Evacuation station for a mobile floor cleaning robot
An evacuation station for a mobile floor cleaning robot comprises a housing and an air treatment assembly removably mountable to the housing. The air treatment assembly is provided on a first lateral housing end. The first lateral housing end is provided with a housing air inlet that is downstream of the air treatment assembly air outlet whereby the air treatment assembly air outlet faces the housing air inlet.
1. An evacuation station for a surface cleaning apparatus, the evacuation station having a front surface cleaning apparatus docking side, a rear side and first and second opposed evacuation station ends that are spaced apart in a lateral direction, the evacuation station comprising:
(a) an air flow path extending from an evacuation station air inlet to an evacuation station air outlet;
(b) a housing having the evacuation station air inlet, the evacuation station air outlet, first and second opposed housing ends that are spaced apart in a lateral direction; and,
(c) an air treatment assembly comprising a chamber, the chamber having a chamber air inlet and a chamber air outlet, wherein a first laterally extending wall of the chamber comprises a screen which comprises the chamber air outlet,
wherein the air treatment assembly is provided on a first lateral housing end and the first lateral housing end is provided with a housing air inlet that is downstream of the air treatment assembly air outlet whereby the chamber air outlet faces the housing air inlet, and
wherein the air treatment assembly is removably mountable to the housing, and
wherein the evacuation station air inlet is in fluid communication with an outlet port of the surface cleaning apparatus when the surface cleaning apparatus is docked with the evacuation station.
2. The evacuation station of claim 1 wherein the evacuation station has a lateral length between the first and second opposed evacuation station ends and the evacuation station air inlet is positioned at about a midpoint of the lateral length of the evacuation station.
3. The evacuation station of claim 1 wherein the air flow path comprises an upstream air flow path portion that extends from the evacuation station air inlet to the chamber and includes the chamber air inlet and the upstream portion of the air flow path extends through the first laterally extending wall.
4. The evacuation station of claim 1 wherein the evacuation station has a height which is proximate the height of the surface cleaning apparatus.
5. The evacuation station of claim 1 wherein the chamber has an upper end, a lower end and first and second opposed sides that extend laterally and are positioned between the upper and lower ends of the chamber, and the chamber air inlet is provided in the first opposed side.
