Yup! Bendix poisoned the well for combos and even hurt their own sales by the reputation combos got for being inefficient, troublesome machines. Bendix patents prohibited any combination from having the suspension necessary to allow sufficient spinning. In today's world, everyone would just put their name on a Bendix combo and that would be that but back in the 50s, everyone had to make their own so they made machines that could not spin well. After companies invested so much money in tooling up to build combos, they did not recoup the investment to make significant improvements, although what they could have done while hobbled by the patent issue is unknown. Because of the volume of machines Sears sold, they had money for Whirlpool to completely redesign the combos for Sears in the early 60s. They came up with a machine which had 1600 parts by a count John's brother Jerry made; just as many as a VW Beetle. An ingenious or maniacal balancing system allowed it to spin at 500 rpm in the early models then 400 rpm after some major and necessary redesigning took place. It spun about as well as a Kenmore top loader on slow spin, but it was the best extracting combo other than the Bendix design.
Consumer Reports and Consumer's Research Bulletin decried the expense of operating the combos, mainly because they took so long to dry the poorly extracted loads. You have to remember that about the time that combos appeared, many homes were being built without basements and without traditional laundry rooms, those post WWII starter homes. They had a space in the kitchen, or bath or hall closet that would allow a washer or sometimes the stacked Westinghouse units, which had their own plague of problems, but not a washer and a dryer. Combos seemed like the answer to prayers, but the compromises were pretty large in performance and construction. Even today, you look at these beautiful machines and have such high hopes for washing and drying in them and when you do and see all of the shortcomings in performance. Then you read in the postings by Greg and others who have restored some of these machines about how design flaws and inadequate materials at the time led to more problems, except for the Bendix machines which were well built and tested very well when Consumer Reports rated the Duomatic.
