A few years ago, the average 2ltr diesel car was pushing out 50-60 bhp and took a fortnight to get up to any decent speed.
Nowadays we are looking at common rail engines of the same displacement pushing out 150-200 bhp, top speeds of around 140mph, and with 0-60mph times quicker than most petrol variants.
These new domestic appliances will have to perform or they won't sell.
I use a V-tuf industrial wet/dry in the workshop, the motor is 1000w with 230 m/bar suction and 53 L/sec airflow, more than adequate for de-swarfing all of the machine tools.
I recently bought a new chest freezer ( the old one died after nearly 30 years service), the new one uses a third of the power of the old one and hardly ever seems to be running, despite that it gave no problem keeping temps down to the proper levels even when subjected to the recent heatwave – the freezer is in the conservatory and temps went up to 130F.
Technology is moving on.
