SATURATING FLOOR WITH A SLOP MOP
First of all slop mops … or bucket mops … are not appropriate for most residential situations and even in many commercial environments where a clean and shiny (VCT for example) floor is desirable.
Slop mops are, however, effective for mass cleaning of very nasty situations such as vomit and large areas that are not shiny showroom like surfaces.
A big fat cluster of nylon strings are put in a bucket of cleaner/water applied to floor then the mop is squeezed out to remove as much dirty residue as possible. Sound great but the same bucket of cleaner is exposed to the dirt every time the mop is reapplied resulting in smearing dirty residue back on floor. If you change the bucket water often enough to prevent this you would never finish.
Another note… the sheer volume of water hitting your hardwood floor will test your polyurethane protection coat… If it’s degraded or has none on it (some call it “wax” but it’s actually polyurethane) you could damage the floor.
