Eufy Omni C28 vs Shark PowerDetect ThermaCharged RV2920XE

Full Robot Vacuums comparison in 2026

Updated September 2026
Data from Amazon and official Eufy and Shark sites.
2026 verdict
The Eufy Omni C28 wins this robot vacuum pairing clearly, running longer between charges, connecting over Bluetooth as well as Wi-Fi, and typically costing less than the Shark PowerDetect ThermaCharged RV2920XE.
Both robots use a self-washing, hot-water mop system at their dock and share LiDAR navigation with multi-room mapping and no-go zones, so their day-to-day cleaning routines look similar on paper. The Eufy Omni C28 runs up to 251 minutes per charge against the Shark's 180 minutes, and it adds Bluetooth connectivity that the Shark PowerDetect ThermaCharged RV2920XE lacks entirely. The Shark's one real advantage is coverage: it carries a 2-year warranty against the Omni C28's 1 year, which matters if you weight long-term protection heavily; otherwise, the Eufy Omni C28 is the stronger all-round pick for runtime, connectivity and price.
