iRobot has replaced their older Roomba 900 series models of robot vacuums with their new affordable robot vacuum – the Roomba i3+ EVO and the base Roomba i3 EVO.

The only headline you need for the Roomba i3+ EVO is that iRobot just made the Cheapest Self-Emptying Robot Vacuum out there with the Smart Mapping feature.

The higher-end Roomba i7+ and s9+ are more expensive robot vacuums, so the Roomba i3 and i3+ are ones to get if you don’t have a high budget. The i3/i3+ give you many of the same smart features, including the great Auto-Emptying Clean Base station with the Roomba i3+.

If you’re in a hurry and choosing between the Roomba i3 vs i3+, go with the Roomba i3+ for the self-emptying dock and the feel of home cleaning automation. If you’re choosing between the Roomba i3+ vs i7+, go with the i3+ again because iRobot has stepped up their game to provide amazing value and performance in the Roomba i3+ EVO.

Roomba i3 and i3+ Features

I am reviewing the Roomba i3 and i3+ together because they’re essentially the same robot vacuum. The main difference is the self-emptying Clean Base unit that allows the Roomba i3+ to empty dust and debris itself. 

That’s similar to the Roomba i7 and i7+, as well as the Roomba s9 and s9+. The + Plus is important to have if you want the flexibility of not needing to be around to empty the Roomba to let it keep cleaning. The self-emptying base is the best thing I love about my i7+.

Let’s start off with the common features between the two affordable models, before getting into the details of the advanced features. 

Design and Size Dimensions

The Roomba i3 and i3+ are about the same size as the other mid-price robot vacuums from Roomba with the familiar circular design.

What I’m loving with the design on the top is that cool, textured gray circle that’s plastic, but feels modern to the touch. On top is the traditional Clean Button with buttons for Home and Spot Cleaning. The Power button is the same button for Cleaning.

They’re 13.26 inches wide by 3.63 inches tall, and weigh 7.44 lbs. Both are slightly smaller than the Roomba i7, but only by 0.05 inches. 

Battery and Capacity 

They both come with 1800 mAH lithium-ion batteries like the other Roomba vacuums to help it with recharging. They’ll clean for up to 75 minutes in testing and take about 2 hours to recharge.

Depending on the layout of your house with furniture and obstacles, the i3/i3+ should be able to clean a 600-800 square foot area on a single charge. There are other variables like floor types (carpet vs tile vs hardwood floors) that will affect the time it takes to clean.

Brushes and Rollers

iRobot’s patented, unique dual multi-surface rubber brushes make the Roomba i3 and i3+ great for homes with pets. The i3 picks up where the 960 left off with being great at picking up pet hair. 

If you have pets at home who like to shed their hair all over your floors and living room carpet, the i3’s green rubber carpet rollers get the pet hair so it doesn’t get tangled. The rubber on the brush rollers help to prevent entanglement of pet or human hair in the brushes and wheels. 

The brush rollers will adjust to different types of floors to stay in contact to pick up pet hair and other dirt and debris.

A specially designed edge-sweeping brush is also there to get dust balls along the sides and edges of walls and corners. 


Suction Power, Cleaning Technology and Filters

iRobot’s 3-Stage Cleaning System continues to power the Roomba line in the latest Roomba i3 and i3+. 

While the Roomba 960’s suction power was 5x the suction of the Roomba 600 series, iRobot stepped up the performance for the 960 replacement.

The i3 and i3+ have 10x the suction power, making this one of the many standout features. That puts it on the same level as the higher cost Roomba i7 and i7+. The s9 and s9+ robots have the strongest suction power.

That’s going to come in handy if you have multiple floor types like carpet and hard floors. Carpeted floors could use some extra juice when it comes to carpet, especially high-pile carpet. 

These two Roomba’s also have iRobot’s patented Dirt Detect Technology to find those dirtier areas in your house. The sensors will recognize more dirt and run over those areas more to ensure it’s clean. 

The i3 and i3 plus come with iRobot’s standard High-Efficiency Filters that trap 99% of dirt, dust mites, and cat and dog allergens. It’s not quite the 99.9% of HEPA filters, but it does do enough for me.

Navigation and Mapping

The Roomba i3 and i3+ come with Smart Navigation and Imprint Smart Mapping abilities like the i7/i7+ and s9/s9+. I love that iRobot added the Smart Mapping feature to the i3+ because it now makes the i3/i3+ models the best valued robot vacuums available.

