The DEEBOT N79S looks more sleek and minimalist, but the Roomba 690 has higher quality material and larger dustbin capacity

Overall, the iRobot Roombas are made of higher quality material than the ECOVACS DEEBOTs. However, Roombas also cost a lot more than DEEBOTs. Design-wise, most DEEBOTs have a clean, minimalist faceplate with fewer physical controls than the Roombas. Most ECOVACS are also lighter than iRobot’s robot vacuums.

The same goes for the two entry-level models we are comparing. The DEEBOT N79S is slimmer and lighter than the Roomba 690. Both can go under most furniture, but the N79S is slightly slimmer at 3.1 inches thick compared to 3.6 for the 690.

Another major difference between the two robot vacuums is their dustbin capacity, with the 690’s twice as large as the N79S. The Roomba 690 can hold up to 600 mL which means you don’t have to empty your dustbin as often as you have to when using the N79S. If you have a larger floor size or have bigger pets that shed a lot, a bigger dustbin will definitely come in handy.


Both Roomba and DEEBOT have smart navigation, but the Roomba 690 comes with a Virtual Wall Barrier

Both robot vacuums have their own intelligent motion technology and are equipped with cliff detect sensors to keep them from bumping into furniture or falling off stairs. DEEBOT’s Smart Motion technology boasts an advanced cleaning path while the Roomba will wander about your room in random directions (it still gets the job done!). Rolling over from bare floor to carpet is also not a problem for the N79S and 690.

Take note though that even with intelligent navigation capabilities, most robot vacuums tend to confuse dark flooring and carpets as “cliffs” so they might miss cleaning black areas.

Apart from the color, another major difference between the Roomba 690 and the DEEBOT N79S is the Virtual Wall Barrier that comes with the 690. The Virtual Wall Barrier will keep your robot vacuum from entering a room that you don’t want cleaning or areas that you want to avoid. This is especially helpful when you want to focus on cleaning one room first so you can empty the dust bin before it moves onto another or if you don’t want it to bump into specific furniture or items in a room (such as your pet’s stuff, for example).

Cleaning Performance

The Roomba has two main brushes and Dirt Detect technology. The DEEBOT has more cleaning modes that need to be manually selected.

iRobot Roombas, in general, have more powerful motors under the hood and their cutting-edge technologies are among the best in the industry. If you have thicker carpets at home, higher-end Roombas can suck dirt better than most ECOVACS DEEBOTs. However, most DEEBOTs are quieter than Roombas.

Both their entry-level robot vacuums boast of their own three-stage cleaning systems.

The Roomba 690 is equipped with a Dual Multi-Surface Brush and an Edge-Sweeping Brush. It also features Dirt Detect sensors that tell when an area has more dirt and automatically makes the robot vacuum work harder on that surface before moving on.

Meanwhile, the DEEBOT N79S does not have a similar Dirt Detect technology. Instead, it has four different cleaning modes–Auto Mode, Spot Cleaning, Edge Mode, Max Mode–that you can select to suit your specific cleaning needs. Unlike the Roomba, it only has one main brush with an additional two side brushes to keep those edges and corners spotless.

Runtime and Automatic Docking

Both can automatically go back to their docking stations, but the DEEBOT has a longer runtime

With a runtime of 100 minutes, the DEEBOT lasts a bit longer than the Roomba 690 with only 90 minutes of runtime on a full cycle. However, the 690 can run on a full cycle again after only 120 minutes of charging while the DEEBOT needs to be charged for 240 minutes.

They can both detect when they are running low on battery and go back to their docking station to recharge. They both occasionally may fail to dock though, depending on your floor plan. As they are only entry-level robot vacuums, both do not have the capability to resume cleaning and start where they left off once they’re fully charged. The newer, more expensive models of Roomba and DEEBOT come with said feature.

Control Options

Both have Wi-Fi and smart home connectivity

The Roomba 690 and the DEEBOT N79S are among the most pocket-friendly robot vacuums with Wi-Fi and smart home connectivity. You can control them through their own mobile apps and ask your vacuum to start cleaning no matter where you are. For a hands-free cleaning experience, you can connect them to Amazon Alexa or Google Assistant easily.

Using the ECOVACS app, you can control the cleaning modes of your DEEBOT N79S to customize your vacuuming to your cleaning needs.


ECOVACS DEEBOTs provide overall better bang for your buck

The technology, build, and overall quality of iRobot Roombas are still hard to beat, but they also come at a steeper price. On the other hand, ECOVACS DEEBOT’s technology and motor may not be as sophisticated, but they still provide great quality robot vacuums at more affordable price tags.

For its price range, the DEEBOT N79S does a great job of cleaning dust and debris and also has wireless capabilities. If you are on a budget, this robot vacuum is a great buy. If you want a Virtual Wall Barrier, a bigger dustbin capacity, and don’t mind paying around a hundred dollars more, the Roomba 690 is still priced reasonably for robot vacuums with these features.
