The night floor is where her socks land. A floor mopped with the wrong product, left damp, or waxed in a thin line near the bed can look fine in daylight and still be slick at 3am. Before you decide who keeps that floor clean, decide who checks it, because the check is the part that matters on the route.

What doing it yourself actually takes
Clear the six stops first. Move the rugs, the cords, and anything stacked on the floor. Sweep, then mop with a damp cloth, not a wet one. Let the floor dry fully, which can take longer than you expect on a humid evening. Then walk the route in socks with the lights off and feel for tacky spots, grit, or a film under the feet. Write down the date, the product name from the label, and whether the walk was clean.
Doing it yourself gives you control over the product and the timing, and it puts you on the floor where you can see any residue. It also uses your own hours, and a floor done on Saturday can still be wrong by Tuesday.
What hiring it out needs in writing
A cleaning service or floor care crew can do the same job, but only if you tell them exactly what the job is. Ask what product they use and whether it is a wax, a polish, or a cleaner. Ask whether they leave a film and whether they will dry the floor and wipe the edges by the bed and the bathroom door. Ask whether they will set the furniture back in the same spot and whether they will skip any rug that comes up for the night. Ask who will be on site and whether you can talk to them before the visit.
Put those points in writing on the job order. A verbal promise that the floor will be safe is not something you can check at 3am.
Compare the two honestly
Put both options on the same card. For each one, write who does the work, what product gets used, how long the floor takes to dry, who runs the night walk, and what happens if the floor is slick the next night. The option you can call and get fixed quickly is usually the right one for the route, even if it costs you more of your own time.
What to write down after each visit
Write the date, who did the floor, the product name, the drying time, and the result of the night walk. Add one line for anything that felt different underfoot. Keep the card with the route notes so the next person who mops has the same instructions you did. If a label is unclear about use on a floor she walks at night, ask the maker or the seller before you use it, and keep the label.
