Having been obsessing about home cleaning methods during the better part of three decades, I have become somewhat of a specialist. One of the most pleasant surprises I have had during all this time is discovering the joys of using a robot vacuum cleaner. Efficient, practical and incredibly convenient, a device of this kind can truly make a difference in your everyday life. With that in mind, today, I will review one of my previous favorite robot vacuums: the Roomba 620. Despite it not being the most powerful or advanced, I find that this product offers fantastic value and, as a result, it’s worth looking into. Hopefully, this iRobot Roomba 620 review will help you decide whether this product is the right one for you.

Things to Consider Before Buying a Robotic Vacuum Cleaner

If you, like me, don’t have the time or the energy to manually vacuum your house floors with regularity, a robotic vacuum cleaner can be a fantastic purchase. Using a built-in navigation system, such a device is capable of moving around your house on its own, cleaning the floor in a systematic fashion. Efficient and reliable, the best robot vacuums are truly capable of making your life easier. The only requirement for owning one is having regular flooring and a reasonably-uncluttered environment so that the robot can move around effectively.

If you are planning on buying one of these useful devices, read the following first:

Floor Type

Most modern robot vacuums can handle all types of floors. However, some of them are better suited for cleaning difficult surfaces such as carpeting. Take into account that, while low-pile carpeting doesn’t represent a big problem, high-pile carpeting often does. If you have high-pile carpeting in your home, look for a robot vacuum with enhanced traction and suction capabilities. If you want to find out more about floor types, check out this resource.

Home Size

Without a doubt, the size of your home is important to take into account. The more floor surface area there is to clean, the longer the device will have to work. For that reason, if your home is large, it’s best to get a robot vacuum with a long battery life.

Allergy Management

If you have allergies, try to get a robot vacuum that is equipped to deal with allergens, mites and other potential triggers. Typically, devices that have anti-allergen capabilities use a high-efficiency HEPA filter to capture and neutralize these particles.

Features and Benefits of the iRobot Roomba 620

iRobot Roomba 620 Vacuum Cleaning Robot

At long last, it’s time to go into the features and characteristics of the iRobot Roomba 620. Hopefully, this in-depth information will help you decide whether this is the right robot vacuum for your particular needs. Take the following into account:


Deviating from its predecessors, the Roomba 620 features a minimalistic black and white design that’s remarkably sleek and elegant. What is more, it’s more rounded than the previous Roomba models, increasing its protection against impact. Its circular shape allows it to move in 360 degrees, allowing it to maneuver with incredible efficiency. In addition, its low-profile allows it to reach difficult spots such as those under the furniture.


While it’s not the most powerful or the most advanced robot vacuum model on the market, the iRobot Roomba 620 performs very well. The first thing you have to know about its actual cleaning process is that it’s random. Once activated, the device will randomly move, looking for spots that need cleaning. However, due to its iAdapt system, it is actually capable of learning and adapting as it cleans, quickly improving the results. Even more than that, this system allows it to avoid obstacles and potential perils, preventing it from becoming stuck or, even worse, damaged.

Without a doubt, one of the best things about the Roomba 620 is its long battery life. This feature allows it to take its time when cleaning, making the most out of the robot’s three-stage cleaning system. By most accounts, this system is very effective despite the device not having smart capabilities. At any rate, iRobot included a dirt detection sensor that enables it to spend extra time on spots that require more cleaning. When its battery is running out, this device automatically returns to its dock for charging.

Navigation and Maneuverability

Because it doesn’t have any kind of mapping capabilities, the Roomba 620 is not as efficient at recognizing its surroundings as some of the more advanced models out there. Also as a result of not having mapping capabilities, the device moves randomly. Without a doubt, this hinders its navigating and maneuvering abilities. However, having a high-quality camera and various sensors, the Roomba 620 is still capable of making its way through your home looking for spots that need cleaning. In addition, the previously mentioned dirt detection feature allows it to avoid places that don’t need cleaning, saving battery life.


Without a doubt, one of the best things about the iRobot Roomba 620’s simplicity is that it makes it very user-friendly. In fact, it means it can be activated without the need for a remote control or a smartphone app. Instead, you only need to press a button so the device will begin its room-recognizing process. Once ready, the 620 will begin its randomized movement across the room. Once the cleaning process is complete (or it runs out of battery) the vacuum robot will automatically return to its charging dock and turn itself off.

Additional Features

In addition to the previously mentioned three-stage cleaning and auto-docking capabilities, the Roomba 620 has a few features worth being mentioned. Without a doubt, one of the most important is its ability to use virtual wall technology to manage and limit its movement area. Making the most out of this feature, you can prevent the vacuum robot from accessing problematic areas, falling down a flight of stairs and so on.

Another feature worth talking about is the vacuum robot’s Auto Floor Adjustment technology. This one uses sensors to understand differences in surface types and detect floor-level obstacles. The feature works perfectly with the Roomba 620’s iAdapt responsive cleaning system. As mentioned earlier, this system uses a camera and various sensors to detect obstacles and perils before running into them.


As I just mentioned, this Roomba model is capable of using virtual wall technology to limit its movement. Fortunately, the item includes one virtual wall that you can place anywhere in your home. If you need more, however, they can be bought separately. The 620 also includes a high-efficiency HEPA filter to help you protect yourself from dangerous allergens and other types of particles. Like the additional virtual walls, you can buy more of these filters separately as you see fit.

In order to provide evidence of my claims regarding this robotic vacuum cleaner, I scoured through the internet looking at user reviews. They confirmed my suspicions: To a lot of people out there, the Roomba 620 is an affordable, reliable and efficient robot vacuum cleaner. More than a few reviews stated that, despite not boasting state-of-the-art technologies of any kind, it’s remarkably good at what it does. In particular, people praised the device’s responsiveness, consistency, and reliability. Additionally, many happy customers talked about the robot vacuum’s obstacle-avoidance capabilities.
