Comet KM Classic and Extra 3.11
The Comet KM 3.11 available in the Classic and Extra variants with and without water tray and anti-limescale tank, is a professional hot water pressure washer with a 2.2 kW single-phase 4-pole motor which, thanks to the high outlet water temperature ( 110°) is ideal for removing stubborn and water-insoluble dirt.

This great advantage compared to cold water pressure washers means that the Comet KM 3.11 is used in the most varied sectors such as agrotechnical, food, industrial and construction and constitutes an excellent solution for cleaning machinery, machine tools, engines and means of transport (often covered in oily dirt).


It is used in the food industry to clean and remove animal or vegetable residues, in the cleaning of stables but also of building equipment, etc.
There are many advantages deriving from the use of the Comet KM 3.11 including a shorter washing time thanks to the cleaning power of hot water, a shorter drying time of the washed parts, a deeper cleaning of water-insoluble dirt , a use of detergent and therefore lower fixed cleaning costs.


The Comet KM 3.11 is available in the Comet KM Classic 3.11 and Comet KM Extra 3.11 variants, in turn with and without water tray and anti-limescale tank .
The hull of Comet KM Classes has a liftable lid.
