Countertop dishwashers are compact appliances designed for small kitchens or limited spaces. They sit on the countertop and connect to the kitchen faucet, making them easy to install and use. These dishwashers typically hold a smaller load than standard models, making them ideal for individuals or small families. Most countertop dishwashers offer multiple wash cycles and energy-efficient options, helping to save water and electricity. They are suitable for washing various items, including plates, glasses, and utensils. Brands like Danby and BLACK+DECKER offer popular models that cater to different needs and budgets.
