The number of state-of-the-art robotic vacuum cleaners entering the market every year is mindboggling. With so many options to choose from, finding the right bot for your home can be one of the most confusing shopping experiences. Of course, you could always check out the top manufacturers and see what they’re producing.

Ecovacs Deebot N79W+ Robotic Vacuum Cleaner Review

Ecovacs, Asia’s number 1 producer of in-home robotic appliances and number 2 in the world (a step behind iRobot) has now slowed down after more than two decades in the industry. Their Deebot robotic vacuum series might contain just what you’re looking for.

In this article, we’re going to take a look at the Ecovacs Deebot N79W+, a mid-class series that works better than most at vacuuming hard floors and carpets. After reading this article, you should be able to conclude whether the N79W+ is the right fit for your home.



Small Profile and Shape

The N79W+ measures in at only 13 inches wide by 3.07 inches tall. It’s not the shortest robot that’s currently available, but it can travel below most couches, bed frames, and end tables to reach hidden piles of dirt and fallen food.

Like so many robotic vacuum cleaners, the N79W+ is disc-like in shape. This is not the most optimal design for handling corners and edges, but the two far-reaching side brushes do a pretty good job at pulling dirt into the vacuum inlet.

True HEPA Filter

Robot vacuum cleaners equipped with True HEPA Filters are not exactly hard to find, but we’re always excited to learn that a robot is compatible with such a filter.

The great thing about True HEPA Filters is their unparalleled ability to trap even the tiniest specks of dirt, allergens, and microorganisms. True HEPA Filters have an efficiency rating of 99.97% at capturing particles as small as 0.3 microns in size. Those suffering from seasonal or pet allergies will love the N792W+ magnificent filtering capabilities.

The True HEPA Filter is not washable, so if you decide on getting the N79W+, you’ll need to purchase replacement filters every three months or so.

Auto-Dock and Recharge

Convenience is a top priority for those of us shopping for robot vacuum cleaners. The worst thing about past models is that they could not charge on their own, forcing users to fetch the robot and place it in its charging station.

The N79W+ eliminates this problem with its auto-docking function. When the robot detects a low battery, it’ll stop what it is doing and make a beeline straight for the charging dock. It takes about 4 hours for the robot’s battery to reach maximum capacity.

Unfortunately, the N79W+ does not have an auto-resume function, so you’ll either have to press the button on the bot’s control panel or use the downloadable app or Alexa (more on these later) to tell it to get back to work. Furthermore, the robot will not pick up where it left off, so it has to start its cleaning cycle from the beginning.

Missing Smart Mapping and Navigation

It’s worth noting that the N79W+ is not one of Ecovacs’ top-notch robotic vacuum cleaners. Being a mid-class robot, it’s missing certain specs that make it a top contender in today’s robotic appliance market.

Examples of this are the N79W+’s lack of smart mapping and navigation technologies. Without these sensors, the N79W+’s only way of traveling across your floors is by going back and forth in an S-shape. The robot is incapable of creating a digital layout of your home, thereby using up more battery power to power its somewhat inefficient random pathing.

Not only that, but the N79W+ does not have dirt sensors. Without this, the robot will not make multiple passes over a particular spot to suction up every piece of dirt. If it misses a dirt pile, your only hope is that it’ll get it next time.

110-minute Runtime

Despite having a super-beefy 2,600-mAh battery, it has a limited runtime of only about 110 minutes. This is enough time to cover roughly 1,200 square feet per charge, making this unit perfect for small homes or apartments. The 110-minute runtime is not a disappointment at all, seeing as how many modern and older-generation robots deliver only about between 60 to 90 minutes per charge.

Large 520-mL Dustbin

One of the largest annoyances about owning a vacuum cleaner or robotic vacuum cleaner is dumping out the contents of the dustbin. Thankfully, the N79W+ comes with a tremendous 520-mL bin that stores roughly 3-4 cleaning cycles’ worth of dust. This allows you to leave the robot for days on end before the dustbin reaches full capacity.

Remote Control

The greatest thing about the N79W+ is how users can configure and control the robot. The N79W+ comes with its infrared remote control with simple functions like setting up cleaning schedules, select cleaning mode, start, stop, and charge.

If you lose the remote, you can get the Ecovacs Home app to give cleaning instructions and set up cleaning times. Also, the N79W+ has voice response via Alexa and Assistant. Simply shout orders (start/stop/charge) at your virtual assistant and the N79W+ will obey.

Adaptive Floor Sensing Technology

From the name of this technology, you can already guess what it does. The N79W+’s built-in sensors are constantly monitoring what surface the robot is currently cleaning and will adjust the suction power accordingly.

When the robot steps onto carpeted floors, it’ll crank up its suction power to the max to dislodge and remove embedded dirt. As it steps off of carpets and lands on smooth floors, will fall to about half of its maximum rating. Unsurprisingly, vacuuming carpets will drain the battery quicker.

4 Cleaning Modes

Like most robots, the N79W+ comes with the standard array of cleaning modes – auto, edge, spot, and max.

Auto-mode lets the robot roam freely across your floors until it runs out of battery. Activate this mode for general cleaning; its Adaptive Floor Sensing Technology will kick in when it transitions on and off carpets.

Edge mode forces the robot to stay close to the edges and corners of a room. However, like most robots out there, its disc shape makes it somewhat incapable of thoroughly cleaning corners and around furniture legs.

Spot mode directs the robot to travel in a spiraling motion before reaching the center of a room. This mode is great for deep-cleaning high-traffic areas like living rooms and kitchens.

Finally, on max mode, the N79W+ will disregard the Adaptive Floor Sensing Technology entirely and deliver maximum suction power on every surface it touches. This drains the battery much more quickly, reducing its runtime to about between 25 and 30 minutes.

Conclusion

The Ecovacs Deebot N79W+ is far from being the “best” robotic vacuum cleaner available. It’s not even among the top 5 models in the Deebot series in terms of suction power and convenience.

However, this doesn’t make the N79W+ a bad robot. The thing that should attract most buyers is its True HEPA Filter that traps microscopic particles and organisms with 99.97% efficiency. The Adaptive Floor Sensing Technology almost makes it an extremely versatile robot that handles both smooth and carpeted floors almost perfectly. We say almost because of the lack of smart navigation technology and dirt sensors means it’ll crawl right by accumulated piles of dirt after the first pass.

Ecovacs Deebot N79W+

As a mid-class robotic vacuum cleaner, there’s nothing more we can ask from the Deebot N79W+. It already offers a ton of convenience with its remote control, downloadable app, and Alexa and Assistant compatibility.
