The dirty water container is larger than previous models. It can hold 150mls of dirty water, which is a 50% increase. This allows you to clean for longer without having to empty the machine.

The Karcher Anniversary Edition window vacuum has a rechargeable Lithium-Ion battery with a run time of 35 minutes. This allows you to clean up to 105m² of glass, which equals around 35 windows. Depending on the size of your home, it should last weeks before needing to be recharged.

The WV5 Premium has a Lithium-ion battery that has a 35 minute run time, and it can be fully recharged from flat in 185 minutes. The interchangeable suction heads, 100ml dirty water capacity and LED battery indicator ensure your windows will be sparkling with a minimum of fuss.

Features of the Karcher WV5 Premium Window Vacuum

The Karcher WV5 Premium has a removable battery, so although the 35 minute run time will allow you to clean up to 35 windows, you can always have a spare battery charged so your window cleaning is not interrupted.  There is also a handy 3-stage LED battery indicator so you always know how much cleaning time you have left.

The interchangeable cleaning heads come in two sizes, 170mm and 280mm, so you can clean any size of window and be confident of getting right into the edges. The manually adjustable edge guidance system really helps with edge cleaning and means you can clean hard to reach areas such as shower screens, car windows and tiles.
