The critical measurement for a small-space countertop dishwasher is not the advertised capacity โ€” it is the actual height. Standard upper kitchen cabinets in U.S. kitchens have 18 inches of clearance above the counter. Any dishwasher taller than 18 inches will not slide under the cabinets without leaving the cabinet door open, which creates a permanent obstacle on the counter. I measured the height of every unit in this test independently and found that some advertised heights were off by 0.5 to 1 inch.

Why trust this review

Three years reviewing kitchen appliances with a focus on actual measurements versus manufacturer specifications. All units were purchased at retail.

How we tested countertop dishwashers

Each unit was measured with a tape measure for actual height. Cleaning performance was evaluated on a standardized load: 4 dinner plates, 4 glasses, 4 mugs, 2 bowls, and a full utensil basket with dried food residue left for 12 hours. After the normal cycle, items were inspected for food residue at 6 preset locations. Noise was measured at 12 inches from the front panel during the wash phase.

Who should buy the Comfee?

Buy this if you have a studio apartment or small kitchen without a built-in dishwasher, if your counter-to-cabinet clearance is 18 inches or less, and if your typical dish load is for one or two people.

Skip it if you regularly cook large pots, use baking sheets, or need more than 6 place settings per run. For larger households, a portable countertop dishwasher with faucet connection and higher capacity is a better fit.

Cabinet clearance: why the Comfee wins

At 17.2 inches tall, the Comfee fits comfortably under the 18-inch standard clearance with 0.8 inches to spare. The Farberware, despite being labeled a โ€œcountertopโ€ dishwasher, measures 19.3 inches tall and does not fit under standard cabinets without modification. Measuring your cabinet clearance before purchase is the single most important step in selecting a countertop dishwasher.

Cleaning performance

In the standardized 12-hour-dried-food test, the Comfee on the Normal cycle removed all food residue from flat surfaces and 90 percent from curved interior surfaces like mugs. Stubborn baked-on food required the Heavy cycle, which resolved the remaining residue. The Normal cycle handled everyday dishes without issue.

The bottom line

For small-space kitchens with 18-inch or less cabinet clearance, the Comfee is the right choice. Measure your clearance first, verify the height specification independently, and accept the manual fill routine as a minor inconvenience for the space-saving benefit.

Frequently asked questions

Do countertop dishwashers actually clean dishes well?+

Yes, quality countertop dishwashers clean standard dishes, glasses, and utensils effectively. The limitation is capacity (6 place settings) and the inability to fit large pots and pans. For one or two people, they handle everyday dish loads adequately.

How much water does a countertop dishwasher use?+

Most countertop dishwashers use 3 to 4 gallons per cycle. Hand washing dishes under running water typically uses 9 to 27 gallons. Even accounting for the difference in cleaning capacity, countertop dishwashers are significantly more water-efficient.

Do countertop dishwashers need to be connected to a sink?+

Tank-fill models like the Comfee do not require a permanent connection. You fill the built-in water tank manually before each cycle. Faucet-connect models use a quick-connect adapter on the faucet and drain into the sink. Tank models are easier to place anywhere on the counter.

How loud are countertop dishwashers?+

Most countertop dishwashers run at 52 to 58 dB, which is audible but similar to a normal conversation. They are louder than built-in dishwashers, which are often 40 to 50 dB. Running during periods when kitchen noise is already present makes the sound less noticeable.
