Overview
The Koblenz P-1800 is a corded floor scrubber and buffer with a 4.2 amp two-speed motor and bronze gears, built to scrub, polish, buff and wax tile, hardwood, marble, vinyl and other hard flooring.
It ships with lambswool pads and scrub brushes and holds a 144oz cleaning solution tank. It does not extract dirty water, so it works alongside a mop rather than replacing one for wet cleanup.
- 4.2 amp two-speed motor with bronze gears
- 144oz solution tank for scrubbing and waxing
- Includes lambswool pads and scrub brushes
- One-year warranty on defective parts
Who it's for
Suited to owners of tile, stone, hardwood or vinyl floors who want a periodic deep scrub and shine rather than daily light cleaning. Not for anyone expecting it to vacuum up dirty water on its own.
What buyers say
From Amazon customer reviews.
Several reviewers replaced a Koblenz that had lasted 20 to 25 years with this same model and reported the same results, a strong shine on hardwood and stone floors. Complaints center on build quirks rather than cleaning power: the unit will not stand upright on its own and needs to lean against a wall, the switch box location makes winding the cord awkward, and two buyers received damaged units, one with internally rusted pipes and one with a cracked wand control.
