Abstract

A cleaning system including a motor, an impeller driven by the 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 one of a first type of data and a second type of data, and operate the motor at a defined speed, the defined speed being a first speed upon receiving the first type of data, and a second speed upon receiving the second type of data.

First claim

What is claimed is:

1. A cleaning system comprising:
a motor;
an impeller driven by the 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 battery capacity and a second signal indicative of a second battery capacity, 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.

2. The cleaning system of claim 1 , wherein the battery receptacle is configured to receive one 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 a second-motor.

5. The cleaning system of claim 4 , 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.

6. The cleaning system of claim 5 , 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.

7. The cleaning system of claim 4 , wherein the second-motor drives a brush-roll.

8. A method of operating a cleaning system, the method comprising:
receiving a first battery pack including a first battery controller;
receiving a first signal indicative of a first battery capacity from the first battery controller;
outputting a first control signal based on receiving the first signal;
operating a motor at a first speed based on the first control signal;
receiving a second battery pack including a second battery controller;
receiving a second signal indicative of a second battery capacity from the second battery controller;
outputting a second control signal based on receiving the second signal; and
operating the motor at a second speed based on the second control signal.

9. The method of claim 8 , further comprising
operating a second-motor at the first speed based on the first control signal; and
operating the second-motor at the second speed based on the second control signal.

10. The method of claim 8 , wherein the motor drives one selected from the group of an impeller and a brush-roll.

11. A cleaning system comprising:
a motor;
an impeller driven by the 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 battery capacity from the first battery pack and a second signal indicative of a second battery capacity 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.

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

13. The cleaning system of claim 12 , wherein the second-motor is operated at a second defined speed, the second defined speed is
a first speed when the motor controller receives the first signal, and
a second speed when the motor controller receives the second signal.

14. The cleaning system of claim 12 , wherein the second-motor drives a brush-roll.
