AirVac VM458 CT18DXQD Belt

Description

Direct replacement drive belt for the AirVac VM455 and CT18DXQD (Poly-V belt) central vacuum power brush. Sold in a two-pack (2 belts). ensures your brush roll maintains full spinning speed — which is what separates deep carpet cleaning from surface-only performance.

About This Belt:
This is the Poly-V (multi-rib) belt variant — fits the AirVac VM455 / CT18DXQD. Verify your power head uses a Poly-V belt before ordering.

Why Replace Your Belt Each Year?

The belt transfers rotation from the brush motor to the brush roll. Unlike a snapped belt that fails obviously, belts degrade gradually: they stretch, glaze, and lose grip over 10–12 months of regular use. A stretched belt allows the brush roll to spin more slowly, reducing the agitation that pulls dirt and debris out of carpet fibers. Annual replacement — even when the belt looks intact — keeps your power head performing as designed.

Signs a Belt Is Due:

• Carpet doesn’t look as clean after vacuuming
• Burning rubber smell during use
• Brush roll spins more slowly or not at all
• Belt is visibly cracked, glazed, or stretched
