Roomba i4: The Pros and Cons
Let’s have a look at the benefits and drawbacks of the i4 Roomba:
- The vacuum cleaner has simple controls and an easy-to-use app.
- It is inexpensive and suited for individuals on a tight budget,
- Its extended battery life allows it to clean more places in a single cleaning session.
- It finds it tough to vacuum up hair on bare floors.

Now next I will go over the pros and cons of the Roomba i7:
- Advanced tracking detectors and camera.
- Clean base digital waste disposal mechanism in the charging port.
- Increased suction power technology force for excellent cleaning of a variety of floor kinds.
- The battery life of the robot is limited.
What Sets the Roomba i4 and the Roomba i7 Apart?
Here are some of the things which both these affordable robot vacuums have different with each other.
1. Sensor Navigation
The i7 unit cleaner will tour your house and learn the placement of various indicators such as items of furniture. Because it works with its camera for navigation, it will require some normal illumination when cleaning your house.
Whereas the Roomba i4 lacks inbuilt cameras. Instead, it navigates your home using floor tracking sensors.
2. Saving Mapping System
When you first use the i7, it may take some time to understand the structure of your home. When the process is completed, it will generate maps with specific labels that you may keep.
If you live in a smaller house and don’t use the mapping feature frequently, the i4 will do the job.
3. Keep Out Zones Functionality
With the i7 model, you can enable to select specific places in your home that you want to keep the vacuum out of. The iRobot software allows you to draw these areas.
- These are called Keep out zone.
- This is an excellent method for keeping it away from valuable products and out of narrow areas.
In contrast, the i4 model does not have this functionality. This means you’ll either have to manually block off regions of the entire house where you don’t want the Roomba to operate. Or get an iRobot Virtual Wall Barrier for labeling these locations.
What Features Do the Roomba i4 and the Roomba i7 Share?
Here are some of the features both of the models have in common:
1. Dirt Disposal System
Both of the devices, the Roomba i4 and i7 are compatible with an iRobot Clean Base Automatic Dirt Disposal. This clean base is essentially a docking station that charges your vacuum and gets rid of the dirt the unit has collected after each cleaning session.
2. Automatic Recharge Function
Automatic recharge function means:
- Whenever the batteries of the cleaners go low, they will pause that session.
- Next, they go to the respective charging stations to power their battery life.
- After the battery is entirely charged, the robot will continue its cleaning routine from where it initially left off from the previous session.
3. Rubber Brushes
These vacuums come with a dual brush system, which loosens fire.
- The two brushes work together to remove any kind of dirt, grim, and leftover from multiple surfaces such as hardwood floors, flooring, tiles, and carpet floors.
- Another brush picks up the dirt into the vacuum’s body.
- The brushes have three-sided prongs. This helps the cleaning units to be able to collect dust and debris into their suction body.
4. iRobot App Functionality
The Roomba i4 and i7 come with a great user-friendly app called “iRobot”.This enables you to access amazing functions through the app. This includes:
- Easy activation of the device.
- Making specific cleaning paths to follow.
- Setting preferred schedules for cleaning.
- Control via voice command.
5. Smart Navigation
Both the i4 and i7 are able to navigate around your home in an analytical manner. In order to thoroughly clean your floor, they work in straight, precise lines.
In contrast, earlier-generation other robot vacuums employ a “bump and turn” navigation approach and travel randomly to clean a room.
Roomba i4 vs i7: A Showdown of 11 Key Features
To assist you in making the best purchase decision possible, let’s discover the 11 major features. Read on to see which model emerges victor in most categories:
1. Effective Cleaning System
Let’s see how the i4 cleans:
The Roomba i4, like all previous Roombas, is efficient at sweeping and vacuuming tasks. In terms of specialization, it is a better choice for non-covered surfaces such as:
- Vinyl flooring;
It is also intended for mild low-pile carpet vacuuming. Because of the anti-tangle brush mechanism, the i4 is perfect for users who have a long-haired pet and face with pelts of fur all around the floor.
