iRobot Roomba Plus 505 vs Shark Stratos NeverTouch RV2720ZE

The iRobot Roomba Plus 505 wins overall, and by a wide margin: it comes out ahead on price, battery life, Wi-Fi connectivity and smart-home integrations against the Shark Stratos NeverTouch RV2720ZE.

Smart-home reach is the sharpest gap. The iRobot Roomba Plus 505 supports Apple HomeKit, Samsung SmartThings and Matter alongside Alexa and Google Home, while the Shark Stratos NeverTouch RV2720ZE is limited to Alexa, Google Home and Home Assistant.

Not on the measured specs. Its main differentiator is a sonic-vibrating mop pad, which some buyers may prefer for the cleaning motion, but it does not lead on price, battery life, connectivity or integrations.

Yes, both the iRobot Roomba Plus 505 and the Shark Stratos NeverTouch RV2720ZE have a self-emptying dock that automatically washes and dries the mop pads.

Almost everyone comparing these two: it offers a longer battery runtime, dual-band Wi-Fi, wider smart-home support and a typically lower price than the Shark Stratos NeverTouch RV2720ZE.

Only buyers who specifically want its sonic-vibrating mop pad or prefer the Shark ecosystem, since it does not lead the iRobot Roomba Plus 505 on any measured spec here.
