Roomba Comparison Chart

Roomba Comparison

Roomba provides evolved through the years, and for this comparison, we’ll be comparing the latest models in their product line – the 615, 675, 690, E5, I3 960, I7, and S9.

Specific model ranges like the 700 and 800 series options are already discontinued.

So I’ll start with an overview of all Roomba models in this comparison.

Entry-level Roomba options

All robots in this category don’t have smart navigation. It only pinballs around in a random direction. The options here are split into two groups – 600-series and E-series. 600-series Roombas are equipped with the rubber and bristle combo. In contrast, E-series robots have newer rubber extractors that require less maintenance.

Similarities between iRobot Roomba robots

1. Counter-Rotating Brushes

Roomba counter rotating brushes

All Roomba products come equipped with counter-rotating brushes. This feature has been a staple for all their products since the earlier generation 500-series robots. The difference is that newer Roomba options have the bristle-less rubber extractors, whereas the older options (600 series) have a squeegee and bristle combo.

This combination has been proven in tests to clean carpets really well. The Roomba 690, even with its below-average airflow, was still able to pick up around a tidy 85.16% in deep cleaning tests with 100 grams of sand on mid pile carpet.

2. Dirt Detect

Roomba 980 dirt detect system at work.

Roomba products do so well in cleaning tests because the dirt detect system instructs the robot to focus on dirtier areas.

For instance, the 690 will go in a spiral motion around zones with more debris. Newer models like the I7 and S9 will do an extra back and forth pass.

3. Single Side Brush

Currently, all Roomba robots come with a single side brush. The design from the 614 to the I7 remains the same – three prongs with white bristled tips.

However, iRobot changed the design with the S9 due to the change in shape, where it used a five-pronged brush with shorter bristles.

4. Round Shape

Roomba Shape

Except for the S-series robots, all Roomba products have a round shape. Even the latest I3 robot retains this shape as used by earlier models.

I prefer the square front of the Roomba S9 because of its superior cleaning on the edges. It has the broadest brush of all Roomba products, which is a big reason it does well picking up debris on corners and edges.

5. Availability of Parts

Finding components for Roomba products won’t be a problem. It’s undoubtedly a significant factor why iRobot is so popular. Not only will you find consumables like the filter or brushes, but also harder to find components like the battery, side brush motor, wheel assembly, and more.

It doesn’t matter if you live in the United States or Asia. You can find these components in stores like Amazon, eBay, AliExpress, Lazada, and more.

As long as you do your due diligence with cleaning and maintenance, these robots will last a long time.

6. Warranty

All Roomba products come with a one-year warranty from iRobot. If you buy these products from stores like Amazon, you can avail of extended coverage.

But I don’t think that’s needed since these robots are easy to maintain and clean with its modular design where most of the components are easily accessible.

Differences between iRobot Roomba robots

1. Power/Airflow

Suction and airflow will vary with these products. For instance, the entry-level Roomba 675 and 690 registered less than 10 CFM in the airflow test. In comparison, the Roomba S9 has over 20 CFM.

Roomba ModelAirflow
Roomba S9:22 CFM
Roomba I7N/A
Roomba 98019.24 CFM
Roomba 9609.33 CFM
Roomba E56.98
Roomba 6759 CFM
Roomba 6908.2 CFM
Roomba 614N/A

2. Navigation

Earlier generation Roomba products like the 614, 675, 690, 860, 890, and E5 all utilize a standard algorithm, meaning it moves randomly.

It pinballs around until the battery goes down to 20% and then recharges. These models don’t have Recharge and resume, so it won’t resume cleaning until you press the clean button.

The first Roomba with smart navigation is the 980 model with its on-board camera and SLAM algorithm.

Unlike the older Roomba options, it runs in neat back and forth rows and has Recharge and resume, so it’ll resume where it left off after recharging if it didn’t finish the task previously.

However, it doesn’t have the smart imprint technology, so it won’t save the map or have advanced features like the keep-out zones and virtual wall that enable users to block the robot from off-limit areas virtually (through the app).

Newer models like the Roomba I7 and S9 take it further with the smart imprint technology to save maps (up to 10) and set off-limit zones. You can see the location of the robot in real-time through the iRobot Home app.

Here’s a summary of the terminology iRobot uses for each generation and what it means.

