Problems solved by technology

[0009] That is, the friction between the drive wheel and the floor is reduced, causing the drive wheel to slip, and increasing the drive load of the wheel, which reduces the travel time and reduces the mass of the robot cleaner
[0010] In addition, due to an increase in the load of the rotating brush, etc., the rotation speed of the brush decreases and the cleaning performance deteriorates

Abstract

A robotic vacuum cleaner includes: an autonomously moving vacuum cleaner body; a suction nozzle mounted so as to be able to ascend/descend or swing relative to the vacuum cleaner body; and a support member for supporting the suction nozzle so that the suction nozzle can ascend/descend or swing. Accordingly, driving performance is improved due to easy handling of a changing floor height, and an operation capable of assisting a vacuum cleaner in climbing across an obstacle may be achieved. In addition, even when the floor height changes greatly, the cleaning performance can be improved by maintaining the surface pressure of the suction nozzle and increasing the suction pressure.

Description

technical field [0001] The present disclosure relates to a robot cleaner capable of improving travel performance and cleaning performance by easily responding to changes in the floor on a travel path. Background technique [0002] A robot cleaner is a device that sucks in foreign objects, such as dust, from the floor as it travels over the area to be cleaned. [0003] The robot cleaner includes a suction nozzle module, and the suction nozzle module is in contact with a surface to be cleaned to suck in foreign matter such as dust on the surface together with air. In particular, robotic cleaners operate primarily in a floor environment. [0004] Meanwhile, when the robot cleaner travels in a state where the suction nozzle is fixed to the robot cleaner, the height of the floor may be changed according to various types of floor environments. [0005] For example, when a robotic cleaner travels, there are various types of travel environments, such as floorboards, floorboards, d...
