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.

roomba i4 vs i7 differences

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:

roomba i4 vs i7 similarities

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.

Important! The iRobot Clean Base is only included with the “+” series. You will therefore have to purchase it separately. If you do not purchase the clean base, then you’ll have to empty the garbage bag every two months.

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.

roomba i4 vs i7 rubber brushes

  • 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.

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:

roomba i4 vs i7 features

1. Effective Cleaning System

Let’s see how the i4 cleans:

Roomba i4

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:

  • Hardwood;
  • Vinyl flooring;
  • Tiles.

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.

  • Impressive Performance in High-Traffic Areas: I tested this robot vacuum in a room with a larger and high-traffic Despite the challenges posed by a more demanding environment, the Roomba i4 delivered impressive cleaning results.
  • 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.

3. Mapping

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.
Note: To be clear, the Roomba i4 cannot build or save maps.
roomba i4 vs i7 mapping

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.

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.

braava 6

Winner: They are tied, because both haven’t mopping features. But at the same time are compatible with Braava M6.

5. Filtration

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:

roomba i4 vs i7 suction power

  • The charging time is similarly three hours.

Winner: The i4 takes the big win by having an improved battery life and more cleaning runtime.

9. Dustbin Features

The Roomba i4 has an integrated 0.5L bin with a full bin indicator.

  • When the trash can is full, it has to be cleaned.
  • As this model is one of the earlier launches, it does not feature an automatic feature that empties the dust from the robot. This does not come with the iRobot Clean Base unit.
  • If you want to use the automatic functionality then you need to buy the Clean Base unit which is sold individually.
  • The unit may store dirt for up to 30 days.

The Roomba i7 also has an inside bin, although a smaller 0.3L bin, however, the full bin indication is still there.

roomba i7+

  • This container must be manually emptied, ideally after each cleaning area.
  • If you are looking for the same model that empties itself automatically, then I would suggest going for the Roomba i7+. This particular model has a disposable bag that can hold a month’s worth of dirt.

Winner: The i4 stands tall here with a greater discharge capacity for dirt.
