Karcher window vac reviews

What Is A Window Vacuum?

A window vacuum is a unique type of vacuum, which shares some interesting characteristics.

For instance, the vacuum is incredibly compact, lightweight and can usually be held in a single hand. 

Some of these vacuums can be attached to a rod, which gives you further reach.

These vacuums may also be equipped with a squeegee, which allows you to clean and vacuum the window at the same time.

What Can You Use A Karcher Window Vacuum For?

Although it is possible to utilize the Karcher Handheld Steam Cleaner for a wide array of purposes, its primary purpose is cleaning windows.

Due to the shape, size, and squeegee, the item is absolutely perfect for this purpose.

Of course, it is also reasonable to use one of these products, as a way to clean other areas of your home, including mirrors, tiles and shower enclosures. 

Most of these vacuums are capable of steaming the messy area, so they work well on reflective elements, which are normally difficult to clean.

It would also be possible to use to clean up small messes on your floor or furniture.

 Just remember that it cannot deliver the same efficiency as a bigger vacuum in this category.
