## Abstract

A cordless, battery-powered system of cleaning products. The system of cleaning products includes devices such as upright vacuums (e.g., a stick vacuum, a lightweight upright vacuum, etc.), a hand-held vacuum, a carpet-cleaner, a canister vacuum, and the like. Each of the devices is powered by a battery pack which is interchangeable among the devices. The battery pack includes a combination of hardware and software for connecting to, identifying, and communicating with the cleaning products to ensure that each of the products receives the power necessary to ensure optimal performance.

## Claims

### Claim 1

A cordless upright vacuum cleaner, comprising:
a nozzle base portion having a suction inlet;
a body portion;
a pivotable joint coupled between the nozzle base portion and the body portion;
a suction source for providing a suction force at the suction inlet; and
a battery pack interface configured to receive a removable and rechargeable lithium-based battery pack,
wherein
the suction source is powered by the battery pack,
the body portion is pivotable relative to a first axis,
the body portion is pivotable relative to a second axis, and
the body portion is supportable by the nozzle base portion in a vertical position without external support.

### Claim 2 (depends on 1)

The vacuum cleaner of claim 1, wherein the combined weight of the vacuum cleaner and the battery pack is less than approximately seven and one-half pounds.

### Claim 3 (depends on 1)

The vacuum cleaner of claim 1, wherein the battery pack interface is a recess having a terminal contact portion, the recess configured to receive an extendable latch of the battery pack.

### Claim 4 (depends on 1)

The vacuum cleaner of claim 1, further comprising a fuel gauge external to the battery pack and configured to indicate a status of the battery pack.

### Claim 5 (depends on 1)

The vacuum cleaner of claim 1, wherein the first axis is parallel to a cleaning surface and the second axis is approximately perpendicular to the first axis.
