The Koblenz B-1500-PN is the straightforward 20-inch burnisher: 1500 RPM, a 1.5 HP AC twin capacitor motor and no dust control system to service. When the burnishing happens after hours in an empty building, that simplicity is the point - fewer filters to stock, less to clean out, and 99 pounds of all-metal machine that does one job well.
Built for
- After-hours gloss maintenance on VCT in offices, schools and municipal buildings
- Contract crews who burnish empty buildings and do not need onboard dust capture
- Multi-floor buildings where the machine has to go up and down stairs
- Teams standardizing on one simple, serviceable high-speed machine
Use cases
Weekly spray-buff and restore
Run a restorer or spray-buff product with a burnishing pad at 1500 RPM and the finish comes back up without stripping. Keeping traffic lanes glossy on a schedule is what keeps a strip-and-recoat off the calendar.
Empty-building work
With no dust control shroud to load and clean, this is the lower-maintenance choice when nobody is in the building. Crews that burnish at 2 a.m. in an empty school generally do not need onboard dust capture, and the filter is one more consumable to buy.
Multi-floor routes
Stair climber wheels and a handle designed to fold down for storage make the machine practical to move between floors and park in a standard janitorial closet.
Older electrical service
A 1.5 HP 1500 RPM machine draws less than an ultra-high-speed 2000 RPM unit. In older buildings, crews regularly report the faster machines popping circuits, which is not a problem you want to discover mid-shift.
Why crews choose it
Full pad contact and smooth balanced operation are what separate a burnisher that leaves an even gloss from one that leaves swirl. The B-1500-PN is built around that: all-metal construction, a cast aluminum chassis and an epoxy powder coated steel shroud.
An onboard circuit breaker protects the motor when a pad loads up, which is the most common way a burnisher gets hurt in the field.
Four 5-inch non-marking wheels transport the machine across the floor you just polished without leaving scuff marks behind.

Frequently asked questions
What is the difference between a burnisher and a floor buffer?
A buffer runs near 175 RPM and does the wet work: scrubbing, stripping and bonnet cleaning. A burnisher runs at 1500 RPM and dry-polishes 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 more, but higher speed also draws more current and can trip breakers in older buildings.
How often should floors be burnished?
Most facilities burnish main traffic lanes weekly and low-traffic areas less often. The right frequency is whatever keeps the finish from dulling enough to need a strip and recoat.
Does this model have dust control?
No. The B-1500-PN is the version without a dust control system. If you burnish in occupied or dust-sensitive spaces, look at the B-1500-CN or B-1500-FCN, which add a dust control shroud and filter.
What pad should I use?
Burnishing pads are matched to the finish and the speed. White and champagne pads are common for high-speed polishing on new or well-maintained VCT; more aggressive pads are used on heavier soil. Message us with your finish and we can point you at a pad.
