High-performance flushing systems – improved cleanliness and road safety
Efficient street cleaning and maximum road safety thanks to innovative high-pressure flushing technology.
Challenging contamination caused by bad weather, construction site vehicles or daily traffic requires high-performance solutions. Fiedler Maschinenbau’s flushing technology sets new standards in professional surface cleaning. Our systems are specially designed to effectively remove mud, dust and coarse dirt from roadways and public spaces using high pressure, and to transport it away in a targeted manner.
Why choose Fiedler flushing technology?
Our modular solutions – from fan nozzles (frog-mouth nozzles) and jet pipes to flushing booms (telescopic or with sliding mechanism) – are characterised by maximum flexibility and user-friendliness. Whether narrow-track vehicles such as the Egholm or Kärcher, light trucks such as the Multicar or Hansa, or heavy-duty truck chassis such as MAN or the Unimog: our technology can be precisely adapted to any carrier vehicle.
Your benefits at a glance:
Maximum cleaning performance: Powerful high-pressure flushing nozzles for residue-free cleanliness in demanding, continuous municipal use.
Customisation: Flushing booms (telescopic or with sliding mechanism) and adjustable nozzles for any required width.
Intuitive operation: Convenient control and pressure regulation directly from the driver’s cab for efficient work processes.
Ensure clean pavements and safe roads – put your trust in the expertise of Fiedler Maschinenbau, your partner for innovative municipal technology.

** FMC / *** FMC and EASY Control are essential
In modern municipal technology, maximum efficiency, resource conservation and ergonomics are key to operational success. This is precisely where the FIEDLER Multimatic-Control (FMC) comes into its own.
Thanks to intuitive operation via a proportional joystick or a 3D mouse, drivers retain full control. Water volume, nozzle configuration and working width can be controlled directly from the cab. Whether on narrow pavements or wide main roads – the working width of the flushing boom can be flexibly adjusted. The result: a consistently perfect flushing pattern, both when cornering slowly and when cleaning at speed on straight stretches.
Technical highlights at a glance:
- Water volume and pressure: Intuitive regulation of flow rate and optional display of the water volume applied.
- Stepless width adjustment: Millimetre-precise control of the hydraulic telescoping mechanism or the award-winning chain-driven adjustment of the flushing boom.
- Section shut-off: Section control (centre section/side sections) saves water on narrow lanes.
- Special nozzle management: On-demand activation of frog-mouth nozzles, vertical spray bars or high-pressure under-floor nozzles to tackle stubborn dirt.


The Fiedler single-tank strategy –
Systematic year-round use
Maximise the profitability of your fleet. With the FTS tank system (AllSeason-FlexiTank), you can use your carrier vehicle 365 days a year:
- Summer use: Ideal for watering, flushing and high-pressure cleaning. Optionally expandable as a hot-water system for chemical-free weed control.
- Winter use: In just a few simple steps, you can convert the system into a highly efficient brine spray system for winter maintenance.
Invest in sustainability and efficiency. Fiedler spray booms are the robust solution to the challenges of modern urban and landscape maintenance.
