To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I got two Karchers, one for myself and one for my daughter. I have not used mine yet, I am waiting to do a big spring clean in a week or so, but my daughter is pleased with her one. However, there are a couple of things she thought could be improved. The cord is too short, you need an extension cord to move from place to place. There should be two mop bases not one. Other than that she was pretty happy with it.
