What customers say
Users confirm the Polaris 3900 WMS Assembly immediately restores peak cleaning performance, delivering smooth movement and effective debris collection. This functional success is the core positive takeaway. However, the primary concern centers on value due to the premium pricing of this essential replacement part. While the quality is evident, many feel the high cost is excessive, especially given repeat replacements over the cleaner's lifespan. A smaller group also noted the installation process can present challenges for the average homeowner. Ultimately, the assembly is viewed as a necessary, high-performing fix burdened by a significant financial investment and lingering doubts about its long-term durability relative to its expense.
