If you’re tired of having to empty the dust cup of your robot, this is the solution you’ve been looking for.


The s9+ can empty its own dust cup. In fact, it will do that every time it goes to dock. We’ll tell you more about it later.

If you’re on a budget, you can still get some premium features from the 980 model. Depending on your needs, the bells and whistles of the s9+ might not suit you anyway.
One obvious upgrade the s9+ has over the 980 is power. It houses a new and improved motor which boosted its suction. 
The s9+ is not round like its predecessors and this helps it cover more floor space and hence, clean faster. 
Edges and corners have always been an issue with round robots. The D-shape helps the s9 reach deeper into corners and clean edges better.

Common Features – Roomba s9+ vs 980

As you can expect, products from the same brand and in the same line will definitely have some things in common.

You can feel good about this as it means you will get some of the s9 features while paying less for the 980.


Navigation and Sensors

Both the Roomba s9 and 980 use the same iAdapt and vSLAM technology that are exclusive to iRobot. These are what let them scan, map, and plan their movement.

roomba 980They also move in a serpentine pattern and complete their route with a perimeter run. This pattern of movement ensures that both robots will efficiently clean your floors without leaving patches.

However, the Roomba s9 shows it costs much more with its Imprint Smart Mapping.

This piece of tech helps the s9 learn and adapt to your floors. The more it roams, the better it knows your home and the better it navigates.

Another extra this technology brings is that it allows the s9 map and store up to 10 different floor plans! This is quite useful for those who have multiple floors in their homes.

iRobot claims that if you take this robot to another home to clean, when you bring it back to yours, it will still clean like it never left. Now that’s some awesome tech, right?


Smart App

Almost every robot vacuum worth having nowadays use a dedicated app. Of course, these two are not left out.

Firstly, you need to get the app on your phone. Once done, you can monitor and control either Roombas from wherever you are.

Secondly, the app allows you to schedule the robot to clean at certain times. For instance, you can have it clean at night when you go to sleep or when you go out.

Furthermore, you can switch from one mode to another from your smartphone depending on the type of vacuuming you need at the time.

The s9+ goes further. With the Smart mapping we spoke of earlier, you can label each room on your floor and have the robot clean any independently.

The app is pretty straightforward to install and pair for both robots as long as you use a strong enough Wi-Fi connectivity.

With the app, you can experience the true autonomy of robot vacuums.


Smart Home Integration

In this day and age, having your home appliance do stuff by itself is getting popular. Devices can now be interconnected and centrally controlled.

If your home is on this level, either of these robots can easily blend in with your array of interconnected devices.

They are both compatible with Google Assistant and Amazon Alexa. With those, you can issue voice commands and have the robot obey verbal instructions.


Virtual Wall Barrier

There are times when you don’t want your robot vacuum to go to a particular area in your home.

These Roombas have a device that creates virtual barriers that will prevent the robots from going beyond where you set it. To the vacuum, the virtual barrier is a wall and it will turn back on getting to it.

The device work in two modes. You can use one to create a straight line while the other can create a circular barrier around itself and an object. There’s a switch beside the device to toggle between the two modes.

Both Roombas come with a pair of this device. However, if you need more, you can purchase them separately.


High-Efficiency Filter

This is an important feature to consider if you are allergic or asthmatic. These robots use filters that are good enough to protect you from inhaling airborne contaminants.

They are efficient enough to trap more than 99% of allergens and dust, preventing them from getting back into your home.

The s9+ goes an extra mile with its filtration system. Its filter is made from a material that is capable of trapping dust mite, pollen, and mold allergens.

As for the 980, its filter can trap 99.97% of particles in the air that pass through it down to 10 microns. That is highly efficient considering the diameter of a human hair is 50 microns.

So, whichever of these robots you go for, you can rest assured you’re getting a good filter.


Recharge and Resume

All robot vacuums can find their way back to their docking station, at least in theory.

Different circumstances can cause a robot to lose its way, though.

However, these two will always locate home. As long as you follow the instruction manual on how to position the charging dock.

If either of these robot vacuums could not finish their rounds before their battery runs low, they go back to dock and recharge.

When they’re done recharging, they will find their way back to where they stopped and continue.

