All models have a good water flow and pressure ratio, it is more important to think about the tasks you shall be using your washer for.

Store your power washer in a dry place that is well ventilated, in the winter months you may want to cover the pressure wash up or bring it inside and store somewhere that is heated to ensure the pump does not freeze and become damaged with any water left inside.
