Devanti 150W Cordless Stick Vacuum — Motorised Roller Head, HEPA-Grade Filter | AU

A 150W cordless bagless stick vacuum with a motorised roller head — the brush bar is driven by a dedicated in-head motor, not airflow, making it more effective at agitating carpet fibres and lifting embedded debris than a passive-head design. 8,000 Pa suction, washable HEPA-grade filter, up to 35 minutes runtime on low speed. Converts to handheld.

Who it's for

Allergy-aware households wanting a cordless vacuum with a driven brush bar for carpets, rugs, and upholstered furniture. An upgrade from a passive-head cordless that leaves debris behind in carpet pile. Households that also need handheld reach for stairs, car seats, or curtains.

How it works

The motorised roller head contains a small independent motor that drives the brush bar at a consistent speed regardless of suction level. It physically beats and agitates carpet fibres to dislodge embedded debris — dust mite particles, pet hair, fine grit — rather than relying on airflow alone to lift surface material.

All exhaust air passes through a washable HEPA-grade filter, capturing fine particles before they're blown back into the room. Rinse the filter under cool water, dry fully for 24 hours, and refit.

Using this vacuum in an allergy-aware home

For best results in a dust mite management routine, combine regular HEPA-filtered vacuuming with dust mite mattress and pillow covers, humidity control below 50%, and weekly hot washing of bedding. An air purifier handles airborne particles between vacuuming sessions.

FAQs

What's the difference between this and the standard Purple model? This model ships with a motorised roller head — a brush bar driven by a dedicated in-head motor. The standard Purple model has a passive head. The motorised head is meaningfully better on carpet. Both have the same 150W motor and 8,000 Pa suction.

Is the filter certified True HEPA? The manufacturer lists it as HEPA-grade.

How long does the battery last? Up to 35 minutes on low, 25 minutes on high. The motorised head draws additional battery power — runtime will be shorter when using it on high speed.

Can I use the standard head instead? Yes — both heads are in the box. Standard head for hard floors and light-touch cleaning; motorised roller for carpet and rugs.
