Roomba 620 Robot Vacuum Review

Vacuuming is an important part of housekeeping and luckily, we live in a world where we don’t have to settle with handheld vacuum machines just to get the work done.

We now have robot vacuums that can completely automate the vacuuming process. The iRobot Roomba 620 is one of them – a smart floor cleaner that comes with great features, and it’s reasonably priced, too.

Key Features

The iRobot Roomba 620 vacuum is a 33-watt machine that weighs about 11 pounds. For a small vacuum, it’s loaded with great features that make it an effective automated tool for cleaning. Below are some of its key features.

  • Dirt Detection feature allows the Roomba 620 to focus on dirtier spots. This technology is made possible by an acoustic sensor that ensures those particular areas with pet hair, dust, and dirt are spotless.
  • AeroVac technology gets rid of hair and other debris caught up in the brushes effectively. It’s a smart innovation that will help save time in cleaning the brushes since you don’t have to clean it up yourself.
  • iAdapt Responsive Cleaning feature uses a scanning technology and multiple features to provide thorough cleaning. It’s the feature responsible for cleaning edges of walls, which means it understands the environment. For example, the Roomba 620 can detect sudden drops and obstructions, and deters away from it.
  • Although the Roomba 620’s system lacks a built-in barrier to stop it from entering certain areas, it is Virtual Wall-compatible. This is a Roomba accessory users can install that commands the robot from entering a room.
  • The Roomba 620 has a smaller docking station that you can position anywhere. The gadget returns to the station automatically when not in use or is low in power.
  • Stronger suction power enables the Roomba 620 to perform a thorough cleaning, better than its 500 series models. It also prevents the device from going over certain areas blindingly.

What We Like

There are a lot of things likable about the Roomba 620, but we’ll start off with the bin. It’s cleverly hidden among the curves of the gadget, and it blends well with the machine’s modern colors. The green glow of the power button also accentuates well and makes a clear indication that the device is turned on.

Like most Roombas, the 620 also automatically returns to its charging dock, a neat feature perfect for people always on the go. It charges for about three hours, but unlike the 500 series has a cleaner look, making the Roomba 620 a standout.

When it comes to cleaning, the Roomba 620 does an exceptional job because of its fast learning curve especially in learning its environment. Because of its iAdapt feature, it doesn’t fail to avoid legs of furniture and even cables, and it has soft bumpers that prevent damage to easily breakable surfaces. The iRobot Roomba 620 can last up to 80 minutes when fully charged. Finally, this robot vacuum is budget friendly compared to other robotic vacuums with outrageous prices.

What We Did Not Like

One thing that may be a deal breaker for consumers is that the Roomba 620 lacks a scheduler, unlike other Roomba models. It demands to be scheduled manually each time when you have to use it. Another thing is that the virtual wall is not built in and it needs to be installed, but it’s a good thing that this robot vacuum is virtual wall-compatible, so you might want to purchase it to get the best of the Roomba 620. A full bin indicator is also lacking. You will have to check manually to find out if the bin is already full.

Roomba 620 Review

The primary reason why people buy robotic vacuums is their smart capabilities. Knowing the cleaning features of the Roomba 620 is another important topic that needs to be discussed. This vacuum has no problems detecting huge objects, stairs, and walls, but you might find yourself seeing the device getting stuck with things like legs of tables and chairs, especially upon using it for the first time and the vacuum hasn’t learned completely of its surroundings yet. That said, here’s how well the Roomba 620 can clean.

Carpet Cleaning

iRobot won’t keep on producing versions and versions of Roombas if the goal isn’t to improve its earlier models. That said, don’t expect the Roomba 620 to have the same power as the latest models such as the 900 series. For example, the Roomba 980 has a carpet boost feature, which the Roomba 620 lacks. This means that the Roomba 620 won’t be as detailed as the Roomba 980, but for homes with low pile carpeting, the gadget shouldn’t have problems. The Roomba 620, to put it bluntly, isn’t the vacuum ideal for deep cleaning. But it’s efficient as an everyday cleaner and prevents dust from piling up.

