    Features & Benefits


    Save energy and time: EASY!Force high-pressure guns and EASY!Lock quick-release locks.

    At last – work without getting tired: the EASY!Force high-pressure gun. EASY!Lock quick-release locks: durable and robust. And five times faster than screws.



    In the Eco setting the unit operates in the most economical temperature range (60°C) with full water flow. Burner cycles are optimised to reduce fuel consumption by up to 20% compared to full-load operation.


    Maximum efficiency

    Highly efficient burner technology. 4-pole, slow-running electric motor guarantees a long working time.


    Operational reliability

    The large, integrated fine-mesh water filter reliably protects the high-pressure pump against dirt particles. An integrated exhaust gas thermostat switches off the drive motor if the exhaust gas temperature exceeds 300°C. The soft damping system (SDS) compensates for vibrations and pressure surges in the high-pressure system.



    Integrated hose reel with 20m of high pressure hose.

    Roomy storage compartment for cleaning agents, gloves and tools.


    Mobility concept

    "Jogger" design with large rubber tyre wheels and swivel castors.

    Sturdy tie-down points for safe transit

    Integrated tilting aid for effortlessly negotiating obstacles such as steps and kerbs.
