This is the genuine Norsup replacement PVA foam brush assembly for the Cyclone X4 robotic pool cleaner. It includes the PVA foam brush roller (part 370.4), two Delrin washers (part 370.6), and a 413 mm axle \u2014 everything needed to restore your robot’s scrubbing performance in one kit. PVA foam is the soft yet effective material used to dislodge dirt and algae from pool surfaces during each cleaning cycle.<\/p>\n
This PVA foam brush assembly is designed exclusively for the Norsup Cyclone X4 robotic pool cleaner. The soft PVA foam material makes it well suited to concrete, liner, and fibreglass pool surfaces. It is not compatible with Cyclone X2 or other Norsup robot models \u2014 always verify your robot model before ordering.<\/p>\n
Using a genuine Norsup replacement part ensures the brush roller, axle, and Delrin washers are dimensioned to exact factory tolerances. An incorrectly sized or substandard brush can cause uneven wear, reduced cleaning contact, and may void your Cyclone X4 warranty. Genuine parts maintain the cleaning effectiveness that the AquaSmart Gyro System depends on to deliver consistent floor, wall, and waterline coverage.<\/p>\n
The kit supplies all hardware needed for a complete brush replacement: simply remove the worn roller from the existing axle, slide the new PVA foam brush onto the 413 mm axle with the two Delrin washers correctly positioned at each end, and refit the assembly into the robot chassis. No special tools are required, though consulting the Cyclone X4 service manual is recommended to confirm the correct assembly sequence.<\/p>","protected":false},"excerpt":{"rendered":"
