What to you buy to save you time?

I’m a single guy living in a four bed detached house with a garden to match. Despite the bachelor stereotype, I can’t abide mess. So I have recently invested in two robotic vacuums to cut down on cleaning time. One for upstairs and one for downstairs - such a life upgrade for relatively little money.

What other things have you guys now employed which in essence “trade money for more free time”? I’m thinking of ideas which don’t involve people coming in the house. I don’t think the idea of someone cleaning round all my things.