Adaptive Navigation [Roomba 614, 675, 690, E5]

It’s the most basic navigation utilized by older Roomba models. The robot will traverse in a random direction and relies on a series of sensors around and underneath to avoid obstacles and no fall off cliff points.

iAdapt 2.0 [Roomba 960 and 980]

Roomba utilizes a top-mounted camera to scan and pinpoint its location. Cleans in neat rows, so it’s more efficient. It has “recharge and resume” that automatically resumes cleaning if it didn’t finish the task previously. However, it can’t save maps. Users will not have access to convenience features like selective room cleaning and keep out zones.

iAdapt 3.0 [Roomba I7+ and S9+]

A step up iAdapt 2.0. Roomba will remember and save the map. This feature unlocks advanced features like selective room/area cleaning, keep-out zones, and more.

3. WIFI, Compatibility with Alexa and Google Assistant

Not all Roomba robots have WIFI, and these include the 614 and 860 models.

Other variants like the 675, 690, 890, E5, 960, 980, I3, I7, and S9 have WIFI and compatible with Alexa and Google Assistant.

Also, users will have access to the redesigned iRobot Home App, but features will vary between models.

4. Keep Out Zones and No Go Zones

Only Roomba products with the Smart Imprint feature have access to the keep-out zones.

This feature will prevent the robot from going into off-limit areas. Instead of using a physical barrier, you can use virtual walls to speak through the app.

5. Automatic Dirt Disposal

There are only three models currently available with an auto-empty system – the Roomba I3+, I6+, I7+, and S9+.

All three options have a specialized charging dock with a second vacuum that empties the robot’s dust container when it docks.

It has a bagged system capable of storing an equivalent of 30 bin fulls for dirt. iRobot says the bag will last for 30 days. However, that may vary depending on the size of your home and the frequency of runs.

6. Cleaning performance

Another difference between these robots is cleaning performance. One issue with the older Roomba variants like the 675 and 690 is the rapid spinning side brush that scatters debris to a larger area.

Deep cleaning results will also vary. The Roomba S9 is the best performing so far with a pick up of 94%, while the I7 was worst with a 79% score.

Other options like the Roomba 675 and 690 were in the mid-80s with the embedded sand on carpet test.

Regardless of which model you choose, expect decent cleaning performance on this surface.

Roomba products are also decent on hard floors. However, the rear exhaust tends to blow fluffier stuff like pet hair around.  It is more prevalent in earlier options like the 690.

Lower end options (600 series) won’t do as well as the higher-end options like the I7 or S9 because of the low airflow and random navigation.

7. Dimension

Unlike the Neato BotVac, Roomba robots vary with their dimensions. For instance, the Roomba I7 measures 13.34 inches in diameter. In contrast, the S9 is narrower – only 12.25 wide, so it fits more spaces. The older Roomba 690 is wider than the I7 and S9 at around 13.5 inches.

8. Run Time

Roomba products will have varying run time.

Roomba ModelRun Time
Roomba S9:120 mins.
Roomba I775 mins.
Roomba 980120 mins.
Roomba 96075 mins.
Roomba E590 mins.
Roomba 69090 mins.
Roomba 67590 mins.
Roomba 61490 mins.

The Roomba S9 and 980 will run the furthest at 120 minutes. In comparison, the Roomba I7 and 960 have the shortest run time at only 75 minutes.

Please note that the newer Roombas (960, 980, I3, I7, and S9) have recharge and resume, so run time won’t matter as much because it’ll automatically restart cleaning if it doesn’t finish vacuuming the whole area.

9. Brush roll

While all Roomba products use two counter-rotating brushes, there are variations. Older models such as the 614, 675, and 690 all utilize a rubber and bristle combo.

Roomba 675 counter rotating brushes

iRobot upgraded the 800 series robots’ design, putting in rubber extractors that didn’t have bristles.

iRobot utilized the same extractors in the 900 series and upgraded them further in the newer I and S-series robots with deeper grooves.

Roomba I6 Plus Extractors

The Roomba S9 has the widest brush of all Roomba products that span the width of the robot.

10. Dust bin capacity

The dust bin capacity will vary between the Roomba models. Options with the largest volume are the 960 and 980 – at around 600 ml.

