Ecovacs DEEBOT T90 Omni vs Shark PowerDetect ThermaCharged RV2920XE

The top-tier Ecovacs DEEBOT T90 Omni edges past the Shark PowerDetect ThermaCharged RV2920XE in this robot vacuum comparison mainly on staying power: it runs 260 minutes on a charge against the Shark's 180 minutes, and adds Bluetooth to its WiFi where the Shark has no Bluetooth radio at all. Smart home support is actually a wash between them, since both stop at Google Home and Alexa with no Apple HomeKit, Samsung SmartThings or Matter listed. The Shark PowerDetect ThermaCharged RV2920XE pushes back with a longer two-year warranty against the DEEBOT's one year, and a bigger 379ml onboard dustbin versus the DEEBOT's 250ml, on top of its own 185F hot-water mop pad washing that owners rate well. Both are LiDAR robots with self-washing, self-drying mop docks and self-emptying bins, so this comparison comes down to runtime and warranty rather than core cleaning ability. Households that want the longest single run and do not mind the shorter warranty should choose the DEEBOT T90 Omni, while buyers who value extra warranty coverage and a bigger bin between empties may prefer the Shark.
