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.

First claim

What is claimed is:

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.
