The cups are definitely dishwasher safe. i've put mine in (with heat/dry) and things are fine. I wouldn't put in the actual blade part though... but usually just a quick rinse with tap water and it's fine.<br><br>
The one thing they really don'' mention in the commercials is that (i guess due to the motor size?) you're not supossed to 'blend' for more than 30 seconds at a time. It's the only realy negative thing that I've read on user review reports - that the motor didn't hold out, but it was also due to overuse, from what I recall.<br><br>
Most smoothies, salsa, etc are easily done by then. If not, just let the motor cool down for 30 seconds to a minute, and do it again. A little common sense will go a long way with this product.
