How does a robot vacuum cleaner work with building a map of the room? What is it and is it worth buying?

A robot vacuum cleaner with a room map does not just clean the floor, but also builds a detailed map, as well as a movement trajectory. Thanks to this, he consistently removes every centimeter without duplicating the movement. The features of such devices, their pros and cons are discussed in this article.

How does a robot vacuum cleaner work?

The fundamental difference between this vacuum cleaner and traditional models is the presence of several sensors. They are built into the body of the unit and allow it to navigate the room well and perform effective cleaning with minimal electricity consumption. A robot vacuum cleaner with mapping can plot the optimal trajectory thanks to several additions:

1. Distance sensors (contact or ultrasonic).
2. Camera on the cover with processor.
3. Lidar is a laser distance meter. It rotates during cleaning and transmits data about the distance to each nearest object to the control module.

Thanks to the built map of the room, the robot vacuum cleaner cleans literally every square centimeter. At the same time, it does not process the same surface several times, which increases work efficiency.

The use of such a device is justified if the area of ​​the apartment exceeds 50 m2.In such cases, using a conventional robot can be difficult, since it does not remember the places that have already been cleaned and does not guarantee total treatment of all corners.

Pros and cons of a robot vacuum cleaner

Robot vacuum cleaners with room mapping technology have several obvious advantages:

• cleaning is carried out independently without human intervention, which is especially important for older people;
• building a map of the room by the robot guarantees effective cleaning of every corner: the vacuum cleaner remembers the places where it has already been;
• you can start the process almost any time using an application on your phone;
• the device works autonomously, there is no risk of getting tangled in wires;
• the device is compact, so it can be taken anywhere;
• the noise level is much lower than that of traditional models;
• electricity costs are minimal, and the result is consistently high quality;
• Universal purpose - can process any type of surface.

There are also disadvantages, but they relate only to the cleaning technology itself. For example, a device with sensors that determine distance is already considered obsolete. Such a robot vacuum cleaner takes much longer to build a map of the room, and does not take into account changes in real time (for example, the movement of a person or animal).

Devices with a camera do not have these shortcomings, but they are quite difficult to move in a room with poor lighting. You also need to take into account that the camera calculates the floor area based on the ceiling without taking into account the arranged furniture and other items. But if the model is equipped with ultrasonic sensors, this disadvantage does not exist.

Models with laser distance meters are more advanced. However, they may misjudge the distance near black furniture or near a mirror.If possible, such items should be removed during cleaning.

Thus, a robot vacuum cleaner with a room mapping function is truly more advanced than conventional devices. It usually costs more, but in terms of convenience it surpasses even the most advanced devices. It’s very easy to understand the controls – all you have to do is trust the cleaning equipment and go about your business.
