Another notable feature in the Roomba 960, as well as 980, is the introduction of a new navigation software, iAdapt 2.0. As compared to iAdapt, this one is much more secure when it comes to evading obstacles and going from one room to the other without any hesitation. And there’s more.

The two most recent models of the Roomba 900 series present two main differences: the battery runtime and the inclusion of Carpet Boost technology.

Whereas these two models both boast iAdapt 2.0 navigation, AeroForce cleaning systems, and Wi-Fi compatibility, it is only the 980 that intelligently uses Carpet Boost on carpeted areas and rugs.

It is also this latest model that gives a maximum runtime of up to 120 minutes – that’s 45 minutes longer than the 960’s best!

Whilst both the 960 and the 980 represent iRobot’s best work to date, the 980 comes out on top once again for its superior standard features.

The Main Differences Between 600, 700, 800 and 900 Series

Whilst the basic functionality of the Roomba vacuum has remained the same, there are significant differences between the various series of machines. Here we will explore the key differences and what they mean.

The 3-stage cleaning system

If you look at the Roomba comparison chart, you will see that all iRobot vacuums utilize a 3-stage cleaning system which first loosens, then lifts, then finally suctions dirt into the robot vacuum and deposits it into a dust bin. However, different models function with different levels of air power.

600 series: These earlier series use the standard AeroVac design; it offers a healthy amount of suction and should remove dirt effectively from home floor surfaces.

700 series: The Roomba becomes more advanced with the introduction of the AeroVac 2 design in the 700 series.

800 and 900 series: It is only these series that benefit from the top functioning AeroForce cleaning system. By itself, this can offer up to 5x more air power than is available from earlier models. In the 980 however, there is also a Carpet Boost setting which uses up to 10x more air power on carpeted areas and rugs.


Most Roomba models offer some basic scheduling which can be programmed into the machine itself.

600, 700 and 800 series: The majority of models can be scheduled up to 7x per week, or can simply be told to ‘Clean’ as and when.

Selected models from 600, 800 and 900 series: The revamped 690, the 890, and the 900 series can be scheduled from the iRobot HOME app available to download to your smart device. This means that cleaning can be scheduled and activated anytime, from anywhere. The enhanced app even allows you to view a map of where has already been cleaned!

Battery Life and Runtime

Li-ion: Some models, such as the revamped 690, the 890 and the 900 series, come with Li-ion batteries. This offers greater longevity of runtime, with the maximum runtime of the 980 model advertised as a cool 120 minutes.

Ni-Mh: The advertised maximum runtime of most Ni-Mh models goes up to the 60-minute mark. However, it is taken as given that a Li-ion battery goes a long way towards extending battery life per use.

Navigation Technology

Starting from 600 series right until the 800 series, Roomba models were based on a responsive cleaning technology named as iAdapt. This technology makes use of different software as well as sensors in order to clean your home in a thorough manner. Moreover, it can also adjust itself automatically to different types of floors including carpet, hardwood as well as laminate.

The 900 series comes integrated with the iAdapt 2.0 technology as the 960 and the 980 are the first Roomba models which features a visual localization camera. With its help of this built-in camera, these models have the ability to map out your home – which isn’t possible with the previous models – for ensuring a maximum coverage.

These videos demonstrate the benefits of the iAdapt Technology

Battery Type

There are two types of batteries, which are normally used in the Roomba robot vacuums: Nickel Metal Hydride battery and Lithium-Ion battery. When the former comes integrated into a minor proportion of Roomba products, the latter is the most commonly used type of battery in these units.

This is due to the reason that as compared to Ni-MH batteries, the Li-Ion batteries sustain a longer battery life. Moreover, their durable construction makes them viable for a long-term usage.

Wi-Fi Support

This feature can be found in selected Roomba models such as 690, 890, 960 and 980 robot vacuum cleaners. A Roomba with a Wi-Fi support lets you control its operations with the help of iRobot Home App. With this application, you can not only clean your home from a long way away but at the same time, it also lets its user decide the work-schedule of the vacuum cleaner along with many other things.

Recharge and Resume

The 960 and 980 Roombas have the recharge and resume function which lets them go back to their cleaning duties after they finish recharging from the home base. In this way, even if one of these two models experience low battery during its operations, it can recharge itself before going back to its duties without any external help.

