You also have suction with very hot disks with a hole in the centre. Bernoulli effect in its different emanations. A more practical use of is to just use compressed air to create vacuum like Bernoulli suckers do It's convenient because this way air tools don't need separate vacuum hoses (which are way more expensive, and bulkier than air hoses.)
