Eufy Omni C28 vs SwitchBot K11+

The Eufy Omni C28 wins overall, with stronger suction, longer battery life and a self-washing mop system. The SwitchBot K11+ wins on price and smart home integrations, and its much smaller size is a real advantage in tight spaces.

Mopping is the clearest difference. The Omni C28 uses a self-washing, self-drying roller mop, while the SwitchBot K11+ only offers a basic pre-moistened wipe pad with no washing, drying or lifting, so it is light maintenance rather than a true scrubbing mop.

The SwitchBot K11+ is designed for this: its unusually small body and compact dock reach corners, chair legs and low furniture that the larger Eufy Omni C28 cannot access.

The SwitchBot K11+ supports more platforms, including Apple HomeKit, Samsung SmartThings, Home Assistant and Matter. The Eufy Omni C28's listing includes only Alexa and Google Home.

Buyers who want the strongest suction and a genuine self-washing mop system, and who do not need HomeKit, SmartThings or Matter support.

Buyers with tight corners, low furniture or cluttered rooms who want a compact self-emptying vacuum, treat mopping as a light bonus, and want the broadest smart home compatibility.
