Both the Roomba i3 and i4 robot vacuums are well-known wonders that can help you keep your home clean and tidy whether you need a strong, powerful clean or just need to pick up a few crumbs that have been left behind after dinner.
But which one is worth your hard-earned money? We’re here to give you the details on both robot vacuums, so you don’t have to make the decision alone.
iRobot Roomba i3 Robot Vacuum
Let’s begin with the iRobot Roomba i3 Robot Vacuum, which weighs just 11.4lbs and runs off of its incredible long-lasting lithium ion battery to provide you with the longevity and power for a great clean every time.
With 10X the powerlifting suction of other Roombas and a 3-stage, premium cleaning system, even stubborn dirt left behind in high traffic areas and dirt spots left behind by pets will be sucked clean immediately, leaving you with sparkling floors.
In fact, its unique multi-surface rubber brushes are quick to wipe away dirt and don’t get tangled with your pet’s hair, making them the perfect addition for a quick clean.
That’s not all the i3 has to offer, though. With Imprint Link Tech and its accompanying Braava jet m6 robot mop, your floors won’t only be “swept to perfection,” but they’ll be mopped to perfection too, leaving you to spend time on more important matters.
The Roomba i3 is equipped with an ultra-smart navigation system that maps your home and cleans in neat rows. All thanks to its tracking sensors that know the difference between your hard floors and carpets.
With extra Reactive Sensor Tech, the i3 knows where it will and won’t fit, so you’ll never have to retrieve it from a tight corner or save it from an edge that could damage it.
As with most robot vacuums nowadays, there’s a handy smartphone app to download to help you keep on top of the i3’s tasks without having to be in the vicinity. Use either the app or your voice assistant to personalize your Roomba’s schedules and let it take care of the rest.

iRobot Roomba i4 Robot Vacuum
The Roomba i4 is similar in almost every way to the i3. It has the same 3-stage premium cleaning system and rubber brushes, 10X the power of other robot vacuums on the market, and even the same Braava jet m6 robot mop to help simultaneously sweep and mop your floors to a sparkling finish.
It’ll navigate your home in neat rows, thanks to its expert navigation system. This system will also stop the robot vacuum from getting caught in those pesky corners.

So What are the Differences Between Each Model?
Well, for starters, the Roomba i4 comes with two extra filters.
These filters are perfect for households with members who suffer from allergies and want a fresher atmosphere. It’s also even better for pet owners who don’t want their pet’s odors lingering throughout the house.
The i4 also comes with a virtual wall and a two-year warranty.
One Last Thing
It’s important to note that there is an extra accessory that can be bought for the Roomba i3: the cleaning base. This cleaning base is the perfect addition for you if you want to forget about vacuuming completely for a few weeks at a time.
It’ll take care of the i3’s dust cup so you don’t have to empty it for up to 90 days, and it’ll keep your i3 out of the way but ready to go.
The base isn’t included in the price though, so it’s an extra that you’ll be paying more for. Whilst it’s a handy extra to have, it’s not the most cost effective addition. This leaves it to be a completely personal choice at the end of the day.

Conclusion
Both Roombas are incredibly nimble and hard-working. They’re the perfect addition to any home that wants a quick and easy solution to vacuuming.
Both robot vacuums are essentially the same. In our opinion it’s not worth spending some extra bucks on an extra filter or AA batteries. You’ll get an amazing clean no matter which you choose though, which is the important thing.