In contrast, the 600 Series robots (614, 675, and 690) have the smallest – only 300ml.

Dust bin opening of the Roomba 675 and 690

The E5 and I3 have the next largest capacity after the 900 series at 500ml.

Roomba E5 dustbin close up inside

Lastly, the I6, I7, and S9 can hold up to 400 and 500ml of dirt, respectively.

Roomba I6 dustbin

Roomba I6+ dustbin.

Again, dust bin size doesn’t matter much for Roombas with the “auto dirt disposal system” because a second vacuum in the dock will empty it when it recharges.

Roomba I6 Auto Empty Station

So it frees you up from this task after every run. The bags incur an additional cost, but I think it’s worth it for the time savings.

Best Overall: Roomba S9+

Roomba S9 Plus

Pros

  • Outstanding at cleaning floors: The Roomba S9+ is one of the best options for cleaning hard floors and carpets.
  • Smart imprint navigation: This technology enables the S9+ to save up to 10 map levels and unlocks several features such as selective room cleaning and keep-out zones.
  • Wide extractors: The square front of the S9+ increases its efficiency, especially cleaning edges where it picks up better than other Roomba options.
  • Auto-empty: This feature is available in the “plus” version and automatically empties the robot’s dust bin after each run.
  • Excellent for pet hair: Another benefit of the wider extractors and higher airflow is its ability to resist tangles.
  • Recharge and resume: Automatically recommences cleaning if it doesn’t cover the whole area in the previous cycle.

Cons

  • Very expensive: The cost of an S9+ is equivalent to buying three or four high-end Dyson upright vacuums.
  • No mopping: None of the Roomba products have a mopping option like the Roborock S5 Max and S6 MaxV. You’ll need to buy an iRobot Braava, which is an added cost.

The S9+ is the most expensive Roomba option, but it’s one of the best robot vacuums when you factor in navigation, cleaning performance, containment features, and convenience.

It may not have the mopping capabilities of a Viomi V3 or a Roborock S5 Max, but it’s very good at what it does, which is sweeping up debris on floors.

This model is a complete ground-up redesign from the Roomba I7+. Gone is the round frame all Roomba products utilize before the S9.

I never thought iRobot would utilize a design similar to their main competitor, Neato, but their version is unique in many ways.

First, the S9+ utilizes counter-rotating brushes that are wider, giving it better agitation on carpets. If you compare the high-end Neato D7 and Roomba S9+, the latter has better pick up scores in embedded sand tests.

Second, the dirt-detect technology iRobot employs forces the robot to focus on the dirty area – another reason why Roomba does well on carpets.

Lastly, it has the auto-empty feature not found in any of the Neato robots, freeing up the task of manually emptying the dust container.

Bottom line

The Roomba S9+ is perhaps the best Robot vacuum, regardless of price. It offers superior cleaning performance on rugs, carpets, and hard surfaces. The smart imprint technology permits this robot to save up to 10 maps and allow users to set unlimited no-go zones, keep-out zones, and selective room cleaning. And the auto-empty system makes this a genuinely hands-free robot capable of keeping your home clean for weeks with minimal intervention.

Cheaper than the S9+: Roomba I7+

Roomba I7 Plus

Pros

  • Less expensive than the S9+: An excellent option for folks who want to enjoy the benefits of an S9+ without having to spend four figures on a robot.
  • Smart navigation: The I7+ retains the smart navigating features and map saving capabilities of the S9+
  • Empties the bin automatically: A second vacuum inside the charging base will clean the dust container’s contents.
  • Still excellent at cleaning floors: The I7’s lower airflow and narrower brushes translate to inferior pick up, but it’s still above average.

Cons

  • Not as good on carpets: Unfortunately, the I7 doesn’t deep clean as well as the S9+.
  • Still expensive: Even if it’s cheaper than the S9+, the I7+ is still more costly than most robot vacuums out there.
  • Not as good cleaning the edges: The round shape of the I7 hampers its ability to clean edges versus the S9.

Another Roomba option with the “Clean Base” station is the I7+. Like the S9+, it can empty its dust container thanks to the device mentioned above and has the same iAdapt 3.0 navigation. So it can also save maps, providing users access to containment features also found with the flagship S9.

