Scrub the floor
Scrubbing is arm work. A child needs to know how hard to press, how many strokes it takes and where the patch ends, and the pictures below turn all three into something you can point at instead of explaining twice.

About this visual support
Force is what separates scrubbing from wiping. The brush has to meet the floor with weight behind it, and the stroke has to be repeated until the mark lets go. A child who sweeps the brush across the boards once and finds the stain still sitting there often decides the job is impossible rather than half done. When endurance is the actual task, the child also needs to know where it stops.
Pictures make those limits visible. One image for filling the bucket, one for the grip on the handle, one for the back and forth stroke, and one for the square of floor that counts as finished. The work becomes something with an edge to it, and you stop being asked how much longer.
For floor scrubbing in particular, tape the floor into sections or let the edge of a rug act as the finish line, and let each picture stand for one section. The child can see how much is left without being told. If you would rather carry the sequence on your phone than tape it inside a cupboard door, Routined keeps the steps together and can be tried for fourteen days at no cost before the subscription starts.
