Soft mount commercial washers
You do not find many soft mount washers in laundromats because they are so expensive to buy, often 2x - 4x the price of the hard mount machines. Plus, the business is built on the washer taking 30 mins for its cycle and the dryer taking 30 mins to dry, so the machines are always in use (if you are lucky) making revenue. With high speed extract washers, the clothes dry quicker, and the owner loses revenue on the shorter dry times and the dryers sitting vacant unused for part of that old 30 mins timing. So washer prices get jacked up and/or minutes per quarter in the dryer goes down to make up the revenue. There is a trend in dryer pricing for "complete cycle" drying, where you have to purchase 30-35 minutes from the get-go which will dry most loads.
