The Roomba 675 vs Ecovacs Deebot n79s matchup is a comparison of two of the best budget-friendly robot vacuums out on the market. But just because they’re offered at a lower price point, that doesn’t mean they lack features or cleaning capabilities.

In this battle for which vacuum is better, let’s do a deep-dive into various features.

But if you’re in a hurry and you want to know the final verdict, the Ecovacs Deebot n79s comes out on top.

The Ecovac Deebot n79s dimensions measure up at 12” wide and 3” tall. It is about an inch slimmer and half a inch shorter than the Roomba 675. For a robot vacuum, smaller is generally better – cleaning under furniture and around tight corners is easier.

The Roomba 675 is 13.4” wide and 3.54” tall. This is a standard size for most robot vacuums in the Roomba 600 series

Weight

At 7.16 lbs, the Deebot n79s is a smidgeon heavier than the 675 which weighs 6.8lbs.

There is a handle on the top of the 675 which makes for easy transportation between different cleaning areas. The n79s does not have such a feature – this might make it a little more cumbersome to carry around for spot cleaning.

Battery and capacity

A 2600mAh lithium-ion battery powers the Deebot n79s. The battery supplies enough power for the unit to run nonstop for around 110 minutes.

The automatic docking and recharge function programs the unit to come back to its home base to recharge when the battery is running out. This ensures that the unit never runs out of battery and you won’t come home to a dead robot vacuum in the middle of a cleaning job! Note that charging time from empty to a full charge takes approximately 4 hours.

The 1800mAh lithium-ion battery on the 675 runs for around 90 minutes, notably less than the Deebot n79s. It also automatically goes back to its charging base when it senses a critically low battery.

However, some users have reported their experiences in which their 675 shuts down before reaching the charging dock, so consider that information before you make a decision. On the bright side, it takes less time than the Deebot n79s to charge from empty to full, at 2-3 hours.

You will have to start up both the 675 and the n79s manually again after recharging as these units do not start up automatically again unlike other more expensive robot vacuum models like the s9 series.

Thankfully it is a fairly simple process – there are smartphone apps for both models that you can use to control the units from wherever you are, as long as there is a Wi-Fi connection.

Filter

The Deebot n79s uses a high efficiency HEPA filter to trap airborne triggers that cause asthma or allergies, leaving you with better air quality in your home.

The Roomba 675 features Aerovac – A HEPA-style filtration system that catches 95% of dust and allergens that may be harmful to you and the people you live with in your home.

Brushes, Suction & Cleaning Technology

The Deebot n79s uses a three-stage cleaning system and claims to have 1000Pa of suction. Pa refers to atmospheric pressure and in the case of vacuums, the higher the Pa, the better the suction power.

The n79s performs exceptionally well on hardwood floors and it picks up smaller items like rice or grains more effectively due to its concentrated brushing program which kicks up less dirt and debris from the 675.

The Roomba 675 has about 600 Pa of suction power – significantly less than the Ecovacs Deebot n79s has to offer. The 675 has been reported to pick up 40-50% less dirt and debris as compared to the n79s.

This may be due to the fact that the 675’s side brushes seem to be kicking away more dirt than it sucks in due to the brush positions on the unit.

The Roomba 675 uses Dirt Detect Technology to clean around dirtier areas more thoroughly. Inbuilt acoustic sensors in the 675 detect areas of your home that are dirtier and the onboard computer programs it to concentrate more on cleaning those particular areas before moving on to the next area.

The Ecovacs n79s has a max power cleaning mode which can be activated from your smartphone through the Ecovacs Home App (available for Android and iOS). Although turning this on cuts the runtime of the vacuum by about 15-20 minutes, we feel it’s justified by the really effective intensive cleaning it does on max power mode.

1 Cool Thing: Ecovacs Deebot N79S

Navigation System

The anti-collision program built into the Deebot n79s allows it to traverse across the room or cleaning area intelligently, avoiding bumps and tripping over large items on the floor.

Areas such as ledges or stairs are avoided thanks to the inclusion of the anti-drop function, ensuring that your robot vacuum doesn’t freefall to the ground!

The Roomba also comes with cliff sensors to prevent falling down stairs.

The iAdapt 1.0 navigation system is what the 675 uses to navigate around its area. Inbuilt sensors tell the robot vacuum where to go and help it maneuver around obstacles in its path.

Compared to the Deebot n79s, the 675 has been said to bump into walls and baseboards more frequently, and with more force. This might be an issue if you don’t want to keep wiping the vacuum’s bump marks off your walls or furniture in your room.

Both the n79s and the 675 do not offer virtual mapping of your floor plan, so every time it cleans it will be a random path.

App / Phone Control

Ecovacs Home app

The Ecovacs HOME app allows you to connect to your Ecovacs Deebot n79s as long as there is a Wi-Fi connection in your home. With this app, you are able to customize the cleaning schedule for every day of the week – even if you’re not at home. The app itself is less sleek than the iRobot HOME app, but it gets the basic functions done and it is controllable via Google and Alexa as well.

The iRobot HOME app shines through in this case, with its polished and easy-to-use interface. You can customize the cleaning schedules for the Roomba 675 through your smartphone wherever you are. If you need to look through the activity history of your robot vacuum for whatever reason, you can easily do so through the app’s activity log.

Maintenance

The dustbin capacity on both the 675 and the Deebot n79s is 300ml. The bins are easily removable on either unit and it is a fairly simple process. Detach the bin, pour out its contents into the trash, and reattach it back again. They’re now ready for another round of cleaning.

 Additional Features

Unlike other robot vacuum models at a higher price point, both the 675 and the n79s are simply basic, affordable robot vacuum units that get the cleaning job done and not much else in the way of special features.

Price

The Ecovacs Deebot n79s and the Roomba 675 are both affordable budget units under $300.

The price difference between them is not that much. They’re well-priced already, so the discounts on them aren’t that large. You might save a few dollars during a sale, but you’re also losing the opportunity of automated cleaning while waiting.

Conclusion

After a long, in-depth look, the Ecovacs Deebot n79s is the winner here.