The most significant difference between these two robots is cleaning dynamics – the I7 retains the round frame as older models. It presents the same limitations as other robots with the same shape.

It won’t be as efficient or clean the edges as well as the S9.

Still, the I7+ navigates in the same fashion as the S9, plus the dirt detect system makes it a viable alternative for people looking for a Roomba that can clean carpets without spending S9 money.

Bottom line

If the S9+ is too expensive, have a look at the I7+. This model offers similar navigational features as the flagship Roomba, but minus the wider brush and extra airflow. So it won’t be as good at cleaning carpets.

Cheapest Auto-Empty Option: Roomba I3+

Roomba I3

Pros

  • Least expensive with “Clean Base” station: The I3+ offers consumers a more affordable Roomba with the self-emptying feature.
  • Cleans in neat rows: Despite not having VSLAM, the I3 navigates in efficient rows thanks to its floor tracking sensor similar to the Roborock E4.
  • Decent bin capacity: The I3 can hold up to 500 ml of dry dirt.
  • Recharge and resume: Like the I7 and S9, the I3 has recharge and resume, making it the cheapest hands-free option if you combine it with the auto-empty system.

Cons

  • No iAdapt 3.0 navigation: This robot doesn’t have the on-board camera found in the I7 – users won’t have access to no-go zones or selective room cleaning.
  • Can’t save maps: The I3 won’t save maps as it lacks a camera or VSLAM.

The Roomba I3+ is the latest Roomba model released by iRobot and the least expensive alternative with the “Clean Base” station.

In terms of price, it sits right between the 960 and the flagship S9 models if you get the “plus” version with the auto-empty feature.

The I7 (without the plus) is less expensive than the 960 since it doesn’t have the top-mounted camera and VSLAM.

It won’t save any maps and doesn’t have in-app containment features available in the Roomba I7 and S9.

Bottom line

iRobot introduces the I3+, providing consumers a more affordable option with an auto-empty feature. However, it doesn’t have VSLAM and iAdapt 3.0 technology found in its more expensive siblings like the I7 and S9. So you can’t save maps, set no-go zones, or ask it to clean the dining room. But it’s cheaper, and it empties itself after docking, saving you time.

Smart Navigating, Can’t Save Maps: Roomba 960

Pros

  • An excellent option for carpets: The 960 is one of the better Roomba options for cleaning carpet. It picked up an average of 91% in the deep cleaning tests – better than the I7.
  • Large dirt capacity: The Roomba 960 and 980 have the largest capacity dirt volume of all the options here at 0.6 liters.
  • Cheapest option with smart navigation: This model is the least expensive with the top-mounted camera and VSLAM, so it moves around in straight lines.
  • Recharge and resume: Along with the I3, the 960 is the cheapest Roomba with recharge and resume.

Cons

  • Weak airflow: With around 9.33 CFM of airflow, the 960 doesn’t clean hard floors as other Roomba options with higher airflow like the S9 and 980.
  • Can’t save maps: The 960 only has iAdapt 2.0, which means you can’t save the maps.

The Roomba 960 is a “lite” version of the Roomba 980 with less airflow and a smaller battery. These downgrades affect its cleaning performance and range.

I tested the 960 extensively and found it to be a notch below the 980 in both cleaning surface and embedded dirt.

For instance, the Roomba 980 picked up 100% of sand on hard surfaces and 91.9% in the deep cleaning tests – higher than the 960’s score of 97.06% and 85.6%, respectively.

It only has iAdapt 2.0 that has the top-mounted camera enabling this robot to traverse in straight lines. But it doesn’t have the smart imprint technology, so you can’t save any plans.

You also won’t have access to the in-app containment features like no-go zones and keep-out zones.

Bottom line

If you don’t want to spend on the I7 or the S9 and want only the smart navigating functionality and not mind omitting the map saving feature, then the 960 is worth a look.

Better Value Than the 960: Roomba 980

Top view of the Roomba 980

Pros

  • High-airflow: With over 19 CFM, the 980 is very capable of cleaning various debris types – surface or embedded.
  • Excellent at cleaning embedded dirt: It picked up 91.9% on average in deep cleaning tests – one of the best robot vacuums at such.
  • Long run time: The 3300 mAh battery enables it to run for up to 120 minutes.
  • Large dustbin: It can hold up to 600 ml of dry dirt.

