Bypass type cleaning apparatus

1. A bypass type cleaning apparatus comprising:

a suction nozzle, the suction nozzle including a rotating brush rotatably disposed at a contaminant suction port of the suction nozzle;

an air suction unit being in fluid communication with the suction nozzle via an entering passage; and

at least two contaminant collecting receptacles being in fluid communication with at least two exits formed at the air suction unit, respectively.

2. The bypass type cleaning apparatus of claim 1 , wherein

the entering passage is disposed at a center of the air suction unit.

3. The bypass type cleaning apparatus of claim 1 , wherein

the at least two contaminant collecting receptacles are arranged to be symmetric with each other at both sides of the air suction unit.

4. The bypass type cleaning apparatus of claim 1 , wherein the air suction unit includes:

a housing connected with the entering passage, and having the at least two exits;

an impeller disposed inside the housing; and

an impeller motor disposed outside the housing, and causing the impeller to rotate.

5. The bypass type cleaning apparatus of claim 1 , wherein

the rotating brush is caused to rotate by a brush motor disposed underneath one of the at least two contaminant collecting receptacles.

6. The bypass type cleaning apparatus of claim 1 , wherein

each of the at least two contaminant collecting receptacles includes a filter.

7. The bypass type cleaning apparatus of claim 4 , wherein the impeller includes:

a rotating plate connected to a rotating shaft of the impeller motor; and

a plurality of blades disposed on the rotating plate.

8. The bypass type cleaning apparatus of claim 7 , wherein

the plurality of blades comprises 4 to 6 blades.

9. The bypass type cleaning apparatus of claim 7 , wherein

each of the plurality of blades is formed in a shape selected from a group of an airfoil, a flipped end shape, and a circular tip shape.

10. A bypass type cleaning apparatus comprising:

a suction nozzle;

an air suction unit disposed at one side of the suction nozzle, and being in communication with the suction nozzle via an entering passage, the air suction unit including:

a housing having an entrance connected with the entering passage, and first and second exits connected with each of the first and second contaminant collecting receptacles,

an impeller disposed inside the housing, and

an impeller motor disposed outside the housing, and causing the impeller to rotate; and

first and second contaminant collecting receptacles disposed at both sides of the air suction unit, and being in fluid communication with the air suction unit.

11. The bypass type cleaning apparatus of claim 10 , wherein

the entrance of the housing is formed at a center of a front surface of the housing.

12. The bypass type cleaning apparatus of claim 10 , wherein

the first and second exits of the housing are formed at both side surfaces of the housing.

13. The bypass type cleaning apparatus of claim 10 , wherein

the suction nozzle includes a rotating brush rotatably disposed at a contaminant suction port of the suction nozzle.

14. The bypass type cleaning apparatus of claim 13 , wherein

the routing brush is configured to rotate by a brush motor disposed underneath one of the first and second contaminant collecting receptacles.

15. The bypass type cleaning apparatus of claim 10 , wherein the impeller includes;

a rotating plate connected to a rotating shaft of the impeller motor; and

a plurality of blades disposed on the rotating plate.

16. The bypass type cleaning apparatus of claim 15 , wherein

each of the plurality of blades is formed in a shape selected from a group of an airfoil, a flipped end shape, and a circular tip shape.
