Main differences

In the beginning, we would like to address, that both vacuums are actually very decent units. What’s more, we are convinced, that either one of those should be satisfying for most of the consumers. There are, however, few things to keep in mind before you make the final decision.

The first major difference is the implemented motor. Since each vacuum runs on a different motor, the suction also completely differs. The Roomba 890 boasts 1000 Pa suction, while the Roomba 675 has only 600 Pa suction. This makes the 890 models, significantly more powerful, and therefore, better at removing the deeply embedded dirt and debris.

Another big dissimilarity is the dustbin capacity. The Roomba 890 can hold up to 620 milliliters (~ 21 oz.) of dust and debris while the Roomba 675 has only 350 milliliters (~ 11.8 oz.) of capacity. This can be especially important in big households, where the unit has a large area to cover. Since you don’t want to constantly empty the dustbin, it’s something to keep in mind.

The next crucial difference is the noise level. The whole point of robotic vacuums is to free up your time. Therefore, the units shouldn’t be too loud when you are doing other activities. The noise level is different in both vacuums, probably due to them running on different motors. The Roomba 890 produces around 68 dB while the Roomba 675 produces only around 62 dB.

There are also smaller differences, such as the weight or the filtration system. The weight won’t be too significant, as you won’t operate this unit manually anyway. Nonetheless, the Roomba 675 weighs 6.77 lb. while the Roomba 890 weighs 8.4 lb., so it’s noticeably heavier.

The filtration system differs, as the Roomba 675 has “AeroVac” filtration, and the Roomba 890 has “AeroForce” filtration implemented. Although we have to say, we didn’t find see any difference in the air quality. In our opinion, both vacuums do good when it comes to pulling out the dust and other small particles from the air.

Those are pretty much all the crucial differences, that you should know about. Based on those factors, you can already choose the best option for your household. However, we strongly recommend reading the rest of the article, to learn all the important details.

Cleaning performance

The cleaning performance is one of the most important aspects when it comes to choosing your new cleaning device. By this, we mean how well a particular unit does, compared to other products from a similar price range. 

In the beginning, we have to say, that both robotic vacuums do a pretty good job at removing dust and debris from hardwood floors. We didn’t find any major issues with the brushes getting stuck or not completing the cleaning process.

This can be due to the implemented technology – Both vacuums utilize 3 stage cleaning system, that boasts auto-adjusting cleaning head and high-efficiency filters. The cleaning head chooses the most optimal height for the vacuum, so the brushes have constant contact with the cleaned surface. What’s more, the rubber brushes are made in a way, to prevent tangling around pet hair.

All the dust, pollen, or other particles from the air are removed with high-efficiency filters. Those can be easily replaced if needed, by going to the official manufacturer’s website or finding the proper listing on Amazon.

There is a difference in the power of each vacuum, as they both run on different motors. The Roomba 890 can produce the maximum suction of approximately 1000 Pa, which will do a significantly better job at removing dirt or other debris, than the Roomba 675 with only 600 Pa suction.

Both units also have the same “iAdapt 1.0” navigation system, which allows for very efficient cleaning. There is no difference to the included features, as they highly rely on the navigation system, some of those are virtual walls – they allow you to keep your Roomba out of a certain location, scheduled cleaning – allows you to set a time, at which Roomba starts cleaning. 

The virtual walls can be set up with the virtual wall barrier, that comes with the product. It’s a small tower, that can be placed in a spot, that you don’t want Roomba to enter.

The vacuums will also suggest you some cleaning recommendations, based on your cleaning habits. This and much more can be done using only your phone and special iRobot home App. Operating each of the units can be done using your phone and Google Assistant or Amazon Alexa.

When either one of the vacuums runs out of battery, there is an “auto-recharge” function. It allows them to go back to their cleaning station, recharge, and continue cleaning.

There is no mapping included in this navigation system, therefore you can’t schedule cleaning by the room or make virtual walls from your app. However, there are a few more features, that you may find very convenient.

Each of the vacuums also boasts a large number of sensors. Those prevent the units from dropping down the stairs or hitting walls and furniture. Those are rather common in most of the robotic vacuums, however, those two Roombas also boast dirt detecting sensors.

When the vacuum detects a large amount of dirt or debris under itself, it focuses on this area, increasing the suction at the same time.

Those are pretty much all the important aspects of the cleaning performance. Of course, there are many factors that affect the performance indirectly. However, we will talk about those in the latter part of the article.


The capacity is another important aspect, as it’s the second most important limiting factor when it comes to the maximum cleaning time, right next to the battery life. This can be important for people with large households, as you don’t want to constantly replace the dustbin.