The Roomba 980 is an underrated option that doesn’t make in many “best robot vacuum” lists. It has more power than the 960 (more than double the airflow), so it cleans more debris with better efficiency.

This high airflow shows itself during cleaning tests, where it scored one of the highest marks of any robot vacuum I’ve tested – better across the board than the 960.

I’m not sure why iRobot isn’t promoting this model on their website over the 960, since it’s clearly the better performing product.

And good deals can be had for the 980 if you know where to look. The Roomba 981 and 985, in specific seasons, are cheaper than the 960. If you can it at a lower cost, it’s a no-brainer decision for me.

Bottom line

Between the 960 and 980, the better option for me, based on tests, would be the 980. The higher airflow combined with the larger capacity battery enables it to clean better for longer stretches. If you can find a sub-variant that’s cheaper than the 960, it’s a no-brainer option.

A Step Above the 600 Series: Roomba E5

Roomba E5 top

 

Pros

  • Resists tangles better: The rubber extractors in the E5 is the same one found in the I7 and I3 that resists knots better than the more traditional brushes in the 600 series.
  • 5-liter dirt capacity: The Roomba E5 dust container is larger than the Roomba 675 or 690. It’ll cover a larger area before you have to empty it.
  • Washable dust container: You can wash the E5 dust bin under running water thanks to the relocated motor.
  • Excellent on carpets: Rubber extractors enables this robot to pick up embedded dirt on carpets better (89.66%) than the Roomba 675 (85.1%) or 690 (85.16%).

Cons

  • Inefficient navigation: This Roomba lacks the smart navigating algorithm of more premium options (960, 980, I7, and S9), so it just pinballs around.

The Roomba E5 an upgrade over the 675, with the rubber extractors and a larger dust container.

Roomba E5 extractors

These upgrades address some issues with the 675 and 690 – hair tangles and small dirt capacity.

And you don’t need to pay a large premium for it. If you buy it from Amazon, you’ll only have to pay just a little extra for these upgrades.

As long as it’s under $300, the E5 is a better buy than the 675.

The rubber extractors will resist tangles better, and the dustbin holds close to 50% more dirt versus the 675.

Roomba E5 dustbin

Unfortunately, it retains the same random navigating pattern, so don’t expect it to be efficient.

But the upgraded brush and airflow should give this robot better overall performance on carpets or hard surfaces.

Bottom line

The E5 adds a high-end touch to the entry-level Roomba line thanks to the rubber extractors and larger dust container. It won’t traverse in straight lines like the Roomba I3 or I7, but the upgrade in airflow and brush make this a more viable option for budget robot hunters.

Entry-Level Options: Roomba 675 and 690

Pros

  • Great on carpets: Both robot vacuums are excellent at deep cleaning carpet.
  • Thorough navigation: The standard algorithm may be random, but it will cover the whole area with only a few missed spots.

Cons

  • Side brush spins too fast: One big issue with the 675 and 690 is the fast-spinning side brush that spins too rapidly. In numerous tests, it scattered large piles of debris.
  • Hair magnet: The bristle part of the brush is prone to hair wrapping on it. I wouldn’t recommend this model for pet owners.

I put these two models together because both are virtually the same robots. Each has the same motor, battery, brush, and dust bin capacity.

There are variances in the color scheme and dust bin latch, but those are just cosmetic.

The Roomba 675 and 690 will traverse in the same way, and both will struggle with hair (pet or human) because the more traditional brush design is a magnet for those types of debris.

One thing with Roomba products, regardless of price, is how good it is cleaning carpet.

The 690 and 675 were excellent at picking up embedded sand on mid pile carpet (85.16% and 85.1%, respectively).

These scores are in the upper echelon for robot vacuums and a good reason why these models are popular.

The 690 is no longer available on the iRobot website, and the 675 replaces it as their flagship entry-level option.

Bottom line

Consumers looking for an entry-level Roomba without the bells should consider the 675 or 690. It’s iRobot’s least expensive robot vacuum option. However, it only has the standard navigation, which means it’ll only pinball around. It will not remember maps nor has recharge and resume, so it’s just a basic robot.

