Over the past few years robot vacuum cleaners have become the latest and most sought after addition to the current home automation trend. These highly advanced, hardworking and compact gadgets have totally changed how users conduct their house cleaning chores, specifically vacuuming and mopping floors.

You might have noticed that most robot vacuum models come in different shapes, with the most popular options being D- shaped and circular or round shaped. If you are considering buying a new robot vacuum, but don’t know which one you should go with, here’s everything you need to know about D-shaped vs round shaped robot vacuum cleaners.

What Is A Robot Vacuum Cleaner?

Before we look at D shaped vs round shaped vacuum cleaners, it is important that we take a moment to define what these gadgets are. A robot vacuum cleaner is designed to clean the dirt off various floor surfaces whether carpeted, hardwood or tiled, autonomously.

On top of their cleaning abilities, robot vacuum cleaners are capable of mapping floor surfaces to work out the size of the room and the furniture in it. In addition to that they can automatically control their settings to suit the floor type in question, as identified by their inbuilt sensors. These gadgets also put themselves away once they are done cleaning.

Why Robot Vacuum Cleaners

Today, robotic vacuums are in high demand. This is mainly due to their numerous advantages, which include efficient operation and ease of use.

However the most significant advantage is linked to their convenient and time saving nature. With one, you no longer have to spend time vacuuming your floors manually.

Furthermore, unlike traditional vacuum cleaners, these gadgets do not use any cables, and are easy to store away on their base dock where they are kept fully charged ready for action. The charging base not only keeps your robot vacs charged but can also be used as the starting point when mapping the rooms around your house, if your model has this advanced feature.

To ensure that your floors are cleaned to your satisfaction, on a regular basis, you simply need to set the daily timer and leave it to handle the rest.

Now that you have a clear idea about what a robot cleaner is, and why it is now considered to be a must have gadget by an increasing number of home owners today, we can move on to comparing the two main designs, D-shaped and round-shaped.

D-Shaped Or Round-Shaped Robot Vacuum Cleaners?

A robot vacuum cleaner needs to operate autonomously. This means that it should be able to move around in the space being cleaned without requiring any human intervention whatsoever. One of the main reasons why most are designed round shaped is to ensure easy control of navigation around furniture.

It is hard for a circular object to find its way into a spot that it cannot get out of. Round shaped vacuum cleaners can simply turn around until they find their way out of any tight spots when performing cleaning duties.

D-shaped vacuum cleaners on the other hand are a bit more prone to getting stuck in tight spots simply due to their corners. It is however worth mentioning that these robot vacuums are designed with a variety of sensors that are meant to prevent such occurrences.

This means that the most advanced D-shaped robots face the same chance of getting stuck in tight spots as their round counterparts with as much ability to avoid the situation.

Effective And Efficient Cleaning

The main aim of having a D-shaped design is to ensure that the cleaner gets as close to wall edges and corners as possible to pick up dirt.

If you have used a round robot vacuum you will attest to the fact that they do struggle with getting dirt and debris located close to wall edges and corners. This is mainly due to the fact that their brush is located in the middle of the circular shape, far away from the edge. To address this weakness, a spinning side cleaning brush is included in the circular design to sweep the dirt into the suction stream.

Since D-shaped models have their brush located on the flat edge, which gives them the ability to clean closer to wall edges and deeper into tight corners. Some still have side brushes to help get dirt around awkward objects. This feature allows the suction to pick up more dirt leaving your house looking cleaner.

Brush Size

The amount of space that a robot vacuum can clean in one go depends on the breadth of its cleaning brush. The broader the brush, the larger the space the vacuum can clean in one go. This actually results in a higher cleaning, or vacuuming, efficiency.

D-shaped robot vacuum cleaners usually come with wider cleaning brushes simply due to their design. The brush spans the length of the flat edge. This essentially makes them much more efficient than their circular counterparts because they need less passes to clean the floor.

Even though the brush is located in the middle of circular vacuum cleaners, their widest point, the positioning of wheels on the edges of the brush means that is it narrower. On a budget robot vacuum the brush might not even span the whole width of the unit.

Collisions And Damage

The shape of a robot vacuum determines how much damage it can cause if and when it collides with other objects located within its space of operation.

Circular vacuum cleaners are said to present a lower risk of causing major dents, cracks or scratches on the surface of any object it runs into. This is due to their soft round edges and bumper sensors.

Since D-shaped vacuum cleaners have two corners, where the flat edge meets the curved edge, there is a higher chance that they may cause more noticeable damage in case of collisions. However, since these vacuums are designed with a variety of sensors meant to prevent collisions with other objects, the risk of such occurrences is minimal.

Aesthetics

It is true that the shape has an influence on how aesthetically appealing buyers find a robot vacuum. This does not influence the effectiveness of these devices when it comes to delivering the best vacuuming results. The smooth rounded curves on a circular vacuum make it more aesthetically appealing according to today’s trends.

However, even though D-shaped alternatives have corners, they are in no way considered to be an eyesore.

Latest Models

A testament to the effectiveness of the D-shape in robotic vacuum cleaners is the fact that iRobot who manufacture the Roomba have changed to it in their newer cleaners like the iRobot Roomba S9.

These premium robot vacuums offer so many features to make hands off cleaning the way to go. The clean base storage sucks out the dirt from the vacuum into it’s own storage bag meaning you don’t need to empty as often.

This is a higher price item but it offers amazing suction power making it suitable for hardwood floors or carpets and a boon for pet owners.

With the mapping feature it gives navigation that will cover the whole floor space using the most efficient lines to get into all the tight spaces. It even offers a virtual wall to restrict access to any areas of your choosing. 

If you have a smart home and want the ability to use voice control with Amazon Alexa or Google assistant then you can.

Conclusion

As a customer,  there are many factors to consider when it comes to buying the right robot cleaner. Price, features and the ability to do the cleaning jobs you need in your home, usually rank highly.

The d-shape design with its specific turning and edge cleaning technology might just make the difference to your daily cleaning.
