The jet does very well what it is designed; after brushing, you still manage to dislodge dirt remained stuck and not achievable by brush. So great result.
For now, I do not have to exceed the level 3 power to achieve this.
the only drawback for me for now: the water flowing down my forearm which holds the jet; Perhaps this is always like that, or maybe just because I'm in the wrong way (my husband made the same observation, however).
In short, the overall balance, I recommend this purchase and also Amazon is really a sign top.
