What is lidar in a robot vacuum cleaner?

The popularity of robotic vacuum cleaners is growing incredibly every year. And with it comes the need for new functions. So, today buyers are considering for purchase models with lidar. Devices with laser navigation and the ability to build and memorize cleaning maps are more expensive, but they make a person’s life much easier.

Why is lidar needed in robot vacuum cleaners?

Most well-known companies today have produced at least one model with a laser rangefinder included. Their cost is quite high and starts from 17 thousand rubles, but this does not stop lovers of real comfort from purchasing them.

Visually, the lidar is a small turret on the body of the robot vacuum cleaner.

This is the same laser rangefinder that manufacturers are talking about. The principle of their operation is quite simple. The vacuum cleaner sends light pulses into space and calculates the time it takes for them to reach the obstacle. This allows the device to determine the exact distance to furniture, walls and various obstacles.

The data obtained allows you to create a detailed map of the premises and select optimal cleaning routes. Hygienic procedures become clear and fast, without unnecessary movements of the device.

In addition, the lidar rotates in a horizontal plane and inspects the room every second at 360 degrees.

Modern robots with lidar navigate in space both day and night.They are perfectly detected in the room, in relation to vacuum cleaners equipped with cameras. With high-quality maintenance and timely replacement of parts, such a device will last three or more years.

Lidar has a significant disadvantage - it does not see reflective surfaces. If the room has a wardrobe with reflective doors or a floor-length mirror, it will not identify it. Also, the route does not include chrome legs of furniture (for example, chairs or a kitchen table), which is extremely inconvenient. However, you will have to come to terms with this feature.
