Used the karcher to clean the car today for the first time. Plus points: lance is really light and easy to use. I was able to work round the car quickly on “hard” (ie rinse) mode. Significantly more wieldy than the commercial pressure washer down the road. Minus points. Detergent hose is too short and if you forget that you’ve put the end of it in a bottle, and move the karcher, you’ll tip the bottle over. Also, there’s not enough information (either with the product or online) about what sort of container for the detergent you should use (I think a square Tupperware container about 8cm high would work best: the hose is too short for anything taller) or how much you need to dilute a typical car shampoo by (I’m using two capfuls of autoglym shampoo per litre, which is enough to cover my car). Usage documentation is poor generally: there a video on utube about how to use this model, but it’s too short on details to be of much use. For instance, I had to look really hard online for advice about whether you should ever use the dirt buster lance on your car (pretty sure the answer is”no”, but I couldn’t find any authoritative source saying as much. Setup (fitting the high pressure hose) is also a bit fiddly. I’m thinking of leaving the hose permanently attached (at least during the summer) as I can see that being a significant time saver. Car cleaning performance looked good, though stubborn marks needed lots of close washing before they were removed. I wonder whether that’s fairly typical of pressure washers: not sure the commercial washer I used to use was much better. Now that I’ve worked details out by trial and error, I think I’ll use it regularly, at least for getting most of the dirt off. I’ll hand wash afterwards if I want it showroom clean.
