Robot vacuums may just be one of the best inventions ever, able to take on the arduous task of cleaning the floor without any supervision. But as smart as they are, they still need the help of humans to clean them out once they’re full. Roomba, however, now has self-emptying models that are able to clean up after themselves, saving us from any sort of manual labor. If that sounds like your kind of robot vacuum, two models you should look into are the Roomba i3+ and i7+, both of which are able to give users a fully automated experience. To help you decide between the two, here’s an in-depth comparison, taking their design, cleaning, navigation, battery, and capacity into consideration.

The Roomba i3+ and i7+ are very similar in design.
The most obvious similarity between the Roomba i3+ and the i7+ would have to be their shape. They both sport a round design instead of the D-shaped silhouette that’s seen on some of the other Roomba models like the s9+. Also, their Home, Clean, and Spot buttons are found in the same places on the top panel, a pattern that should be familiar to existing Roomba users. Both the i3+ and the i7+ are equipped with a Clean Base as well which makes it possible for these models to clean up after themselves. Basically, there’s a vent on the Clean Base that suctions out the contents of the dustbin, saving you from the hassle of having to empty it out.
Flip the i3+ and the i7+ over and you’ll see that they look pretty much the same underneath too. Both are equipped with Roomba’s proprietary multi-surface rubber brushes which are great for cleaning up pet hair. The strands won’t get tangled up in them like how they do with regular brush bristles. These special brush rollers are also able to adjust to the thickness of your carpets as well as clean just about any type of surface including tiles and hardwood floors. To boot, the i3+ and the i7+ also have an edge-sweeping brush that’s able to get into the nooks and crannies of your home.
For those who suffer from allergies, you’ll be happy to know that these two models boast of high-efficiency filters that are able to trap 99% of dirt, dust, pet hair, pollen, mold, and allergens as they clean your house.
The i7+ is more advanced when it comes to navigation but the i3+ is just as capable when it comes to cleaning.
Navigation is where the differences between the i3+ and the i7+ become more obvious. On the i7+, you get to enjoy something called Imprint Smart Mapping, a feature that’s missing on the i3+. With Imprint Smart Mapping, the i7+ is able to remember the map of your home for all future uses, plus it allows you to edit and customize the map of your house. You can, for example, add keep out zones, send the i7+ to specific rooms, as well as assign targeted clean areas. In order to build an entire Smart Map of your house, the i7+ will need to complete two runs. After that, the map is free for you to tailor to your liking.
Imprint Smart Mapping aside, you can expect both the i3+ and the i7+ to navigate their way around your house with ease. With their navigation tracking sensors, they’re able to clean efficiently, moving in straight lines instead of just wandering around aimlessly. They’re equipped with Reactive Sensor Technology as well so that they’re not bumping into or getting stuck in between your furniture and other objects.
As for cleaning capabilities, the i3+ and the i7+ are on par with each other. They’re both designed with Roomba’s patented 3-Stage Cleaning System as well as 10 times the suction power of the Roomba 600 series, meaning dirt, dust, pet hair, and large debris really have no chance of sticking around in your house. Not just that but they have Roomba’s proprietary Dirt Detect Technology as well which allows them to find the dirtiest spots in your home and spend more time cleaning them up.
Battery and Capacity
Both the i3+ and the i7+ have the Recharge and Resume feature and don’t need to be emptied out for 60 days.
Both the i3+ and the i7+ run on lithium ion batteries which make them pretty efficient to use and charge. The best thing about these two models though would have to be their Recharge and Resume feature which steps in when they’re low on juice. Basically, they’ll recharge automatically for around one and a half to two hours and will then pick up from where they left off. This feature is great because you don’t have to keep a constant eye on the i3+ or the i7+. You can count on them to take care of things on their own and get the job done. As for capacity, both models can empty themselves out for 60 days.
Get the i7+ if you want maximum control over your Roomba but purchase the i3+ if you’d rather save.
There really aren’t a lot of differences between the Roomba i3+ and the i7+ in terms of design, cleaning capabilities, and battery. They’re both able to clean up after themselves as well. The i7+ does, however, have a big advantage over the i3+ and that’s its Imprint Smart Mapping feature. If you want to be able to have full control over the way your Roomba cleans (and you don’t mind having to shell out more), it would be better to purchase the i7+ because it allows you to customize the map of your house, set certain parameters, and designate target areas. If all you want, however, is a robot vacuum that’s able to keep your house clean, the i3+ is the more cost-effective option.
Both are equipped with Roomba’s patented 3-Stage Cleaning System and they have 10 times the suction power of the Roomba 600 series as well. They also have Roomba’s proprietary Dirt Detect Technology, allowing them to find and clean up the dirtiest spots in your home.
The i7+ is more advanced in terms of navigation. With its Imprint Smart Mapping feature, the i7+ is able to remember the map of your home for all future uses, plus it allows you to edit and customize the map of your house.
If you want full control over your Roomba’s cleaning, it’s better to go with the i7+. But if you can do away with the Imprint Smart Mapping feature and would rather save, the i3+ would be the better pick.
