelmed on medium and high pile carpets.

Suction Power
850-950pa

Despite being one of the latest Roombas, the i2 comes with a 2nd Gen motor, the same one included in models released as early as 2018.

This is a single-speed motor that puts up an average of 850-950pa. The i2 delivers 10× the lifting power of the 600 series models.

850-950pa
Roomba-i7-cleaning

The Roomba i7 also comes with a 2nd Gen motor which is such a big fail considering how much you will cough to buy it.

It delivers an average of 850-950pa and is also a single-speed robot vacuum so you can’t adjust suction. It also offers 10× the lifting power of the 600 series Roombas.

As far as suction goes, it's hard to call a winner as both models put up the same suction despite retailing at different prices. When price is factored in, the i2 is the winner as it's cheaper and has the same raw power as the much more expensive Roomba i7.

Mopping Performance
no mopping

Roomba i2 does not have a mopping function; it only sweeps and vacuums.

However, it is compatible with the Braava M6, courtesy of Imprint Link Technology. It syncs the two so that they team up to vacuum and mop.

no mopping

Roomba i7 is also a vacuum-only cleaner with sweeping and vacuuming functions only.

It is also one of the Roombas engineered with Imprint Link Technology so it can team up with the Braava M6.

There is no winner here. The i2 and i7 only offer sweeping and vacuum and both can sync with the Braava M6 robot mop.

Navigation
iAdapt 1.0

The Roomba i2 might be a new model but remains an entry-level model in terms of navigation. It still uses iAdapt 1.0, a Simultaneous Localization and Mapping (SLAM) system, to find its way around your house. There are obstacle detection sensors and a retractable bumper that absorbs impact when the robot hits obstacles inadvertently.

The i2 will navigate seamlessly in rooms with low to average traffic but in rooms with high-traffic, expect it to get stuck or hit obstacles here and there. But it performs much better than other Roombas with iAdapt 1.0 courtesy of Reactive Sensor Technology, which detects common household obstacles with much precision.

Besides, there are cliff sensors that prevent the robot from toppling over the stairs, and Dirt Detect, which uses optical and acoustic sensors to locate spots with heavy dirt concentration.

iAdapt 3.0

The Roomba i7, on the other hand, comes with iAdapt 3.0, the latest navigation technology from the American brand. It is a navigation system based on Visual Simultaneous Localization and Mapping, so it has a real-time camera.

The camera and obstacle detection sensors ensure that the robot navigates accurately without getting stuck or hitting objects, even in high-traffic rooms. This is one aspect that makes the i7 the best Roomba for large apartments and high-traffic rooms.

In addition to the camera and obstacle detection sensors, advanced cliff detection sensors prevent accidents when the robot is almost toppling on the stairs. The i7 also comes with Dirt Detect, which leverages optical and acoustic sensors to locate areas with concentrated dirt.

As far as navigation is concerned, the new Roomba i2 is no match for the i7 despite having Reactive Sensor Technology. The Roomba i7'S VSLAM navigation system sees just like your eyes do. It maneuvers and navigates with great precision, so you won't have to worry about the robot hitting obstacles or getting stuck as frequently as the i2 does.

Mapping
no mapping

The Roomba i2 may be a new robot vacuum, but it is not up to the mark when it comes to floor mapping.

For the record, the Roomba i2 doesn’t have smart mapping; it can’t store maps and doesn’t have extras such as Keep Out Zones and Cleaning Zones.

But then, its performance is a step ahead of the competition as it cleans in a systematic pattern for entire level coverage. In a room with less traffic, expect at least 95% coverage, while in rooms with high traffic, it cleans 90% of the floor area that needs cleaning.

Unfortunately, when it comes to boundary marking, you don’t have an option except to use Virtual Walls, which can be hectic to set up, and the nodes have to be purchased separately.

Imprint Smart Mapping

Roomba i7, on the other hand, comes with an intelligent floor mapping system dubbed Imprint Smart Mapping. The Roomba i7 smart map system allows it to create hyper-accurate maps of your house.

Then, it calculates the most efficient pattern to clean every corner of your house without skipping any spot. In a room with average traffic, expect 99% coverage, while in high traffic rooms, its coverage score is 96%.

One great thing about the i7 is that it’s one of the best robot vacuums for multi-storey houses. The Roomba i7 can save up to 10 maps.

Another great feature is the digital barriers dubbed Keep Out Zones. There’s also Cleaning Zones and other features for targeted cleaning.

The Roomba i2 is a great model as far as mapping goes considering it cleans in neat rows. However, the i7 wins this round courtesy of its smart mapping feature that enables the Roomba to create hyper-accurate maps of your house and save up to 10 maps. Besides, it comes with the floor planner on the app that gives you more control of your robot with features such as Keep Out Zones and Cleaning Zones.

