Choosing the Best Robot Vacuum: Factors to Consider for Optimal Cleaning Performance


Robot vacuums have become increasingly popular in recent years, offering a convenient and efficient way to keep our homes clean. However, not all robot vacuums are created equal when it comes to cleaning performance. In this blog post, we will explore the factors that affect cleaning performance and discuss which robot vacuums are the best in this regard.

The Importance of Brush Configuration

One of the most important factors that determine a robot vacuum's cleaning performance is its brush configuration. While most robot vacuums have a disc shape with a main brush situated between the wheels, the best ones have brushes that span the full width of the unit. This allows them to clean right along the edges of your room and into the corners, ensuring a thorough clean.

Suction Power

Another crucial aspect to consider is the suction power of the robot vacuum. Typically measured in pascals (Pa), suction power indicates how powerful the motor is inside the vacuum. For effective cleaning, it is recommended to look for a robot vacuum with a suction power of around 2,000Pa or above. This ensures that the vacuum can effectively pick up dirt, dust, and debris from your floors.

Additional Factors to Consider

While brush configuration and suction power are key factors in determining cleaning performance, there are a few other factors to consider as well.

Bin Capacity

Robot vacuums need to be emptied more frequently than regular vacuums. Therefore, it is important to consider the bin capacity of the robot vacuum you choose. Bin capacities can vary from model to model, with the largest ones being around 0.7 litres in size. However, some models have larger bins built into their base stations that automatically empty into when charging. These models tend to be more expensive but offer the convenience of less frequent emptying.

Mop Attachments

As robot vacuums gain popularity, manufacturers are incorporating mop attachments as a way to differentiate their products. These attachments use a small water reservoir with a cleaning pad attached to the bottom, allowing the robot vacuum to mop the floor as it cleans. However, it is important to note that these mopping features are only effective for light dirt and dust on hard floors. Stubborn stains will still require manual cleaning with a proper mop.

Self Emptying

Some robot vacuums have the ability to empty themselves into a larger base-station bin and continue cleaning. While this feature offers convenience, it comes at a higher cost and requires more space in your home for the base station.


Robot vacuums are designed to clean below low-lying furniture, but their heights can vary. Before purchasing a robot vacuum, it is important to check its dimensions to ensure it will fit under your furniture.

How We Test Robot Vacuum Cleaners

At [Company Name], we take the testing of robot vacuum cleaners seriously to provide you with accurate and reliable information. We install each robot vacuum in a typical domestic setting with the charging station placed in the same location. This allows us to compare elements such as navigation and speed between different models.

During testing, each robot vacuum is connected to Wi-Fi and controlled through the supplied app, if available. We thoroughly test all the features and functions, including navigation to a second storey and the performance of self-emptying stations and mop attachments.

To analyze a robot's cleaning capabilities, we conduct tests using measured spillages of rice and flour. We send the robot to perform a spot clean of each spill on both carpet and hard floors and measure the amount collected each time. This enables us to compare the cleaning effectiveness of different robot vacuum cleaners.


When it comes to choosing a robot vacuum with the best cleaning performance, brush configuration and suction power are key factors to consider. Additionally, factors such as bin capacity, mop attachments, self-emptying capabilities, and height should also be taken into account based on your specific needs and preferences.

At [Company Name], we strive to provide you with comprehensive and unbiased information to help you make informed decisions. By considering these factors and understanding how we test robot vacuum cleaners, you can confidently choose a robot vacuum that will keep your home clean and tidy.
