Maytag's foray into the world of portable dishwashers currently includes the MDV4809AWW (and AWB), which is a full-size console model that looks like an ordinary dishwasher, and can handle up to 14 place settings, which is quite a bit more than many other portable units, particularly the countertop variety. The Jetclean has multiple wash cycles, a food disposal device, and promises quiet operation.
So, how does it compare? Well, unfortunately this is where user experiences start to diverge from what Maytag might like. Citing the new "energy efficiency" laws, these newer units sometimes require multiple cycles to accomplish the same amount of cleaning as older units that were more powerful. Unfortunately, energy efficiency in this case does not lead to greater energy efficiency, with poorly cleaned dishes becoming a recurring problem. Durability is also an oft-cited issue, with only a limited warranty to help deal with breakdowns.
On top of all that, it's not particularly cheap, either. The unit can cost over $600, which is more expensive than some other, more highly reviewed alternatives. It seems like quality at Maytag has suffered in light of the energy efficiency mantra, without offering an equally highly performing unit as older models that customers rave about. eBay occasionally has some of these older models.
It's not all bad, but just make sure to compare alternatives before buying.
