The Bob Dishwasher is an interesting concept. Looking at their website it looks like it would fit 6 plates, 6 cups and a set of utensils. What’s the point of this? If you’re cooking for 6, you would have pots and pans which would have to be hand washed. Is 6 more plates and cups worth going through the effort of loading and turning on a dishwasher? Alternatively, I suppose it is more water efficient..
I would have loved something like that when I was a student and/or when I was single.
I used to have breakfast on the way, lunch at the Uni/work, and a small dinner. 6 plates is therefore close to what I'd use in a week. It's also close to what I'd use nowadays if I weren't still in home office. And while I do have enough room now for a full-sized dishwasher, that wasn't always the case.
His page links to a YouTube review of the Bob where the reviewer claims that it gets things cleaner than it's possible to do by hand, especially irregularly shaped items like electric grill parts. And yes, the dishwasher uses at most 3L, while he estimated sink washing used 10L, not including the 1 min. of running water wasted waiting for the hot water to arrive.
Yes, that was my first impression with dishwasher many years ago. It is plain impossible to achieve this quality with hand washing. Especially for glassware.
I've been in my current place for about 5 years and have never used the dishwasher. Sink works fine and is almost instant if you wash everything immediately.
Personally I think the biggest argument for a dishwasher is that stuff is not in-sight anymore.
They also are more efficient, water wise. Our dishwasher uses 8 liters per wash. If I fill our sink with 8 liters, it barely covers anything. Dish washers use more detergent though, this is why I switched to powder which can be dosed better.
