Review of the Ecovacs Deebot N79 Robotic Vacuum

tldr; The Ecovacs Deebot N79 is a worthy robotic vacuum that may not be as smart as some of its competitors but it definitely has a great feature set and does an excellent job of its primary job–it is a really good vacuum.

My daughter asked for a robotic vacuum cleaner for her 9th birthday. (Looking for better gift ideas for a gifted and talented student? [Opens in a new window]) A strange request, but my wife and I were talking about getting one anyway, and the birthday wish was the push we needed to finally look into it and make a decision as to which robot vacuum to purchase. There are several competitors, and among the competitors there are different price points and features. It was difficult to decide.

We mainly considered the Roomba  and  Ecobots offerings. They seemed to get the most favorable reviews. We were especially interested in the Roomba model that Costco sells (Not a member of Costco? See my review!), but since we weren’t really sure how much use we’d get out of it, we didn’t want to shell out nearly $400 for it. So we decided to look for something cheaper.

As we looked at the various models, we considered whether they would be able to interoperate with our Google Home, whether they had the ability to mop the floor as well as vacuum, and how well other reviewers received the devices. We eventually settled on the Ecobots N79 and purchased it from Amazon. We loved the fact that former Roomba owners endorsed it, and were sold when we read the review from the woman who left  her sliding glass door open and found it outside dutifully cleaning her patio until it got stuck in some lava rocks.

The Deebot N79 was easy to setup and get it going. It comes with a charging station and a tool used to clear hair, etc, from its rotating brush and to clean off the filter intake. The first time we ran it, we were extremely impressed, if not a bit mortified by the amount of cat hair and crud it picked up before heading back to it’s charging station about an hour later.  We don’t keep the tidiest house, but we do vacuum and we didn’t think there would be so much invisible debris. It didn’t stop there though. It’s holding tank was stuffed full the next few times we ran it–I am sure it sucked up an entire cat’s worth of cat hair…and much more. To be fair to us, the robot is able to slip under our sofas and is rather persistent about trying to get into various corners we may often miss.

Certainly, one of the things we like about this model is that it has a low profile so it can get under the sofas.  It also can slip between our dining room chairs which means it does a decent job of cleaning up after dinner. It has side-brushes that stick out and sweep crumbs into its rotating brush path (also a distinguishing feature as many of the competing units don’t use a spinning brush). We also like the fact that it can be programmed to start automatically at a certain time of day either via the included remote control or from a free Android/iOS app which can trigger a vacuuming from anywhere you have an internet connection.

The Deebot N79 seems to be very durable and determined to do it’s job. I really like the fact that it is really easy to change and clean it’s brushes. Even the main roller brush has a compartment that easily snaps open, so it makes it easy to clean off hair that gets wrapped around it etc (and they also include a tool that helps you cut off hair without taking out the brush too. Also, it is no problem to change its air filter–again you just snap open a chamber on the dirt collection box and you can just put in a new one.

The Ecovacs app includes a timer that tells you when to officially change certain parts (like the side brushes or the air filter). The box we got came with 2 extra side brushes and an extra air filter. And when you need additional parts for the vacuum they are readily available on Amazon, and aren’t that expensive.

As you can tell I am genuinely happy with our purchase, however everything isn’t perfect about the vacuum. Unlike some of its competitors this device is rather dumb. It runs in random patterns and redirects itself if it approaches something it can “see” in its path such as something tall like a wall, sofa leg, a person or the top of a staircase. It doesn’t always see things ahead of time but if it runs into something it is a relatively harmless bump that turns it around and sends it in another direction.

While some of it’s more expensive competitors can map your house and know which areas it has done recently, this one is clueless. Still, in an average session, it seems to find its way all over the place. So even though it doesn’t have all the smarts, its cleaning algorithm seems to get it around to enough places so that it is still effective. It handily gets between our hard wood floors, our area rugs, and the shag carpet in our bedrooms–this is something that apparently can’t be said of certain competing robotic vacuums.

This review would be remiss if I didn’t include a sort of warning for new owners. You kind of have to “clean up” for this robot if you want to get the most out of it and/or don’t want to risk certain belongings getting chewed up by it. We’ve had two occasions so far where this became an issue. One time it made it’s way into our bedroom and found a dress that was touching the floor in the closet. It did manage to suck it into it’s brush and apparently tried to get away with it. It didn’t end very well for the dress. The vacuum’s consumable side brush got a bit torn up in that tif as well.

Another time our indoor welcome mat got sucked in and dragged around until the robot stopped and shut itself down. This probably wouldn’t have happened, but our mat had become a bit disheveled. The point is that you have to get certain things out of the robot’s way or it is going to try to “neutralize” it. So before you decide to buy one of these, look around your house and think about what may need to be picked up before vacuuming. If you have chairs whose legs are too close together, that could also be something you’d have to move out of its way if you’d like it to clean in that area.

This should be obvious, but the robot can’t go down stairs by itself. So if you have a multi-level dwelling, you will need to physically move the robot yourself and turn it loose. It won’t be able to find its way back to the charger if you do this, so it will eventually just die someplace and let out a sad beep to make you aware of its failure. Certainly it is worth the effort to move it to another level for a while and let it do its thing while getting a break from the usual scenery.

There is another odd foible about this vacuum that I would like to mention. You can use the app to schedule vacuum sessions ahead of time at different times of day/days of the week, etc. It isn’t that much work, but in an instant, your schedule can potentially disappear. If for some reason you decide to use the robotic vacuum’s On/Off switch to toggle the power–something that there is rarely a valid reason to need to do–your schedule will be toast. That makes absolutely no sense and I hope they will fix the problem at some point.

It seems to me that if the app in your phone knows what the schedule was, it could easily re-download it to the vacuum’s memory at next opportunity. But for now, if you toggle the power on the vacuum, and return to the app, your schedule will also be removed from there…and you’ll have to recreate it. Rather a pain.

In spite of that and the above detractors, I definitely do recommend this vacuum. At the price, you probably won’t have an easy time finding something that is as reliable and capable. Don’t take my word for it, you’ll definitely want to have a read over the other reviews on Amazon.
