The Roomba 600 Series

The iRobot 600 series aims to make everyday cleaning a simple and easy task.

These vacuums are a great place to start when it comes to smart cleaning, and the price point isn’t too far from some modern-day regular vacuums, either. 

It doesn’t mess around with its 3-stage cleaning system that will clean up any mess. It has dual multi-surface brushes that work together to pick up dust, dirt, and debris that is lying around on the floors.

The first brush will loosen, lift, and pull in dust, dirt, and hair from your carpets and floors, and the second brush accelerates debris into the suction channel.

These devices also have an auto-adjust cleaning head that is able to adapt to different height levels in order to keep the dual-brushes in close contact with a variety of floor surfaces.

This allows the machines to engage with both hard floors and carpets directly. No matter the surface, the 600 series vacuums will have you covered.

They even sport an edge-sweeping brush that is specifically engineered at a 27-degree angle so that it can sweep debris away from edges and corners.

You can’t go wrong with the 600 series of robot vacuum cleaners, as they work fast and efficiently to clean up the mess on any flooring.

The vacuum has power-lifting suction, which means that it can deliver 5X the air power for improved pick-up performance. Compared to some other series, this is an improvement.

This vacuum is also ideal for homes with pets as it has a premium 3-stage cleaning system that aims to clean the dirt and pet hair that you can see and even the allergens and dust that you can’t see.

The smart vacuum cleaner will take care of most of the work, and all you have to do is to rinse away the dirt or debris that has been left behind in the washable bin. This bin is waterproof and easy to clean, making your only job that much easier.

The dual multi-surface rubber brushes will adjust and flex so they can stay in constant contact with the floor, and they take no time at all to make these adjustments. This means that they don’t need to pause or take a break and can keep working on your floors.

There is also a full suite of sensors that works to intelligently navigate the robot under or around objects in the room.

It can even go under furniture to help thoroughly clean your floors. Finally, there is a high-efficiency filter that will trap up to 99% of cat and dog allergens that are lurking in your home.

In terms of usage, this product is really easy and convenient to use, and you can connect to and schedule the vacuum to do tasks from anywhere.

You can use the Alexa or Google Assistant voice commands to control your robot’s cleaning duties. There is an app that you can use with this product called iRobot Home, and you can use it to schedule and monitor cleaning sessions.

A really cool feature that this smart vacuum has is that it can run for up to 90 minutes, and then it will automatically dock to recharge its battery before heading back to work.

It features Roomba essential technology like Wi-Fi connection, smart navigation, patented dirt detect technology edge-sweeping brush, auto-adjust cleaning head, and the ability to work on both carpets and hardwood floors.

Included in the box are one Roomba Vacuum, one home base charging station, a cord, a user guide, and other documentation.

Navigation System

The navigation system is pretty basic, and it uses various sensors to allow the robot to find its way around your home and avoid any obstacles that may be in its way.

It is even able to find its way to its charging dock to put itself on charge. There are three types of primary sensors that it uses, which are touch sensors, bump sensors, and drop sensors.

When it is using the bump sensors, the robot can figure out when it is coming up to an obstacle that it cannot get around. This could be anything in the room like household furniture or even the wall.

If the robot can get around the object, it will keep going, but if it can’t, then it will change direction when the bump sensor is activated. It will turn around and head off in a different direction.

The drop sensors are used to let the robot know when it is approaching a drop or ledge like stairs. This works to prevent the robot from falling down the stairs and getting damaged.

It will do the same as the bump sensor does and turn around to go in a different direction away from the danger.

The final sensor is a large RCONN sensor that can be located on the top of the robot. This sensor will detect the signal beacon that is emitted from the home base charging station. This is so that the robot will know when it is time to head back to its dock to recharge its battery.

It can also be used to stop the robot from passing the beam that is created by the dual-mode virtual wall barrier.

The question of whether or not the navigation works is something else entirely. The system will work for the majority of the time, but it isn’t always spot on.

From time to time, the robot will bump into objects, but this isn’t significant enough to cause any damage.

The robot hasn’t been recorded to fall down the stairs, according to the product reviews, it just seems to not be able to navigate every single obstacle that it is presented with.


While this robot may not be perfect in every possible way, it still provides an excellent service that will save you some time in the cleaning department.

It has many great qualities and features that allow it to seamlessly clean every aspect of your floors with the highest efficiency.

It might bump into your furniture from time to time, but the navigation system works well 95% of the time to prevent such accidents from happening.

There aren’t yet any reports of this robot being damaged by bumping into things, and it doesn’t fall from heights, so you won’t have to worry about it getting damaged while it’s doing its job.

It is competitively priced and is a much more cost-effective option than some of the newer models of smart vacuums by the same company.

It provides you with great services at a much lower cost than some other models. You should consider whether the convenience of a smart robot vacuum is worth the expense, but for the time that it saves you, it could definitely be beneficial.

If you have a relatively large house, then it might be worth considering another model, but for those with standard-sized rooms, this robot will be perfectly suited to you.

You can be assured that it won’t skip any corners with its edge sweeping brush to get those bits that are harder to clean.

The only issue with this is that the vacuum is limited to cleaning just one floor. The alternative to this is to buy more than one vacuum, which can become quite costly, or keep moving your vacuum and its charging dock to different floors.

Something else that you should consider is the fact that the vacuum cleaner will change direction if it encounters an unavoidable object. This could mean that some spaces in the room aren’t getting cleaned because the robot cannot get to them.

It is up to you to decide whether or not this smart vacuum would make a beneficial addition to your home, but considering the specs and features that it has, this vacuum seems like a great choice.
