They certainly are going the right direction but manufacturers will always find a way to cheat. E.g. my Samsung washer (never again!) has an eco mode that runs 4 1/2h. No idea what it's doing during that time, but I guess it maximises on some criteria that are regulated. It would be absurd to prohibit other modes, so they exist and we use them fairly often as we just want to get laundry done...

On vacuum cleaners - i would hazard a guess that you are in the UK where this has been a major talking point e.g. during the brexit referendum. Truth is that there are plenty of studies showing that new vacuums are as good as old ones and just use less energy. Regulating vacuums was a huge success in that sense. Of course if you get a 40£ tesco vacuum they fared better before they were obliged to try and be efficient, but by a proper brand and you shouldn't notice any difference (except where the brand maybe decided to reduce cost e.g. Dyson has gone downhill for years and recently decided to move HQ to Singapore...).
