The new **COMET K STEEL TS** has been designed to combine professional performance, a robust structure and easy manoeuvrability in a machine built to handle the most demanding cleaning applications. The new range replaces the previous K Steel S and TS models, bringing together the key advantages of both: **compactness, performance, advanced electronics and operational flexibility in a single model**. The new range includes several electrically powered versions, offering maximum pressures of up to **230 bar** and water flow rates of up to **1,260 l/h**, depending on the model. COMET pumps feature three solid ceramic pistons and a brass pump head. The K Steel range also features seals suitable for use with **hot inlet water at temperatures of up to 85°C**, except for the 10.21 model, which has a liquid-cooled motor and a maximum inlet water temperature of **50°C**. [Discover the New K-STEEL TS - Download Data-Sheet](https://blog.comet-spa.com/hubfs/NEW%20K%20STEEL%20TS-DATASHEET-EN.pdf)   ## **An ideal solution for intensive professional cleaning** K STEEL TS has been designed for professionals who use pressure washers frequently and need a reliable, easy-to-handle machine, even under the most demanding working conditions. Its compact frame features a **stainless-steel cover**, while the large **300 mm wheels** make it easier to move the machine over steps and uneven ground. The design also provides easy access to the motor-pump unit and electronic control panel by simply removing the cover, making inspection and maintenance operations easier. The result is a professional pressure washer that combines **durability, mobility and heavy-duty performance** without the need for an excessively bulky structure. ![K STEEL TS - Cold water pressure washer for intensive professional use](https://blog.comet-spa.com/hs-fs/hubfs/K%20steel%20punti%20forti%20EN.jpg?width=1024&height=526&name=K%20steel%20punti%20forti%20EN.jpg) ## **Why choose a cold water pressure washer that can operate with hot inlet water?** In professional cleaning applications, pressure is not the only factor that matters. When the type of dirt and the cleaning process require high-temperature inlet water — for example, on farms that use preheated water for its greater sanitising effectiveness — it is essential that the pump and its components are designed to operate under these conditions. K STEEL TS models equipped with **ZW and FW2 pumps** **feature hot water seals and a professional flanged pressure regulating valve.** The range also uses **self-priming pumps**, a particularly useful feature in professional applications where flexibility and operational continuity are essential, especially when **water is drawn from external tanks.** However, it is important to distinguish K STEEL TS from a hot water pressure washer: **the machine does not heat the water itself**. [Looking for a hot-water pressure washer? Discover the Comet range – a wide selection of professional models.](https://comet-cleaning.com/en/pressure-washers/hot-water)   ## **Where can K-STEEL TS be used?** Thanks to its different pressure and flow rate configurations, K STEEL TS is suitable for a wide range of professional cleaning applications. ### **Agriculture** On farms, livestock facilities and agricultural work sites, K STEEL TS is an ideal solution for **cleaning stables, floors, vehicles and work equipment**. Different combinations of pressure and flow rate make it possible to select the most suitable machine for dirt removal and equipment cleaning requirements. ### **Automotive and Transport** K STEEL TS is also suitable for **washing cars, commercial vehicles, trucks and heavy-duty vehicles**, as well as cleaning the equipment used in these sectors. Where large vehicles are washed frequently, a high-water flow rate can help speed up rinsing and cleaning operations on extensive surfaces. ### **Construction** On construction sites and in professional maintenance operations, the pressure washer can be used for **cleaning machinery and equipment** and removing residues such as concrete, cement, plaster and render. In these applications, the most important factors include structural durability, available pressure and the ability to operate the machine continuously.

The ideal configuration therefore depends on the type of dirt, the surface to be cleaned and how frequently the machine will be used.

The machine features an **oversized, paint-protected 4-pole motor operating at 1,400 rpm**. Models 9.15 and 9.21 also incorporate a dedicated pump-motor coupling system designed for intensive use. The 10.21 model, on the other hand, features a **water-cooled electric motor with a flexible coupling**. ## **Advanced electronic control system** K STEEL TS features an advanced electronic system designed to optimise machine operation and detect potential problems, allowing operators to take timely action before more serious and costly damage occurs to the main components. The **Delayed Total Stop system**, **micro-leak detection with automatic shutdown, routine pump maintenance alerts and water shortage warnings** all contribute to effective machine management during professional cleaning operations. ## **Easy handling and simplified maintenance** A professional pressure washer must deliver powerful performance while remaining practical for everyday use. K STEEL TS features **300 mm wheels**, designed to make the machine easier to move over steps and uneven surfaces, together with an anti-vibration foot that helps improve stability during operation. The inlet filter is easily accessible for inspection, while the pump oil level can be checked from outside the machine. Access to the motor-pump unit and electronic control panel has also been designed to simplify maintenance operations. The control panel incorporates a rotary On/Off switch and the machine's monitoring and warning systems. ## **Professional standard equipment and accessories for different applications** Depending on model compatibility, the standard equipment includes a **professional spray gun, stainless steel angled lance, flat-jet nozzle, 10-metre reinforced rubber high-pressure hose with metal reinforcement, and a professional foam lance with regulator**. A comprehensive range of accessories also allows K STEEL TS to be configured for more specialised cleaning applications, including: - Rotary nozzle lances - Pipe cleaning hoses - Sandblasting or bicarbonate cleaning kits - Double-barrel lances - High-pressure hose extensions - Hose reels ## **K-STEEL TS at a glance**   K STEEL TS is designed for professionals looking for a pressure washer that offers: - **Compact dimensions and easy manoeuvrability** - **Robust stainless steel construction** - **Suitability for intensive professional use** - **Maximum pressure ranging from 130 to 230 bar** - **Water flow rates of up to 1,260 l/h** - **COMET pumps with three solid ceramic pistons and brass pump heads** - **Configurations suitable for operation with hot inlet water** - **Electronic systems for micro-leak detection, maintenance monitoring and water shortage alerts** The different configurations make it possible to find the right balance between **pressure, water flow rate, electrical power supply and intensity of use**, selecting the machine according to the specific cleaning task. ## **FAQ about K-STEEL TS and compact professional pressure washers** ### **Is K STEEL TS a hot water pressure washer?** K STEEL TS features pumps and seals suitable for use with hot water on the specified models.