This is an awesome feature especially for those who will schedule the robots to work while they are not around. That way, they won’t come back home to a half-cleaned floor because the robot had to recharge.


Dual Rubberized Brush Roll

Both robots use a double brush roll located underneath it. If you’ve been using vacuums for a while, you will know that brush rolls can become a hassle when they are often used to clean hairs.

The s9 uses the same brush roll design as other Roombas since after the 690, however, the location is now different because of its shape. The brush rolls are also longer.

Cleaning off tangles of hair afterward is something most people don’t like doing. So, you won’t be doing much of it with these two.

The brush rolls on these Roombas do not have bristles. Instead of bristles, there are ridges on the brush rolls to comb through carpets instead.

The result simply is a good clean of pet hairs without tangles to deal with afterward.


Dirt Detection

This feature has been on Roombas since the 600 series. It is great for Roomba’s cleaning capacity.

What this piece of technology does is to help the robot identify a concentration of dirt on the floor.

Once identified, the robot will make extra effort to get the place sufficiently clean by spending more time there.

This is a great feature to have if you have highly trafficked floor areas in your home. This feature also triggers when you use either robot in the spot clean mode.


Impressive Runtime

Battery life is often an important factor to look out for when choosing a vacuum that runs on battery. No one wants a vacuum that will clean only one room and needs to recharge for hours.

Both the Roomba s9+ and the 980 have 120 minutes to do their thing. This is great as they will at least complete most of their chores before needing to recharge.

Their runtime can be attributed to their coordinated cleaning pattern which is quite efficient with respect to performance and time.

Unique Features – Roomba s9+ vs 980

Features Unique To s9+

Roomba Clean Base

We have seen many innovations in robot vacuums over the years. A self-emptying dust cup is one that took us by surprise. This is something people have only been imagining and iRobot has brought it to life.

The Roomba s9+ can empty its dust cup automatically several times before you need to intervene. We should let you know that there is also the Roomba s9. The only way it is different from the s9+ is that it does not have this clean base.

Now, let’s tell you how it works.

The process

The docking station is obviously larger than usual. This is because it is not only a docking station, it is also a dust cup emptying station.

Whenever the robot goes out to vacuum, it gathers dirt in its dust cup. Every time it comes back to dock, it dumps the contents in its dust cup.

There is a mechanism in the contraption that sucks dirt out of the Roomba into a bag inside the ‘tower’. So, every time the robot goes out to vacuum, it is doing so with an empty dust cup.

iRobot claims that the collection bag in the ‘tower’ can hold up to 30 dust cups of dirt!

Now let’s do the math, the Roomba s9+ has a dust cup capacity of 0.2 liters. If we multiply that by 30, that amounts to 6 liters.

Unless your home is constantly dirty, we don’t see how you will fill that up any time soon. 30 is a big number in this case, we are talking about weeks here.

If you don’t have pets or kids, maybe even months before you need to change the bag.

This feature is fantastic on different levels. One of which is the fact that you won’t be babysitting this one at all.

Secondly, you can have more confidence to schedule the robot as you won’t need to bother about emptying. Not anymore will your robot stop work halfway because of a filled dust cup.



This is an entirely new concept from iRobot, though it isn’t new in the industry. The entire line of Neato’s robot vacuums is all D-Shaped.

This shape gives the s9+ added advantage to clean edges and corners better than round robots. It also makes the brush roll longer as it is now located at the flat end for wider and more efficient coverage.

The size is quite compact which makes it easy for the robot to maneuver around furniture and obstacles.



The s9­­+ now occupies the space of one of the most powerful robot vacuum cleaners with its 22 cfm of suction. The suction of the 980 is nowhere near this.

This is one of the reasons this robot broke records in our deep cleaning test. Firstly, it achieved a 94% efficiency in deep cleaning tests.

Secondly, it picked up most of the dirt in ½, ¼, and 1/8 crevices. This goes to show that the Roomba s9 is not just powerful, it combines efficiency with it.

Features Unique To Roomba 980

Round Shape

Just like every other Roomba before it and a few after, this one is a circular robot. There isn’t anything wrong with this shape but it has difficulties cleaning into corners.

It only makes sense since its all curves. Even with the side brushes, it still does not do a great job with corners.
