Good pressure, but expensive) + also, my guess is that at the moment of switching the washing mode to rinsing, the foam turns on for 2-3 seconds and it will not work so quickly.Are they messing with the program or is it like that at the factory? At other car washes, such a question does not arise, foam was kicked out of the gun and clean water flows. Please note)
In general, a good sink that performs its main function - washing equipment. There are almost always a lot of cars in the evening and on Sunday. Sometimes it seems that the chemistry is not quite high-quality (the foam is too thin), failures rarely occur - foam arrives during rinsing. And in principle, it is quite possible to wash a car for yourself. I recommend.
The sink does not have a pause. The foam quality wants the best. I didn't even understand if there was foam or wax. The foam should work, i.e. you need to apply it and let it wait for a few minutes, but there is no way to put a pause. Because time is money
