Rubbermaid Ergo Reach Mop

Commercial-grade mop with extending handle and swivel head: none of that wussy consumer-grade stuff
Sprays cleaning fluid, but refillable reservoir is strictly BYOCF
Includes one disposable dry/wet pad and one reusable wet pad good for up to 200 uses, which, given how often we mop, would last us for years to come
You can get extra dry/wet pads here
Model: 1887488 (an all-numerical model number is a risky move for searchability, but this one pulls it off - Google it yourself and see)
