Roomba i3 vs. i7 Buying Advice
The Story Behind iRobot
iRobot has been around since 1990 and was founded by Massachusetts Institute of Technology roboticists.

The introduction of the brand’s home robot has changed the way homeowners clean, giving you more time to focus on what really matters. Their range of cleaning products include the Roomba robot vacuums, Braava robot mops, and iRobot handheld vacuums. Over 30 million home robots have been sold since iRobot’s first introduction of cleaning products.

Features
With both robot vacuums sharing very similar advantages, let’s take a more in-depth look at their features. This way, you can decide if you would benefit from the advanced features offered by the Roomba i7 robot vacuum.
Power
Both the Roomba i3 and i7 offer a powerful performance with up to 10 times more suction that sucks up dirt, debris, and pet hair with little effort. Both can handle stubborn dirt build-up by having strong lifting up suction as well as premium 3-stage cleaning with dual multi-surface rubber brushes.
No matter where the dirt is lurking, these robot vacuums will have it pulled up and taken away effortlessly. Both machines are also able to detect where there’s more dirt, giving the area a more thorough clean.
Navigation Technology
Using smart navigation aided by floor tracking sensors, the Roomba i3 can clean your floors in neat rows whether it’s a hardwood floor cover or carpeting. The Roomba i7 can do exactly the same with its vSLAM technology. Also known as visual simultaneous localization and mapping, the vacuum can map your entire home while keeping out of zones it shouldn’t go to.
The “Keep Out Zones” feature of Roomba i7 is an attractive feature if you want to protect valuable antique furniture in your home or stop the vacuum from bumping into your pet’s water bowl.
Customized Cleaning Schedules
The Roomba i7 and i3 will suggest personalized schedules based on your own cleaning habits. This means you can get on with what you have to do while leaving your robot vacuum to plan and execute its cleaning schedule.
These appliances are also programmed to suggest when to add extra cleaning during seasons with high pollen counts or when your pet starts to shed heavily.
Voice Commands
The joy of using either the Roomba i3 or i7 is that you can send commands using the iRobot Home app, Alexa or Google Assistant. When you instruct your robot vacuum to “clean the kitchen” it will do exactly that for you, meaning you can relax knowing the job is being done. Spills can be sorted out immediately on your command too.
By issuing voice commands, you can continue doing what you’re doing without having to worry about cleaning up the mess.
Recharge and Resume
A nifty feature of both the i3 and i7 Roomba vacuums is the ability of the machine to know when its battery is running down. It will recharge according to the amount of time still needed to finish the cleaning job, and it will pick up from where it left without cleaning the same areas all over again.
Without skipping a beat, the vacuum will recharge and resume, giving you peace of mind that the cleaning job is done properly and efficiently every time.
Pet Friendly Brushrolls
Both the Roomba i3 and i7 models include anti-tangle brushrolls. This means you’re no longer wasting time detangling pet hairs from the vacuum. The dual multi-surface brushes are made with rubber and the hairs are sucked in without getting caught up in the brushrolls.
Another bonus feature of these robot vacuums is that they include highly efficient filters which traps any cat or dog allergens. This helps to keep both the floors and air clean, helping you prevent any allergic reactions to pet dander.
Top 3 Roomba Products
Review: iRobot Roomba i3
The Roomba i3 offers top features for keeping your house clean at all times. It works on multi-floor surfaces including hardwood and carpets, and its hair cleaning system is ideal for homes with pets.
It knows where to go without getting stuck, and cleans in neat rows. It’ll also sort out any stubborn dirt or debris by detecting it. It weighs in at 7.44 pounds, making it a lightweight vacuum. It’s small too, measuring in at 13.26 inches wide x 3.63 inches high x 13.34 deep.
Reviews have indicated that the vacuum may bang on certain parts of the room such as the door. It also doesn’t allow you to program the running time but it still gets the cleaning job done after recharging. Also, it may occasionally miss a single spot while cleaning but this seems to be a minor complaint.

Review: iRobot Roomba i7
Sharing most of the features of the i3 robot vacuum, the i7 is a favorite if you like to specify which rooms it must clean and where it mustn’t go. It’s also easier to maintain by simply wiping down its sturdy plastic body after it’s done a cleaning job.
You can link it with the Braava jet m6 robot mop and get all your vacuuming and mopping done in one go, but this feature is also available with the i3 model. It also weighs the same as the i3 and measures the same in size.
It’s recommended to purchase the separate Clean Base Automatic Dirt Disposal bin if your home accommodates a lot of pets. This way you don’t have to waste time emptying loads of pet hair out!

Features To Consider When Buying A Roomba i3 or i7

The same applies to robot vacuums, and both the i3 and i7 Roomba have 10 times more powerful suction compared to other vacuum cleaners. This makes them extremely effective in removing both light dirt and stubborn debris, as well as pet hairs.

With iRobot’s Genius technology, you can create a personalized cleaning schedule unique to your routine and habits. This technology also factors in insights such as seasons and the shedding behavior of your pets.
When deciding between the iRobot i3 and i7 smart technology features, they both have the Genius function; however, the i7 goes one step further by including a smart mapping function for specific room cleaning and keeping the vacuum out of places it shouldn’t be in.
The winner in this category goes to the Roomba i7.
Ease of Use
When using robotics for home cleaning, you want to know it’s easy to use. User-friendly features should include being compatible with both iOS and Android devices as well as apps. You also don’t want to be fiddling with a gadget, taking up more of your time.

Both the i3 and i7 win hands down for ease of use.
Maintenance
Vacuum cleaners get dirty when vacuuming the floor, picking up dirt, debris, and pet dander. This means you also need to give them a wipe down occasionally to keep them clean. Bins or cylinders also need to be removed and emptied if you want to keep your vacuum operating optimally.
When comparing maintenance between the i3 and i7 Roomba, it should be noted that the debris bin is small, requiring regular emptying; however, if you purchase the Clean Base Automatic Disposable bin, you only need to empty it every 60 days.
The Roomba i7 is a close winner here, but only because it’s completely constructed with plastic, making it easier to wipe down.
FAQs
The Roomba i7 has a plus model called i7+. The difference between the iRobot i7 and i7+ lies in its emptying features. The i7+ comes with the automatic clean base for emptying the bin and it’s larger than the original debris bin on the i7.

Remove the filter from the bin before washing it by hand in warm water. Leave it to dry before replacing the filter and attaching the bin back to the main unit. According to the manufacturers, the bin must never be placed in the dishwasher.
Final Thoughts
When deciding between the Roomba i3 vs. i7, we found both to be highly efficient robot vacuums. Yes, the iRobot i7 has a few more advanced features, but we felt these were negligible compared to what the i3 Roomba could offer at a lower price.