Smart mapping lets the Roomba map your house and save that map for future cleanings and customizations. With mapping, you have custom cleaning control and you have customizable cleaning maps. It’s location-based cleaning.

Maybe the children’s bedroom gets dirtier quick. That’s where Room-Specific Cleaning is a great additional feature you might want.

One of the more sophisticated features is the ability to draw “Keep Out Zones” on the customizable floor maps. E.g., You don’t have to put away the dog food dishes before the cleaning job starts. You can now draw a square around it on iRobot’s mobile app and the Roomba will avoid that area. 

Previously, you could only use the iRobot Virtual Wall Barrier Accessory to create Keep Out Zones. These virtual walls are able to be used across iRobot’s Roomba product line.

When it comes to navigating homes, the i3 and i3+ have Smart Navigation with iAdapt 3.0 technology, similar to the higher-end models like the Roomba i7+ and s9+. The intelligent navigation tracking sensors allow the Roomba to navigate and map your home to create the most efficient cleaning paths. Imagine neat vacuum lines, rather than the random lines from Roomba’s budget-friendly robot vacuum cleaners, the Roomba 614 and 675

All rooms have furniture and other obstacles, but its Reactive Sensor Technology helps the i3 and i3+ avoid obstacles and getting stuck. You’ll need to worry less about it getting stuck under your couch or other furniture. 

The navigation is also used for the Recharge and Resume function. When the battery is running low, the Roomba i3 will find its way back to the charging station and recharge. Once it’s finished recharging, the i3 will pick up from where it left off.  

One other great feature is that the Imprint Smart Mapping syncs across other iRobot products like the Braava jet m6 for mopping to bring an extra level of cleanliness. The Braava will know what areas have been vacuumed, so it can mop those areas first.

iRobot Genius, Home App and Voice Control

The iRobot Genius Home Intelligence app is iRobot’s latest innovation to personalize the cleaning experience for users, from the convenience of their phone screens. The Genius app is a redesigned iRobot Home App with more features and functions to make it easier to keep floors clean. 

The Genius App for iOS and Android acts as your home cleaning command and control center. You will use the app to create customized cleaning jobs for the Roomba. The app also gives you cleaning reports and maps for a comprehensive cleaning history.

The scheduling feature gives users the ability to schedule cleanings and cleaning intervals for an automatic cleaning process.

iRobot Genius will suggest cleaning schedules and Clean Zone areas to you based off what it’s learned from your past cleaning habits. It can also make cleaning suggestions, which is great if you have allergies.

Voice commands are easy with voice assistants like Amazon Alexa and Google Home through compatible smart devices. 

Smart home automation is what I’m constantly striving for and the Genius app helps with that. You’ll be able to integrate with other smart home devices like smart locks if you want, including cleaning routines with IFTTT. 

Self-Emptying and Clean Base Station

Self-emptying only pertains to the Roomba i3+ because the Clean Base Automatic Dirt Disposal emptying station is needed. 

The 19-inch tall Clean Base Tower will need a couple feet of clearance when the lid is open. Best not to place the robot vacuum docking station in a low-clearance area, because it’ll make it tough to empty the Clean Base.

The Roomba i3+ will automatically empty its dustbin when full and like the i7, i7+, s9, and s9+ Clean Bases, it will hold up to 60 days worth of dirt and debris. The automatic dirt disposal feature allows these automatic dust collectors limit users’ exposure to dust.

That’s a long time, weeks and a couple months, before you’ll need to empty the AllergenLock bags. These bags that hold the dirt and debris uses four layers of material that blocks and traps 99% of allergens, including pollen and mold. 

If you ever need more dirt disposal bags, they’re sold on Amazon in packs of 3 for a low price.

Roomba i3 vs i3+ Pros and Cons


  • Roomba i3+ brings top performance and Self-Emptying capabilities to a mid-priced robot vacuum

Roomba i3 vs i7 (i3+ vs i7+) Comparison 

The Roomba i3 vs i7 and Roomba i3+ vs i7+ comparison may seem unfair, but there aren’t that many differences between the two. The main differences is the design and different camera sensors on the i7/i7+. The Roomba i3/i3+ is by far the better value now.

When the choice was Roomba 960 vs i7+, I preferred the i7+ easily because it was night and day with features and offered the better overall value. But the price difference and value derived were more significant between the 960 and i7+.

