R3 Parts in practice

1/5

Wear parts or consumables only

Brand-level (eufy, robot-vacuum). Most comparable old model: RoboVac X8 Hybrid (laser navigation plus mop), presented September 2021. The eufy Spain store (eufy.com/eu-es) sells only its disposable mop cloths (12.99 EUR, in stock), which are a consumable. The X8 Series filter and replacement kit still appear in the accessory list, but their product pages redirect to a collection, so they cannot be ordered. The X8 battery is only on eu-en, marked SoldOut. The older RoboVac 11S (2018) is similar: only the side brush (14.99 EUR) is orderable. Its wheels, rolling brush, filters and brush-motor pages redirect, and its kit is SoldOut. Its battery is sold only on anker.com/de, which is not counted for Spain. Consumables only, so low.
