In this article, we will talk about two very popular robotic vacuums Deebot N79s vs Roomba 671.

Nowadays, you can find thousands of different cleaning devices available on the market. There is everything from standard vacuums to automatic carpet cleaners. The manufacturers continuously improve their products, in order to make them both more affordable and more advanced.

Robotic vacuums are a great example, since a couple of years ago, those products were not only rather expensive but also they didn’t work that well. However, this has changed, and the manufacturers now offer a wide range of very efficient and reliable products. Comparing all of them would be impossible, that’s why we always focus on the most popular brands.

Today, we will talk about two very popular units – Deebot N79s vs Roomba 671. Both vacuums are a common choice among many beginners to this type of cleaning, mainly because of their price. They are not only quite affordable but also they offer great performance.

Either one of them should be a perfect choice if you don’t want to invest a fortune into a single product. Of course, those aren’t top-shelf vacuums, that boast all the most advanced features, however, they still get a job done.

Without further ado, let’s get into the proper part of the comparison.

Deebot N79s vs Roomba 671

Main differences

In the beginning, we would like to address, that either one of those products should be more than sufficient for everyday cleaning. In fact, we are convinced, that most people should be fine with either one. That being said, there are a few key differences, that you should keep in mind.

The first major difference is suction power. Typically, the more suction a vacuum has, the better. This is because models with higher suction are much better at removing deeply embedded dirt and debris. They are also capable of cleaning larger particles and removing all kinds of pet hair (if combined with a good brush).

Deebot N79s is a winner here, offering up to 1000 Pa suction which should be more than enough. Roomba 671 is capable of producing only 600 Pa – This power is great for everyday, light cleaning, although, it may not be sufficient for some heavy-duty cleaning.

Another important dissimilarity is the navigation system. This time Roomba 671 performs better, thanks to the more advanced navigation system. The vacuum analyzes the best possible cleaning path and also suggests personalized cleaning schedules by learning your cleaning habits.

The navigation in Deebot N79s still works fine, however, it’s based completely on random patter. The vacuum bounces around until the whole area is covered. The systems mentioned above were implemented because there is no mapping in both vacuums.

The next crucial difference is battery life. The battery is the main factor limiting maximum cleaning time, therefore, if you own a big household or you want to cover a large area all at once, it’s definitely something to consider.

Deebot N79s can operate for up to 110 minutes while the Roomba 671 can only run for 90 minutes. Both vacuums have a pretty good total runtime, compared to other units in this price range. Another thing to keep in mind is the “auto-recharge” function present in both vacuums – It allows them to go back to their docking station, recharge, and continue cleaning without your help.

The last dissimilarity is dustbin capacity. Most of the time this won’t make any difference when it comes to the maximum cleaning time, as the vacuums tend to run out of battery sooner than from empty space in the dustbin. Nonetheless, it’s something to consider if you don’t fancy emptying the dustbin too often.

Deebot N79s has a dustbin capacity of 450 ml. (15 oz.) while the Roomba 671 has a dustbin capacity of 350 ml. (11.8 oz.). We also highly recommend emptying the dustbin regularly, before it reaches its maximum capacity, in order to keep the unit working properly.

Those are pretty much all the crucial differences, that you should know about. Based on the factors above, you can already make the final decision. Although, we still highly recommend to continue reading, in order to learn more well-detailed information.

Cleaning performance

Cleaning performance is one of the most important factors when comparing robotic vacuums. By this, we mean how well a particular unit does, compared to other vacuums from a similar price range.

We have to say, that both vacuums do a pretty good job in everyday cleaning. They remove most of the dirt and debris, that could be seen on the floors. What’s more, the dustbin fills with dust and dirt, even when none can be seen on the floors.

Even though Roomba 761 is a less powerful unit boasting 600 Pa suction, it still gets rid of all the dirt and debris on the floors. Its competitor, Deebot N79s offers 1000 Pa suction – This much power could be particularly useful on all types of rugs and carpeted areas.

Another aspect, that hugely influences overall cleaning performance is navigation technology. This system is better in Roomba 761, as the unit analyzes the room and picks a somewhat efficient path. What’s more impressive is the fact, that this unit also learns your cleaning habits and suggests cleaning schedules.

Even though Deebot N79s can also have a scheduled cleaning, it won’t be offered to you automatically. This unit also navigates by choosing a random path until the whole area is covered.

Both vacuums, unfortunately, don’t have any mapping technology, therefore, you can’t create any in-app virtual keep-out zones. Although, you can use a “Dual Mode Virtual Wall Barrier” which is a beacon type device compatible with Roomba 671. This is the only convenient way to create a barrier, that won’t be crossed by the vacuum.

A great common feature in both Roomba 671 and Deebot N79s is the “Auto-recharge” function, which allows them to get back to their docking station, recharge, and continue cleaning afterward. This makes the battery life a little less important.

The vacuums also boast multiple cleaning modes, some of those are spot mode (vacuum focuses on the current area), single room mode (vacuum doesn’t leave the room), edge mode (vacuum cleans along the edges of walls and furniture), and standard auto mode (used for whole-house cleaning).