For all the other models, they have to be restarted once they recharge themselves from the home base.

Carpet Boost Mode

For making a deeper clean on different types of carpets and rugs where the dust is immersed inside the surface, the Roomba 980 is the only model which comes with the Carpet Boost Mode. Basically, this feature produces a 10 times more air power as compared to its regular operations for achieving desired results on the carpet.

Full-Bin Indicator

This feature, which is absent in the 600 series Roomba Robots, is present in every other product of this particular manufacturer. It includes Roomba 761, 770, 860, 870, 880, 890, 960 and 980 vacuum cleaners.


This is another feature which is present only in the 900 series Roomba models. It basically works with the help of iRobot Home app and once the bin gets full, you’re provided with two options. Users can either choose to finish the job with a full bin or they can also pause the robot before cleaning the bin. Once the bin is cleaned, they just have to press clean and this machine will resume its normal work.

Debris Extractor

This feature was introduced with the start of 800 series and it can now be found in every other model of the 800 as well as 900 series Roomba Products.


Criteria to Consider When Choosing iRobot Roomba Models

This section further explains the significance of the different comparison criteria detailed in the Roomba comparison chart above. This will help you to identify which features are most important to you in a Roomba and what the different models can offer you.


The weight of each Roomba machine varies from as low as 7.9 pounds in the earlier models to the highest weight of 8.7 pounds in the new 980. However, don’t be put off by this increase in weight of the machine. The extra ounces in the newer models merely belie all of the brand new exciting tech crammed into them. As the Roomba is primarily designed to be a hands-free way of vacuuming your home, the slight increase in weight should not be a big issue.


All the Roomba models, starting from 600 series right until 900 series, comes with the same height of 3.6 inches. This is basically an optimal height for a robot vacuum cleaner which allows it to glide under all kinds of furniture and sofa-sets effortlessly.

Wi-Fi Connectivity

Wi-Fi connectivity in the newer Roomba models enables compatibility with devices featuring Amazon Alexa and Google Assistant. This recent feature means that the most up-to-date Roombas can be voice activated. By delegating instructions to your Amazon Alexa or Google Assistant at home, the virtual PA device can then communicate them to Roomba in a hands-free, remote exchange.

The other perk that comes with Wi-Fi connectivity is the iRobot HOME app. This app can be downloaded to your smart device and offers you the opportunity to control your Roomba remotely. Features include the ability to amend cleaning instructions and schedules from anywhere and at any time.

In the enhanced app, you can choose for Roomba to complete one or two passes, depending on how deep a clean you want to achieve; you can view a Clean Map which displays all cleaned areas so far, and you can access iRobot tips and support. In the 980 model, even the Carpet Boost feature can be selected in-app for those extra tough areas.

iRobot Home App compatible

For added comfort, iRobot has introduced a smart app with some of their newest models. With this app, which can be installed on your smartphones and tablets, users can control their vacuum cleaners wirelessly. From giving cleaning instructions to this machine to scheduling the Roomba models to start working at a particular time, all of this can also be done while sitting a long distance away from your home.

Another advantage of the iRobot home app is the fact that it displays the cleaning status which means that you will be aware of all the areas which have been cleaned thus far by this machine. In addition, users can invoke a number of smart features, such as Carpet Boost and full bin action, with the help of this application.

Cleaning System

The 600 series Roomba models use either the first AeroVac technology or just the basic 3 stage cleaning system. These models may not have all the bells and whistles of their more recent counterparts, but they still get the job done.

The 700 series offers the AeroVac 2 cleaning system. This range offers great quality at a more affordable price. Machines equipped with AeroVac 2 still use the iRobot 3-stage system, but with less powerful air power. However, the 700 series is still a top choice for effective cleaning.

All 800 and 900 series Roombas come equipped with the AeroForce cleaning system. This is the most advanced cleaning technology currently available in the Roomba range. Utilising iRobot’s tried and tested 3-stage system, the 800 and 900 series function with up to 5x more air power than earlier models. The 980 model takes deep cleaning one step further with the new Carpet Boost option, using up to 10x more air power on carpets and rugs.

