I do a couple of loads a day, because I cook with some intensity, and love to use lots of pots and colanders. I love to cook and often cook elaborately and fill a dishwasher quickly. I also do a lot of half loads, which I do defiantly. It suits my convenience to do a lot of loads, and Bosch's seem to be cool with that.
One thing I have to do is fill that "agent" tray often, which seems to really help.
Also the Bosch is very quiet! Makes time in the kitchen more pleasant.
My present model has a quick wash, only 36 minutes, which is very handy and is almost as good as the other washes. If you have lightly messy dishes by all means use the quick wash. I also like the hygenic wash.
So I'd recommend being sure to get the one with the quick wash. I suspect that this wash uses a lot of water and energy so you can grin and curse Al the Tyrant. So far I don't have to use a shower hose to clean my dishes.
What is an agent tray?
Bosch is the best!
