Recirculating sprays were introduced in European FLs long before Electrolux introduced it here. I remember seeing the feature in ads in European magazines in the 80s, I believe.
If you want good rinsing, the Speed Queen FL can give rinsing. I let mine go through the usual cycle with two rinses and the final spin. Then I reset the selector to Rinse & Spin and let it go through a third rinse after the good extraction of the thorough final spin, 1000RPM in a large tub. The great extraction means that the final rinse is clear. The machine is far from perfect but, in an age when the bean counters determine the effectiveness of washers and dishwashers, it can deliver good results, especially if you follow the instructions given on this site for increasing the water level up to the edge of the door opening.
As for hot water washing, either purge the lines by running a faucet close to the machine or, before loading, let it fill with hot water and tumble for a couple of minutes to heat up the metal tubs then turn the selector to OFF, then to SPIN to drain it, then back to OFF when it is empty. wait for the door to unlock then quickly load it and start your HOT wash cycle. If you don't keep you water heater set to 140F, you are not going to get a hot water wash without a heater in a washer. Many machines that offered heaters no longer offer them because the nation's bean counters want us all to wash in cold water.
