Having a cleaner removes a lot of stress from my life.
You need good communication. On day one, I brought my cleaner through all the things I’d like done as a minimum each week, and how it should be done. Also discussed more ad-hoc thinks that don’t need to be done weekly and she does those on rotation.
A cleaner should spend their time cleaning, not tidying so you do need to get into a routine of keeping things fairly tidy and areas clutter-free. To me, this is a benefit of having a cleaner as it keeps me disciplined and means I don’t get to the stage where I’m overwhelmed with mess.
On the night before she comes, I do a quick ten mins to remove anything from the floors (we have a dog- there are many sticks and toys), make sure that I have surfaces clear, and tackle anything the cleaner shouldn’t. For example, I don’t ask my cleaner to do anything related to laundry so I’ll make sure any towels that are due a wash are put into the laundry basket because she won’t be looking out for them, and I want them out of her way.
I supply all cleaning equipment and have everything in a big caddy so take those out the night before, add clean clothes etc.
If I’m running low on any cleaning supplies, my cleaner will let me know so I can get some more.
Honestly, having a cleaner is probably the best thing I spend money on in terms of the benefit to my mental health. I’m not a naturally tidy person, but knowing she’s coming every week is enough motivation for me to keep on top of tidiness, and the fact that she does the heavy cleaning once a week means I only have to spend a few mins each day doing interim cleans to keep everything looking great.
I now have a house where I’d be happy to have a surprise visitor come in, whereas it would previously have been my worst nightmare.
