What is a suction polisher?

How a suction polisher works

A conventional polisher spins a pad at maintenance speed — typically 350–400 RPM — and throws fine dust, dried polish and grit into the air and back onto the floor. A suction polisher surrounds the pad with a vacuum shroud: an impeller pulls that debris through the machine into a bag or canister while the pad works. The floor comes up cleaner, the finish stays cleaner, and the air stays breathable.

On the PV25, the vacuum draws up to 100 W through a 40 cm pad path, with the offset motor keeping the machine balanced so the operator isn't fighting torque all shift.

Why it matters

Dust is the enemy of both finishes and lungs. Polishing without extraction re-deposits fine particles into the wet edge of the next pass and into corridor air — a real problem in hospitals, aged care and schools. Suction polishing removes the follow-up dust mop pass, cuts airborne particles, and leaves a harder, cleaner gloss because grit never gets burnished into the film. Hospital-grade variants add HEPA filtration, capturing 99.97% of particles down to 0.3 microns.

Suction vs non-suction: which to choose

Choose suction where air quality or finish quality is critical — healthcare, education, food retail — or wherever a separate vacuuming pass costs you labour. Non-suction polishers remain the simpler, lighter choice for small areas and budget-driven fleets. If the floor is polished daily at scale, the suction machine usually pays for itself in saved passes.

Specs to look for

Pad speed around 375 RPM for maintenance polishing; pad size of 40 cm for the usual balance of coverage and control; vacuum wattage (100 W is standard, hospital canister versions run to 400 W); and serviceability — a sealed gearbox and locally stocked parts decide how long the machine actually lasts. Polivac machines are supported by 225+ distributors in Australia.
