Who high-pressure jet from the gas station to clean the wheel appear to be dangerous (the pressure could damage sensitive parts) is well served with this unit.
For me it was all about, if possible at reduced expense to clean my normal Treckingrad which I use daily almost exclusively in big cities and wetterunabängig and so downright filthy over time - and with stubborn dirt, mixed with any greasy deposits.
For device itself:
For the price in my opinion without competition (other devices I tried ...). The sprayer is including all the fittings are very light with about 1.5 kilograms, the assembly is well described simply and in the instructions. I can not say anything about the long-term functionality, however, make the thread at the main tank a pretty thin-skinned impression when bolting the components you need to quite careful to ensure everything is just. To get the device ready for operation, you have to only the nozzle using the supplied hose to connect, screw this and the pressure relief valve on the main tank.
Then it is pumping until there is sufficient pressure. This requires little physical strength. When you reach the 3 bar, you can hear the relief valve work (albeit rather low). The fixed after the pressure build-up pump can be used as a carrying handle, practical. Then you can get started.
The somewhat by sight viewing strip is mounted on the container far apart from the actual scale, this is also pressed, not printed, and thus difficult to detect. This could be improved ...
The curved end brass nozzle is adjustable due to the length of the interaction with the rather long connecting hose extremely practical and manoeuvrable and with restrictions in terms of spray starch on the nozzle. The scope here is not too big, the rough moistening up to a hard beam have to have a bit of tact.
For my purpose:
The sprayer is of course not useful as the sole detergent, but in combination with fat / chain cleaner and manual scrubbing a great help. The pressure is not too powerful, but powerful enough to remove with warm water (possibly mixed with classic dishwashing) debris or the wheel to inject clean.
My chain and pinion I have previously cleaned with for the intended cleaners, especially on soiled areas (except tires and brake linings) I have them still up doing something. After exposure to the sprayer with warm water and washing-up liquid was used, but not only there, but also on the rim, the frame, etc. After that nachgesäubert manually and even sprayed with a Gloria charge pure water.
My bike looks almost like new and everything works smooth ... In the volume of 3 liters of the unit I had to refill for a complete bike cleaning it twice.
