The Roomba 690 and 891 have different color schemes and brush materials
These robot vacuums follow the traditional aesthetics and round shape of iRobot Roombas, although they do have slight design variations. Both house their remote system at the center of their faceplate, but their handles and colors are different. The Roomba 690 is available in silver and black and has a bigger handle while the Roomba 891 comes in champagne and black and its handle is moved closer to the CLEAN button. With a height of 3.6″, both Roombas can vacuum under low furniture with ease.
Both the Roomba 690 and 891 are equipped with a regular-sized dustbin that can hold up to 300mL of dust and dirt. Where the 891 has the edge over the 690 is in its high-efficiency filter that can help rid your home of allergy-causing particles such as pet dander and dust mites. Perhaps trying to make up for the lack of a high-efficiency filter, the Roomba 690 comes packaged with an extra Aerovacs filter.
A major upgrade found on the Roomba 891 is its dual rubber brushes that are designed to resist hair tangles better. Unlike in the 891, the dual brush rolls on the 690 is a combination of one rubber and one bristle brush roll. While both Roombas can handle hair better than most robot vacuums in their class, the Roomba 891 outperforms the 690 in this department.
The Roomba 891 boasts suction power that’s five times stronger than the 690
The 690 and 891 are equipped with iRobot’s signature essentials, which include the three-stage cleaning system, dirt detect technology, and cliff detect technology, to mention a few. All these allow the Roomba 690 and 891 to pull in dirt and work harder on areas that are particularly dirtier than the rest, making sure the areas are spotless. However, when it comes to vacuuming carpets and sucking in dirt and finer particles from crevices, the more powerful Roomba 891 does the job slightly better.
Both Roombas house sensors that allow them to navigate around obstacles, but they don’t have the advanced mapping and navigation capabilities higher-end Roombas offer. The Roomba 690 and 891 will randomly clean your home, and while they may seem to be confused at first, it’s nothing to worry about as they eventually cover and clean the whole floor.
The major difference between the two is there’s a dual-mode virtual wall barrier packaged in the 690. You can place this to protect areas you want the Roomba to avoid. The barrier has a standard linear mode (see inset above) and halo mode to create a barrier around itself. For instance, placing the barrier in front of a pet feeding area while it’s on halo mode will bar the Roomba from going around it.
Battery Life and Additional Features
Both the Roomba 690 and 891 work with smart voice assistants, can vacuum for up to 60 minutes, and can automatically dock as needed
The Roomba 690 and 891 promise up to 60 minutes of cleaning time on a full cycle, although expect shorter runtime if you have more carpeted floors. When running low on battery, both Roombas will trek back to their docking station so they can recharge. Unlike their more advanced siblings, the 690 and 891 cannot remember areas they have cleaned.
Both Roombas work with the iRobot HOME app and allow you to schedule cleaning and view cleaning history. This means your Roomba can vacuum on its own even while you’re away, just make sure its dustbin is not full when it starts. If you have a voice-activated smart assistant, you can connect them to the Roomba 690 and 891 for hands-free cleaning.
It’s worth upgrading to the Roomba 891, thanks to its superior cleaning power, brushes, and a high-efficiency filter
Whichever you choose, it’s hard to go wrong with the Roomba 690 and the Roomba 891. With that said, the latter comes out on top in this comparison as the 891 has stronger suction power, rubber brushes that can resist hair tangles better, and a high-efficiency filter. It’s a Roomba that best fits homes with pets, but any home will benefit from its features whether you have furry friends or not. Interestingly, despite having more advanced features, the Roomba 891 is more affordable than the 690 at the time of writing as it is on sale.
Meanwhile, the Roomba 690 may not be as powerful as the 891, but its virtual wall barrier is something many users find helpful. It comes especially handy if you have sensitive furniture or areas around the home that you need your Roomba to steer clear of. The Roomba 891 can be set-up with a virtual wall barrier as well, but that will require a separate purchase and increase its cost.
