Product review (5 stars): Energy consumption graphs attached
Bought mine at Walmart, but decided to share my measurements in case you want to run this via an inverter. This will help you size the peak power of inverter and the battery capacity. I measured all cycles, but only translated one graph into English (the Quick Wash cycle #4), however the graphs are self-explanatory and the curves are so distinct that you will have no trouble recognizing them. I plotted Watts consumed as measured every second with a WhattsUp meter and Watts/hour total. Keep in mind that if you use an inverter with modified sine wave the washer may perform differently (worse).

The water usage is as follows per EACH rinse cycle:
High = 17 gallon = 65 liter
Medium = 9.2 gallon = 35 liter
Low = did not measure
Extra Low = 5 gallon = 19 liter

Great little unit both as a primary and as a backup washer.
