## Abstract

A cleaning device for cleaning vertical pipes includes a cylindrical section, a bottom plate and an upper plate having a cable attachment means, an internal weight, and at least one wiper disk, the device defining a fluid flow path through or around the device.

## Claims

### Claim 1

A cleaning device, comprising at least one cylindrical section, a bottom plate and an upper plate having a cable attachment means, an internal weight, and at least one wiper disk, the device defining a fluid flow path through or around the device.

### Claim 2 (depends on 1)

The device of claim 1 comprising:
(a) a plurality of stacked cylindrical sections, joined by attachment flanges; and
(b) a plurality of wiper disks, disposed between attachment flanges of adjacent stacked cylindrical sections.

### Claim 3 (depends on 1)

The device of claim 1 wherein the internal weight comprises two or more cylindrical weights, concentrically disposed within the at least one cylindrical section and each other.

### Claim 4 (depends on 1)

The device of claim 1 wherein the at least one wiper disk comprises a flexibly resilient material.

### Claim 5 (depends on 1)

The device of claim 1 comprising at least two wiper disks, which have the same or different diameter.

### Claim 6

A kit for cleaning a substantially vertical pipe, comprising:
(a) a cleaning device having a first circular wiper disk; and
(b) at least one additional circular wiper disk having a different diameter than the first circular wiper disk.

### Claim 7 (depends on 6)

The kit of claim 6 wherein the cleaning device further includes a first internal weight, the kit comprising at least one additional weight for adding weight to the cleaning device.

### Claim 8 (depends on 6)

The kit of claim 6 wherein the cleaning device comprises a plurality of wiper disks, and the at least one additional circular wiper disk comprises a plurality of additional wiper disks having at least two different sizes.

### Claim 9 (depends on 7)

The kit of claim 7 wherein the first internal weight and the at least one additional weight is cylindrical, sized to concentrically nest within the cleaning device and/or each other.
