Budget robots earn their keep through simplicity, and the Grixx KK8 is a reliable example of that principle. Part of the extended KK8 family sold across Europe under various brand names, it uses bristleless direct suction and four spinning side brush arms to sweep and collect from hard floors and low-pile carpets. The random-bounce navigation keeps it unpredictable but persistent, and its compact 0.3-litre bin means it works best with daily or every-other-day runs. Over time, the HEPA filter behind the bin collects fine debris and begins to restrict airflow, and the brush arms wear down at the tips where they do the most sweeping work.
This set provides the direct-fit replacements for both: one HEPA flat filter and four side brushes, five pieces total, all sourced as Plus.Parts® components matched to the Grixx KK8’s original dimensions and fitting points. Neither part requires tools to swap, and fitting them takes under a minute. A clogged filter and flattened brush arms are the two most common reasons a budget robot starts underperforming, and both are addressed in a single order here.
Parts are selected and stocked based on consistent fit across the KK8 platform variants. Reach out if you need to confirm compatibility for your specific variant.
