Product glad because I did not think to buy the brand karcher but an imitation! That's the original product I paid 8 euros and bananas plus delivery Amazon Prime! When you buy the steam mop is received as a brush: it does not go away with that! The brush abyss fast enough and we can not use it and the bathroom and the kitchen not very hygienic! There are 2 black and 2 red to differentiate 4 color .Why not? Super useful for cleaning difficult and very dirty parts: shower joints, cooking hobs! We can superimpose over the brushes kitchen metal sponges (I cut)! It helps to clean even a little better and protects the brush. very satisfied with my purchase
