Many of these filter replacement kits do not include all required filters. Everything in this set is great for my 11. Good price and parts.
Pros
MAINTENANCE -- It is normal for the side brush to lose its shape and bend during transportation, please just soak the bristles in warm water for a few minutes, they will recover immediately. It is best to replace parts every 2-3 months to keep your Eufy RoboVac 11S in the best working condition. It also depends on your environment and product usage.
