Frequently asked questions
Can I use parts from another Eufy model on the Omni S2?
Some dock bags fit multiple models in a range, but brushes and filters may differ. Check the compatible-model list for the exact part.
Are third-party parts okay to use?
They can be an option when a listing names your exact model. Compare dimensions, seller information, and return terms.
How often should I replace the filter?
Inspect it regularly. A six to twelve month interval is a planning estimate; usage and manufacturer guidance should decide.
