How to Clean a eufy Robot Vacuum Omni E28

The eufy Robot Vacuum Omni E28 combines a robot vacuum, HydroJet roller-mop system, self-emptying and mop-washing station, plus the E28-only FlexiOne portable deep cleaner. Those systems create three separate dirt paths: dry debris through the dustbin and dust bag, floor-washing water through the roller mop and station tanks, and upholstery-cleaning solution through the portable cleaner. eufy's E25/E28 maintenance guidance calls for regular cleaning of filters, brushes, roller mop, sensors, tanks and tray, while app prompts track replacement intervals. The robot and station must be powered down before manual service, and washed components must be fully dry before return to a suction or electrical path.

What you will need

  • The eufy Omni E28 User Guide for model T2352
  • The supplied cleaning brush or tool
  • Clean running water
  • Clean dry microfiber cloths
  • A soft brush for sensors and dry debris
  • Small scissors for wrapped hair
  • A ventilated rack for washed parts
  • Compatible dust bags, filters and wear parts when replacement is due

Step-by-step instructions

Step 1: End the task and isolate power

Return the robot, end cleaning in the app, switch the robot off and unplug the Omni station before manual maintenance. Remove the E28 portable deep cleaner from its dock only after the system stops. Keep tank water away from plugs, charging contacts and the station interior.

Step 2: Empty and clean the station tanks

Remove the dirty-water tank first so it cannot spill while other parts are handled. Empty it promptly, rinse the tank, lid, float and user-removable filter, and brush away film. Rinse the clean-water tank separately. Use only eufy-approved solution and never mix bleach, vinegar or foaming detergent in the system.

Step 3: Clean the station tray

Remove the cleaning tray as the user guide shows, discard hair and sludge, rinse approved removable sections and wipe the station cavity rather than pouring water into it. Dry metal detector or contact areas. Reinstall the tray level and fully seated; a dirty or missing tray can trigger wastewater errors.

Step 4: Service the robot dustbin and filter

Open the robot, remove the dustbin and empty debris. Tap the filter gently, then wash the dustbin and filter under running water only if the E28 guide marks both washable. Air-dry completely before assembly. A clogged filter causes weak suction; a damp one can carry moisture toward the fan.

Step 5: Remove DuoSpiral roller debris

Release the brush guard and lift out the roller brushes. Pull away hair and thread, using small scissors without cutting rubber or bristles. Clean both end areas and the accessible cavity. Wash only components eufy identifies as washable, dry them and snap the rollers and guard back into their keyed positions.

Step 6: Clean side brushes, wheels and sensors

Remove wrapped hair from side brushes and axles, and turn each wheel by hand while the robot is off to free accessible debris. Wipe cliff, wall, obstacle and charging sensors with a soft dry cloth. Do not wet the laser module, camera or charging contacts and do not remove wheel modules.

Step 7: Clean the HydroJet roller mop

Use its release to remove the roller mop and inspect the roller and bracket. Rinse the user-removable mop under clean water, clear hair or hardened debris from its ends and clean the bracket as shown. Dry before reinstalling until it clicks. Persistent poor mopping can result from debris in either the roller or bracket.

Step 8: Check the station dust bag and airway

Open the dry dust-bag compartment away from wet tanks. Replace a full bag rather than emptying or washing it. Check the bag opening, robot dust outlet and accessible station inlet for a blockage, using a dry tool. Keep wet cloths and tank drips out of the auto-empty path.

Step 9: Clean the FlexiOne portable deep cleaner

After upholstery or spot cleaning, empty the portable cleaner's dirty-water reservoir and rinse user-washable tanks and tool parts. Remove lint from the brush head; eufy identifies a dirty head as one cause of poor extraction. Wipe the powered body and connectors, and never use the dense brush on fragile or valuable fabric without the recommended test.

Step 10: Dry, reassemble and reset maintenance

Air-dry filters, dustbin, tanks, tray, roller mop, brushes and portable-cleaner wet-path parts. Reinstall every float, filter, cover and latch before restoring station power. Run the app's roller self-cleaning cycle when appropriate and reset a maintenance counter only after the part was actually cleaned or replaced.

Specific cleaning questions

Open a question for a concise answer about stains, odors, safety, frequency, and troubleshooting.

Can I wash the eufy Omni E28 filter?
Wash it only as the E28 guide directs, then air-dry it completely before reinstalling. A damp or clogged filter can reduce suction and expose the fan to moisture.
How do I clean the E28 HydroJet roller mop?
Release the roller, rinse the removable mop, clear debris from its ends and bracket, dry it and reinstall it until it clicks. Inspect the bracket when mopping remains weak.
Why does my E28 report a wastewater extraction error?
The dirty tank, seal, tray or mop-washing path may be misseated or dirty. Empty and clean the tanks and tray, dry detector areas, dock fully and run roller self-cleaning as eufy directs.
Can I wash and reuse the eufy station dust bag?
No. Replace a full disposable dust bag. Keep its compartment and the auto-empty airway dry.
How do I clean hair from E28 DuoSpiral brushes?
Power off, remove the brush guard and rollers, cut wrapped hair carefully and clear the end areas and cavity. Reinstall each roller in its keyed position.
What cleaner can I put in the Omni E28?
Use only solution eufy approves for the E28 and its specified amount. Foaming detergent, bleach, vinegar and unapproved concentrate can damage pumps or leave residue.
How do I clean the E28 portable deep cleaner?
Empty its dirty reservoir, rinse approved wet-path pieces, remove lint from the brush head, wipe the powered body and dry every part before docking.
How often should I clean an Omni E28?
Empty dirty water after wet tasks, inspect brushes and roller mop weekly in a busy home, clean sensors and tray when visibly soiled and follow app prompts for filters and wear parts.
