Quick answer

To install the fragrance refill in your eufy Omni S2, open the fragrance compartment on the top of the robot, insert the refill cartridge until it clicks, and close the lid. Replace it every 2-3 months or when the scent fades. Avoid overfilling or using third-party refills.

What you need

You only need the official eufy Omni S2 Fragrance Refill (Bamboo & Sage or other scent) and your robot vacuum. No tools required. The refill is designed to snap into a dedicated compartment on the robot's top panel, so there is no messy liquid or complex wiring.

When to replace the fragrance refill

The fragrance refill typically lasts 2-3 months with daily cleaning cycles. You'll notice the scent becomes weaker or disappears entirely. The eufy app may also send a notification when the refill is low. Replace it promptly to maintain consistent freshness in your home.

Step-by-step installation guide

  1. Locate the fragrance compartment: On the top of your eufy Omni S2, find the small rectangular compartment with a release tab. It is usually near the front or center of the robot's top shell. Checkpoint: The compartment is not the dustbin or water tank. If you're unsure, consult the user manual.
  2. Remove the old refill (if present): Press the release tab and lift the old cartridge out. Dispose of it properly. Do not attempt to refill the cartridge with liquid or third-party oils. Common mistake: Using non-eufy refills can damage the compartment or cause leaks.
  3. Insert the new fragrance refill: Take the new eufy Fragrance Refill (Bamboo & Sage or your chosen scent) and align it with the compartment slot. Push it in until you hear a click, confirming it is locked in place. Checkpoint: The cartridge should sit flush with the robot's surface. If it protrudes, it is not fully seated.
  4. Close the compartment lid: Gently press the lid down until it clicks shut. Ensure there are no gaps. The lid seals the refill to prevent dust or debris from entering. Common mistake: Forgetting to close the lid fully can cause the refill to fall out during cleaning.
  5. Verify in the eufy app: Open the eufy app on your phone and check the Omni S2 device settings. The fragrance refill status should show as 'Full' or 'New'. If not, reinstall the cartridge. Next step: Run a cleaning cycle to distribute the scent. You should notice the fragrance within minutes.
