Overview
The Whirlpool WMCS3018RW is a 0.7 cu ft, 700-watt countertop microwave with a turntable, steam clean function, and electronic touch controls. It suits singles, small kitchens, dorms, and anyone who needs a compact microwave rather than a full-size family unit.
Its steam clean setting (a bowl of water plus a button) is the standout feature, letting you loosen splatters without scrubbing or chemicals. At 0.7 cu ft it's genuinely small - fine for a mug or single plate, but a bag of popcorn or a wide plate can catch on the turntable as it spins. The child lock also re-engages the door after each cook, so it needs unlocking before reheating again.
- 0.7 cu ft capacity, 700 watts
- 10 power levels plus 4 express buttons
- White LED display, electronic touch controls
- Child safety lock included
Who it's for
Fits people who reheat single portions, live alone, or need a microwave for a small kitchen, RV, or office nook. Families who regularly heat large plates or multiple portions at once will find the interior cramped.
