Choosing a pressure washer flat surface cleaner

Flat surface cleaners use a rotating spray bar beneath a covered cleaning head to work across hard surfaces more evenly than a standard lance. The right model depends on the surface being cleaned, the working width you want and, most importantly, the pressure, flow and connection setup of your pressure washer.

12″ Turbo Devil flat surface cleaner

The 12″ Turbo Devil Flat Surface Cleaner is a compact stainless-steel option with an adjustable swivel. It is rated to a maximum of 250 bar, 30 LPM and 90°C, with an M22 male inlet. It can also be combined with compatible GVS Pressure Poles for suitable high-level cleaning setups.

12″ Mosmatic surface cleaner

The 12″ Mosmatic Surface Cleaner is a stainless-steel model rated to 275 bar. Its toggle swivel allows the head angle to be adjusted for suitable ground, wall and roof-cleaning applications, and the cleaner can be used with compatible hot-water pressure-washing setups.

Whirlaway 14″, 16″, 18″ and 20″ surface cleaners

The Whirlaway range provides a choice of working widths for patios, driveways and concrete flooring. The 14″ Whirlaway is rated for 12–30 LPM and 150–276 bar, with a maximum temperature of 85°C. An M22-to-Mini-Quick-Release option is available where required for compatible GVS Pressure Pole setups.

The 16″, 18″ and 20″ Whirlaway models are rated for 12–30 LPM and 150–276 bar, with a maximum temperature of 80°C. These models are supplied with trigger gun and nozzles, while the 18″ and 20″ cleaners also use four castor wheels.

Match the cleaner to your pressure washer

Do not choose a surface cleaner on diameter alone. Check the cleaner’s working-pressure range, flow requirement, temperature rating, inlet connection and nozzle setup against the machine you intend to use. The GVS flat surface cleaner range is suitable for compatible GVS Tsunami pressure washer setups, but connection requirements vary between models.

For wider system-selection guidance, see our pressure washing equipment buying guide, or contact GVS if you need help checking a cleaner against your existing pressure washer, hose or fitting setup.
