The Koblenz TP2S-2015DC N is the two-speed answer to a problem most crews solve by owning two machines. At 175 RPM it strips, scrubs and bonnets like any low-speed 20-inch; flip to 320 RPM and the same cast iron machine spray-buffs and polishes at a speed a single-speed low-speed unit cannot reach.
Built for
- Facilities that want one machine to cover stripping and spray-buffing
- School, retail and municipal hard floor programs in the 5,000 to 15,000 square foot range
- Contract crews who cannot justify a separate machine for every speed
- Buildings with a mix of VCT, sealed concrete and quarry tile
Use cases
Low speed at 175 RPM
This is the wet-work setting: black pad for stripping, red or blue for routine scrubbing, bonnet driver for interim carpet care. 175 RPM is the industry standard for all of it.
High speed at 320 RPM
320 RPM is spray-buff territory. It brings up a finish faster than 175 RPM without the current draw or the finish-dust of a true 1500 RPM burnisher, which makes it a practical middle setting for buildings that cannot support a high-speed machine.
Mixed-surface buildings
Quarry tile in a kitchen, VCT in the corridor and sealed concrete in the back of house all want different pads and different speeds. Two speeds on one frame keeps that from becoming a two-machine purchase.
Long continuous runs
The DC rectified motor is designed to run cool and continuous rather than in short bursts, which matters when a strip weekend runs eight hours.
Why crews choose it
Triple planetary all-steel gears transmit torque evenly from motor to pad driver. Single and double planetary gearboxes do not balance load across the pad as well, and on a 20-inch head that shows up as a machine that fights the operator.
A cast iron chassis and reinforced epoxy powder coated steel shroud bring the machine to 101 pounds net, which is the weight range crews want over a stripping pad, and are what let a machine survive years of stripper chemicals.
5-inch non-marking wheels with sealed double ball bearings roll the machine across finished floors without leaving scuff marks. The unit carries UL, CSA and NOM certification.

Frequently asked questions
What is the second speed actually for?
320 RPM is the spray-buff and polishing speed. It brings a finish up faster than 175 RPM while still being a low-speed machine electrically. Full high-gloss burnishing is a separate job done at 1500 RPM or more.
Do I still need a burnisher?
If your program calls for a true wet-look gloss, yes. 320 RPM improves shine but does not replace a 1500 RPM burnisher. If your floors only need to look clean and lightly polished, the two-speed machine may cover it.
Is a pad driver included?
No. Match the driver to the work - a pad holder for stripping and scrubbing, a brush for grout and safety tile, or a bonnet driver for carpet. Message us with your pad size and we will confirm the part number.
What is a triple planetary gearbox?
It is the gear set between motor and pad driver. Triple planetary sets balance torque across the pad better than single or double planetary designs, which makes the machine smoother and less tiring to run.
How heavy should a stripping machine be?
Crews generally want a 20-inch machine over 100 pounds because pad pressure is what breaks finish down. At 101 lb net this machine sits in that range without add-on weights.
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.
