Carpet Cleaning Questions

The Comet is a new low cost, self-contained carpet extraction cleaner with powerful brush agitation to clean carpets. It weighs only 18 kilos so it's light enough for anyone to handle, plus the compact body design and fold-down handle make it easy to transport and store. Remove two safety screws and the machine opens like a clamshell for fast service. The Comet is small enough to clean in tight spaces and corners yet powerful enough to perform well in any situation. A revolutionary bladder design eliminates the need to pour solution into the machine. Simply fill the bucket, set it on the machine, close the lid and begin cleaning.

No more spills or mess! The one on-off switch is designed for operation simplicity.

  • Patented lift-off bucket makes filling and emptying easy and convenient.
  • See-through recovery dome.

Comet Parts Diagram


Although the use of a recognised Defoamer product is mentioned in all the service manuals issued with new machines the End User will hardly ever read this part and therefore will not use the product.

The emphasis placed on a recognised Defoamer product cannot be stressed enough.

Use of Defoamer in the recovery tank of a machine will, in most cases prevent excess water damage to vacuum motors due to dirty water ingestion. This is caused by the fact that foam is lighter than water and will not close the vacuum shut off ball cage assembly. This, in turn will lead to the foam being ingested into the vacuum motors.

In addition to this, it is also important to your keep clean water reservoir separate from waste water and to this end we also recommend the use of different coloured buckets such as the red and white Prochem CN3503 buckets shown at the bottom of the page, the red being used solely for waste water and the white just for clean.

Any vacuum motor returned for repair or warranty claim that shows any sign of dirty water ingestion will not be replaced since the Terms & Conditions of Warranty have not been adhered to.

Directions for use of defoamer.

Add 20ml of Prochem S760 Liquid Defoamer concentrate per 10 litres of recovery tank capacity (1-500).

Dilute the required amount of concentrate in a small amount of water and feed this solution into the vacuum hose, with the machine switched on and add defoamer solution directly to the machine recovery tank.

Do not add Defoamer to the cleaning solution.

For excessive foam, increase the amount of S760 required.
