Dual-speed (or twin-speed) floor machines have grown in popularity, machines like the Viper DS350, Karcher BDS 43 Duo Dual and the Numatic NRT1530 — but are they really the best solution for your floors? Let’s break it down.
At low speed (150–175 RPM), dual-speed machines perform decently. They're great for tasks like wet scrubbing or stripping. No complaints there.
But the problem is the “high speed.”
Most dual-speed machines top out at 300–350 RPM — and that’s just not fast enough for effective polishing or burnishing. The result? You waste time and still don’t get the professional shine you’re after.
Take it from years of experience in NZ and Australia: trying to polish a floor with 400 RPM is like mowing a lawn with scissors — it gets the job done, eventually, but painfully slowly. Worse still, try using that speed for wet scrubbing and the solution just flies out from under the pad and evaporates before it works.
Here’s the smarter alternative: Our Dual Machine Combo.
Instead of one machine doing two things poorly, we’re offering you two machines, each optimized for what they do best.
CE27525 Heavy-Duty Low-Speed Polisher
175 RPM – the ideal speed for deep scrubbing
16-inch cleaning path
Includes water tank, pad driver, hard nylon brush (for concrete), and soft brush (for carpet)
CE27514 Corded Electric Burnisher
1500 RPM – the speed you actually need for a brilliant shine
20-inch head for faster coverage
Straight-line design – no swing, just smooth, easy operation like a lawn mower
The Result? Faster jobs, better outcomes, and machines that last longer because they’re not being pushed beyond their design.
