Fleas!?!!? 😨😨😨

How do I get rid of them? I've tried sprays I've tried vacuuming every day! I don't want to bug bomb yet because we don't have a washer/dryer so I couldn't wash the sheets and clothes afterwards as instructed and I don't want to put them in my car to drive them to the laundromat. I'm getting bitten like crazy!  My hairless cat doesn't seem to mind them (obvs because she had no hair) and they don't seem to bite her but they drive me crazy picking them off of her all the time! Idk if it helps but we live in Northern California. What do I do :(
