Eufy X9 Pro ACS – Plus.Parts® Maintenance Set

The Eufy X9 Pro ACS is the original-branded flagship of the line, carrying the AI.See obstacle-avoidance camera on its front bumper that the plain X9 Pro omits. Everything else is the platform standard: 5,500 Pa suction, twin counter-rotating mop discs at roughly one kilogram of MopMaster pressure and three rotations per second, a twelve-millimetre auto-lift over carpet, and the 40°C Auto-Clean Station. The later Eufy Clean X9 Pro ACS is the same machine under a renamed sub-brand, so this set fits both.

The set provides Plus.Parts® consumables built as a direct-fit alternative to the original Eufy part: two rubber main brushes, four side brushes, four washable HEPA filters and four mop pads. When suction drops on the X9 Pro ACS, work the filter and seals first: tap the filter out and hold it to a light – if light passes poorly through the pleats, replace it whatever its age – then check the 410 ml bin’s lid-seal groove for caked dust and confirm the filter-compartment gasket seats flush. A slightly deformed gasket leaks more airflow than a dirty filter does and is the most-missed cause of a gradual decline. Replace the washable HEPA filter every two to three months and tap it every one to two weeks; rinse under cool water only, and always air-dry before refitting.

Clear the bristle-and-rubber main brush every one to two weeks and replace it every six months; replace the fast-wearing three-blade side brush every two to three months. Treat the mop discs to a hand-wash every four to six weeks and replace the pads about every three months, judging by edge thickness. As an ACS model, wipe the AI.See lens weekly with a dry microfibre cloth – it sits low on the front bumper and catches mop splash and floor dust more than higher-mounted cameras, and a smudge makes the robot over-cautious and slow rather than affecting pickup. Wipe the MopMaster pivot rails every three to four weeks so the carpet lift stays quick, and clean the charging contacts monthly.
