Narwal J4 – Plus.Parts® Main Brush Replacement Pack

The Narwal J4 enters the Freo lineup as the ambient-wash model, pairing 8,200 Pa of suction with the Reuleaux triangular mop pads and a self-scrubbing dock that keeps mops rinsed without needing hot water or warm-air drying. It handles combined vacuuming and mopping in a single pass, storing used water in a 1-litre dock bag that typically lasts six to seven weeks between changes. The zero-tangle floating roller brush handles all hard debris and hair, self-adjusting for carpet pile depth as it goes. Like every Narwal, the J4 rewards a consistent maintenance routine: the roller brush benefits from a bearing-cap check every two weeks and should be replaced at the three-to-six-month mark when its flexible compound begins to lose the engagement with the floor that makes the zero-tangle claim hold up in practice.

This pack holds three washable Plus.Parts® anti-tangle main brushes, each matched to the J4’s floating arm mounting geometry for a direct-fit swap. The brush compound is flexible enough to maintain floor contact across the full replacement interval, which distinguishes it from cheaper alternatives that harden within a few months and start dragging rather than picking up.
