ROBOTIC VACUUM CLEANER
First Claim
1. A robotic vacuum cleaner comprising:
- a housing;
a drive arrangement being configured to drive the vacuum cleaner along a surface to be cleaned;
a vacuum producing unit;
a debris receptacle; and
a nozzle inlet arranged in a portion of the housing facing the surface to be cleaned, the nozzle inlet comprising a frame structure having;
an opening in fluid communication with the debris receptacle and the vacuum producing unit;
a leading edge portion bordering on a first side of the opening;
a trailing edge portion bordering on a second side of the opening, the second side being opposite the first side;
a base portion extending substantially in parallel with the surface to be cleaned, the base portion extending at a first level;
at least two distance members located on the leading edge portion and forming there between a channel to the opening, the channel having a delimiting surface extending at a second level substantially in parallel with the first level, the first level being arranged closer to the surface to be cleaned than the second level, wherein each distance member has a substantially triangular cross section extending substantially in parallel with the first level, the distance member extending between the first level and the second level with a top of the substantially triangular cross section facing outwardly from the opening and a base of the substantially triangular cross section extending in parallel with the opening, and wherein side surfaces of the distance member extend substantially from the top to the base of the substantially triangular cross section, at least a portion of the side surfaces extending substantially perpendicularly to the base portion.

Abstract
A robotic vacuum cleaner having a nozzle inlet arranged in a portion of a housing of the vacuum cleaner. The nozzle inlet has a frame structure forming an opening. The frame structure has a base portion extending substantially in parallel with a surface to be cleaned, the base portion extending at a first level. A leading edge portion has at least two distance members forming there between a channel to the opening. The channel has a delimiting surface extending at a second level substantially in parallel with the first level. The first level is arranged closer to the surface to be cleaned than the second level. Each distance member has a substantially triangular cross section. At least a portion of side surfaces of the distance members extend substantially perpendicularly to the base portion.
