The Koblenz B-1500-CN is a 20-inch high-speed burnisher built for the crew that has to bring gloss back to VCT in a building that never fully empties. The 1500 RPM pad speed restores shine on a weekly spray-buff cycle, and the onboard dust control system with its flexible skirt captures the fine finish powder burnishing throws off instead of leaving it to settle on desks and return air grilles.
Built for
- Weekly spray-buff and restore cycles on VCT in schools and offices
- Retail and grocery aisles that have to look glossy at open
- Healthcare and clinical corridors where airborne finish dust draws complaints
- Buildings on older electrical service where a 2000 RPM machine trips breakers
Use cases
Maintaining gloss without stripping
Burnishing is the maintenance step that lets a finish coat last. A weekly pass with a restorer or spray-buff product at 1500 RPM keeps traffic lanes from dulling to the point where the floor has to be stripped and recoated, which is where the real labor cost lives.
Occupied and dust-sensitive spaces
The flexible skirt and dust control system pull burnishing residue into the machine rather than into the air. In a clinic, a school or a tenant office cleaned around occupants, that is often the difference between burnishing during the day and being pushed to a weekend.
Facilities with limited circuits
Floor-care crews are consistent on this point: ultra-high-speed 2000 RPM burnishers will pop circuits in older buildings. A 1.5 HP 1500 RPM machine is the safer standard when you do not control the panel, and for most spray-buff work 1500 RPM is all the speed the job needs.
New crews on long corridors
The fixed handle keeps the head tracking in one plane, which makes straight lanes down a hallway predictable for an operator who is still learning the machine.
Why crews choose it
A cast aluminum chassis under an epoxy powder coated steel shroud keeps the machine at 102 pounds without the cable: heavy enough for full pad contact, light enough to load into a van without a lift gate.
Four 5-inch double ball bearing non-marking wheels roll the machine between rooms across finished floors without leaving the black scuff trail cheap transport wheels leave behind.
A 50-foot 14 gauge grounded cord and onboard circuit breaker mean the machine is protected and can work a full corridor from a single outlet.

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.
Does the dust control system need a filter?
Yes. The dust control system routes burnishing residue through a filter. Keeping a clean filter in place preserves both airflow and the air quality benefit, so it is a wear item to stock alongside pads.
What warranty comes with the B-1500-CN?
Koblenz covers this machine for 5 years against manufacturing defects. Pads, filters and the cord are normal wear items and are not warranty parts.
Discount Cleaning Products is an authorized Koblenz dealer. Every machine ships new in the factory carton with the full manufacturer warranty, and our US-based team can match pad drivers, pads and replacement parts to the model you own so a routine wear item never turns into downtime.
