Robot vacuum cleaner with air stirring

Abstract

A robot vacuum cleaner comprising a cleaner main body having wheels provided on a lower part and a suction port through which pollutants are sucked from a cleaning surface; Contaminants are filtered from the contaminated air and then non-contaminated air is injected into the air jets to dislodge the contaminants from the surface to be swept. The air injection port is adjacent to the suction port; and the two elements are surrounded by a seal for sealing the area between the sweeping surface and the cleaner body to prevent dislodged contaminants from being dispersed outward.

Description

technical field [0001] The present invention relates to a robotic vacuum cleaner, and more particularly to such a robotic vacuum cleaner provided with agitation to clean a surface by means of a jet of air directed towards the surface and the action of agitating the brushes. Background technique [0002] When a robotic vacuum cleaner operates autonomously over an area without being manually guided by a user, it typically sucks in contaminants such as dust from the surface being cleaned. The robotic vacuum cleaner detects obstacles such as furniture, appliances, or walls in the cleaning area by a distance detector relative to its position. The robot vacuum cleaner selectively drives the right wheel motor and / or the left wheel motor to automatically change its direction of travel, thereby performing sweeping operations in the sweeping area. [0003] Such as figure 1 As shown, a conventional robot vacuum cleaner includes a cleaner body 10 , a driving wheel 11 and a driven whee...

AI Technical Summary

Problems solved by technology

[0004] Conventional robot vacuums sometimes fail to completely remove contaminants, especially those embedded in carpet or stuck to the surface being cleaned

This can be particularly unpleasant and even harmful if fine contaminants such as dust, mites or other allergens remain
