What is the real search intent?
Users searching this term usually do not need a generic pressure washer. They need a PV-specific cleaning system that protects the panel coating and reduces yield loss.
Doka Engineering bridges the search terms “washing machine”, “cleaning robot” and “panel washing robot” naturally, while keeping product data limited to verified FK series specifications.
Why not a generic washer?
Robotic cleaning aims for controlled brush contact, repeatable movement and a safer operator workflow. On rooftop PV and larger PV plants, speed, safety and repeatability matter more than simply applying water.
The FK series can be configured for dry, wet or hybrid cleaning scenarios depending on panel layout, slope, access, water availability and cleaning frequency.
FK-1000 V3 or FK-600 V2?
FK-1000 V3 uses a 1000 mm brush and 1800 m²/hour capacity. It is the high-capacity, easily portable option for rooftop PV systems and larger PV installations.
FK-600 V2 uses a 600 mm brush and 1080 m²/hour capacity. It is the more compact option for rooftop PV, mid-scale sites and space-limited access.
FK-1000 V3
High-capacity, easily portable model for rooftop PV and larger PV sites.
FK-600 V2
More compact, easily portable model for rooftop, mid-scale and narrow-access PV sites.
How do price and quote become clear?
We do not publish generic fixed prices. The realistic price depends on panel count, site type, access, selected model, accessories, training and service scope.
For a useful quote, share panel count, installed power, location, rooftop/ground type, panel slope and water access.
FAQ
Is a solar panel washing machine the same as a cleaning robot?
In search language they are close. The correct Doka Engineering product category is solar panel cleaning robot: FK-1000 V3 and FK-600 V2.
Can I use a pressure washer?
Avoid high pressure or chemicals unless explicitly allowed by the panel manufacturer. Professional cleaning uses surface-safe brushes and controlled water.
Why is there no fixed price here?
Site type, panel count, model, accessories, training and service scope vary, so realistic pricing is given by quote; we do not publish generic fixed prices.
