Dreame built the X40 Master around a FlexiArm mop system that actively reaches under furniture and along wall edges, a genuine structural step beyond the telescoping arms of earlier models. At 12,000 Pa of suction, the robot handles embedded carpet debris and hard-floor grit in the same pass, and the auto-washing dock processes mop pads between runs so the robot stays autonomous for days at a time. A robot operating at this level of performance and frequency runs its main brush hard. The contact load accumulates across every session, and the rubber compound softens incrementally until the blade channels that route debris into the suction inlet have widened enough to reduce capture, a gradual degradation that does not announce itself but leaves a measurable mark on cleaning results over a season.
This 3-pack provides Plus.Parts® rubber main brushes built to the X40 Master’s brush housing dimensions and mounting points. Installation requires no tools, no adapters, and no calibration after swapping. Having three in the pack means the robot is immediately back at full performance and the next replacement is already covered.
The compound resists hardening through the full replacement interval. You have invested in one of Dreame’s most capable robots; keeping the main brush fresh is the simplest way to protect that investment. Our team answers fit and order questions directly.
