Roborock G20S Ultra – Plus.Parts® Maintenance Set

The Roborock G20S Ultra is the slim-chassis variant in the S-series line, built on a low-profile body that reaches under sofas and beds most full-height robots cannot access. Its single rubber brush runs in a tighter housing than on taller S-series models, concentrating hair and fibre accumulation at the bearing seats rather than mid-roll, and its retractable mop module stows flush into the chassis underside instead of simply lifting – which means the retraction channel itself becomes a maintenance point that does not exist on earlier robots. A multifunctional dock handles mop washing and debris collection automatically after every session. All components in this generation use the 8.02.0388 consumable family.

This kit is a Plus.Parts® alternative to the original Roborock part, supplying 2 anti-tangle brush sets, 4 side brushes, 6 filters, 4 dust bags and 4 mop pads – 20 parts. Tap the filter out weekly and replace every two to three months; visual replacement cue is a shift from white to consistent mid-grey. The brush bearing seats need a weekly clear in pet homes because the reduced housing clearance on this slim chassis concentrates fibre build-up faster than on full-height Roborock models. Replace dock dust bags every three to five weeks before a full bag causes failed auto-empty cycles. Inspect mop pads at eight weeks and replace when the surface texture has reduced or the pad stays stiff after a dock wash cycle. Monthly attention to the mop retraction channel prevents fibre that accumulates there from restricting the deploy-and-stow mechanism over time.
