A small dishwasher like this makes no sense. The Gota was specially designed for families who have no children or singles who live alone, but if you have that few dishes to wash, why not save your counter space and do it by hand?
I personally don’t get it. The pre-wash cycle fills the dishwasher with steam, while recycling the cooled down residual water for future cycles. That part at least is good for water conservation. The body is made from ABS polycarbonate which can store enough water for one round of cleaning.