Most Basic: Roomba 614

Pros

  • Least expensive option: The 614 is the cheapest and the most basic Roomba option.
  • Cleans carpets well: The 600 series robots are excellent at cleaning this type of surface.

Cons

  • No WIFI or App: Users don’t have access to the iRobot Home App. You’ll have to push the “Clean” button on the robot to engage the default cleaning cycle.
  • Inefficient navigation: Like the 675 and 690 above, the 614 will transverse randomly.

05/12/2021 11:45 am GMT

Lastly, in this comparison, we’ll have a look at the most basic Roomba option – the 614. It’s the most basic alternative iRobot has to offer.

This model doesn’t have WIFI, so users will not have access to the iRobot Home App.

It moves around like the 675 and 690 – in a random direction. All 600 series robots use the same rubber and bristle brush, so cleaning performance will not be far off.

Bottom line

The Roomba 614 is the most basic Roomba option, and it doesn’t even have WIFI, so taper your expectations. If you don’t mind not having access to the iRobot Home app, it’s an excellent cheap alternative that I’d recommend in small homes with lots of carpets.

Where can I buy these Roomba robots?

You can buy these robots in online stores like Amazon and Walmart. Please click on the links to check the latest prices.

Disclaimer: I’ll earn a commission when you purchase through any of the links above, but at no extra cost to you, so it’s a win-win for both of us.

Are Roombas worth the money?

Yes, Roombas are expensive relative to the features you’ll get from other brands. However, it has two features other robots don’t have, which I think is worth paying extra.

These are the dirt-detect and the dual brush system. Since iRobot has a patent on these features, other brands won’t be able to copy it. And based on tests, it’s what makes iRobot products great, especially at cleaning carpets.

Another reason Roombas are worth the money is the aftermarket support. You can purchase virtually any spare part, even for older models. The modular design makes it easy to replace components like the battery, side brush motor, and side wheels. You can even buy hard to find parts like the drop sensors on eBay.

The sheer availability of these components makes Roomba products an ideal option if you’re looking for a robot vacuum for the long term.

Do Roombas make noise?

Unfortunately, Roomba products are some of the noisier options in comparison with other brands like Roborock. For instance, the Roomba 980 went over the 74-decibel mark, which is Dyson territory.

The Roomba 690, even with the low airflow, produced over 65 decibels.

It’s a trade-off you should consider as Roombas will clean floors very well.

How does Roomba handle bumps and rugs?

Roomba products don’t have much climb ability. I tested it on five and eight-inch rugs. It was able to go over the shorter five-inch rugs, but going over the thicker eight-inch rug is a struggle – it has to approach at the right angle.

You may also want to remove light area rugs or use the keep-out zones (only available with the S9 and I7) since it’ll push these objects.

How does Roomba handle cords?

The short answer is it can’t. My advice is to tidy up those cords. None of the Roomba models can avoid cords or wires.

I haven’t seen or tested a robot vacuum that can completely avoid cords. The Roborock S6 MaxV came close, but it has blind spots, so if the cord falls into these zones, it won’t avoid them.

Which Roomba is the Best?

In terms of outright performance, convenience, navigation, and ease of use, the Roomba S9+ is the best Roomba option available.

However, the S9+ is really expensive, and not everyone can afford to buy such a high-tech robot.

You’ll have to find the right compromise between price and the essential features in the home.

The I7+ or the I3 are excellent alternatives to the S9 if you want a cheaper robot with the “Clean Base” dock that automatically empties the bin for you.

The I7 is more expensive between the two since it has camera-based navigation capable of saving maps. You’ll have access to advanced features like selective room cleaning.

In contrast, the I3 doesn’t have a camera and only relies on a floor tracking sensor for navigation. It cleans in straight lines, but it can’t save maps, and no access containment features in the app.

The Roomba 960 and 980 are in the next tier, with smart navigation but without map-saving features. These two robots can save maps, and there’s no access to the no-go zone and keep-out zones.

Lastly, the next tier is the entry-level options – E5, 690, 675, and 614.

These models will only pinball around the area. It doesn’t have the floor tracking or the camera sensor found in more premium Roomba options.

But these options are cheaper. Choosing one will depend on how much you’re willing to spend.

For me, the Roomba E5 is the option I’d select in the budget category because it’s got the largest dust container and extractors that resist tangles well.
