The reason why homeowners choose portable dishwashers is simply because they are mobile. They have wheels on them so you can roll them into a store room when not in use. Some people let their portable dishwashers sit atop an existing countertop. Although using them can be more tedious than a permanently installed unit, but such is the tradeoff if you wish to avoid a crowded kitchen.

When operating one of these, they must be moved next to the kitchen sink so you can connect the hose. Basically you're done with the installation. Then you go about operating it just as you would a permanent unit. Rinse the dishes and utensils first to remove the grease so as to avoid clogging. As for maintenance, clean the walls of the machine occasionally using vinegar. You can also run the machine with a cup of vinegar so that the hard-to-reach places get cleaned too.

Now here's the real nice part about investing in a portable dishwasher--because you bought one due to space limitation, you can now actually add more space with it. And this is due to the fact that a portable dishwasher’s top can act as a countertop. You can use it to stack some of the stuff you use while cooking for any other tasks that you perform in the kitchen.

As for their functionality, just like conventional units, they usually have two levels with each contain two rolling baskets for placing the dishes into. While they don’t usually boast the usual whistles and bells of their large cousins, portable units do have enough settings for the owner's convenience. As an example, there are units that have a super cycle for pots and pans while others offer an extra setting for icnreasing the water temperature when the house’s hot water supply is low.

Basically there is not much difference in functionality between a portable and a fixed unit if washing dishes is what you are really intend to achieve. Needless to say, you should study each model carefully if you are unfamiliar with portable units then compare each one to a fixed unit that you are already familiar with. This will certainly save you a lot of trouble or regret later on. You can visit your favorite appliance store or even shop for them online.
