No. The idea is to make all current vacuum cleaners obsolete and
unsalable and ensure that Bosch who are almost certainly behind the
lobby can outsell better Chinese and Japanese vacuums.



Just out of interest, I have run a check on my best vacuum cleaner,
which is 110V. Sucking it draws 8.8A but with the flow blocked it only
draws 7.6A. So, it's using about 1KW. 1.8KW, unless it's a specmanship
game, seems like overkill. Maybe someone else can run a similar test and
let us know the results

Blocking the flow will cause the amps to drop. It's moving a volume of
air that takes the power, not the suction.
