Deebot N79/N79S vs Roomba 690 Comparison

Deebot N79N79S vs Roomba 690

When you’re looking for a new robot vacuum cleaner, the decision is never an easy one. There are simply too many options to choose from, each with their own features, pros, and cons. Going with one that you haven’t researched properly is not exactly the right move to do, as you may encounter problems with the product itself.

So, to make your task easier, this article will take an in-depth look at three models, Deebot N79/N79S vs Roomba 690. We will compare them, and you will be able to determine which one works best for your needs.


The design may not be the most important thing to look for in a vacuum, but who doesn’t like an item that looks aesthetically pleasing?

When it comes to height, an ideal robot vacuum should be able to clean underneath your furniture as well, thus keeping every inch of your floor dust-free. Roomba has a height of 3.6 inches, being bigger than the Deebot models. As such, the Deebot ones have a greater chance of cleaning underneath the furniture and getting rid of the dirt that accumulates there.

The colors are different as well in these models. Our Deebot models have a grey finish that adds to the product’s beauty, as well as a glass cover. If you have pets, it may be funny watching them stare at their reflection on it.

As for the Roomba 690, there is nothing so special going on regarding the design, as it has the usual robot vacuum design. However, there’s one thing that makes it stand out – the solid construction. While its counterpart, Deebot, may get scratches on its fragile surfaces, Roomba is protected from that.

All these vacuums have a soft bumper at the edges that retract with small pressure. This is a system that protects the vacuum from self-inflicted damage, and the furniture from damaging as a result of the impact.

Features Deebot N79N79S vs Roomba 690


Both Deebot and Roomba are similar when it comes to the battery because both them run on a lithium-ion battery and need about the same recharge time. However, the Roomba only runs for 60 minutes, while the other one’s specifications say that it runs for about 100 minutes. Still, that’s not something set, as the high capacity of 2600mAh consumes more battery.

In other words, the specifications are not so accurate, as different factors may influence the intensity at which the battery drains. So, if the vacuum runs for shorter than expected, you shouldn’t be surprised.

Navigation and Mapping

Robot vacuums are amazing because it seems they have a mind of their own. You don’t have to watch over them all the time to make sure everything is going great. They have certain sensors that allow them to successfully remove the dirt in a path they create.

Therefore, the two models compared in this post have the same mapping system. They create the path and follow it. Moreover, they come with two systems that allow them to detect any obstacle in the way. While Roomba has iAdapt, Deebot has SmartMotion. Although they have different names, they are pretty much the same thing. They have sensors that allow them to detect things such as obstacles in the way or walls.

They also have an anti-drop sensor that lets them detect cliffs, so they can change the direction and find another route. As such, when the danger of falling is there, or when they hit obstacles, they can turn around and prevent any damage.

What makes everything even more amazing is the fact that you can restrict the vacuums from entering certain rooms. Sometimes, not every area of the house requires cleaning, and you want to focus on one room only. This is possible with these vacuums, as you can set them to focus on one room.


When the vacuum absorbs the dust from the floor, the goal is to get rid of it, not to release it back into the air, thus affecting the air and landing back on the floor. That is easily achievable with these two robot vacuums. They have filtration systems that don’t allow the contaminants to be released into the household air, being a great alternative for those who suffer from asthma or allergies.

In addition, they have different filters. The Roomba 690 has the Aerovac filter that reduces the debris and dust. Still, many buyers choose to improve the filter over time.

At the same time, the Deebot models have a high-efficiency filter. On their website, it’s specified that they reduce the airborne contributors that are associated with asthma and allergies. So, this is a huge plus for those who suffer from any of these conditions.

Deebot N79/N79S vs Roomba 690 Motor Noise

Deebot N79/N79S have motors that run pretty quietly. So, it won’t be an issue if you’re sensitive to noise. However, that causes them to clean less inconsistently as well. Each run is different, and the quantity of dirt they pick up varies with each outing.

On the other hand, Roomba 690 has a powerful motor that tends to cause more noise, but it’s also more efficient in picking up the debris and dirt.


Deebot comes with a multi-surface brush that allows a better dirt and debris pickup. It works on many types of floors, being effective in getting rid of more dirt. Still, it has one flaw – hair can tangle around it, requiring you to take care of it more often. It is needed if you want to keep it functioning in optimal condition.

On the other side, Roomba has a multi-surface brush as well, but it doesn’t have the same flaw as its counterpart does. It can operate on all floor types, and the hair doesn’t get tangled in it, which is a big plus.


  • They have multi-surface brushes that allow them to pick up dirt more efficiently.
  • The drop sensors are present in every model.
  • They have an automatic
  • The battery is a Li-Ion one in each model.
  • Each one can be scheduled.

Choosing the right robot vacuum for your household can turn into a real journey. There are just too many models with specific features and researching each one of them individually is time-consuming.

This article did the job for you and compared Deebot N79/N79S vs Roomba 690, thus giving you the possibility to determine whether a Deebot would be a better investment compared to a Roomba. They have a lot of similarities, such as the battery type, sensors, multi-surface brushes, and the Wi-Fi connection feature. However, they also have many differences, like the type of filters, runtime, height, Alexa compatibility, and noise.

Whichever you end up choosing after reading this post is up to you. Roomba seems like a better alternative. Still, if you want a similar and more budget-friendly product, Deebot allows you to enjoy most of the benefits for a lower price.
