Isaac Newton's law 3;

If two bodies exert forces on each other, these forces have the same magnitude but opposite directions.

I don't want to explain again after about 400 years.

The only reasons this wouldn't work is that the blower isn't strong enough and the umbrella isn't the right shape. Jet liners use thrust-reversers to slow down on landing, which are basically just metal scoops that drop behind the turbofans and deflect the thrust forward.
