Robotic vacuum cleaner and docking station for a robotic vacuum cleaner
A robotic vacuum cleaner docking station has a mechanical transfer mechanism that is used to transfer dirt from a robotic vacuum cleaner to a docking station.
1. An apparatus comprising a docking station and an autonomous surface cleaning apparatus wherein, the autonomous surface cleaning apparatus comprises:
(a) a primary air flow path extending from a dirty air inlet to a clean air outlet;
(b) a primary suction motor positioned in the primary air flow path; and
(c) an air treatment unit positioned in the primary air flow path, the air treatment unit comprising a dirt collection region;
and wherein the docking station comprises a dirt receptacle and a mechanical dirt transfer mechanism moveable between a first position and a second position, wherein when the mechanical dirt transfer mechanism moves between the first position and the second position, the mechanical dirt transfer mechanism physically engages dirt that has collected in the dirt collection region and transfers at least some of the dirt that has collected in the dirt collection region from the dirt collection region towards the dirt receptacle.
2. The apparatus of claim 1 wherein, when the autonomous surface cleaning apparatus is positioned on a floor, the air treatment unit has an upper side, a lower side, a first end having a first side positioned between the upper and lower sides and a second end having a second side positioned between the upper and lower sides, the second side is spaced apart from the first side in a first direction and, the mechanical dirt transfer mechanism is moveable in the first direction through at least a portion of the air treatment unit whereby dirt collected in the air treatment unit is moved in the first direction through the air treatment unit.
3. The apparatus of claim 1 wherein, when the autonomous surface cleaning apparatus is positioned on a floor, the air treatment unit has an upper side, a lower side, a first end having a first side positioned between the upper and lower sides and a second end having a second side positioned between the upper and lower sides, the second side is spaced apart from the first side in a first direction, the second side has a dirt outlet and, in a dirt emptying mode, the mechanical dirt transfer mechanism is moveable through the dirt outlet towards the first side and then moveable in the first direction back through the dirt outlet.
4. The apparatus of claim 3 wherein the mechanical dirt transfer mechanism comprises a sweeping portion and a drive portion, the sweeping portion is reconfigurable between in insertion position in which the sweeping portion is positioned above the lower side and a sweeping position in which the sweeping portion extends downwardly from the drive portion.
5. The apparatus of claim 1 wherein the autonomous surface cleaning apparatus has a robot bin door which closes a dirt outlet of the air treatment unit and the mechanical dirt transfer mechanism opens the robot bin door when the mechanical dirt transfer mechanism is actuated.
6. The apparatus of claim 1 wherein the docking station has an openable door which closes a dirt inlet of the dirt receptacle and the mechanical dirt transfer mechanism opens the openable door when the mechanical dirt transfer mechanism is actuated.
7. The apparatus of claim 6 wherein the autonomous surface cleaning apparatus has a robot bin door which closes a dirt outlet of the air treatment unit and the mechanical dirt transfer mechanism opens the robot bin door when the mechanical dirt transfer mechanism is actuated.
8. The apparatus of claim 1 wherein the autonomous surface cleaning apparatus has a robot bin door which closes a dirt outlet of the air treatment unit and the robot bin door is opened when the autonomous surface cleaning apparatus docks at the docking station.
9. The apparatus of claim 1 wherein the docking station has an openable door which closes a dirt inlet of the dirt receptacle and the openable door is opened when the autonomous surface cleaning apparatus docks at the docking station.
10. The apparatus of claim 9 wherein the autonomous surface cleaning apparatus has a robot bin door which closes a dirt outlet of the air treatment unit and the robot bin door is opened when the autonomous surface cleaning apparatus docks at the docking station.
11. The apparatus of claim 1 wherein the autonomous surface cleaning apparatus has a robot bin door which closes a dirt outlet of the air treatment unit and the robot bin door is opened when an emptying mode of the autonomous surface cleaning apparatus is actuated.
12. The apparatus of claim 1 wherein the docking station has an openable door which closes a dirt inlet of the dirt receptacle and the openable door is opened when an emptying mode of the autonomous surface cleaning apparatus is actuated.
13. The apparatus of claim 12 wherein the autonomous surface cleaning apparatus has a robot bin door which closes a dirt outlet of the air treatment unit and the robot bin door is opened when an emptying mode of the autonomous surface cleaning apparatus is actuated.
14. The apparatus of claim 1 further comprising a pneumatic dirt transfer mechanism.
15. The apparatus of claim 14 wherein the autonomous surface cleaning apparatus has the pneumatic dirt transfer mechanism.
16. The apparatus of claim 1 wherein the mechanical dirt transfer mechanism is exterior to the dirt receptacle.
