Robot vacuum cleaner with air agitation
First Claim
Patent Images
1. A robot vacuum cleaner comprising:
- a cleaner body having a suction port through which contaminants can be drawn in from a cleaning surface;
an air agitation device mounted in said cleaner body to provide an air jet to the cleaning surface to dislodge contaminants;
an agitation brush operatively coupled to said suction port to provide additional agitation to the cleaning surface; and
a skirt sealing member of a continuous resiliently deformable material protruding from a lower surface of said cleaner body to contact the cleaning surface and surrounding both said suction port and said air jet exit opening for containing dislodged contaminants.

Abstract
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.

4. A robot vacuum cleaner comprising:
-
a cleaner body having a suction port through which contaminants can be drawn in from a cleaning surface; an air agitation device mounted in said cleaner body to provide an air jet to the cleaning surface to dislodge contaminants, said air agitation device comprising an air inlet equipped with a filter for filtering contaminant-laden air drawn in through said suction port, an air jet exit opening proximate said suction port, and a circulating path to jet filtered air through said air jet exit opening; an agitation brush operatively coupled to said suction port to provide additional agitation to the cleaning surface; a circulating pump in said circulating path operatively coupling said air inlet and said air jet exit opening; and a skirt sealing member of a continuous resiliently deformable material protruding from a lower surface of said cleaner body to contact the cleaning surface and surrounding both said suction port and said air jet exit opening for containing dislodged contaminants.
