eufy Omni E28: problems, parts and running costs
Checked: 2026-10-17
Summary
The most common complaints about the eufy Omni E28 are a very loud self-empty dock (75-80 dB) and weak fine-debris pickup on carpet, where PCMag measured 20.6% sand removal. Running costs are modest: replacement dust bags are $17.99 for a 3-pack and floor cleaner is $20.99 a bottle. It is a good buy around $600-700 and weak value above $1,000.
Common problems and fixes
- Very loud self-empty dock — the most common owner complaint; it reaches 75-80 dB while emptying, washing the roller or running the spot cleaner, and Tom’s Guide describes a din that lasts about 10 seconds while Gizmodo calls it hellacious. There is no workaround beyond scheduling runs when you are out. [7][5][6]
- Weak fine-debris pickup on carpet — PCMag measured only 20.6% sand removal on carpet against 56.2% on hardwood, and RTINGS judged the E28 inadequate for carpet cleaning. No fix; it is a hardware limit. [3][2]
- Long hair tangles around the brush roll — Vacuum Wars recorded its worst-ever result in a 7-inch hair test, producing dense tangles. Regular cleaning is the only documented mitigation. [4]
- Small 300 ml dustbin — forces frequent trips back to the dock, and RTINGS calls the small dirt compartment high maintenance. [2][4][7]
- Streaky mopping and dirty-water-tank odours — Vacuum Wars measured 1.3 g of water left behind, slightly above average, and owners report streaks on glossy floors and odours from the wastewater tank. [4][8]
- FlexiOne deep cleaner needs the dock unplugged — it shares the dock’s power cable, and its hose can trap water and puddle, risking mould if it is not dried out and disassembled regularly. [6]
- Map and app problems — full functionality needs the eufy Clean app with no on-unit screen; one owner reported the robot forgetting its map and returning to the dock during single-room runs, and another called it riddled with errors and leaks. [10][8]
- Cannot clean under low furniture — it needs a 116 mm (4.37 in) gap, dark carpets may go undetected, and carpets thicker than 26 mm need no-go zones. [1][8]
Parts and consumables
- Replacement dust bags — $17.99 for a 3-pack from eufy, October 2026; one preinstalled bag ships in the box and no spare is included. [3]
- Floor cleaner — $20.99 a bottle from eufy, October 2026, lasting 3-6 months. [5]
- Basic Quarterly Accessory Bundle — $105.94 from eufy, October 2026. [1]
- Complete Maintenance Kit (E28 and E25) — $149.95 from eufy Australia, October 2026. [9]
Yearly running cost
Eufy does not publish a single yearly figure, so the total depends on what you replace. Floor cleaner is $20.99 a bottle and lasts 3-6 months, so two to four bottles a year; dust bags are $17.99 for a 3-pack and the 3 L bag is rated for up to 75 days; Gizmodo expects the mop roller to need replacing about every two months; and the Basic Quarterly Accessory Bundle is $105.94 if you buy it four times.

When it is a good buy
Reviews put the E28 at its best around $600-700, where Vacuum Wars listed it at $629.99 in October 2026 and the obstacle avoidance, carpet deep-clean and integrated spot cleaner outweigh the weak fine-debris pickup and the loud dock. At $800-900 it is fair value if mopping and the spot cleaner matter most. Above $1,000 the case weakens: eufy.com listed it at $1,099.99 in October 2026 and Gizmodo saw a $1,400 street price in January 2026. Buyers who mainly want vacuuming should instead consider the eufy Omni E25 (T2353), which shares the core specs without the portable deep cleaner, or a Roborock or Narwal model for quieter docks and better carpet performance.
