Roomba 620 vs 650

When it comes to iRobot, you can certainly say that the Roomba 60 is one of the most successful series so far. Every model that has been released on the market so far has gained countless of satisfied customers – among them being the Roomba 620 and 650 models.

The Breakdown

Both models came at different times – and while they may have their similarities, they also have their differences. If you are struggling to choose the better model for your household, here is a comparison of Roomba 620 vs 650 that will make your choice easier.


When it comes to setup, both Roomba 620 and 650 are quite easy to set up. The process is fairly intuitive – and even a novice that has never used such a device should be able to do it.

Both models arrive with a setup manual which you can use if you are a complete beginner. And if you are totally at a loss, you can even contact the support team from the product website.


At 17 x 18 x 5 inches and weighing almost 8 pounds (7.9, to be more precise), the Roomba 620 is perhaps one of the most originally designed robot vacuums that you can buy. Its relatively large frame allows covering a wider surface – cutting the cleaning short. It also allows for more dirt to be gathered.

Most Roomba units come in a black design; however, this unit has a unique black and white color pattern that makes it stand out. The design, at the same time, is fairly minimalistic – meaning that it won’t be unsightly even if you “let it loose” when guests are coming. It also gives off a sleek golden glow, which is very pleasant to look at Its buttons are also very easy to navigate – mostly because you only have three buttons that you have to command. It is so well-designed that you may actually not even need the manual. It is small enough – and it will certainly fit under almost any type of furniture – even those places that are relatively hard to reach.

At 13.4 x 13.4 x 3.6, the Roomba 650 is a bit smaller compared to the 620 – and also looking relatively different. Featuring a sleek, minimalistic design in a jet-black color, this could just as well be an ornament as it is a vacuum cleaner. It also weighs as much as the 620, even though the unit is much smaller.

Thanks to its compact design, this unit can fit into even tighter places – even the trickiest corners that are left unvacuumed. It also features the same ease of use as the 620, with only a few buttons to command.

Compared to other Roomba models, such as those in the 900 series, these two models are relatively low-priced – which is why we need to ensure that both vacuum cleaners can do a very good job. If not, we ought to at least find out which one is better.

While the Roomba 620 is far from perfect, it can still deliver a very satisfactory job. It can finish off some of the most boring tasks, giving you the time necessary to actually do the things that you like.

That being said, while its suction power is fairly good, its navigational system is sometimes not so stellar. This robot cleans pretty much at random – and while it does feature a Dirt Detector, there is the possibility that some places might be left untouched. As a result, the Roomba 620 might be in constant need of a babysitter.

On the other hand, you can say that the 650 is more high-tech. Not only can you schedule it up to 7 times per week, but it can also automatically dock and recharge. It’s a unit that begins to clean on its own – and moreover, goes to recharge on its own. What more can an owner ask for?

The drawback in performance is that, just like the 620, the 650 also cleans at random. It can end up cleaning the same spot over and over, which can lead to needless battery drainage. You can, however, place the Virtual Walls so that the unit may navigate more effectively.


Both units may look relatively similar – but when it comes to their features, both of them have their differences. Here is what the Roomba 620 can provide you:

  • Dirt Detector
  • AeroForce 3-Stage Cleaning Technology
  • Virtual Walls Technology
    On the other hand, the Roomba 650 comes with the following features that each owner can enjoy:

  • 3-Stage Cleaning Technology
  • Auto-Floor Adjustment
  • Auto-Docking and Self-Recharging
  • Virtual Wall Technology
  • Convenient Scheduling
  • Recharge and Resume

While it may seem that there is a colossal difference between the two, most of it only deals with automation. The 650 can be programmed, whereas the 620 cannot; you will have to activate it yourself. Since the 650 can charge and resume its work without you even handling it, it can save you quite a lot of time.

With that in mind, when comparing Roomba 620 vs 650, we can’t deny the fact that the 650 model is clearly more superior. You don’t have to put this unit to charge; it will do the job for you instead.

The Overall Differences

The Roomba 620 may efficiently “see” bigger objects just as your refrigerator or the walls – but when it comes to smaller object, it might have a few difficulties. One example might be the legs of the tables and chairs – and the Roomba 620 will regularly collide with them. If by any chance the unit collides into something at high speed, it can even scratch or knock things off your furniture.

The Roomba 620 is rather “dumb” when it comes to its surroundings – so if left unattended, it can get stuck in various places. Unless you free it yourself, it will remain there frozen – vacuuming the same spot on and on. It doesn’t have a multi-room navigational system, so it won’t go purposely from one room to another. If it does change room, rest assured, it will be by accident.

While it may have the feature for Virtual Walls installment, they do not come along with the Roomba 620. You will have to make the investment yourself. If you do decide to go through with it, it can improve the navigational system of your Roomba.

Similar to the 620, the 650 also has its difficulties detecting certain obstacles. Some reviewers claimed that their 650 fell down the stairs, whereas others said that it managed to lock itself in the bathroom. As a result, if you want proper cleaning, the Roomba 650 also needs babysitting – just like its older sibling.

What differentiates the Roomba 650 from the Roomba 620 is its independence. Sure, you’ll still have to watch it as well – but at least, when it has finished its job, it will dock itself into charging mode. This way, there won’t be any instances of “oh, I forgot to charge it.” When the 650 is hungry, it will go get its own food.

Final Thoughts

In our Roomba 620 vs 650 review, it has been agreed upon that the Roomba 650 is superior to the 620 – but not necessarily because of its cleaning ability. Both models can suck the dirt in the same manner – and both can get “confused” about where they have to go.

However, the 650 wins for the fact that it’s more automated compared to the 520. It can dock itself, charge itself – and then resume itself at the programmed hours. It may be more expensive, but most people consider the investment worth it.
