Upward and radial floor cleaning apparatus

Abstract

A robotic vacuum cleaning apparatus comprises: a head; a suction element to facilitate suction cleaning of a ground surface via the head; and a cleaning element.

1 . A robotic vacuum cleaning apparatus, comprising:
 a head, capable of robotic movement over a ground surface;   a suction element to facilitate suction cleaning of the ground surface via the head; and   a brushing arrangement that, in total, from a top view, travels outside and around at least a half of a perimeter of the head of the robotic vacuum cleaning apparatus, and comprises:
 a left brushing portion that travels outside and around at least a portion of a left side of the head of the robotic vacuum cleaning apparatus, and extends left further than the left side of the head, and itself travels outside and around at least a quarter of the perimeter of the head of the robotic vacuum cleaning apparatus; 
 a right brushing portion that travels outside and around at least a portion of a right side of the head of the robotic vacuum cleaning apparatus, and extends right further than the right side of the head, and itself travels outside and around at least a quarter of the perimeter of the head of the robotic vacuum cleaning apparatus; 
   wherein there is a front gap between the left brushing portion and the right brushing portion, in front of a front of the head of the robotic vacuum cleaning apparatus, and a back gap between the left brushing portion and the right brushing portion, behind a back of the head of the robotic vacuum cleaning apparatus.   
     
     
         2 . A robotic vacuum cleaning apparatus, comprising:
 a head, capable of robotic movement over a ground surface;   a suction element to facilitate suction cleaning of the ground surface via the head; and   a cleaning element that comprises a brushing portion that extends left further than a left side of the head;   wherein the robotic vacuum cleaning apparatus comprises another cleaning element, wherein the other cleaning element comprises a brushing portion that extends right further than a right side of the head.   
     
     
         3 . A robotic vacuum cleaning apparatus, comprising:
 a head;   a suction element to facilitate suction cleaning of a ground surface via the head; and   a cleaning element.   
     
     
         4 . A robotic vacuum cleaning apparatus as claimed in  claim 3 , wherein the cleaning element is removably attachable to the head, and comprises:
 a left brushing portion that extends left further than a left side of the head; and   a right brushing portion that extends right further than a right side of the head.
