The Winner – Roomba 675
Considering cleaning performance, features, and overall value, it’s hard to overlook the performance of the Roomba 675. Unless you specifically need the benefit of the virtual wall barrier, the Roomba 675 is mostly identical to the slightly more expensive 690 model. For a robot vacuum with great cleaning performance, long battery life, wifi connectivity, and voice control capability, the Roomba 675 is a great option.
- Price: The Roomba 690 is slightly more expensive under normal pricing conditions.
- Virtual Walls: The Roomba 690 comes with a dual-mode virtual wall barrier, while the Roomba 675 does not.
- Aesthetics: The Roomba 690 is a light silver color with black accents and the Roomba 675 is a dark gray color with black accents.

Roomba 675 vs. 690 Design
The design of the Roomba 675 and Roomba 690 is basically identical, with only slight differences in the color. The Roomba 675 has an all black aesthetic, while the Roomba 690 uses a combination of black and light gray.
The buttons are the same, including a central “CLEAN” button, a spot clean button, and a dock return button. Additional settings and features can be accessed through the iRobot app on your smartphone.
In addition to the buttons on the top surface of the Roomba, both the 675 and 690 have the same release for the dust bin and filter as previous models.

Across the board of robot vacuums, this is a pretty average size, and does a nice job of maneuvering most areas. For more size comparisons and reviews, see our full list of robot vacuum reviews.
Accessories & Parts
Both of these models include the following parts and accessories in the box:
- Robot Vacuum
- Charging Station
- HEPA Filter (x2)
- Cleaning Tool
- Spinning Brush
- User Guide
The accessory the separates these two models is the:
- Virtual Barrier Wall (dual mode)
The virtual barrier wall is used to block off certain areas of a floor plan that you don’t want Roomba to access. This can be a useful tool when cleaning larger floor plans or complicated layouts with numerous obstacles.
VIRTUAL BARRIER | The dual-mode virtual barrier is capable of blocking off a linear path up to 10′ long or a radial area up to 4′ in circumference. This helps to protect a variety of areas including hallways, open concept wide spans, as well as sensitive areas around pet food areas or other furniture.
Roomba 675 vs. 690 Performance
So we’ve looking at the outside—now let’s dive into the inside and analyze cleaning performance.
Performance of each of these vacuums is based on a number of factors, including:
- Brushroll style
- Filtration system
- Cleaning tests
Each of these factors work together to establish the overall cleaning performance.

The bristle style does offer a lower price point, and cleans well on hardwoods, but tends to struggle with fine debris types on carpeted floors.
What is it?
This system is slightly less efficient than its successor, the AeroForce system. But that’s not to say that the AeroVac is bad by any measure. The AeroVac filter is still a HEPA filter.
Battery & Motor
The Roomba 675 and Roomba 690 come with the same 1,800 mAh battery and use the same motor (at least from what we can tell during our research).
And the run time is?
Both Roombas have the same 90 minute run time.
All of these details listed above help to determine the overall cleaning performance of each model.
Due to the striking similarities between the Roomba 675 and Roomba 690, we can assume that the cleaning performance would also be virtually the same. Below, we have pulled all of our cleaning testing data for the Roomba 690.
A full cleaning performance test here at Modern Cycle consists of 12 different tests; that’s four different debris types (cereal, kitty litter, rice, and sugar) and on three difference flooring types (hardwood floor, low pile carpet, and high pile carpet).

Hardwood Floor Cleaning Tests
Cleaning performance on hardwood floor was excellent. The Roomba 690 was able to remove 95%+ of all debris types.
- Hardwood – Rice 99% 99%
- Hardwood – Cereal 100% 100%
- Hardwood – Kitty Litter 96% 96%
- Hardwood – Sugar 95% 95%
Low Pile Carpet Cleaning Tests
Overall cleaning performance on low pile carpet was great as well, with 3 of the 4 tests scoring 98%+.
Cleaning performance on sugar wasn’t great, scoring a 72%. However, this is still a fairly good score for most robot vacuums. The ultra fine sugar particles are difficult for robovacs to remove.
In order for a robot to remove sugar particles in carpets you have to step up to a more expensive pricing tier.
- Low Carpet – Rice 100% 100%
- Low Carpet – Cereal 100% 100%
- Low Carpet – Kitty Litter 98% 98%
- Low Carpet – Sugar 72% 72%
High Pile Carpet Cleaning Tests
Lastly, cleaning performance on high pile carpet mirrored what we saw with low pile carpet cleaning tests.
99%+ of debris was removed on 3 of our 4 cleaning tests. The one problem area again was the sugar tests, which only scored a 66%.
Again, this is still a pretty good score for a robot vacuum. Most robot vacuums really struggle with sugar on carpet.
- High Carpet – Rice 99% 99%
- High Carpet – Cereal 99% 99%
- High Carpet – Kitty Litter 99% 99%
- High Carpet – Sugar 66% 66%
How to get started?
Starting a cleaning is as easy pressing the “CLEAN” button on the vacuum itself, scheduling a cleaning on the app using your smartphone, or even simply saying “Roomba, clean” (provided you have Alexa or Google voice setup).
The Roomba 675 and 690 are compatible with Amazon Alexa and Google Assistant for hands-free voice control (when paired with a voice control device like the Amazon Echo or Google Home.
Both the Roomba 675 and the Roomba 690 are able to connect fully to the iRobot Home app for full wireless controls. Using the app, you can start or stop a current cleaning, view cleaning history, or schedule a cleaning in the future.
Setup to the app is also easy. Below are some of the setting and control views on the iRobot app.
As mentioned above, the Roomba 675 and 690 model have the same physical buttons on the face of the vacuum. This includes:
- “CLEAN”: Immediately begins a cleaning cycle
- Spot Clean: Cleans in a circular pattern, growing increasing wider until the area has been sufficiently cleaned
- Dock: Returns the Roomba to the charging station to juice up
Since both the Roomba 675 and Roomba 690 are identical in size, maneuverability from that perspective is basically the same. The other factor that comes into play when considering maneuverability, is navigation technology.
What is iAdapt?
Both the Roomba 675 and the Roomba 690 operate with iAdapt 1.0 technology. Roombas in the 800 and 900 Series generally have the iAdapt 2.0 navigation technology while the newest Roomba i7 and Roomba i7+ employ the most advanced navigation, iAdapt 3.0.
What do you get with advanced navigation?
With advancements in navigation comes the ability the see obstacles before they hit them, advanced memory mapping, Imprint Smart Mapping, and the ability to remember digital maps of different floor plans. For more information on iAdapt 3.0 see our Roomba i7+ review.
The Roomba 675 and 690 is a more basic approach, basically “Bump and Continue”. Both models have edge sensors on the underside of the robot to prevent the robot from driving off of drop zones, like stairs or lofted space. But outside of these sensors, the cleaning pattern is sporadic, zig-zag, and a bit unpredictable.
Despite this random approach, the cleaning performance above shows these models with base level navigation still clean up an astounding amount of debris from the cleaning tests.
Which is the Better Value?
What’s the difference?
The Roomba 690 is slightly more expensive, but includes the virtual barrier wall, an accessory that is not included with the Roomba 675 model.
That said, for smaller floor plans or simpler layouts, you may find that you don’t need a virtual barrier anyway. In these cases, it could be a better value to forgo the additional costs and enjoy the savings, without the virtual barrier.
But at the end of the day…
Keep in mind that if your environment changes, the Roomba 675 is compatible with dual mode virtual barrier walls if you ever decide to add them. No pressure to feel like you have to decide immediately.
