Best Robot Vacuum Cleaner: Which to Buy

An automatic vacuum cleaner means an electronic device that is able to clean the surfaces of a given environment autonomously, but at the same time is able to recognize the obstacles and dangers of that particular environment. This type of devices is precisely called robot vacuum cleaner and we have already spoken in our dedicated purchasing guide.


After all, this is the end of home automation: making the home environment easier to manage and always connected! With robot vacuum cleaner you can control everything through a simple application, or at least leave the house while he will worry about cleaning one or more rooms. But before seeing what are the best models, let’s see the main features.

Best Robot Vacuum Cleaner: What can it do

Before buying any robotic vacuum cleaner, especially if it is your first robot vacuum cleaner, it is important that you analyze the main features of such a device immediately. In fact, they vary a lot depending on the price, allowing you to do more or less transactions.

In general, we can attribute common characteristics to all robotic vacuum cleaners, and based on these characteristics you will decide what you need by automatic framing in the price range best suited to your needs. Let’s see what these characteristics are:

  • Battery: it is one of the first characteristics that must be taken into consideration. The robot vacuum cleaner may be able to work between 30 and 60 minutes depending on the battery capacity or the power used to clean.
  • Charging: speaking of battery it is impossible not to mention the charging methods. The robotic vacuum cleaners can be powered by simple replaceable batteries (usually only the cheaper ones) or integrated and rechargeable lithium batteries (just like those of smartphones). In this last case or you will have to put them in charge when the work is finished, or they will return to the charging station autonomously.
  • Floor: another very important parameter, often left to chance, is the type of floor on which you intend to use the robot. If you have special needs such as parquet or carpets that you want to clean, this aspect is of primary importance.
  • Clothing and dust-bin: Robot vacuum cleaner can clean or use microfibre cloths (usually only the cheapest ones), or vacuuming the dust with an electric motor. In this case, you will have a tank to be emptied and cleaned periodically, and in many cases, there will also be a filter to change.
  • Power: when talking about robotic vacuum cleaners, it is also important to inquire about their power suction. Greater power means better suction and therefore deeper cleaning, but obviously, the noise decibels will also increase. Generally, 20/30 Watt is required for a good vacuum cleaner.
  • Sensors: is the most important part of an automatic vacuum cleaner. The more sensors are installed, the more intelligent and self-sufficient the robot is. There are sensors of all kinds, but among the most important we remember the fall sensor with which the robot will not fall from steps, the infrared sensor (almost always present) to avoid obstacles and entanglements, the wall sensor to create an artificial barrier that the robot cannot overcome, so to confine it in a single room or to exclude it from a particular room and much more.

It is not really a robot vacuum cleaner because it does not vacuum the dust, but the “capture” thanks to the electrostatic cloths (3 are already present in the package). This is a small device and with little power, therefore usable only with superficial dirt such as dust, hairs and crumbs.
