Robotic vacuum cleaner
First Claim
1. A robotic vacuum cleaner comprising:
- a housing;
a drive arrangement configured to drive the vacuum cleaner in a forward direction along a surface to be cleaned;
a vacuum producing unit;
a debris receptacle;
a nozzle inlet facing the surface to be cleaned, the nozzle inlet comprising a frame structure having;
an opening in fluid communication with the debris receptacle, the opening extending in a lateral direction that is perpendicular to the forward direction,a base portion adjacent the opening and facing the surface to be cleaned, the base portion extending along a first plane that is substantially parallel with the surface to be cleaned,a side portion extending in the lateral direction from a lateral end of the opening to a lateral portion of the housing, the lateral end of the opening defines a lateral boundary of the opening, the side portion comprising;
a sloped region begins sloping from the lateral end of the opening and continues to slope towards the lateral portion of the housing, anda side brush mounting region extending from the sloped region towards the lateral portion of the housing,wherein the side brush mounting region extends in a second plane that is substantially parallel with the surface to be cleaned, the second plane being further from the surface to be cleaned than the first plane, and the sloped portion is sloped away from the first plane starting at the lateral end of the opening and ending at the side brush mounting region; and
a rotatable side brush mounted in the side brush mounting region and having a rotation axis, the rotatable side brush comprising bristles extending in a direction substantially outwardly from the rotation axis and substantially in parallel with the surface to be cleaned, and wherein during rotation of the rotatable side brush the bristles extend at least to the lateral portion of the housing and to the lateral end of the opening.

Abstract
A robotic vacuum cleaner having a nozzle inlet facing a surface to be cleaned, and a rotatable side brush. The rotatable side brush has bristles extending substantially in parallel with the surface to be cleaned, and the nozzle inlet includes a frame structure forming an opening, the opening being arranged in fluid communication with a debris receptacle. The bristles extend over a side portion of the nozzle inlet. The frame structure has a base portion extending substantially in parallel with the surface to be cleaned. The base portion extends at a first level. The frame structure at the side portion extends substantially in parallel with the surface to be cleaned at a second level. The first level is arranged closer to the surface to be cleaned than the second level.
