Detailed Features

Body design, aesthetics, and build

As I said earlier, the Roomba 618 does not come with a so much attractive design that you’d love. It has an oval-shaped body which is the traditional shape of all Roomba vacuums. Looking at the gadget, you will notice the low-profile height which enables it to navigate under beds, sofas, and other furniture alike.

The Roomba 618 flaunts a sleek body aesthetics and its rounded corners add some clue of uniqueness to the design of the robot. iRobot has been manufacturing quality vacuuming robots for over 2 decades now and so have expertly crafted the design of this model for maximum efficiency.

Cleaning system and performance

This Roomba robot will diligently clean up your whole floors at the push of a button. It comes with a patented 3-Stage cleaning system which allows it to loosen, pick up, and suction every dirt, debris, allergens, etc on the floors. No matter the types of floor you have, this robotic vacuum is engineered to work on types of floors with optimum efficiency.

The robots cleaning head automatically adjusts whenever it senses a new type of floor different from the initial one it has been working on. Also, this model gets closer to wall edges and into tight corners to clean up the environment and assure a healthier and super clean environment.

Controlling this unit to work is not something that requires tutorials; you just press the clean button and off it goes to work.

Battery and docking

Unfortunately, Roomba 618 will not resume cleaning from where it stopped after a full charge although it returns to the dock automatically. So, you’ll have to take the bot back and press the clean button again for it to continue cleaning the floor

Luckily, before these all stresses will erupt, the robot must have worked for about 60 minutes. If the area it is being assigned to it is not wide, it could possibly finish cleaning the floor before the battery runs down.

IRobot also packed this unit with an Xlife extended instead of Li-Ion, promising up to 4x the battery cycle lifetime.

Navigation and sensors

Navigating through the house is quite easy for the Roomba 618 and coupled with a full suite of intelligent sensors, it hardly collides with other furniture in the house. This robotic vacuum also avoids the stairs and other drop-off points in the house to prevent it from damage.

Virtual Barrier Walls

These virtual barrier walls are what you will use to restrict the robot’s movement around the home. They draw virtual lines where the robot is not meant to bypass. This is applicable when you do not want the Roomba 618 to penetrate into certain areas of the house due to the presence of a delicate equipment of stuff of that nature.

Scheduled cleaning

The Roomba 618 supports scheduling. This means you can schedule the robot to clean up the floors up to 7 times per week in your absence. Setting a cleaning schedule will help this robot consistently keep your floor clean every day. A lot of robotic vacuums support this feature and same does the Roomba 618. Comfortably set your scheduled time using the buttons on the robot’s body.

Filters, sensors, and brush technology

IRobot tried to equip this model with a full suite of intelligent sensors and a good filter so it can pick up everything it finds on your floors.

Also, this model comes with dual multi-surface cleaning brushes, an edge sweeping brush, and other set of minor brushes. All engineered to deliver a very much effective cleaning result. 

I mentioned that Roomba 618 comes with a good filter – yes it does but it’s not a HEPA filter, just a normal filter.

Roomba 618 Review

There are a couple of competitors that would challenge the Roomba 618, but amongst all of them, it appears the best. It is obvious that Roomba 618 lacks a lot of useful features, but these features are not even available on its counterparts.

The virtual barrier walls support also helps to prevent the robot from falling off the various drop-off points at home. Roomba 618 picks up any kind of dirt, debris (large or small), hairs, and other particles if finds on the floor.

This Roomba 618 review article covers the whole aspect we think you may ask questions about the robot. Unfortunately, Roomba 618 is not packed with HEPA filters but with the native filters it has, it does its work perfectly.

Roomba 618 navigates freely under the beds, sofas and furniture alike. The navigation is sometimes questionable because it does collide with other equipment’s in the house, but this does not happen often. When the robot approaches an area with much dirt, it concentrates more on this area and ensures it becomes as clean as the others.

IRobot backs this unit with a solid one-year warranty support. So, you can buy the Roomba 618 with much confidence knowing it is replaceable if it disappoints within the warranty duration.

Conclusion and final thoughts

Compared with other robotic vacuums from other manufacturers sold at the price with this unit, the Roomba 618 offers a great value for the price tagged.

While you will not be able to control the robot with a remote control or from your smartphone, it is still very easy to operate using the buttons on its body.

Finally, in this Roomba 618 review, I’ll say this is a solid robotic vacuum you should get as a homeowner.