Fortunately, both vacuums also have a pretty decent capacity. Although we have to admit, the Roomba 890 is significantly better in this aspect. It boasts 620 ml. which translates to around 21 oz. while the Roomba 675 has only 350 ml. dustbin capacity, and it translates to around 11.8 oz.

Each one of the vacuums from this article should suffice in most scenarios. However, remember to constantly replace the dustbin to prevent any damage or performance reduction.

Noise level

The noise level is an aspect, that isn’t important in most upright vacuums. However, in robotic ones, the situation is completely different. Since those were made to free up your time for other activities, you don’t want to be bothered by an extra loud vacuum running in the background.

We also often see, that many people don’t actually realize how loud robotic vacuums can be. Many customers think that those produce little to no noise when in reality, some of them can be as loud as standard upright vacuums. Fortunately, the ones coming from reputable companies, usually keep the noise at low levels.  

The Roomba 675 is a winner when it comes to the noise level, as it produces only 62 dB while the Roomba 890 produces approximately 68 dB. The difference isn’t huge, however, it’s worth mentioning. Both of those noise levels can be compared to the sound of a normal conversation.

Remote control features

The manufacturers often implement multiple remote control features for extra convenience. In the case of the iRobot Roomba, this is highly dependable on the series, as all of them have different specifications. The ones in this article come with the most necessary remote control features.

Both Roomba 890 and Roomba 675 can be operated using your smartphone with a special iRobot home App, as well as using voice commands. To do this, you have to integrate the vacuum with Amazon Alexa or Google Assistant.

Battery life

The battery life is the main limiting factor when it comes to the maximum cleaning time. Even though most of today’s robotic vacuums boast an auto-recharge function, it’s always a good idea to invest in more runtime.

The Roomba 890 can clean for a maximum of 90 minutes which is exactly the same as the Roomba 675. The manufacturer managed to keep the runtime at an above-average level, despite the boost in the power. One thing to remember is that the maximum cleaning time may differ based on the cleaned surface.


The design is also an important step in creating an efficient robotic vacuum. In order to fit under and around most of the furniture, the unit has to keep a low profile and slim design. Fortunately, the iRobot has plenty of experience in this field, so it wasn’t a big problem for this company.

If you would like to learn more technical information, the Roomba 890 measures 13 x 13 x 3.6 in. and weighs 8.4 lb., while the Roomba 675 measures 13.4 x 13.4 x 3.54 in. and weighs 6.77 lb. As you can see, the Roomba 890 is significantly heavier, although it shouldn’t cause a lot of trouble.


The price is often the first thing you check when you compare different robotic vacuums. Therefore, many people already know the price difference between the two units, however, we still decided to mention it in this section.

The Roomba 890 can be found on Amazon for the price of $499.00 (Click here to see the price!), while the Roomba 675 can be found on Amazon for the price of $279.99 (Click here to see the price!). Although, you should know, that the price can fluctuate quite a bit. Therefore, we highly recommend checking the prices before making the final decision.

Necessary maintenance

The necessary maintenance is another crucial aspect, however, it’s often skipped by people who are new to robotic vacuums. This is very unfortunate, as, in order to keep your new robotic vacuum operating at the desired level and to prevent permanent damage, you should always take proper maintenance steps. 

We won’t get into details, as it would simply make the whole article too long. However, we will try to give you a few basic maintenance tips, that should work for most of the robotic vacuums.

In order to keep your Roomba operating at the desired level, you should:

  • Regularly clean/rinse all the brushes
  • Regularly check the brush roll and side brushes for any stuck dirt and/or debris
  • At least once a week clean the cover of the vacuum/wheels
  • Replace any used or damaged elements as fast as possible
  • Regularly empty and check the Roomba’s dustbin for any stuck dirt or debris

Those are only a few of the most important maintenance steps, therefore we highly recommend reading the user’s guide. You can find there all the crucial information.


In conclusion, both robotic vacuums are very efficient units, that should suffice in most scenarios. What’s more, we are convinced, that most of the customers should be content with either one of those. However, there are few things to keep in mind before you make the final decision.

Some of the most important differences are the suction (Roomba 890 has almost twice the suction of the Roomba 675), capacity (Roomba 890 has, once again, almost twice the capacity of the Roomba 675), and noise level (Roomba 890 produces 68 dB while Roomba 675 produces 62 dB). There are also a few smaller differences, such as the filtration system or overall weight.

We would say, that the Roomba 890 is a winner of this comparison. It’s a great overall vacuum, that can be interpreted as a new, refreshed version of the old Roomba 675. There are improvements in almost every aspect, that are worth the extra money in the end.

We hope, that after reading this article, you will be satisfied with the final decision.
