Ecovacs DEEBOT N79s Review – Cleaning

The DEEBOT N79s uses a Double V-style roller brush that agitates dirt and flings debris toward its suction tube.

Notice in the image below shows how the V shape creates a sort of “concentration point” for this sweeping motion.

Double V Brush

Vacuum performance is pretty good but can be a bit inconsistent.

For what’s considered a budget robot vacuum it cleans about as well as others in this price range.

Although its suction strength is on par with most robot vacuums, at around 1000 Pa or Pascal Units, the noise level isn’t overwhelming at all.

The ECOVACS DEEBOT N79s also has twin spinning side brushes that grab dirt and pet hair gathered along walls. They fling particles toward the roller brush where it gets sucked into the dustbin.

The DEEBOT N79s is not recommended for high or dark carpets.

  • High carpets tend to slow the robot vacuum down.
  • While dark carpets can confuse the infrared sensors.

Since dark colors absorb light, it weakens the signal that’s bouncing back to the sensor.

The causes the robot to lose accuracy.

The dust bin is a little smaller than average at 450 ml (15 ounces). Emptying it will be a regular duty, especially when a lot of pet hair is around.

It also uses an air filtration system that combines both a sponge filter and high efficiency filter.

Together they do a great job at trapping finer particles and preventing them from circulating back into the air.

Other specs on the Ecovacs DEEBOT N79s include:

  • Run time of up to 100 minutes on a single charge.
  • Weighs 6.7 lbs
  • Has a height of 3.1 inches

Maintenance is pretty simple. Buttons release the brush cover and side brushes and the included tool can be used for removing tangles.

Ecovacs DEEBOT N79s Review – Navigation

Using what ECOVACS calls Smart Motion Navigation, the DEEBOT N79s is excellent at avoiding obstacles.

Although it looks like seemingly random patterns, the DEEBOT does have some method to its cleaning madness.

It uses a combination of these sensors to navigate around rooms.

1. Drop Sensors – measures floor to device distances

2. Proximity Sensors – measures obstacle (walls) to device distances

3. Bump Sensors – measures bumps into said obstacles

You won’t need to worry about the little guy tumbling down steps, although it might sneak outside if you leave the front door open.

You might even feel a little sorry when it starts beeping for you to come to its rescue when it actually does get stuck.

There’s also an AUTO button on top and a power button on the side for manual control or quick starts.

Cleaning Modes

The Ecovacs DEEBOT N79S has four cleaning modes that are controllable with the remote as well as the DEEBOT app:

Auto, Spot, Single Room and Edge

Deebot N79s Cleaning Modes

For a brief summary of what each of these modes do check out our Robot Vacuum Basics page.

The random paths it takes around floors in Auto mode does make it slower and less efficient than higher priced robot vacuums like the Neato Botvac D7.

In larger rooms or open floor plans it might even run through the battery charge without hitting every spot.

The DEEBOT N79S will then return safely home to take a few hours and recharge.

Ecovacs App

The remote control has a nice size LCD screen. You can easily set a cleaning schedule and choose cleaning modes.

Scheduling a cleaning is about as much fun as figuring out how to change the time on your car stereo.

The interface of the DEEBOT app is just much more user friendly.

Wi-Fi Control

What separates the Ecovacs DEEBOT  N79s apart from similar robot vacuums in the same price range certainly isn’t the performance.

The navigation is great.

But as we previously mentioned, its vacuuming is about the same as other models in this price range.

The DEEBOT N79s popularity can really only be explained by having smartphone control at a budget friendly price.

In fact it’s around $100 less that the next Wi-Fi connected robot vacuum.

Some features of the app include:

  • Choosing cleaning modes
  • Manually controlling the device
  • Setting schedules
  • Viewing notifications like battery power
  • Receiving alerts

Developers are always fine tuning apps and this one keeps getting better with time.

Ecovacs DEEBOT N79s Review Summary

Our main takeaways for the DEEBOT N79s are this:

  • It performs about as well as similar priced robot vacuums when it comes to general vacuuming.
  • The addition of smart phone and Alexa voice control at this price really puts it over the top as a great value
  • It’s built for average-size homes with low pile carpet and bare floors.

The amount of dust in your air that it reduces alone is well worth the price tag, especially for those family members who are prone to allergens and asthma.
