Broadly speaking, higher wattage motors do mean more suction, and it's become the 'lazy' way of manufacturing vacuum cleaner motors. Whether you realise what you were inadvertently saying this, Turbo, I have no idea, but the late 1970's and early 1980's was a time when it was proven that a relatively low wattage motor can produce some amazing amount of suction power, if the design of both the motor and the cleaner is correct. So yes, I am pleased that manufacturers are reflecting on the past for inspiration.
In a world where suction power is everything, there can be no way that these cleaners with their lower wattage motors would be anything less that their high-wattage predecessors. But as I thought, manufacturers are unlikely to be advertising the wattage on the outside of the cleaners in the same way they became accustomed to doing in the last 25 years.
