I see you have recommended three vacuums. I’ve been told that vacuuming fleas up doesn’t kill them and that a vacuum without a Very fine HEPA filter actually blows eggs out the exhaust and around the room. I was also told that emptying a plastic upright Dyson type canister A) allows fleas and fleas staged to escape and also leaves fleas developing in and on the vacuum. B) regardless of vacuum, the filter should be removed from the vacuum, placed a sealed plastic bag and frozen, if you plan to use it again.- same with the bag, if you plan to use it again.
There was a study done in 2007 showing that fleas can’t survive being vacuumed up:
Vacuuming is lethal to all postembryonic life stages of the cat flea, Ctenocephalides felis
I’ve summarized the journal article, along with other research I’ve found, on the page Can fleas survive in vacuums.
Still, sanitizing the bags or canisters can’t hurt.
