Abstract

The present invention relates to a robotic vacuum cleaner, comprising: a vacuum cleaner main body in which a plurality of guide holders are provided, the vacuum cleaner main body traveling autonomously; and a suction nozzle in which an agitator is housed on the inside thereof, the suction nozzle being provided with guide protrusions protruding from both side walls of the suction nozzle in the longitudinal direction toward each of the plurality of guide holders, the guide protrusions being housed on the inside of each of the guide holders, and the guide protrusions protruding from both side walls of the suction nozzle toward each of the plurality of guide holders in the longitudinal direction. The suction nozzle is mounted so as to be liftable relative to the cleaner body and swingable in the front-rear direction, thereby improving the traveling performance and cleaning performance of the robot cleaner.

Description

technical field [0001] The present invention relates to a robot cleaner capable of improving traveling performance and cleaning performance by easily responding to changes in the ground on a traveling path. Background technique [0002] A robot vacuum cleaner is a device that sucks in dust and other foreign matter from the floor while traveling on its own over the area to be cleaned. [0003] The robot vacuum cleaner is provided with a suction nozzle module, which contacts the surface to be cleaned and sucks dust and other foreign matter on the surface together with air. In particular, robot vacuum cleaners mainly operate in the ground environment. [0004] On the other hand, when the robot cleaner travels with the suction nozzle fixed, there may be a difference in floor height depending on various floor environments. [0005] For example, when a robot cleaner travels, there are various travel environments such as floor leather, hardwood floors, door frames, tiles, rugs, a...