Those are pretty much all the most important aspects of cleaning performance. Of course, there might be more in-direct factors, that influence the overall performance, however, we will talk about those in the latter part of the article.

Capacity

Capacity, as we mentioned earlier, most of the time won’t influence the maximum cleaning time. Nonetheless, it’s definitely something to keep in mind, if you don’t fancy emptying the dustbin too often.

The capacity of Deebot N79s is 450 ml. (15 oz.) while the capacity of Roomba 671 is somewhere around 350 ml. (11.8 oz.). In both vacuums the capacity should be sufficient, allowing for a couple of days of light cleaning. That being said, the Deebot won’t have to be emptied as often as Roomba.

Noise level

Noise level is an aspect, that many people skip, however, we always take this factor into consideration. After all, robotic vacuums were created in order to free up our time, therefore, an extra loud unit running in the background may be quite distracting.

The noise level of Deebot N79s is somewhere around 64 dB while the noise level of Roomba 671 is somewhere around 62 dB. We advise taking those numbers with a grain of salt, as this factor is pretty hard to measure. Nonetheless, Roomba 671 seems to be a little quieter unit.

In order to make this more understandable, 65 dB is a noise of a little louder conversation or a microwave operating. This can be quite distracting if you are anywhere near the vacuum, however, if you are in another room, this shouldn’t bother you too much.

Remote control features

The manufacturers usually offer multiple remote control features, in order to make using their vacuums more convenient. Things such as voice commands, remote controllers, or special apps are standard nowadays.

There is no exception in models from today’s comparison – Both Deebot N79s and Roomba 671 offer multiple remote control features such as smartphone app, Google Assistant, and Amazon Alexa compatibility, and remote controller.

With the official app, downloaded from the manufacturer’s website, you can not only navigate the vacuum but also receive notifications.

Battery life

Battery life is one of the most important aspects when comparing robotic vacuums, as it determines maximum cleaning time. Therefore, if you own a big household, or you want to cover a large area all at once, it’s definitely something to consider.

Deebot N79s can operate for up to 110 minutes which is a great choice, especially considering this price range. Roomba 671 also doesn’t stick out behind, offering 90 minutes of maximum runtime. Either one of those units should satisfy an owner of a regular size household.

A different thing to keep in mind is the “Auto-recharge” function, which allows the vacuum to go back to its docking station, recharge, and continue cleaning afterward. Everything here is done automatically, and you don’t have to worry about manually charging the unit.

Design

Design is a crucial part of every robotic vacuum, as they need to fit under and around most of the furniture. What’s more, the design also needs to remain convenient and easy to use most of the time. Thankfully, both vacuums meet the requirements mentioned above.

If you would like to learn some more technical information, the Deebot N79s measures 13.90 x 13.90 x 3.11 in. and weighs 9.48 lb. Its competitor – Roomba 671 – measures 13.4 x 13.4 x 3.54 in. and weighs 6.8 lb. As you can see, both units are quite portable which is a small advantage.

Price

The price is another crucial aspect, however, it’s also usually the first thing people check when comparing different vacuums. Therefore, you may already know the price difference – Nonetheless, we still decided to touch on this aspect, as it’s very important.

Deebot N79s can be found on Amazon for the price of $269.00 (Click here to see the current price!) while the Roomba 671 can also be found on Amazon for the price of $250.00 (Click here to see the current price!).

We always highly recommend double-checking the price, as it tends to fluctuate a lot. What’s more, there are often discounts on Amazon, so it’s definitely something to keep an eye on.

Necessary maintenance

Maintenance is something, that many people don’t pay attention to when buying a new robotic vacuum. In our opinion, it’s a big mistake, as in order to keep your new unit operating at the desired level and prevent permanent damage you have to take basic maintenance steps.

We won’t be getting into details here, as it would simply make the whole article too long. We will, however, give you a few basic maintenance tips, that should work for most of the robotic vacuums.

In order to keep your new robotic vacuum operating at the desired level, you will have to:

Regularly clean/rinse all the brushes
Regularly check the brush roll and side brushes for any stuck dirt and/or debris
At least once a week clean the cover of the vacuum/wheels
Replace any used or damaged elements as fast as possible
Regularly empty and check the vacuum’s dustbin for any stuck dirt or debris

Once again, we highly recommend reading the user’s guide in order to learn all the crucial maintenance steps.

Conclusion

In conclusion, both vacuums are quite efficient and reliable, what’s more, either one should be more than sufficient for every day, light cleaning. That being said, there are a few key differences, that you should know about before you make the final decision.

Some of the most important differences are suction power (Deebot N79s has 400 more Pa suction), navigation system (Roomba 671 has more advanced navigation), battery life (Deebot N79s has 20 minutes longer battery life), and dustbin capacity (Deebot N79s has 3.2 oz. more capacity).

Based on the factors above, we would say, that the Deebot N79s is a winner of this comparison. The only weak point in this vacuum is the navigation system, however, it’s not much worse than the one in Roomba 671. All other aspects speak in favor of the Deebot product which makes the choice easier.

We hope, that after reading this article, you will be satisfied with your final choice.
