Differences Between Roomba i3 and i7

VSLAM Camera

One major difference between the Roomba i3 and i7 is the built-in vSLAM (Visual Simultaneous Localization and Mapping)[1] camera that is available only in the i7 but not in the i3. This camera gathers over 230,400 data points per second enabling the i7 to create multiple interactive maps of your house. This smart interactive mapping enables a lot of advanced features like Keep-Out Zone, and Clean Zone which are discussed below.

This vSLAM camera also guides the Roomba i7 through all the obstacles in the area. After making some initial runs in your house, the i7 will remember all the obstacles and furniture and will avoid them instead of bumping into them. 

Keep-Out Zone

Roomba i7 offers keep-out zones that only the i3 robot lacks. This feature allows you to select a specific area on the map through the iRobot Smart App that you want your vacuum to ignore while cleaning. This feature comes in handy if you want to keep your robot vac from going near places where there is clutter like cables and cords or near pet food pots etc.

Clean Zone

With the slogan of “Goodbye cleaning. Hello clean.” iRobot launched the “Clean Zone” feature in the Roomba i7. You can direct i7 to clean a specific area in a specific room. Your toddler spilled cereal on the carpet in the living area? No worries. Just yell at Alexa or Google voice assistant “tell Roomba to clean the carpet in the living area” and the voice assistant and the i7 will do the rest. This feature is not available in the  i3 model. 

Battery Timing

The Roomba i7 has a more powerful battery as compared to the i3. It offers up to 90 minutes of runtime and 180 minutes of charging time. Roomba i3, on the other hand, has a runtime of up to 75 minutes and a charging time of 90 minutes.

Build Material

Roomba i7 has a full plastic body which is easy to clean. The i3 has a ring of fabric around its top, which sometimes becomes a hectic job to clean because the fabric attracts more dust.

Price Difference

Since there are so many advanced features that are only available in the Roomba i7 and not in the i3, one can surely expect that there will be a price difference between them as well. 

Similarities Between Roomba i3 and i7

Smart Navigation

Both robot vacuums clean your house in neat and straight lines. The built-in sensors enable smart navigation for both the i3 and i7. These sensors let them clean intelligently in tidy lines instead of cleaning in random circles. 

Smart Mapping

Both models now have smart mapping features. Although the i3 didn’t have this feature initially when it was launched in 2020, in the recently released iRobot Genius 4.0 upgrade[2], iRobot has introduced this smart mapping feature, among other features, in the Roomba i3 as well. Both models will create interactive maps of your floors. These interactive maps enable some more advanced features. You can label these maps according to your needs, for example, Dining Room, Kitchen, or Living Room. This labeling feature enables both models to offer room-specific cleaning. This means, with the help of the iRobot Smart App, you can select them to clean a specific room only.

Cleaning Suggestions

With the help of the iRobot Genius 4.0 update, both the Roomba i3 and i7 keep learning from your cleaning habits and offer cleaning suggestions. For example, if you have selected a certain area as a Keep-Out Zone, the next time you forget, both models will suggest you put a Keep-Out Zone in that area. 

Another cool feature of this iRobot Genius technology is that the robot vacuum will also give you cleaning suggestions according to the seasons. For example, during pollen seasons or during pet shedding seasons, it will suggest extra cleaning.

Imprint Link Technology

With the help of Imprint Link Technology[3], both the Roomba i7 and the i3 can team up with the Braava Jet M6 robot mop on hard floors. Once the robot vac has completed cleaning the whole house or the designated area, it will send a signal to the Braava Jet M6 to start mopping the designated area. This auto clean and mop combination is a blessing every hard floor owner dreams of. 

Recharge and Resume

With the recharge and resume feature, available in both models, you don’t have to worry about the battery timing. Because, if any one of them is out of battery charge during a cleaning session, it will return to its charging dock, start charging, and once it has enough power, it will start cleaning right from where it left off. Smart navigation and mapping features enable both robot vacs to remember which area they have cleaned and which area is still left to be cleaned. 

Anti-Tangle Rubber Brush

One feature that makes Roomba models stand out against other robot vacuum brands is the anti-tangle brush roller. These rollers are different from the traditional bristle brush rollers that get tangled easily with hair and fluff. 

Both i3 and i7 have double, anti-tangle rubber extractors that enable impressive cleaning, picking up debris even from deep down the carpets and rugs easily.

Voice Assistance

Both models are compatible with voice assistants like Alexa and Google Assistant. This enables you to clean your home without raising a finger. With the release of the iRobot Genius 4.0 update, the Roomba i3 is now compatible with Apple’s Siri as well. 

Dirt Detect Technology

Both the Roomba i3 and i7 have the iRobot patent Dirt Detect Technology. This enables both models to focus on the area where there is more dirt and clean it thoroughly. Both models have a dirt sensor installed underneath them. This sensor, when comes in contact with dirt and debris, activates the focus cleaning mode, and the robot vac will run over the dirty area over and again until the last grain of dust is not picked up. 

Which one is better, Roomba i3 or i7

After comparing both i3 and i7 and considering all the differences and similarities, we can easily call Roomba i7 the winner. With some extra smart features like Keep-out zones and Clean zones, a vSLAM camera, and better battery timing, the i7 is surely the better choice when compared with the i3. 

Having said that, if you have a small house and you don’t need the extra smart features that the i7 offers, the Roomba i3 is a better choice for you. You can save some money if you don’t need those extra features. 

Difference Between Roomba i3 and i3+

The only difference between the Roomba i3 and i3+ is the automatic dirt disposal feature indicated by the ‘+’ sign. The i3+ has a self-emptying feature that the i3 doesn’t have. The HomeBase of the i3+ model is bigger as compared to the i3 because the self-emptying compartment is mounted on top of the HomeBase. The Roomba i3+ can empty itself in the HomeBase for up to 60 days.

Difference Between Roomba i7 and i7+

Similarly, the difference between the Roomba i7 and i7+ is the self-emptying feature available in the i7+ only. Just like the i3+, the i7+ will also empty itself into the HomeBase for up to 60 days and keeps you tension-free from cleaning jobs. 

The HomeBase of the i7+ is a bit bigger just like the i3+ because of the presence of the self-empty compartment. 

This literally makes cleaning a touchless chore. You just need to direct your Roomba i3+ or i7+ either through Smart App or just through your voice, it will start cleaning your house. Once it cleans all of the house, it comes back to the 

HomeBase and empties itself automatically into the HomeBase for up to 60 days.
