A cleaning system for cleaning a circular panel or any other circular surface is provided. The system has a base mechanically fastened to the circular panel. An axis stub pivotally connected to the base and attached to a pivot member provides rotation for a blade set. The blade set includes a first blade and a second blade configured to rotate independently about the pivot member in either a clockwise or a counter clockwise direction, wherein the second blade is configured to sit above the first bade, each blade having at least one row of sprinkler holes positioned on each side of the blade running lengthwise. The at least one row of sprinkler holes are configured to eject a fluid to either clean, cool, or thaw the circular panel. The first blade includes a roller having cleaning implements configured to clean the circular panel as the first blade rotates about the pivot member.

The present invention relates to an apparatus for cleaning a surface, in particular at solar collectors or photovoltaic installations. The apparatus has at least one cleaning head that comprises at least one cleaning member. The cleaning member is in particular a brush that can be set into rotation. The apparatus furthermore has a movement device for moving the cleaning head over at least a part of the surface to be cleaned. The movement device has a first movement unit movable in a first direction and a second movement unit. The cleaning head is movable transversely or obliquely to the first movement direction by means of the second movement unit along a guide means that is connected to the first movement unit. A control means that is arranged at the first and/or second movement units makes it possible to automatically move the first movement unit in dependence on a position of the second movement unit.

A cleaning system and method can include a leading carriage assembly attached to a brush assembly and can be configured to drive the brush assembly. A trailing carriage assembly can be configured to move along a track. The trailing carriage assembly can be attached to an arm. A vertical support rod can be partially disposed within the arm and can be attached to the brush assembly. A height of the vertical support rod can be positioned by one or more clamps located around the vertical support rod.
