Robot Vaccum Cleaner - Specs and Detials

The robot vacuum cleaners with a rounded design are agile in their movements and perfect for cleaning any environment.

Those with a square shape , on the other hand, are excellent for easily reaching the corners of the surfaces to be cleaned, especially if they are used in homes with a rather regular plan. Their right-angled shape allows the robot to skirt the walls of the rooms from side to side and to fit perfectly into the corners, which is more difficult for robots of other shapes.

tall robot, in fact, could encounter greater obstacles in homes with a lot of furniture and furnishings.

Robot vacuums have a built-in battery. Usually the instruction booklet, or the parent company itself, indicate what is the autonomy of the battery.

This detail is particularly important for those who are thinking about buying a robot vacuum cleaner. The greater the autonomy of the device and obviously the greater the area it can cover with a single session.

To date, a very important feature is the memory function of the clean path : if the device were to discharge during the cleaning phase without having completed the preset operation, it will be able to return to the charging base and resume its own operation. where it left off.

Precisely for this reason, since they are totally automatic devices, autonomy on the products we recommend is never a problem.

The tank of the robot vacuum cleaner is the container in which elements of dirt found on surfaces are collected. Before choosing a model it is important to evaluate its capacity because the autonomy of the appliance depends on it.

Generally, the lowest priced robots have a tank with a capacity of 250ml. The best ones, on the other hand, go up to 500 ml but not beyond considering that the robot has small dimensions.

A much requested feature, and present on devices from 2021 onwards, is the automatic emptying base . This is an accessory that sucks up all the dirt from the dust container onto a bag. The advantages are many: you no longer have to touch the dust (excellent for allergic people), the time taken to maintain the robot decreases and malfunctions are avoided.

The best robot vacuum cleaners are equipped with AI systems, that is Artificial Intelligence in English, which facilitate the self-learning of the machine.

In some models, especially those that are in a high price range, smart functions are added that improve the accuracy of the robot’s performance and its ability to interact with other devices such as smartphones and so on.

The main smart functions are:

  • Programming, which allows you to set house cleaning at any time via the app;
  • Compatibility with Google Assistant or Alexa, thanks to which it is possible to use robots with voice commands;
  • The mapping of the environment, which allows the appliance to incorporate the structure of the house and, therefore, avoid any obstacles thanks to the integrated camera;
  • Anti-tipping sensors, with which robots can recognize unevenness in the house and avoid them without problems;
  • Surface recognition sensors, with which the robot vacuum cleaners are able to understand what type of floor they are on (parquet, marble or carpet) and then set a specific cleaning program.

The parquet or the marble floor are very delicate, so they need robots with delicate brushes designed to clean these surfaces. If you do not take this precaution, in fact, the risk is to ruin the floors and get, in any case, a bad cleaning.

Height differences are also important when choosing a robot vacuum cleaner.

In a house articulated on several floors and, therefore, with several flights of stairs, it is better to buy a model that has an anti-rollover sensor and a function that allows the robot to stop if it perceives that it is facing a void, in case it is used. on the upper floors. The economic models make up for this lack with magnetic tape that can be affixed near stairs or rooms to keep out of its reach.

The top-of-the-range models have the ability to store and map different levels of the house: this is useful for cleaning on different floors, using the same product, having the foresight to move it from one floor to another. Another great advantage is that of being able to carry out a zone cleaning: everything is done via the smartphone app.
