I have received the cleaning gun 5 days ago. The delivery was fast and the product was well packaged. First of all I worked so our doormat at the front door with the device. So to speak as a "worst case". The 3 years old and soiled wipers entspechend was afterwards as new. Meanwhile, I've also cleaned the beige carpets in my car. The result is convincing. I would buy the device immediately.
Disadvantage: The Druckluftanschlüss goes vertically downwards. This means that at half-full container cleaning the gun through the air hose can no longer be safely parked. She tilts like to side, which interferes with work, because you're always trying to find a suitable Abstellort for the gun. An angled compressed air connection would be beneficial here. Therefore deduction of points.
