I didn't answer the poll because I had a cleaner until this month and it felt disingenuous to mark that I have no outside help. :)
I got a cleaner when my DS was born and I was very ill after DD was born so I kept her on longer than I had intended. Recently, though, we moved and I realized I could just set up new cleaning routines for the new house and apply those.
Plus the kids are older and help a lot. They do laundry if you don't care about well-folded clothes, take out the trash and recycling, make the beds, vacuum, sweep, dry dishes, mop if you don't care about edges, clean bathrooms, etc. Not that all of that falls on them, but I can call on their assistance for any of those things and they can get it done. I've taken a modified Montessori approach with training them and getting them their own child-sized cleaning tools. DD still uses them but DS uses the adult tools now.
It helped to simplify the materials. I've got it down to a bottle of diluted vinegar with pine essential oil for most cleaning, bleach cleaner for the occasional thing that needs sanitizing or bleaching, glass cleaner, and a shaker bottle of baking soda with pine oil mixed in. I made a cleaning tote with those bottles, sponges, paper towels, and microfiber cloths. I have a broom, a mop, and a vacuum. DD has her own smaller versions of gloves, broom, mop. That's it.
If I had houseguests coming to stay over, I would probably call the service again to help me deep clean. My house is clean enough for people to stop by, but not great.
