The Ecovacs Deebot N79S

Ecovacs Deebot N79S is one of the best on the market in its price range so far

The Ecovacs Deebot N79S is one of the best-selling robot vacuum cleaners on Amazon and owners love it. Its strong suction can pick up pet hair, dust, and dirt from thin carpets and bare floors. Its dustbin gets full after every cleaning session, making it perfect for pet owners. As we said before, the Ecovacs Deebot N79S is integrated with Amazon Alexa and can be controlled by voice as well as via the app and IT remote control. The two side brushes catch and transfer dust and dirt to the dustbin. Besides, the robot has a helix main brush and high-efficiency vacuum suction that work together to make your floors clean. Unlike its older brother, the Ecovacs Deebot N79, the N79S has Max Mode Suction that provides deeper cleaning.

What is not that good about the Ecovacs Deebot N79S?

Hair gets tangled around the main brush which happens with all robots equipped with the bristle type. The ECOVACS app requires 2.4G Hz Wi-Fi. Please make sure you set an additional channel on your router at this speed.

You probably will not find another robot vacuum cleaner that costs $200 that would be compatible with Alexa. Considering its performance on thin carpets and the way it handles pet hair, the Ecovacs Deebot N79S is one of the best on the market in its price range so far.

What is the ECOVACS Deebot N79S good at?

  • One of the best robots considering its price and performance
  • Compatible with both: Amazon Alexa and Google Home
  • Has a remote control for those who don't want to manage it by the app
  • Supports Wi-Fi which means you can control it with the ECOVACS app
  • Performs excellently on bare floors and thin carpets
  • Affordable price tag
  • Max Mode increases your cleaning power by 2x.

The Shark Ion 750

Shark Ion 750 is a budget robot vacuum cleaner that supports Alexa

The Shark’s brush roll has a slightly different design that requires less maintenance and doesn’t get hair tangled in it as easy as the Deebot does. The Shark Ion 750 is lower than the Ecovacs. In the box, you will find magnetic tapes for blocking the robot from places it should not go. The robot is excellent at picking up pet hair. The machine smoothly goes over a medium carpet and crosses a threshold. Same as the Ecovacs Deebot N79S, the Shark Ion 750 is integrated with Amazon Alexa/Google Assistant. Based on consumer reviews, the Shark Ion performs better on medium carpets than the Ecovacs Deebot N79S.

Issues with the Shark Ion 750

It took a few attempts to connect to the app. It also often loses connectivity to Wi-Fi. It has a basic app, but we hope the manufacturer will fix it soon. The anti-tangle brush still gets hair wrapped around it sometimes, but based on consumer reviews, it happens less often than with other robots.

Overall, the Shark Ion is a powerful robot able to make your floors clean. It is compatible with Alexa and costs about $300, which is a good deal considering its features.

What is the Shark Ion 750 good at?

  • Supports Amazon Alexa/Google Home
  • Has the brush design that prevents hair tangling
  • Easy-Empty Dust Bin that is easy to get from the side of the robot
  • Can be controlled by the app
  • Can do both: bare floors and thin carpets. Even some of the medium-pile carpets too
  • Low body can reach areas other vacuums can't reach
  • Magnetic stripe keeps the robot from places it shouldn't go.

The Eufy RoboVac 11+

Eufy RoboVac 11+ one of the best budget robot vacuum cleaners in 2018

The Eufy RoboVac 11+ is also one of the best-selling and most highly-rated products on Amazon. Along with two side brushes that sweep dust and dirt from corners, it has a bristle cleaning brush that scratches thin carpets and transfers all the dust and pets hair to its dust box. A motor delivers 1000Pa of suction power, enough to leave thin carpets and hardwood floors clean. A new feature, BoostIQ Technology, automatically increases suction power when extra vacuuming strength is needed. Since the Eufy doesn't support Wi-Fi, it can be managed by its IR remote control. Anti-scratch tempered glass protects your furniture from damage.

What is the downside of the Eufy RoboVac 11+?

This robot is mostly designed for hard floors and a few area rugs; it is not suitable for thick carpets. When it runs on carpeted surfaces, its battery lasts slightly over an hour.

For the price of around $249.00, the Eufy RoboVac 11+ is an fantastic and decent robot that will suit your needs.

What is the Eufy RoboVac 11+ good at?

  • A large dustbin holds more dirt which decreases the needs of emptying too often
  • BoostIQ Technology automatically increases suction power when extra vacuuming strength is needed to get the best clean
  • Performs well at bare floors and thin carpets.


It is easy to find replacement parts for the Eufy RoboVac 11+ and the Ecovacs Deepbot N79S on Amazon. If you need a new filter, or a side/cleaning brush, you can always find it on sale.

The Shark Ion is a different matter. So far, you can only get extra accessories directly from the Shark website, which would probably not be that good for most consumers.

Worth to mention that you can use all the extras coming in the box for about six months at least.

Which one should you buy?

Cleaning performance is about the same especially when it comes to a hardwood floor, tile, vinyl, etc. Neither can clean thick carpets, but thin rugs are no problem for all of them. All of them have strong suction that can pick up pet hair and the smallest particles from bare floors. Be ready to empty the dustbin after every cleaning session since it gets full every time (especially the Shark Ion 750 because it has the smallest one). All the machines get stuck and need to be rescued from time to time.

The Shark Ion 750 seems to be the lowest (note that the manufacturer specifies its height without the wheels), so it will probably fit under most of your furniture. The height difference between the three is not that much.

Since neither of the robots has mapping and smart navigation, they move randomly over the cleaning area. The robot doesn't remember where it's been; only "mapping" machines can do that.

The Ecovacs Deebot N79S is the cheapest robot vacuum that is integrated with Amazon Alexa and Google Home. It is ideal for small and medium-size homes with bare floors and some thin rugs. Plus there are no issues with buying additional accessories on Amazon.

The Shark Ion and the Ecovacs Deebot N79S are Wi-Fi enabled and come with an app. Consumers claim they are having troubles connecting the Shark to Wi-Fi which hasn't happened with the Ecovacs. This issue causes difficulties with Alexa and compatibility becomes worthless without Wi-Fi.

Within all three robots, only the Shark Ion comes with magnetic tapes that are supposed to block off areas.

The Eufy RoboVac 11+ works the quietest. It will not disturb you nor your family while operating. The Eufy is the only device here that doesn't have an app and does not support Wi-Fi. You still can manage it through the remote control or manually by pressing the "Start" button on the lid.

All the robots are equipped with sensors that prevent them from falling from stairs and help them avoid obstacles on the way. Plus, they have the auto-recharge feature.

It is hard for us to make a conclusion which one is better. All three robots are amazing, have decent battery life, exhibit good cleaning performance, etc. It depends on your preferences and what you need a robot cleaner to do. Which one would you get for yourself? Leave a comment down below.
