Cleaning solution for ground-mounted solar power plants

WetSlider XL - PV cleaning robot

The best solution for water-based cleaning of solar panels at ground-mounted stations

Our robot is the fruit of many years of research and development. It has been developed using the latest technologies and innovative materials, giving it optimum performance. Attentive to the operating constraints of solar power plant operators, AX SOLAR ROBOT develops easy-to-use, highly efficient photovoltaic panel cleaning solutions.

Based on developments to the WetSlider, the WetSlider XL adapts to both table size and module size, enabling it to be used on a wide range of ground-mounted, fixed or tracker-mounted power plants.

A host of advantages!

"The Swiss Army knife"

The “WetSlider XL” adapts to multiple PV table configurations, using the same technology and brush length whatever the site. While the WetSlider is dedicated to the cleaning of 1P tracker PV power plants, its “XL” version offers additional adaptability, enabling the cleaning of tables up to +6.5m in length, while being adjustable to any site, which also simplifies logistical considerations compared with vehicle-mounted systems, for example.

How is this achieved? Its patent-pending architecture provides vertical translation capability for the brush system along the tables, while retaining all the advantages of the original robot (adaptation of module size, parallel operation on a single pump, cleaning efficiency, obstacle management, avoidance of ground degradation).

This is why the “WetSlider XL” can definitely be called the “Swiss Army knife” of any PV floor cleaner!

How does the cleaning robot work?

Each row of panels is cleaned in two successive rounds. At the end of the cycle, the robot automatically positions itself on the rolling support, which then allows it to be placed in front of the next row. Two operators are required to control the robot. No robot handling is required.

Thanks to our unique technology, our robot is also the fastest and most water efficient.

Support systems for WetSlider robots


When no electricity or water supply is readily available, this trailer is the solution. It comes with a polyethylene water tank from 2 000 to 3 000 liters and a high pressure diesel pump. This can be towed between the plant aisles by any car. Other tank capacities are available upon request.


Pompe diesel haute pression

Our cleaning robots are powered by a high-pressure water pump that provides the necessary flow for cleaning and moving.
With our high pressure diesel pump, no electrical connection is required. The pump is 100% self-contained and simply needs to be connected to the low pressure water. Electric drive pumps are also available upon request.
