Which have done tests and report that lower wattage does not mean a reduction in their cleaning capacity. Some do, but many don't and can even do a better job.
If you are thinking of buying a new vacuum cleaner, the best thing would be to visit your local library and read Which's latest reports and be advised by that.
If at first you don't succeed, sky diving isn't for you!
