Pyridine is pretty horrible… Don’t really know how to describe the smell: like a mix of rotten cum and ashtray? It overpowers any other smells, gives me instant headaches and the stench can linger for hours.
Dimethyl sulfide is also pretty disgusting to me, kinda like… a kitchen that’s been used to cook brussel sprouts for 20 years + garlic breath?
Absolutely can second this. In my case I just spend 5 minutes each morning making sure there’s nothing on the floor before the robot does its thing, and it’s helped tremendously. Stuff used to get moved around to places it didn’t belong and just stay there - but not anymore.
I also make sure to never leave a room empty-handed, if there’s something that needs cleaning up. Just pick up a glass on my way to the kitchen, or a toy on my way past the kid’s room - at this point it’s just automatic, takes nearly zero extra time or effort, and has a huuuuuge impact. I think I’ve only purposefully tidied the apartment once in the last 6 months, because stuff just no longer builds up to the point that it becomes a big mess.
