BottomLine: Speaking of the normal price difference between these models (insignificant when compared), it is wise to go with the all-wrapped Roomba 692.
Excluding the accessories and extra attachments difference, everything is the same with the 675 and 692 models.
And to state, with the Roomba 675, you can purchase those accessories separately.
Intelligent Adaptive Navigation – But Without Path Planning
Roomba 675 and Roomba 692 are designed with intelligent navigation. This means the robotic cleaners are capable of adaptive navigation.
The Roombas will continue to operate as long as there is no obstacle detected and adapt their ways around a tight spot.
Even getting under or around furniture is not a problem for intelligent robots.
Regrettably, Visual mapping is not a feature included with these Roombas. Therefore, path planning is impossible, which means the 675 and 692 only moves randomly while adapting to their environment.
A suite of precision sensors is included in Roomba 675 and Roomba 692.
The cliff sensor allows the robot to work close to the edges without tumbling down.
Furthermore, the Roombas have decent collision sensors that prevent the robotic cleaners from bumping into furniture.
However, the 675 and 692 are missing the carpet boost sensors and full bin indicators.
The Roombas automatically senses when there is an area packed with dust.
The sensors signal Roomba to perform additional cleaning on tough stains like places where there is much movement.
Decent Suction Power and Cleaning System
Roomba 675 and Roomba 692 are designed to output decent vacuuming force.
Although not as strong as their advanced models, the Roombas get the job done removing dirt and pet hair from hard floors and carpets.
Even stubborn stains are cleaned (after one or two rounds of vacuuming) by the 675 and 692 thanks to its decent suction force.
The Roombas are featured with a 3-stage cleaning system.
Their dual multi-surface rubber brushes are very efficient in scrubbing hard floors and dislodging dirt hidden in carpets.
Coupled with the suction force and edge-cleaning brushes, the cleaning system is quite effective at keeping your home tidy and spotless.
Scheduling is simple with the Roombas. You need to arrange the cleaning time and routines using the iRobot Home App, and the 675 and 692 will adhere to your plan every day.
Auto-adjust cleaning head
The auto-adjust cleaning head of Roomba 675 and Roomba 692 allows it to cross between carpeted and non-carpeted floors seamlessly.
As the robotic cleaners vacuum the floor, the auto-adjust head stays constantly engaged to the floors to make sure no spot is missed.
Auto Recharge, Battery Life
One of the unique features of Roomba robotic cleaners is their automatic recharging feature.
Once a low battery level is detected in Roomba, they run to their respective charging base stations. The smart cleaners will dock themselves for charging.
Speaking of the mid to high-end models (not 675, 692), they even return to precisely where they had left off and resume cleaning.
A full charge for the 675 takes 120 minutes, whereas Roomba 692 needs only 110 minutes. And they run for around 90 minutes each.
Usually, cleaning of a single level can be accomplished within the duration unless some focused cleaning routines are required.
One Roomba supports Virtual Wall Barriers

If you need the Roomba to keep off from a certain room or an area, you can easily arrange it with Roomba 692. You will get a virtual wall barrier with this model.
Place them around an entrance or a zone to prevent the robotic cleaner from approaching it.
Now the kid’s playroom or your pet’s food containers are protected from Roomba 692.
Unfortunately, Roomba 675 does not come up with any virtual wall barrier. To say this is the only considerable difference.
The One with Better Anti-allergy filter
Roombas 675 and 692 are perfect robotic cleaners that filter the air in your house while working.
The 675 comes with a standard filter, while Roomba 692 is equipped with an AeroVac filter.
When it comes to trapping pet allergens or minute dirt particles, the filter of Roomba 692 does better.
Whose Dirt Compartment has more Storage?
You are ensured more than one round of cleaning with Roomba 692 as it is equipped with a 0.6L-dust bin.
Meanwhile, the 675 has a 0.35 L dirt compartment that is almost half the size of Roomba 692’s bin.
You don’t need to worry about emptying the bin of Roomba 692 as frequently as you would with the 675.
A handle to carry the Roomba – 692 lacks it
Although both robotic cleaners do not weigh that much, carrying Roomba 675 is much easier thanks to its built-in handle.
With Roomba 692, you need to support the robot vacuum from underneath if you need to relocate it.
Customized Cleaning Recommendations
Another similarity between Roomba 675 and Roomba 692 is customizing the cleaning recommendations.
Based on your preference, you can personalize the cleaning recommendations you want the Roomba to notify you.
Irobot advanced algorithms recommend a cleaning cycle; if there is any event it senses, a notification will be delivered to the iRobot Home App.
Cleaning efficiency on hardwood, laminate, and tiled floors
After a few trials, it was proven that Roomba 692 performs better when vacuuming hardwood or laminated flooring than Roomba 675.
The former is more capable of removing dirt from the hard surfaces thanks to its cleaning system.
Adjust the exact vacuuming power you need
Another cool feature offered with these Roomba models is the adjustable vacuum force.
If you wish only to clean carpeted areas of your home, yank up the suction power to the maximum setting and watch the Roomba go.
Change your mind after that? Not a problem as you can bring down the vacuuming force to a lower level for cleaning the hard floors.
Dictate where your Roomba should go (App & Voice-Based Control)
Once you pair your smartphone with the iRobot Home App, you can control Roomba 692 and 675 models with an app-based remote control!
Interestingly, it is almost like controlling an RC vehicle. If the 692 or 675 gets stuck at all, you can get it out of the tricky situation by remotely controlling it from just your smartphone.
No need to manually correct it.
If you own smart home assistants like Amazon Alexa or Google Assistant, you can pair them with the Roombas for voice-based controls.
The next time you only need to speak up the cleaning instructions like “Alexa, ask Roomba to start cleaning,” and the smart cleaners will buzz into life.
Conclusion
We usually recommend reading the whole article before making any decision. But for this article, we do not.
As there is only one difference, it is completely out of point unless you want to know each feature clearly.
For small-sized houses, usually, we don’t see any requirement of a virtual wall barrier. But it completely depends on every house. No one can say that.
If you clearly think that there is a necessity then go with the 692 models. Otherwise, 675 is the model you can quickly check out.
But as these models are relatively close when prices are compared, we prefer Roomba 692 model to 675; you will get the virtual wall barrier and extra filters with the 692.
No need to purchase the filter the second time when there is a replacement needed.
