Difference 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) camera that is available only in the Roomba i7 but not in the Roomba i3. This camera gathers over 230,400 data points per second enabling the Roomba 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 Roomba i7 will remember all the obstacles and furniture and will avoid them instead of bumping into them. With the help of this camera, the Roomba i7 will make its way around all the obstacles and furniture instead of finding its way after bumping into them.

Keep-Out Zone

Another difference between the Roomba i3 and i7 is the keep-out zone feature that only the Roomba i7 offers. with the help of this keep-out zone feature, you can select a specific area on the map through the iRobot Smart App that you want your Roomba i7 to ignore while cleaning. The Roomba i7 will not go near this selected keep-out zone while cleaning your floor. This feature comes in handy if you want to keep your Roomba 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. With this feature, you can direct your Roomba i7 to clean a specific area in a specific room. Your toddler spilled the 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 your Roomba i7 will do the rest. This feature is not available in Roomba i3. 

Battery Timing

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

Build Material

Roomba i7 has a full plastic body which is easy to clean. Roomba i3, on the other hand, has a ring of fabric around its top, which sometimes becomes a hectic job to clean.

Price Difference

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

Similarities Between Roomba i3 and i7

Smart Navigation

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

Smart Mapping

Both the Roomba i3 and i7 now have smart mapping features. Although Roomba i3 didn’t have this feature initially when it was launched in 2020. But in the recently released iRobot Genius 4.0 upgrade, iRobot has introduced this smart mapping feature, among other features, in the Roomba i3 as well. 

Both the Roomba i3 and i7 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 the Roomba i3 and i7 to offer room-specific cleaning. This means, with the help of the iRobot Smart App, you can select your Roomba i3 and i7 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, Roomba i3 and i7 will suggest you to put a Keep-Out Zone in that area. 

Another cool feature of this iRobot Genius technology is that the Roomba i3 and i7 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, both the Roomba i7 and the Roomba i3 can team up with the Braava Jet M6 robot mop on hard floors. Once Roomba i7 or i3 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 of either Roomba i3 or i7. 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. Smart navigation and mapping features enable both Roomba i3 and i7 to remember which area they have cleaned and which area is still left to be cleaned. 

Anti-Tangle Rubber Bursh

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

Roomba i3 and i7 have double brush rollers that enable impressive carpet cleaning, picking up even the stubborn messes easily.

Voice Assistance

Both the Roomba i3 and i7 are compatible with voice assistants like Alexa and Google Assistant. Both these models enable you to clean your home without raising a finger. With the release of 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 Roomba i3 and i7 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 the Roomba 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 Roomba i7 is surely the better choice when compared with the Roomba i3. 

Having said that, if you have a small house and you don’t need the extra smart features that the Roomba i7 offers, the Roomba i3 is a better choice for you. You need to spend $300 more on i7 if you don’t need those extra features.

Difference Between Roomba i3 and i3+

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

Difference Between Roomba i7 and i7+

Similarly, the difference between Roomba i7 and Roomba i7+ is the self-emptying feature available in Roomba i7+ only. Just like Roomba i3+, the Roomba 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 Roomba i7+ is a bit bigger as compared to the Roomba i7. This is because of the presence of the automatic dirt disposal compartment mounted on top of the Roomba i7+. 

This literally makes cleaning a touchless chore. You just need to direct your Roomba i3+ either 

through iRobot 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.