Now let’s see how the i7 operates:
- The i7 works great on all surfaces covered and uncovered like carpeted flooring.
- As the i7 is supported by a state-of-the-art Imprint System. The Braava M6 is required for the duo function for both mopping and sweeping the floors.

- Reactive Sensors: These advanced sensors work in harmony with the iAdapt 1.0, significantly enhancing the Roomba i4’s ability to detect and avoid impediments while it’s cleaning. This combination ensures the robot vacuum can navigate around your home safely and efficiently.
The Roomba i7, on the other hand, includes:
- iAdapt 3.0: The ground-breaking iAdapt 3.0 technology to make you cleaner smarter.
- VSLAM System: Unlike the simultaneous locating and mapping algorithm used by the Roomba i4, the i7 employs a VSLAM-based system that integrates the real-time powerful camera with that reactive fast-paced sensors.
- Object Avoidance: The robot avoided blockages more precisely and rarely became trapped as compared to the i4.
This is suitable for people with large residences and heavy-traffic rooms.
Winner: The i7 undoubtedly has a better system for navigating around obstacles which enables it to avoid certain areas and blockages. Hence, it stands victor in this category.
In terms of mapping, the Roomba i4 lacks once more.
- It misses advanced floor scanning and mapping technology, thus it cannot learn, map, or adapt to your home’s floor layout.
- Instead, it will move about randomly while cleaning. Long-term, especially in big apartments, it could leave certain areas unnoticed.
- Unfortunately, the i4 does not support digital boundaries for boundary marking.
Roomba i7, on the other hand, scans and maps your home using the ground-breaking Imprint Smart Mapping technology.
- Unlike the i4, the i7 will learn, map, and adapt to the layout of your house to ensure effective cleaning.
- The robot can build extremely precise maps of your home and save up to ten-floor layouts, making it suitable for multi-level homes.
- Even in big flats, the i7’s regular cleaning routines ensure that the whole level is cleaned.
- Finally, the i7 includes digital barriers known as Keep Out Zones.
- This function enables homeowners to draw borders directly from the app.
Winner: The i7 takes the win making it a better choice in terms of mapping. The smart imprint technology makes it a smart and more efficient device than its counterpart.
4. Mopping Performance
As previously mentioned, the Roomba i4 is a vacuum-only robot. There is no mopping feature. And, the same goes for the Roomba i7. If you want to employ the mopping feature, then purchase the Braava 6 which is compatible with both i4 and i7 to enable this functionality.
Winner: They are tied, because both haven’t mopping features. But at the same time are compatible with Braava M6.
Both the Roomba i4 ad i7 have come equipped with AeroForce high-efficiency filters.
- These collect 99% of allergens like pollen and dust mites, leaving the environment clean.
- While these filters are effective, they are not real HEPA filters and cannot filter down to 0.3 microns as can HEPA grade filters. Regardless, they do an excellent job.
Winner: When it comes to filtration, there is no clear winner. Both the Roombas have the same technology for filters using identical methods for cleanup.
6. Suction Power
Here is a rundown of important highlights regarding suction power:
- The Roomba i4 is ideal for medium suction and utilizes the same technology as the Roomba 800 series and Roomba 960.
- The Roomba i7 has the same specifications in terms of suction power as it uses the identical 2nd generation motor.
- Both units deliver approximately 850 – 900pa.
Winner: Both of them stand the same in this category as they employ the 2nd gen motor for dirt pickup.
7. Types of Brushes
The two-brush system is present in both vacuum cleaners.
- Featuring anti-tangle technology these products have an AeroForce dual multi-surface brush system. The first brush removes and stirs the dirt from the floor. The second brush helps in lifting up the dirt from the surface into the suction pipes.
- I appreciate the fact that it does not tangle even while managing long dog hairs.
- It is excellent at collecting all types of material, from microscopic particles to huge residues such as sand granules and sawdust.
- For sweeping, a side brush is also included for cleaning the edges of walls and in-depth corners.
