A window cleaner can save you a great deal of time, but not every product suits every home or car. A compact window squeegee is handy for mirrors and small windows, while a window-cleaning robot is particularly useful for large or hard-to-reach glass surfaces. A good glass cleaner and microfibre cloth also have a major impact on the final result.
When buying, do not focus only on terms such as “streak-free” or “powerful suction”. Above all, check the product specifications, intended surfaces and safety instructions. This will help you avoid buying a window cleaner that turns out to be impractical, fragile or unsuitable in everyday use.
Some automatic window cleaners mention a built-in battery. However, this battery is sometimes intended only as an emergency power supply in the event of a power cut. The window cleaner must then remain connected to the mains during use.
Therefore, check:
This is particularly important with a window-cleaning robot if you want to clean outside windows or windows at height.
A high pascal rating, such as 2,800 Pa or 5,500 Pa, tells you something about the stated suction power, but it is no substitute for safe use. A smooth, clean and undamaged pane is essential for a secure grip.
When using a robot window cleaner, always use the supplied safety line. Attach it to a sturdy anchor point indoors. Do not use a robot on cracked, loose, rough or porous surfaces. Stay nearby during use and follow the instructions.
A window squeegee can leave streaks if the rubber blade is damaged, dry or dirty. A microfibre cloth for glass is also less effective if it has previously been washed with fabric softener or contains a lot of dust.
For streak-free window cleaning, follow this order:
A window squeegee of around 20 cm is suitable for smaller windows, mirrors and shower screens. For larger panes, a 30 cm squeegee may be more efficient. An adjustable or telescopic handle is practical for high windows, but check that the locking mechanism feels sturdy enough.
A soft silicone or rubber blade is suitable for smooth glass, provided you remove coarse dirt first. Dry scraping can cause scratches if sand becomes trapped between the squeegee and the glass.
Pay attention to the size, structure and care instructions. The Dunlop Microfiber Cloth for Glass measures 35 x 35 cm and, according to the product information, is made from 100% viscose. The cloth is intended for glass and car windows and can be rinsed with warm or cold water and reused.
We recommend washing microfibre cloths without fabric softener. Also check whether the cloth leaves lint on dark car windows or mirrors.
A 750 ml glass-cleaning spray is practical for several cleaning sessions. Always check which surfaces the product can be used on. A product for windows and mirrors is not automatically suitable for untreated wood, natural stone or every type of plastic.

That depends on the model and the type of window. Check whether outdoor use is specified and whether it has a safety line, a sufficiently long cable and protection in the event of a power cut. Do not use the robot in the rain or on damaged glass if the instructions prohibit this. An outside window cleaner can be useful, but secure attachment remains essential.
First remove sand and loose dirt. Then use a small amount of glass cleaner and work with a clean window squeegee or microfibre cloth. Too much product can actually leave a film. Clean the squeegee blade after each stroke and dry the edges with a separate cloth.
In addition to the purchase price, running costs may include cleaning solution, microfibre cloths and replacement pads. A mains-powered model uses electricity while cleaning. Also check whether accessories such as safety lines and cloths are available separately. For a few windows a month, a manual window squeegee is often sufficient; with a large amount of glass, automation can make cleaning more convenient.