Hardfloor Cleaning

Homeowners with hard floors shouldn’t have a problem with the Roomba 620. It’s capable of cleaning most bare floor surfaces thoroughly, thanks to its dirt detection technology. The acoustic sensors will detect spots that have dirt and focuses on them meticulously.

Pet Hair Removal

The Roomba 620 picks up pet hair, although not as thorough as more advanced Roomba models. However, it will do its job in cleaning pet hairs that are not normally seen by most pet owners.

Ease of Use

The Roomba 620 does a decent job as a robotic vacuum and is very easy to use. After opening the box, simply plug it into its charging button, press the clean button, and then it starts cleaning. It doesn’t have a certain pattern, but it goes about randomly and will focus on an area that’s dirtier than everything else it passes through.

Scheduled Cleaning

The Roomba 620 is a very basic cleaning machine, which means it doesn’t have a scheduling feature that higher Roomba models have, sadly. It’s a potential deal breaker for a lot of consumers because you will have to turn on the machine manually each time you want it to clean. This also means it won’t clean on its own when you’re away working or on a vacation.

Charging/Battery Performance

When fully charged, the Roomba 620 can last up to 80 minutes of cleaning. It takes about three hours for the gadget to be fully charged. With proper care, the battery can last for many cleaning cycles before it needs replacement.


The Roomba 620 cleans for you, but it requires you as the user to clean it to prolong its life. After each use, it is advised that the bin is emptied and the whole machine cleaned. Even after a few short cleaning cycles, debris like fur, hair, dirt, and dust can begin to take a toll on your Roomba. It is therefore important to clean it thoroughly before using it again to make sure that it will clean thoroughly.


The Roomba 620 has a limited warranty of one year except for the batteries. Make sure to contact iRobot support as soon as something is wrong. Don’t wait past the one year mark to get warranty repair. Meanwhile, replacement guarantee and refund depends on the retailer.

The patented, 3-Stage Cleaning System of the Roomba 650 picks up dust, pet hair and large debris like cereal. Improved over the Roomba 620, the brush design allows the 650 to clean out dirt in some of the tightest spaces.

The Roomba 650 is designed in that tried-and-true circular style, with utilitarian black and gray trimmings and an industrial aesthetic. It is still one of the older models in iRobot’s product line, but it is of such high quality, so well-known and so well-regarded that it still earns a spot when it comes to efficient robotic vacuums.

The Roomba 690 vacuum offers lots of functionality for the price, including control via smartphone and support for voice commands through popular smart home devices.

However, if you want a more powerful and better-cleaning vacuum with these features, you might want to buy the Roomba 980 or the Roomba 960. The Roomba 690 still falls into iRobot’s older Roomba models.


As mentioned, the Roomba 620 is a basic robot vacuum. In fact, it is one of the simplest machines that iRobot had produced. Being basic, however, doesn’t mean that the gadget can’t be trusted. When it comes to keeping your house from accumulating dust and dirt, the 620 does a great job.

Those who decide on buying the Roomba 620 shouldn’t expect super advanced features like the newer models of Roombas have. For one, it doesn’t have a HEPA filter, which means that you might want to step away when the device has to clean incredibly dusty areas.

Otherwise, you might inhale dust because it lacks an air cleaning feature. You can’t schedule the 620 either. You will have to turn it on by yourself if you want it to perform a cleaning cycle, which is one of its drawbacks.

Those who have read about Roombas know for a fact that the onboard scheduling that newer Roomba models have can be very convenient, especially when you want your place cleaned before you get home. The thing that will encourage consumers to buy the Roomba 620 is likely to price related. As expected, it’s way affordable than the newer models.

Being budget friendly, most people who want a smart vacuum won’t hesitate to make a purchase just to see how a robot vacuum works. Overall, the Roomba 620 will make a great starter Roomba for first time Roomba users. It doesn’t cost much and will clean your whole house with a push of a button.

Should you want something smarter, be prepared to shell out a bigger amount. But for people with small homes or those who live in a limited space, the Roomba 620 is highly recommended. There are many iRobot Roomba 620 reviews, but this one is our unbiased opinion of a great starter robot vacuum.
