Roomba vacuum cleaners come with inbuilt advanced technologies and a wide range of sensors. This explains why they have very intelligent floor navigation. They can easily detect obstacles and avoid them by changing direction. They can also identify staircases so they cannot fall over. This review, however, shall focus on two versions of the Roomba vacuum cleaners. That is, Roomba 614 vs 675.

For the best cleaning experience and better technology, we recommend Roomba 675 for you. You can schedule your robot to do cleaning even in your absence. The Roomba 675 gives you the convenience you need since it can be remotely controlled using your Smartphone. Also, considering its better cleaning performance, we think this is the home cleaning tool you need.

Though, the Roomba 614 comes with adequate technology needed for any robot vacuum cleaner. It does have a few shortfalls when compared to the Roomba 675 as we shall see below.

Features of the Roomba 614

Let us kick this off with the Roomba 614. Roomba 614 is housed in a circular model design that you can quite easily accommodate. It is available on Amazon and can be shipped to your doorstep. This section lays out in detail everything you need to know before purchasing the Roomba 614.

Technology and Efficiency

Roomba is based on AeroVac technology which ensures effectiveness and ease of operation. With its thorough cleaning process, there is no chance for missing out dirty spots while vacuuming. Its circular shape allows the Roomba 614 to effectively use these three stages of cleaning as follows;

The first stage of vacuuming

In the first vacuuming stage, Roomba uses its inbuilt side revolving brushes. These brushes are used to clean walls before vacuuming starts.  It involves a variety of sensors that must detect if it’s either a wall or some other obstacle. Using this intelligence, Roomba gains the ability to clean around walls and raised upright surfaces. Such places include sideboards or even shelves, making it an effective and efficient cleaning tool.

The second stage of vacuuming

The second stage is focused around vacuuming the floor rather than the walls. Unlike in the first stage, this time round, Roomba makes use of two sets of brushes revolving in conflicting courses. They usually emerge from its base. The reason for this mechanism is that the dirt collected must be stuffed into the vacuum without pouring back onto the floor. This ensures that no spot is left out and thorough cleaning is done on each section of the flooring or carpets.

The third stage of vacuuming

Dirt has already been removed from walls and floor surfaces around. Roomba 614 then clears the way for the vacuum to perform the real cleaning by sucking all dirt into its inbuilt vacuum bin. This is the last stage before Roomba 614 navigates to another spot. It happens very swiftly to leave a very flawlessly clean surface without you realizing the stages behind it.

Dirt Filtration Mechanism

To deal with dirt collected from wall surfaces, floors and carpets, Roomba 614 uses AeroVac filters. These ensure that dirt collected from all these surfaces is collected into the bin. There is no chance for it to fall back to the vacuumed sections of your room. One thing to consider in this case is how often you clean up these filters because they are likely to get stuffed. And this all depends on how dirty your room is.


Roomba 614 doesn’t take a straight line while vacuuming a room. The next question probably on your lips must be; how does it clean the entire room without missing a spot? The answer is iAdapt Technology.

This enables Roomba sensors to detect the untidy sections of the floor, and the robot will attend to them first.  Note that, the time it takes this autonomous vacuum cleaner to tidy up a section of the floor depends on how dirty the floor is.

An important aspect to note about Roomba 614 is; it comes with a very good rechargeable Lithium-ion battery. This is capable of doing a complete and thorough cleaning session.

Dual Multi-surface brushes

Roomba 614 comes with Dual multi-surface brushes capable of removing dirt from hard floors and carpets. It also has the Edge-sweeping brushes responsible for sweeping around edges and corners. These brushes capture and remove large dirt particles from the floor. The navigation of the first brush ensures that dirt particles are loosened from the floor. Then, they are lifted and pulled towards the machine before being moved into the suction channel.


Roomba uses sensors to sense and eliminate dirt. These enable it to locate the untidy part of your room and the robot will clean them.

Cliff Detector

Roomba 614 won’t fall downstairs. The inbuilt sensors give Roomba 614 intelligent navigation around the floor. It can detect cliffs and drop-offs. In addition to that, the robot can go under and around the furniture to help you clean the floor.