It’s worth taking into account the different surfaces the Roomba will encounter throughout your home, and consider whether it’s worth paying a little extra in order to get the added va-va-voom of the AeroForce cleaning system.

HEPA Filter

For all such customers who suffer from allergies, iRobot has introduced a HEPA Filter in some of their robot vacuums. The basic function of the high-efficiency particular air filters is to trap different kinds of pollutants and allergens in an effective way. Once trapped, these particulars will not be released back into the atmosphere which makes it a viable commodity for even the pet-owners.

Wall Barriers

All Roomba models use sensors to navigate their way through your home, maneuvering around obstacles and cleaning underneath furniture. The introduction of iRobot Wall Barriers gives you greater control over just where the Roomba can get to.

Different models of Roomba come equipped with different models of iRobot’s Wall Barriers. For further details on the differences between these accessories, please see our guide included in this article (see below). It is worth considering whether to invest in a more recent model of Roomba which comes with the updated Dual Mode Wall Barriers. These are ideal for the home where certain rooms need to be off-limits, or specific areas need to be protected.


All the Roomba robots are programmed in such a way that when their batteries run low, they run towards their home base for recharging. So you don’t have to worry about recharging these units on a consistent basis.

However, when users have to restart the previous Roomba models after recharging, iRobot has introduced a new smart feature known as Recharge and Resume in the Roomba 960 and 980. As evident from its name, these models can resume their activities automatically after recharging and they will continue to do so until their cleaning job is finished.

Carpet Boost

A feature which is limited to the Roomba 980, it basically increases the vacuum cleaner’s power by 10 times when it is performing its duties on carpets and rugs. This is due to the reason that when normal power isn’t sufficient to trap dust particles hidden inside the carpet’s surface, this feature ensures flawless cleaning without any hindrance.

As carpet boost consumes more battery than normal, it gets automatically turned off when you use the Roomba 980 on hard surfaces for decreasing battery consumption. Furthermore, you can also turn off this feature permanently through the iRobot home app settings.


As specified by iRobot, the 980 and 960 Roomba Robots come with a regular run time of 120 and 75 minutes respectively. As per the other models, the average time which they can spend on the floor, without recharging, is about 60 minutes. However, it greatly depends on the operating conditions of this robotic vacuum cleaner.

The runtime varies depending on the type of surface on which you’re going to use the Roomba models. It also depends on the mode on which you’re operating this machine. This is due to the reason that when plain floors are comparatively easy to clean, a vacuum cleaner has to exert more power while sucking dirt through carpets, rags and any other terrain involving a large amount of dirt.

Similarly, a Roomba Robot with the Carpet Boost turned on will return to its home base – for recharging – much sooner as compared to the one which is operating under regular conditions or even under spot cleaning.


Nickel Metal hydride battery and Lithium-Ion battery are the two types of batteries which are commonly used in different Roomba Models.  As compared to the Ni-MH battery, the Li-Ion battery is particularly famous for its longer battery life and fewer maintenance requirements.

Remote Control

Users can control four Roomba models, namely 690, 890, 960 and 980, remotely with the help of iRobot Home app. This application, which is available on Android and iOS, nullifies the requirement of separate remote control for directing these models.

Three Roomba Models, 761, 770 and 780, comes with a separate remote control device. However, when you can control these models with the help of this device, you cannot do such thing with your smartphone.

Multi-Room Cleaning

This is a beneficial feature for all such customers who live in big homes with several rooms. Basically, a Roomba equipped with this particular feature can easily navigate from one room to the other before making its way back to its home base for charging. As per the robot vacuum cleaners which come with this feature, they consist of Roomba 980, 960 and 880.

For Pet Owners

When it comes to handling pets and pet hair, there are a number of things which one should look for in a robot vacuum. Starting from a long battery life, it should have a powerful filter (HEPA) along with a couple of brushes (tangle free) to pick up all the pet hairs which might get trapped in the carpets. When HEPA filters make it easy to trap pollutants as well as allergens, the tangle-free brushes ensures that the pet hair, as well as fur, doesn’t get trapped inside the brush for the sake of maintenance.

There are a number of Roomba models which fits perfectly into this category, including two of the latest products: Roomba 980 and 960.

