Abstract

A cleaning system including a motor, a battery receptacle, and a motor controller. The battery receptacle is configured to receive a battery pack. The battery pack includes one or more battery cells and a battery controller. The motor controller is configured to receive from the battery controller at least one selected from the group consisting of a first signal indicative of a first characteristic of the battery pack and a second signal indicative of a second characteristic of the battery pack. The motor controller is further configured to operate the motor at a defined speed, the defined speed being a first speed upon receiving the first signal and a second speed upon receiving the second signal. Wherein the first characteristic and the second characteristic are at least one selected from the group consisting of a capacity, a current, and a resistance.

Claims

1. A cleaning system comprising:

a motor;

a battery receptacle configured to receive a battery pack, the battery pack including one or more battery cells and a battery controller; and

a motor controller configured to

receive from the battery controller at least one selected from the group consisting of a first signal indicative of a first characteristic of the battery pack and a second signal indicative of a second characteristic of the battery pack, and

operate the motor at a defined speed, the defined speed being

a first speed upon receiving the first signal, and

a second speed upon receiving the second signal;

wherein the first characteristic and the second characteristic are at least one selected from the group consisting of a capacity, a current, and a resistance.

2. The cleaning system of claim 1, wherein the battery receptacle is configured to receive at least one selected from the group consisting of the battery pack and a second battery pack.

3. The cleaning system of claim 2, wherein the motor controller receives the first signal from the battery controller of the battery pack and the second signal from a second battery controller of the second battery pack.

4. The cleaning system of claim 1, further comprising an impeller driven by the motor.

5. The cleaning system of claim 1, further comprising a brush-roll driven by the motor.

6. The cleaning system of claim 1, further comprising a second-motor.

7. The cleaning system of claim 6, wherein the second-motor is operated at a second defined speed based on receiving at least one selected from the group consisting the first signal and the second signal.

8. The cleaning system of claim 7, wherein the second defined speed is

a first second-motor speed when the motor controller receives the first signal, and

a second second-motor speed when the motor controller receives the second signal.

9. The cleaning system of claim 6, wherein the second-motor drives a brush-roll.

10. The cleaning system of claim 6, wherein the second-motor drives an impeller.

11. A cleaning system comprising:

a motor;

a battery receptacle configured to receive a first battery pack and a second battery pack; and

a controller configured to

receive a first signal indicative of a first characteristic from the first battery pack and a second signal indicative of a second characteristic from the second battery pack, and

operate the motor at a defined speed, the defined speed being

a first speed based on the first signal, and

a second speed based on the second signal;

wherein the first characteristic and the second characteristic relate to at least one selected from the group consisting of a capacity, a current, and a resistance.

12. The cleaning system of claim 11, wherein the battery receptacle is configured to receive at least one selected from the group consisting of the battery pack and a second battery pack.

13. The cleaning system of claim 12, wherein the controller receives the first signal from the first battery pack and the second signal from the second battery pack.

14. The cleaning system of claim 11, further comprising an impeller driven by the motor.

15. The cleaning system of claim 11, further comprising a brush-roll driven by the motor.

16. The cleaning system of claim 11, further comprising a second-motor.

17. The cleaning system of claim 16, wherein the second-motor is operated at a second defined speed based on receiving at least one selected from the group consisting the first signal and the second signal.

18. The cleaning system of claim 17, wherein the second defined speed is

a first second-motor speed when the controller receives the first signal, and

a second second-motor speed when the controller receives the second signal.

19. The cleaning system of claim 16, wherein the second-motor drives a brush-roll.

20. The cleaning system of claim 16, wherein the second-motor drives an impeller.
