Robot vacuum cleaner with air agitation

摘要

A robot vacuum cleaner comprises a cleaner body having a wheel disposed at a lower portion and a suction port through which contaminants are drawn in from a cleaning surface; and an air circulating mechanism for filtering out contaminants from the contaminant-laden air drawn in through the suction port and then jetting the contaminant-free air to an air jet opening to help dislodge contaminants from the cleaning surface. The air jet opening is adjacent to the suction port; and the two elements are surrounded by a sealing member for sealing off a portion between the cleaning surface and the cleaner body to prevent dislodged contaminants from being dispersed outwardly.
