This Maytag MDB4949SDZ-SS Dishwasher features 5 wash cycles including PowerBlast™, 5 options and a 4 blade stainless steel chopper. The 4 blade chopper pulverizes the food particles that come off your dishes so they don't end up recirculating and sticking to your dishes and glassware. Maytag's 2X Life tested motor is built to last and tested to prove it. Twice life testing based on accelerated 20-year life testing, normal cycle, average use. The full stainless steel tub is built of stainless steel from top to bottom, so it's tough enough to handle high heat and resist cracking and staining for years.
