Professional brushes for cleaning photovoltaic panels and facades: the Mansser OSMO system
Effective cleaning of photovoltaic panels and facades calls for the right working tools. Every solar panel cleaning brush and facade cleaning brush in our range is designed for maximum effectiveness and for the safety of the cleaned surface. The Mansser OSMO range includes a complete set of professional brushes that, combined with our demineralised water machines and our facade cleaning chemistry and panel cleaning agents, form an integrated system that delivers excellent results.
Why does choosing the right brush matter so much?
Photovoltaic panels are precision devices whose surface needs particular care. Even minor scratches can reduce the output of a PV installation by as much as 30%. A properly chosen solar panel cleaning brush protects delicate anti-reflective coatings while still removing dirt effectively. Glass facades, aluminium fronts and painted surfaces likewise call for specialist tools. Our range of brushes is designed for versatility, from gentle cleaning of PV panels to intensive cleaning of heavily soiled industrial facades using professional facade cleaning agents.
Mansser OSMO nylon brushes: the foundation of professional cleaning
Nylon brushes are the most commonly chosen tools in professional cleaning, combining effectiveness with safety. Every panel brush in our range can also serve as a versatile facade cleaning brush. The Mansser OSMO system offers nylon brushes in three bristle hardnesses and three working widths, giving nine variants matched to specific needs.
Bristle hardness grades
SOFT nylon brush: dedicated to the most delicate surfaces, it is the ideal solar panel cleaning brush for panels with anti-reflective coatings and for high-grade insulated glass. Combined with demineralised water, it guarantees effective cleaning with no risk of scratching.
MEDIUM nylon brush: the most versatile panel brush, a perfect balance between cleaning power and safety. It is the variant most often chosen by professionals for the daily servicing of photovoltaic installations, cleaning glass facades and washing vehicles.
HARD nylon brush: a specialist facade cleaning brush for industrial areas that copes well with stubborn, dried-on dirt. Especially recommended for the first clean of badly neglected buildings.
Working widths
26 cm width: a compact panel cleaning brush for tight spaces, giving unmatched manoeuvrability. Ideal for cleaning details and hard-to-reach spots on photovoltaic installations.
36 cm width: the standard solar panel cleaning brush and the most commonly chosen size, offering an optimal balance between surface coverage and control. It delivers high productivity in everyday cleaning work.
46 cm width: a professional panel cleaning brush for large solar farms. The greater working width speeds up work considerably on extensive PV installations and on the facades of industrial buildings.

Brush sockets: precise angle adjustment
Brush sockets are an often underrated but important part of the cleaning system. The right socket lets you set the solar panel cleaning brush or the facade cleaning brush at the correct angle. The working angle affects both operator comfort and cleaning effectiveness. Mansser OSMO offers three socket variants.
90-degree brush socket: a standard solution that positions the panel brush perpendicular to the surface, ideal for horizontal surfaces such as photovoltaic panels on flat roofs or industrial floors.

45-degree brush socket: a specialist socket for the solar panel cleaning brush on panels mounted on sloping roofs, allowing work at a 45-degree angle and cleaning of angled facade elements.

All sockets are fully compatible with the rest of the Mansser OSMO system, ensuring a stable fit and effective demineralised water delivery.
Special brushes and pads: professional solutions for demanding jobs
Wool pad 20.5 cm
A specialist pad made of high-quality natural wool, designed for gentle cleaning and polishing of the most sensitive surfaces. It works excellently with demineralised water, absorbing and spreading the liquid evenly. Ideal as a complement to the solar panel cleaning brush for the final stage of cleaning panels with delicate anti-reflective coatings, and for polishing glass to a high shine. Compatible with Mansser OSMO joints and telescopic poles.
Boar bristle brush 36 cm
A professional brush fitted with natural boar bristles, a premium specialist tool in the Mansser OSMO system. The natural bristles are exceptionally hard yet flexible, which makes this facade cleaning brush ideal for removing the most stubborn dirt, including hard mineral deposits and scale. It is particularly recommended as a panel cleaning brush in locations with extreme operating conditions where standard brushes may fall short. Fully compatible with the Mansser OSMO system.

Frequently Asked Questions (FAQ)
Which nylon brush hardness should you choose for cleaning photovoltaic panels?
For regular cleaning of photovoltaic panels, a Soft or Medium brush works best. The Soft solar panel cleaning brush is ideal for panels with anti-reflective coatings and for routine cleaning. A Medium panel brush is a good choice when the dirt is a little heavier but the surface still needs care. Use Hard brushes only in exceptional situations, when dealing with badly neglected installations or very stubborn dirt. You will find detailed guidance in our article: Which solar panel cleaning brush should you choose?
Which nylon brush width should you choose?
The 26 cm width is ideal for working in tight spaces and cleaning details and hard-to-reach spots. The 36 cm width is the most versatile solar panel cleaning brush, suiting most standard jobs. The 46 cm width gives the highest productivity on large, open surfaces such as extensive solar farms or the facades of industrial buildings.
Are Mansser OSMO brushes compatible with other systems?
Our brushes are designed primarily for full compatibility with the Mansser OSMO system (telescopic poles, joints, photovoltaic panel washer). They have standard fittings that often also fit poles from other manufacturers with a compatible mount, but full functionality and the system warranty are guaranteed only within the complete Mansser OSMO system.
What are the different types of brush socket for?
The 90-degree socket is the standard for horizontal and near-horizontal surfaces. The 45-degree socket makes it easier to work on sloping surfaces such as PV panels on angled roofs. The 90-degree rotary socket gives maximum flexibility when cleaning complex surfaces and hard-to-reach spots, letting you change the angle smoothly during work.
When is a boar bristle brush a better choice than a nylon one?
A boar bristle brush is the choice for the most demanding jobs, when dealing with hard mineral deposits, scale or badly neglected surfaces where standard nylon brushes may not be enough. Natural boar bristles combine effectiveness with safety and are most often chosen by companies doing professional cleaning in difficult conditions.
Can I use Mansser OSMO brushes to wash vehicles?
Yes, Mansser OSMO nylon brushes work very well for washing all kinds of vehicles. A Medium panel brush in 36 or 46 cm width is an excellent choice for vans and passenger cars. For delicate paintwork we recommend a Soft panel brush. Combined with telescopic poles and demineralised water, you can wash vehicles without ladders, leaving no streaks on glass or bodywork.
How should you care for brushes so they last as long as possible?
After each use, rinse the brush thoroughly with clean water, removing all dirt residue and any detergents used. Store brushes bristle-up or hanging to avoid deforming the bristles. Avoid leaving brushes in direct sunlight for long periods. Regular care significantly extends a brush’s life and keeps its cleaning properties.
Can I use detergents with Mansser OSMO brushes?
Yes, our brushes are compatible with professional Mansser OSMO cleaning products. For cleaning photovoltaic panels we recommend Solar Clean, and as effective facade cleaning chemistry, Power Fasad and Clean Fasad work well. These facade cleaning agents were developed specifically to work with our facade cleaning brush and solar panel cleaning brush, ensuring optimal effectiveness without damaging the bristles. Always follow the product instructions.
How many square metres can I clean with one brush per day?
Output depends on many factors: the type of surface, the level of dirt, the operator’s experience and the system configuration. In standard photovoltaic panel cleaning, an experienced operator with a 36 cm panel brush and a complete Mansser OSMO photovoltaic panel washer can reach around 150 to 250 m2 per hour, which over an 8-hour day means up to 1200 to 2000 m2. A 46 cm brush can increase these figures by 20 to 30%.
