With HEPA filter
A vacuum cleaner with a hepa filter puts out pollen
-free, dust-free air from its exhaust end.
A vacuum cleaner that blows exhaust upward instead of sideways or backwards has less of a tendence to blow dust from the floor into the air, while one is vacuuming. It's best to wear a mask during vacuuming (available at all drugstores), and to use a room hepa filter afterwards to clear the air.