Filtration System
AeroForce

Roombas don’t just vacuum; they also filter out the bad elements from the atmosphere, for example, allergens and particulates that cause bad odor. The robot uses AeroForce high-efficiency filters that capture 99% of allergens.

For the record, it captures elements as small as 0.6 microns. They are not true-HEPA filters as they don’t capture down to 0.3 microns, but still, they get the job done.

AeroForce

Roomba i7 is not different as it also has a filtration system that ensures your home’s atmosphere is free from allergens and bad odor.

Here again, iRobot opted for AeroForce high-efficiency filters that capture 99% of allergens and filter down to 0.6 microns.

Here, there is no winner as both models come with filtration systems with high-efficiency filters. They are not as effective as true-HEPA but still do a great job keeping allergens and bad odor at bay.

Brush System
two brushes

The Roomba i2 relies on a primary brushroll to agitate and lift dirt. This brush is dubbed the AeroForce Dual Multisurface Brush with Anti Tangle Technology.

The main brush, as the name suggests, consists of one brush for agitating dirt and another that lifts dirt from the surface, ready for suctioning.

One thing about this brush is the anti-tangle technology that prevents the robot’s brushes from getting jammed by long human and pet hair like in the earlier models, for example, the Roomba 690, 692, and 694.

Alongside the main brush is the sweeping side brush that spins while sweeping dirt from the wall edges and deep corners where the primary brush can’t reach.

Roomba i7+ Brush system

Roomba i7 also comes with two brush systems. First, there is an AeroForce Dual Multisurface Brush with Anti Tangle Technology, the same one that the i2 uses.

The first brush agitates dirt and debris while the second brush lifts the dirt from the floor to the suctioning area.

The i7 is one of the best Roombas for pet hair, just like the i2, courtesy of an anti-tangle mechanism that prevents the brush from tangling when picking up long hairs.

The main brush is complemented by a spinning side brush that sweeps dirt for hard-to-reach spots such as deep corners and edges.

There is no winner in this round as both Roombas come with highly specialized Dual Multi-Surface Brushes with Anti Tangle Technology. They effectively agitate dirt and debris and pick up long hairs without getting tangled as frequently as Roombas without anti-tangle mechanisms.

Bin System
0.5L

The Roomba i2 comes with a large 0.5L bin, enough to hold a day or two’s dirt in a busy household. However, it should be emptied daily to prevent the buildup of odor.

There is a full bin indicator that alerts you when it’s time to empty the bin. One great thing about the i2 is its compatibility with the iRobot Clean Base Automatic Self Emptying unit. With this addon accessory, you can forget emptying the bin now and then for a whole month.

Please note that the Roomba i2 doesn’t come with the Clean Base unit, but you can purchase it separately.

0.5L

The Roomba i7 also features a 0.5L onboard bin with a full bin indicator that notifies homeowners when the bin is full. Just like the newer models, the i7 supports automatic self-emptying for hands-free cleaning.

It’s actually the model that debuted iRobot’s innovative Clean Base Automatic Self Emptying. But here’s the catch, the Roomba i7 (7150) doesn’t come with the Clean Base unit, so you have to spend more on this accessory if you don’t want to empty the onboard bin frequently.

But there is a variant called Roomba i7+ (7550) that comes with the Clean Base unit, but of course, at a higher cost.

Here, it's hard to call a winner as both the i2 and i7 have the same bin features, are compatible with Roomba’s Automatic Self-Emptying Technology, and none comes with the Clean Base Unit. But there is a bundle that includes the i2 and the Clean Base unit and a variant of the i7 that comes with the Clean Base unit.

Battery and Runtime
1800 mAh

The new Roomba i2 maintains the same 1800 mAh lithium-ion battery that most Roombas tag along with. It can offer an average of 75 minutes, enough to handle an average-sized apartment.

When it comes to power management, this Roomba will dock to recharge when the power goes down. After the 2-3 hours recharge time, it will leave the docking station to complete the cleaning session from where it left.

1800 mAh

The Roomba i7 is also equipped with a lithium-ion battery with a 1800mAh capacity, enough to power the cleaner for 75 minutes.

As for power management, the i7 can recharge and resume cleaning automatically, just like the i2, so at no time will you step into your house and find it halfway cleaned. The recharge time is around 2-3 hours.

Here again, there is no winner as both robot vacuums have the same battery specifications. The runtime, power management options, and recharge time are all the same.

Automation and Smart Features
2.4GHz WiFi

Roomba i2 has plenty of automation and smart features. To start, this robot vacuum is compatible with 2.4GHz WiFi that facilitates remote operation via the mobile app or voice assistants. The app allows you to set cleaning schedules and access many other controls.

At the core of this new Roomba is iRobot OS, the company’s proprietary operating system that has been rolled out in several top-of-the-range models. It is also compatible with Alexa and Google Assistant.

2.4GHz WiFi

Roomba i7 also supports 2.4GHz WiFi for remote app operation and voice assistant compatibility.

