According to product review, Karcher window cleaning tools are an opinion divider.
Take, for instance, the WV 50 Plus. Out of 71 reviews at the time of printing, there were 42 excellent reviews and 13 Terrible reviews. This shows the problem with these products. For the easy to please, these items will be the answer to their dreams, for the difficult to please these items will be nothing more than a gimmick. Why is this?
It all comes down to focus. What exactly do you want the item to achieve? If it is to touch up a generally clean window, on ground level,with no scrubbing required, then this item will likely do the job you require. However, reality says that most people clean their windows because they're dirty. They are not generally once a week or month cleaners, rather, once a year cleaners. In this scenario, the built on, burnt on dirt may not be as easily shifted. Reality also dictates that windows are not often reachable by a handheld unit but, require extension poles or ladders to reach.
So, there is no doubt that if your windows require a quick touch-up then the steam cleaners will do the job adequately, however, if your windows are truly dirty, then hiring a professional company such as Housewindowcleaning is a must.
Therefore, value for money depends upon how exactly you intend to use the unit. It will save you both time and money to sit down with a hot cuppa for enough time to cut the emotion out of your reasoning and decide if you will truly use the unit in a way that will save you money, or, whether it will be an impulse purchase that will be returned as soon as 1 or 2 fruitless efforts have caused you to lose all hope.
Handheld steam window cleaners have a place but is that in your home? We'll let you decide.....
