Karcher Window Cleaner

The fact that over three million Karcher Window Cleaners have been sold in the UK alone is evidence of how effective this domestic cleaning tool is. With a Karcher Window Vac, you can clean windows three times faster than before while guaranteeing that they will be streak, smear and drip-free. Karcher Window Vacs are operated by powerful Lithium-ion rechargeable batteries that can give you up to nearly two hours of cleaning time (depending on the model you choose), more than enough for even the largest of homes.
Karcher is a family-owned company based in Winnenden, Germany. It is a world leader in cleaning and decontamination technology with operations in 160 countries including the UK. The Vac window cleaner developed out of the technology used in Karcher high-pressure cleaners designed for cleaning outdoor surfaces and brickwork.

For the best results, use the brand's own glass cleaner. It ensures streak and grime-free windows every time. As it is concentrated, only a small amount is needed making it economical to use. Available in 500ml bottles or packs of 4 x 20ml sachets. (Some models come with a small bottle of cleaner concentrate.)

(Included with some models.) Spray your cleaning liquid exactly where needed with this premium spray bottle and use the microfibre cloth, wide and narrow wipers and dirt scraper to ensure you always have gleaming windows. The kit also includes 20ml of glass cleaning concentrate.

Use the hook-and-loop system to attach one of these to a dirt scraper for optimal dirt removal. Once the job is finished, the cloths can go in the washing machine.

Sometimes battery chargers have a habit of going missing. If so, this is a suitable replacement. With the exception of the Window Vac 6, it is compatible with all Karcher Window Cleaners.
