We have many devices from Kärcher and had been totally satisfied, but this device is no good, at least for us. We bought it mainly to clean our bright tile joints, as well as general cleaning the window ect. The unit makes a good impression and is assembled quickly. Water clean, serviced short time and you can go. In the 1st fugue I was excited, super bright. But after the 2nd joint comes disenchantment. The machine has to heat up and has the time hardly perform. Say: The first super seconds, then the unit for about 15-20 seconds must heat up and is then fully operational for 10-15 seconds. So for us, unfortunately unusable because I will use for my Badfugen the whole day. The part has simply too little power. Wiping went quite well with the device, so even the 2 stars. However, we reserve the it not because we have the Clean-Maxx, which works the same. Conclusion: ect For wiping, washing windows. perhaps very well suited for cleaning right point however, not suitable as a lack of power is available, and it thus becomes the ordeal. Too Bad :(