Google Assistant and Amazon Alexa compatible

Any Roomba product which can be connected with Wi-Fi is compatible with both Google Assistant and Amazon Alexa. As per the working of this particular feature, you can make your robot start, stop or even dock by simply asking either Google Assistant or Alexa to do so.

Tangle-Free Extractors

This feature, which is present in first 3 models of the Roomba 800 series, ensures a hassle-free working of this robotic vacuum cleaner. After picking up the debris, it removes hair and jams from the rest of the wastage just to make sure that they won’t get trapped in the brushes.

iAdapt improved navigation

iRobot products having this technology comes integrated with a built-in camera which makes it considerably easy to clean up your home from all kind of dirt. In addition, it also makes it easy for the robot to make its way back to charging whenever it runs short of battery.

Dirt Detect Series II

With the help of this technology, Roomba 770, 860, 870 and 880 were designed to pick up dirtier areas faster before focusing on them for ensuring a thorough cleaning.

Roomba Virtual Wall Barriers

iRobot offers a range of different Roomba Virtual Wall Barriers, compatible with their Roomba series of vacuum cleaning robots. Here we will take a look at the differences between each model, from the way they work to which Roomba model they should be used with.

Roomba Virtual Wall

The initial Virtual Wall technology originates from the 500 series of Roombas, but it works well with any subsequent series equipped with radio frequency technology. Virtual Walls are designed to be activated when the Roomba robot begins cleaning so that you don’t need to worry about turning them off or on. Simply place them in your home in order to contain the Roomba’s activity to a certain area, meaning that you have total control over where it can and can’t go.

Roomba Lighthouse

The next advancement in Virtual Wall technology is the Roomba Lighthouse. This device uses infrared signals to facilitate room to room cleaning or to create boundaries so that Roomba doesn’t venture into areas you want to keep off-limits. This means that the Roomba can be left to clean each room one at a time, completing one before it moves onto the next. Lighthouses are compatible with many models of Roomba, from select 500 series models all the way up to the 880s.

Dual Mode Virtual Wall

The Dual Mode Virtual Walls have two distinct functions: they can be used to create Virtual Walls and contain the Roomba to a certain area, or they can be set to Halo mode which keeps Roomba away from protected items. This is great if you have items such as pet bowls that need to remain in situ at all times, but you don’t want Roomba disturbing. The Virtual Wall mode on these devices has an extended range up to 10 ft. and facilitates room to room cleaning.

Authentic iRobot Parts

In order to enjoy peak performance from your Roomba with every use, some maintenance is required. Depending on the frequency with which the Roomba is used, the surfaces it is regularly working on, and the type of debris it is picking up in your home, certain parts will need replacing or changing.

It is important to always buy authentic iRobot parts. This is to ensure that the parts you are using are of a high quality and will function properly in your Roomba without compromising its efficiency.

Replenishment kits catered towards a specific series of Roomba model are easily accessible and will include everything that you need to keep your Roomba in tip-top condition.

For example, changing the HEPA filter in your Roomba every 2-3 months (depending on usage) will maintain the filter’s effectiveness at removing allergens and irritants from your home. It will keep your Roomba functioning at peak capacity, and deliver the results that you expect from a top quality product.

Other replacement items included in maintenance packs are bristle brushes, beater brushes, side brushes and brush cleaning tools. With such a well equipped and hardworking device as the Roomba vacuum cleaning robot, you must expect wear and tear over time. You should expect to have to replace components such as the brushes to maintain maximum performance, but with authentic iRobot parts, you are guaranteed good quality and longevity.

  1. I am considering a Roomba 980 because I have a dog. I noted that it employs extra power on carpet, rugs, etc. I have a very expensive Oriental silk rug in one of the rooms, and Oriental knotted wool rugs in other rooms. These are delicate rugs – would the Roomba 980 be too hard on them?

    • David Chambers

      Hi Joan,
      Speaking in general, Roomba 980 is safe for vacuuming oriental carpets. But there are some recommendations for vacuuming delicate carpets. For example, it is better to switch off the beater brush, the vacuum cleaner should have suction control and manual adjustment of the beater’s height. It is also desirable to use side-to-side movement and not to vacuum fringe etc. Robot vacuums are not designed to fully comply with these recommendations. Therefore, if you have expensive delicate carpets it may be best to vacuum them with upright or canister vacuum cleaner.