Roomba i3 vs i3 EVO

The hardware in the Roomba i3 and i3 EVO are the same, so it’s the exact same robot in terms of its physical components. The difference between the two i3 models is that the i3 EVO has smart mapping functionality. That will allow the i3 vacuums to remember your home’s floor plan and allow you to draw Keep Out Zones, as well as name different areas of the home for future spot cleans.

March 2022 Update: This post has been updated to reflect the exciting new firmware updates and new name for the Roomba i3 EVO and i3+ EVO robot vacuums. The Roomba i3+ and Roomba i3+ EVO are the same robot vacuum. iRobot added the EVO onto the name with the new firmware update that provides Smart Mapping functionality.

Roomba i3+ vs i3+ EVO

The Roomba i3+ and i3+ EVO models have the same hardware components. The differences are in the software and firmware. The i3+ EVO comes with the Smart Mapping feature that allows for smart navigation. That allows the i3+ EVO to remember your house’s floor layout, so it will be more efficient and cut down on cleaning times in future cycles. You will also be able to name different rooms and draw Keep Out Zones for the Roomba to avoid cleaning.

Roomba i3 EVO Review Final Thoughts

iRobot has done it again with the Roomba i3 and i3+ robot vacuums. If you have a slightly higher budget, the self-emptying solution on the Roomba i3+ is well worth it. 

I hope that this is the trend to provide more affordable self-emptying lineups of robot vacuums to the world. 

Also, if you’re looking for this in Costco, the Costco version is named the Roomba i4 (4150) model. Read the full Roomba i4 review. Costco’s i4 does not come with the Clean Base Automatic Dirt Disposal docking station though. So if you want the Clean Base, you’ll need to buy it on Amazon.

As I continue to do more reviews of standard robot vacuum companies, iRobot options just stand out. iRobot continues its development of models that help to bring the robot vacuum market up. Traditional robot vacuums and the old-school standing vacuums don’t really stand up to iRobot’s performance quality in making the robot vacuum space.

FAQs Frequently Asked Questions

What is the Difference between the Roomba i3 vs i3+?

The only difference between the Roomba i3 and i3+ is the Clean Base Automatic Dirt Disposal Docking Station that comes with the Roomba i3+. The Clean Base Unit allows the i3+ to self-empty dirt and dust into AllergenLock bags, storing up to 60 days worth of debris.

Does the Roomba i3+ Have Mapping?

Yes, the Roomba i3+ has Imprint Smart Mapping as of the March 2022 firmware update. The advantage of smart mapping is to have customized cleaning sessions and to draw Keep Out Zones. If you don’t need those, then the i3+ missing the mapping feature is a non-factor.

Is the Roomba i3+ Worth It?

Yes, the Roomba i3+ is definitely worth the price tag. It has the same features as the more expensive Roomba i7+. The new firmware update for the Roomba i3+ makes it the Roomba to buy because of it being the best value.

Can the Roomba i3+ Clean Multiple Floors?

Yes, the Roomba i3+ can clean multiple floors without a problem. It also has Imprint Smart Mapping that will let you create maps for each floor. That will allow you to customize future cleanings.

Roomba i3+ vs 981 Differences

The main difference between the Roomba i3+ and the 981 is the self-emptying feature on the i3+ with the Clean Base Automatic Dirt Disposal station. The price point on both the i3+ and the 981 are similar, so are the major cleaning, navigation, and mapping features. Unless the Roomba 981 is on a major sale, the Roomba i3+ with the Clean Base dock is easily the better value here.

Roomba e5 vs i3+ Differences

The Roomba i3+ and e5 have major differences, which is expected as the i3+ is at a higher price point. The Plus in the Roomba i3+ means that it comes with the self-emptying Clean Base Dirt Disposal Docking Station that will store up to 60 days of dirt and debris. If we look at just the robot vacuum itself, the Roomba i3 is a far better robot to the e5. The i3/i3+ has 10x suction power, while the e5 only has 5x suction. The Roomba i3/i3+ also cleans in neat rows for cleaning efficiency to save time and Smart Mapping capabilities, while the e5 has random navigation with no Smart Mapping.

If you are on a strict budget, the Roomba e5 will do a good job cleaning, but if you can, go for the Roomba i3 at a slightly higher price. If you have a higher budget, the Roomba i3+ with the Clean Base is the best value as it’ll give you that hands-off cleaning experience.

The Roomba i3 EVO model without the Self-Emptying Cleaning Station is even cheaper, but only lacks the self-emptying feature. iRobot has created the best value robot vacuum in its lineup and in the market.
