Dock stopped emptying dust into bag; warranty voided after claim

Dock auto-empty system

Retailer reviewIndexed Oct 9, 2026Source-linkedVerify source — Alza review

[Translated from Czech] Alza verified review by Lukáš, Svojšice (2026-05-25). After some time the S8 MaxV Ultra dock stopped vacuuming dust from the robot into the bag. Warranty claim returned saying no fault found and alleged unauthorized intervention, voiding paid extended warranty. Unit remains unable to perform auto-empty.
