For me, it’s an electric toothbrush. It doesn’t matter if you go with Sonicare or Oral-B, once you start using an electric toothbrush, regular toothbrushes don’t ever feel like they clean your teeth properly. The smooth plaque-free top layer of your teeth that you can feel after using an electric toothbrush can’t be replicated with a regular toothbrush.
Robot vacuum. My floors are spotless except for some areas you’d never walk on and I only need to do some spot cleaning every month or two.
Dishwashers are awesome too, watch Technology Connections’ video on YouTube if you think your dishwasher doesn’t do a good job. It’s likely just how you’re using it. Priming the hot water before running, using powder detergent instead of liquid or packs (booo), and using the pre-wash and rinse aid will have even the gnarliest dishes coming out spotless.
Love my robot vacuum! As someone who works 12+ hours a day, it’s such a life saver. We have had our Roborock for 4 years now and it has 0 issues. Any issues I had were easy fixed by just opening the thing up and cleaning inside.
Absolutely love watching Technology Connections. Dude improved my dishwasher game by 400%
