I find that my mains powered washer gives too much pressure and I get dirt flying everywhere where I don't want it and it also hurts delicate surfaces. However, a garden hose gives to little pressure and that is why I got this washer. I find it perfect for that in-between use. There are room for some improvements, it is direct drive so as the battery sags in voltage the pressure drops noticeably, you probably get decent pressure for 50% - 70% of the battery capacity. I find that the runtime is decent with a 5 Ah battery. I have 2 x 5 ah batteries and the fast charger, but it doesn't charge fast enough for me to run continuously by switching batteries, you will probably need at least 3 batteries and 2 fast chargers to be able to do that. I think I will get the 9 Ah HP battery to see if that is able to keep the pressure up for a larger part of the battery capacity.
