The Koblenz B-1500-FCN pairs a 1.5 HP DC rectified motor with a floating handle, so the 20-inch pad follows the floor instead of the operator. Combined with the dust control system, it is the configuration crews pick when the burnishing route runs across uneven older VCT and through spaces where airborne finish powder is not acceptable.
Built for
- Weekly gloss maintenance on VCT in schools, offices and municipal buildings
- Older floors with slab movement or lippage where full pad contact is hard to hold
- Dust-sensitive corridors in clinics, labs and food service areas
- Contract crews who store machines in a tight closet or van
Use cases
Uneven and older floors
A floating handle lets the head find its own plane. On a slab with settlement or on VCT laid over an older subfloor, that keeps the full pad on the floor through the pass instead of riding one edge, which is what produces swirl and uneven gloss.
Dust-sensitive occupied spaces
The dust control system captures the fine finish residue burnishing generates. That is what makes daytime burnishing possible in a clinic corridor or a food service area rather than deferring it to a weekend shift.
Long uninterrupted runs
The DC rectified motor is built to run cool and continuous, which suits a burnishing route measured in hours rather than rooms. The onboard circuit breaker protects the machine if the pad loads up.
Tight storage and stair access
Stair climber wheels and a handle designed to fold down for storage make the machine practical to move between floors and to park in a standard janitorial closet.
Why crews choose it
The floating handle can also be locked to a fixed position, so the same machine works for an experienced operator who wants the head to float and for a newer one who wants it to track.
All-metal construction with an epoxy powder coated steel shroud is what keeps a burnisher serviceable past the ten-year mark; floor-care crews routinely report 1500 RPM machines of this class still running after two decades.
Four 5-inch non-marking wheels transport the machine across finished floors without scuffing the surface you just polished.

Frequently asked questions
What is the difference between a burnisher and a floor buffer?
A buffer runs at about 175 RPM and does the wet work: scrubbing, stripping and bonnet cleaning. A burnisher runs at 1500 RPM and does the dry work of polishing an existing finish to a gloss. They are complementary machines, not substitutes.
Is 1500 RPM fast enough for VCT?
For routine maintenance, yes. 1500 RPM is the common standard for weekly spray-buff and restore work. Very hard wet-look finishes sometimes call for 2000 RPM or higher, but higher speed also draws more current and can trip breakers in older buildings.
How often should floors be burnished?
Most facilities run a weekly cycle in main traffic lanes and less often in low-traffic areas. The right frequency is whatever keeps the finish from ever dulling enough to need a strip and recoat.
What does a floating handle actually do?
It lets the burnisher head pivot to follow the floor rather than being held rigid by the operator. On uneven floors that keeps full pad contact and reduces swirl. On this model the handle can also be locked in a fixed position if you prefer it rigid.
What is the advantage of a DC rectified motor?
A DC rectified motor is built for cool, continuous running on long routes and tends to hold speed under pad load. It is the choice when the machine runs for hours at a time rather than in short bursts.
