Robot cleaner

Abstract

A robot vacuum cleaner comprises a main body having a driving wheel, a suction port provided underneath the main body for drawing in contaminants on a surface to be cleaned, and a guide member disposed underneath the main body for guiding contaminants on the surface to be cleaned toward the suction port.

1 . A robot vacuum cleaner comprising: 
 a main body having a driving wheel;    a suction port provided underneath the main body, for drawing in contaminants on a surface to be cleaned; and    a guide member disposed underneath the main body for guiding contaminants on the surface to be cleaned toward a location adjacent to the suction port.    
   
   
       2 . The robot vacuum cleaner according to  claim 1 , wherein a pair of the guide members are mounted on opposite ends of the suction port.  
   
   
       3 . The robot vacuum cleaner according to  claim 1 , wherein the guide member is in contact with the surface to be cleaned and extends laterally beyond the driving wheel.  
   
   
       4 . The robot vacuum cleaner according to  claim 1 , wherein the guide member is made of resiliently transformable material.  
   
   
       5 . The robot vacuum cleaner according to  claim 1 , wherein the guide member further comprises: 
 a support connected with the underside of the main body; and    a guiding part extending upwardly from the support, and configured to contact the surface to be cleaned.    
   
   
       6 . The robot vacuum cleaner according to  claim 5 , wherein the upper portion of the guiding part connection with the support of the main body is thicker than the extended portion configured for contact with the surface to be cleaned.  
   
   
       7 . The robot vacuum cleaner according to  claim 1 , wherein the guide member extends away from the suction port and toward that side of the main body for which the guide portion is intended to clean.  
   
   
       8 . The robot vacuum cleaner according to  claim 1 , wherein the guide member is shaped and configured to collect the contaminants on the surface to be cleaned and to direct the contaminants toward the suction port.  
   
   
       9 . The robot vacuum cleaner according to  claim 1 , wherein the suction port is located behind the driving wheel in relation to the direction of expected travel of the main body.  
   
   
       10 . The robot vacuum cleaner according to  claim 1 , wherein the suction port extends for a predetermined length in a direction parallel to the rotation axis of the driving wheel; and 
 the guide member extends from opposite ends of the suction port.    
   
   
       11 . The robot vacuum cleaner according to  claim 10 , further comprising a main brush mounted on the underside of the main body extending in a direction parallel to the suction port, and is shaped and configured for providing contaminants on the surface to be cleaned easy access to the suction port.  
   
   
       12 . The robot vacuum cleaner according to claim.  4 , wherein the guide member further comprises a Thermoplastic Poly Urethane (TPU).
