August 27, 2026, (Inside AI) — The Eufy Omni E28 robot vacuum looks like any other circular cleaning bot. But its dock hides a detachable handheld spot cleaner, a feature that sets it apart in a crowded market. After a month of testing, the device proved highly effective at vacuuming, mopping, and erasing fresh carpet stains.
The FlexiOne Portable Deep Cleaner sits inside the dock. When a spill happens, you pull the handle, carry the unit to the stain, plug it in, and clean before the stain sets. The system mixes water with Eufy’s cleaning solution and sucks dirty liquid back into a reservoir.
This design solves a real problem. Most robot vacuums cannot handle liquid spills. A separate carpet cleaner is bulky and often stored far away. The E28 keeps the tool in a central location, ready for immediate use. That convenience could prevent permanent damage to carpets and furniture.
Stain Test Shows Instant Removal
Testing involved three common staining liquids: iced tea, black coffee, and red wine. Each stain was rubbed into an old carpet runner and left for several minutes. After applying Eufy’s foam solution and waiting another minute, the portable cleaner removed every trace. Once the carpet dried, no discoloration remained.

The robot vacuum itself performed well on hardwood, tile, and carpet. Its LiDAR navigation and RGB camera mapped the home accurately. The app allowed room boundaries and no-go zones. The vacuum used parallel passes and avoided obstacles like socks, toys, and cables.
The CornerRover Arm extends to clean along walls and baseboards. It also reached around table legs. Simulated hairballs and clumps were picked up without tangling the brushes. Pet owners will appreciate this design.
Noise and Drying Cycle Demand Patience
The E28 is not quiet. The vacuum reaches about 74 dB at its loudest. Quiet mode lowers that to 64 dB. The dock’s drying cycle can last up to 5 hours and hums the entire time. Users sensitive to noise should schedule cleaning when away from home.
The LED light is bright enough to help navigation in dim rooms. But it may attract pets or disturb sleep. The dustbin requires disposable bags, adding an ongoing cost. A three-pack costs under $20 and each bag lasts about three months.
The E28 includes a 20,000 Pa suction motor, a 3-liter dust bag, and separate clean and dirty water tanks. Battery life reaches 110 minutes for vacuum and mop, or 180 minutes for vacuum only. It supports Matter, Alexa, Google Assistant, and Siri shortcuts.
At a street price between $600 and $700, the E28 is a mid-range option. The detachable spot cleaner adds unique value for families with kids or pets. The standard one-year warranty covers the device, and the app tracks accessory life.

Inside AI could not independently verify all manufacturer claims. But hands-on testing confirmed the core promise: a robot vacuum with a portable deep cleaner that actually works. For spill-prone households, that combination may justify the price.
