When can you honestly say that you thoroughly enjoyed vacuuming? Vacuuming is a tedious job that nobody (NOBODY!) wants to do. This is why the most genius men and women got together to create and program robots to do this annoying task for us.

Deebot N79S

Recently, there has been an influx of robot vacuum cleaners entering the market, from budget-friendly models that get the work done to models equipped with every feature you thought you needed and more.

In this article, we’re going to take a look at three different robot vacs – the Eufy 30C, the Ecovacs Deebot N79S, and the iRobot Roomba 690. These three belong in the middle ground in terms of price, but which of the three will reign supreme? Let’s find out.

Suction Power

Eufy 30C
The first thing to take into account when shopping for any vacuum cleaner is how well it suctions up dirt and debris. The Eufy 30C can suction at 1,500 Pa which is the same amount of power as many stick vacuum models.

Deebot N79S
The Deebot N79S has a maximum suction capacity of 1,000 Pa which is considerably less than the Eufy 30C but not too far from the average capacity of other robot vacs in its price range. Still, it would have been nice if this robot could suck a little better.

Roomba 690
Surprisingly, the Roomba 690 delivers the least amount of suction power of the three. It has a maximum Pascal rating of only 600. This isn’t insufficient in picking up loose dirt and fallen cereal, but it may not be enough to give your carpets the thorough cleaning you were hoping for.

Conclusion: In terms of suction power, the Eufy 30C is the clear winner with 33% more power than the Deebot and more than twice that of the Roomba. Basically, the Eufy 30C can pick up anything that the other robots can and much, much more.

The runtime measures how long the robot can perform its cleaning tasks between charges. Both the Eufy and the Deebot come with 2,600 mAh Li-Ion batteries that work for roughly 100 minutes before needing to refuel. When charging, it takes these robots roughly 3 hours to go from 0% to max capacity.

Roomba 690
The Roomba’s 1,800-mAh rechargeable Li-Ion battery delivers only about 90 minutes of usage per charge. Like the other two robot models, it takes 3 hours to go from completely empty to completely full.

Conclusion: When comparing their respective battery sizes and runtimes, we find that the Roomba’s battery has the best runtime-to-battery ratio. However, the extra 10 minutes that the Eufy and Deebot provide means more cleaning per charge, plus they all require 3 hours of charging.


Eufy 30C
All three of these robots come with the Auto-Docking feature. When the robot detects that its battery is low on juice, it’ll make a beeline straight to the charging dock to refuel. Even though the Eufy 30C has this feature, we have found it quite useless in this model. Most of the time, the robot will end up stopping in its tracks before it reaches the charging dock. This means having to manually place it in the charging dock like our cavemen forefathers did back in their day.

Deebot N79S and Roomba 690
Although the Deebot and Roomba do experience the same problem as the Eufy, it doesn’t happen quite as often. This means you don’t need to worry about whether your robot did its job before bringing your boy or girlfriend back to your crib to chill.

Conclusion: The auto-docking feature is useful only when it works. Unfortunately for the Eufy, making it back to the charging station is worthy of celebration. This means you’ll need to closely monitor the robot to ensure that it keeps its batteries fully charged and ready for the next cleaning session.

Cleaning Modes

Eufy 30C
The Eufry 30C comes with four different cleaning modes – single-room mode, edge mode, spot-cleaning mode, and auto mode. The single-room and auto modes are self-explanatory. Edge mode, the Eufy will crawl along the edges of a room while removing any clinging pieces of dirt. As for spot-cleaning, the robot will go around in a spiral, eventually reaching the center, to remove concentrated dirt piles.

Deebot N79S
The Deebot also comes with the same four cleaning modes available in the Eufy but with the addition of max suction mode. As you can already guess, the max suction mode is meant for picking up any pieces of loose dirt in low pile carpets.

Roomba 690
The Roomba comes with the standard selection of 3 cleaning modes – single-room, auto, and spot-cleaning. To get rid of debris stuck to the walls, the Roomba is equipped with side brushes but no edge-cleaning mode.

Conclusion: More cleaning modes don’t necessarily mean a robot vac is good or bad. However, with the addition of max suction mode in the Deebot, we find that it will give you the most bang for your buck, especially if you live in a particularly dirty place and have messy kids.

Downloadable App

Eufy 30C, Deebot N79S, and Roomba 690S
All three of these brands offer downloadable apps for your smart devices. With a push of a button or tap of your phone’s screen, you can tell any of these robots to begin or stop their cleaning cycles or even head back to their charging station to refuel. You can also program cleaning schedules via their apps, so that’s one less thing you need to worry about.

Eufy 11S vs. Eufy 15C vs. Eufy 30C


In all honesty, the Eufy 30C and its amazing 1,500-Pa suction power put it in a far lead compared to the other two. However, the problem with its auto-docking feature is what really kills it for us.

In our opinion, the iRobot Roomba 690 falls in between the two other robot vacuums.

For this reason, we feel that the Deebot N79S is the best of the three robot vacuum models discussed in this article. In addition, it also has a max suction cleaning mode for lifting even piles and piles of dust from your floors.
