Narwal J4 Lite – Plus.Parts® Replacement Dust Bin Filters

The Narwal J4 Lite is a lighter-configuration variant in Narwal’s J4 series of combined vacuum-and-mop robots, sharing the J4’s core platform while targeting a more accessible price tier. Like the standard J4, it integrates dry vacuuming with automated floor mopping and uses a dock to manage mop pad maintenance between sessions. The vacuum side of the unit relies on a dust bin filter to capture fine particles before they reach the motor. The J4 Lite is built for regular household cleaning, and the dust bin filter accumulates debris at a pace that depends on floor area and usage frequency. As the filter media becomes loaded over time, airflow through the system narrows and suction at the floor is reduced. Washing the filter at regular intervals and replacing it when the media is spent preserves the J4 Lite’s vacuum performance through its service life.

This replacement set provides Plus.Parts® washable dust bin filters matched to the Narwal J4 Lite housing specification. Five filters are included, each shaped to the original J4 Lite dust bin frame for direct installation without modification. Each filter is hand-washable: rinse under running water, allow to dry completely before reinstalling, and reuse across multiple cycles. Five filters in the pack means a spare is always available while a washed filter dries, a practical format for a robot in daily household use. Filters that do not match the housing profile will leave gaps at the frame edge where air bypasses the media; these are built to the original J4 Lite housing dimensions for full media contact on every installation.
