Roborock S8 Max Ultra – Plus.Parts® Maintenance Set

The Roborock S8 Max Ultra raises suction to 8,000 Pa, runs the DuoRoller dual main brush, and adds the FlexiArm extending side brush that swings out to reach corners and skirting. Its multifunction dock empties the bin into a sealed dustbag and washes the mop with 60°C hot water before drying it with warm air.

This set covers the full service scope with Plus.Parts® direct-fit alternatives to the original Roborock parts: two main brush rolls, four side brushes, eight filters, four dock dustbags, four mop cloths and four edge mop pads – 26 parts in all. The FlexiArm side brush is the wear point unique to this model. The extension rail it rides needs a monthly wipe, because grit in the rail adds resistance and stops the arm reaching full extension – the robot then leaves a thin band of dust along corners it used to clear. Beyond that, long hair and thread wrap the brush post and apply a quiet strain to the motor, so check the post weekly and replace the side brush every three to six months.

Tap the filter on all four sides every one to two weeks and replace it every six to eight weeks at 8,000 Pa; do not wash it unless the manual says it is washable. Clean the DuoRoller every one to two weeks and clear the central divider channel at every service – compressed fibre there is the usual cause of a brush stall – and replace the roll every five to seven months. Replace the dock dustbag every three to five weeks rather than waiting for the seven-week rating. On the 60°C dock, wipe the spray nozzles every two to three weeks in hard-water areas so mineral scale does not block one side and leave the mop half-cleaned, empty the dirty-water tank every two to three days, and wipe the warm-air drying vent monthly. Inspect the mop pads at six to eight weeks. Behind the set is a real team at VacuumReviews.eu, so if the arm stops reaching corners or one mop edge stays dirty, reach out and we will help you sort it.