The i7 can be linked with the iRobot Home app and voice assistants such as Alexa and Google Assistant.

It’s also one of the Roombas with iRobot OS that opens up a whole new world of possibilities courtesy of intelligent suggestions.

No winner here again, as both vacuums share the same automation and smart features.

Warranty and Aftersales
1-year

Roomba i2 comes with a 1-year warranty in case your Roomba develops problems. But make sure to abide by the warranty’s terms. As for support, iRobot has plenty of resources. Last, even though this is a new Roomba, there are plenty of affordable supplies such as filters, brushes, and replacement parts.

1-year

The i7 also comes with a 1-year warranty. Support is also available in the form of guides and videos. Being an older model, you can find a variety of supplies and replacements from both iRobot and other brands.

This ends in a draw as both models are from the same brand. A brand with a trusted warranty and excellent aftersales.

Maintenance

Brush
replaced after 6-8 months

The Roomba i2’s main brushroll may have anti-tangle technology, but it’s not invincible. Regularly inspect the brushroll to ensure there are no hair tangles and stuck on dirt that could impede its performance.

Also, check whether the side brush is spinning freely and remove any tangles. The primary and secondary brush should be replaced after 6-8 months.

replaced after 6-8 months

Roomba i7 is not different in terms of maintenance. Its brush should also be inspected regularly to ensure there are no tangles or stuck-on dirt that could jam the brush.

The side brush should also be spinning freely. The main brush and side brush should be replaced after 6-8 months.

Filter
replaced after 2-3 months

Roomba i2 comes with AeroForce high-efficiency filters that require maintenance at least twice a month or weekly if you deal with lots of dust and fine particles.

Pop out the filter, tap it in the bin, rinse using cold water and let it dry before putting it back. Buy a replacement after 2-3 months.

replaced after 2-3 months

Roomba i7 also has AeroForce high-efficiency filters that require frequent maintenance for optimal performance. At least twice a week, or thrice if you are in dusty areas, clean the filter.

The drill is the same; tap it in the trash can to remove excess dirt, rinse using cold water, let it dry, and put it back. Replacement is also after 2-3 months.

Bin
once the bin is full

The Roomba i2 doesn’t come with iRobot’s automatic self-emptying system, so you have to empty the bin manually. Once the bin is full, pop it out, and empty the dirt. Wash if necessary.

For the record, the i2 works with the Roomba Clean Base unit. If you have one, the maintenance requirements are lower as the robot empties itself automatically. Your job will just be changing the disposable bags after a month or so.

once the bin is full

Roomba i7 also doesn’t come with the Clean Base unit, so you have to empty the bin manually. Eject the bin, empty the contents, and wash if necessary before returning it.

For the record, the i7 works with the Clean Base unit, so if you have the Clean Base, you won’t have to mind about manually emptying the bin. Your only job will be disposing of the full bags and replacing a new one, at least monthly.

Frequently Asked Questions

Can the Roomba i2 empty itself?

No. The Roomba i2 can’t empty itself. It doesn’t come with the iRobot Clean Base unit. Instead, it comes with the standard docking station with the recharge function only. However, the robot is compatible with iRobot’s automatic emptying technology. With the Clean Base unit, bought separately, the i2 will empty itself.

FAQ

Why is my Roomba not moving?

There are several reasons that could make a Roomba not move. The first thing to check is where there is an obstacle preventing the Roomba’s wheels from climbing. Second, check whether the wheels have any tangles.

My Roomba keeps hitting obstacles

If you have a high-traffic room and an entry-level Roomba with old navigation technology, it’s common to see the Roomba hit obstacles or find it stuck. However, in a room with average traffic, obstructed sensors could be the cause. Locate the sensors and use a damp cloth to wipe them carefully.

Can Roombas mop?

No. Unlike Roborock, ECOVACS Deebot, and iLIFE, which have robot vacuums that can mop, there is no Roomba mop. Instead, there’s the Braava which can sync with select Roombas to vacuum and mop in sync.

Wrapping Up

That’s the end of this Roomba i2 vs. i7 comparison review. As you have seen, the two share quite a lot now that they are from the same series, Roomba I series.

They both have a low-profile design and use a 3-stage cleaning system. The i2 and i7 also have the same runtime and can recharge and resume cleaning. Besides, they are self-emptying robots though they don’t come with the Clean Base Unit. What’s more? Roomba i2 and i7 work with the Braava M6 in sync courtesy of Imprint Link Technology.

However, the Roomba i7 is superior as it comes with an advanced navigation system dubbed iAdapt 3.0, which combines sensors and a real-time camera for better navigation. It also boasts Imprint Smart Mapping, which creates and saves up to 10 hyper-accurate maps for efficient and entire-level cleaning. Plus, it brings on board other extras such as Keep Out Zones, which is more convenient than Virtual Walls, and Cleaning Zones for customized cleaning.
