What should you ask a robot vacuum cleaner?


After work, you will surely have a few hours of the day left to organize the house. And in case you have some time left, surely what you want the most (irony on mode) is to start cleaning. We can help you: a robot vacuum cleaner can be your great ally. Thanks to the technology, it will take care of you to keep the floor clean without the slightest effort. Forget worrying about dust, bread crumbs, or your pet’s hair. Your house will be pristine without you having to worry about it every day.

If you have decided to buy a robot cleaning machine and do not know where to start looking, do not worry. We have prepared a guide for everything you need to ask in this working program to keep your home in good condition.

Features that you should take into account when buying a robot vacuum cleaner

You certainly have many questions about which robot cleaning model to choose and which one fits your needs. Currently, there are many options in the market with different benefits and prices.

Before we move on to find a particular model, we explain everything you should look for before buying the desired robot.


You will find two types of robot vacuum cleaners: those with a central rotating brush and those without. The latter have instead a suction nozzle.

  • Robotic vacuum cleaners with a central rotating brush: they are recommended if you have rugs and rugs since they manage to brush the fibers and remove more dirt. They are most effective on hard surfaces by gently brushing the floor;
  • Robot vacuum cleaners without center rotating brush: they are limited only to vacuuming through the nozzle, without the brushing part. They have one main advantage: long hairs do not get tangled in the central rotating brush. Of course, every so often we will have to remove the hair manually.


The suction capacity of aspirators is measured in Pascals (Pa). This parameter measures the negative pressure that the robot motor is capable of generating through suction. Each manufacturer provides the suction capacity of each model.

As a tip, that a robot vacuum cleaner generates more Pascals of suction does not necessarily imply that it cleans better, since efficiency also comes into play.

Sensors, mapping, and navigation system

The vacuum cleaner’s sensors act like your eyes. The mapping is the brain, which processes the captured information and the navigation system, its cleaning behavior through our house. With this in mind, the most basic robot vacuum cleaners use infrared sensors and mechanical sensors. They can detect obstacles and unevenness at short distances or during contact.

The most advanced models include ultrasonic sensors (small internal radars), wide-angle cameras, or laser turrets that project beams of light to discover obstacles and map rooms. That is why many users have come to believe the urban legend that vacuum robots spy on us through mapping.

Depending on the navigation system, you will find two types of robot vacuum cleaners: those that act based exclusively on decisions made in real-time and those that are capable of recognizing the environment and remembering it, making decisions on the fly taking into account that stored information.

Those of the first category, when they encounter an obstacle, avoid it or evade it by default, but they do not remember the position of the obstacle, nor the maneuver they have used to get around it. If the robot finds this hindrance again, it will act in the same way, creating patterns and “vices” in its behavior that will lead it to repeat certain patterns inefficiently.
