It runs longer at up to 120 minutes against 110, connects over both 2.4 GHz and 5 GHz Wi-Fi instead of 2.4 GHz alone, and reaches Apple Home, SmartThings and Home Assistant through Matter, none of which the Shark PowerDetect Self-Empty supports. Both are LiDAR robots with self-emptying bases and no mopping: the Roomba Max 715 dock holds up to 90 days of debris and the Shark base up to 30. The Shark PowerDetect Self-Empty is the cheaper pick and its NeverStuck lifting clears thresholds well, so buy it if budget leads. Buy the iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock for the longer runtime and the wider smart home support.

What the differences mean

Smart home reach

The iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock supports Matter, which puts it inside Apple Home for Siri control and also inside SmartThings and Home Assistant. The Shark PowerDetect Self-Empty works with Alexa and Google Home, and Home Assistant through its cloud integration, but has no Matter, no Apple Home and no SmartThings.

Wi-Fi bands

The Roomba Max 715 joins either 2.4 GHz or 5 GHz networks. The Shark PowerDetect Self-Empty connects on 2.4 GHz only, which is fine in a simple home but adds a step on combined dual-band routers.

How long the base goes between visits

The Roomba Max 715 AutoEmpty dock is rated for up to 90 days of debris. The Shark PowerDetect base is bagless and uses a HEPA filter, so there are no bags to buy, but it holds up to 30 days, roughly a third of the gap.

Runtime

Up to 120 minutes for the Roomba Max 715 against 110 for the Shark: close enough that it is not the reason to pick either, though the Roomba can cover a little more floor before it returns to recharge.

Which one to buy if

What owners say

Owners of the Shark PowerDetect Self-Empty describe a robot that rarely strands itself and keeps ahead of heavy shedding pets, with NeverStuck lifting it over rug edges and thresholds instead of stopping. Several say its taller body no longer wedges under furniture, and hard-floor households report daily runs replacing most manual sweeping. The repeating complaint is software: the SharkClean app feels basic next to rivals, and a number of buyers hit registration or Wi-Fi pairing errors on the first day. Others report missed patches, or the robot bumping into objects rather than gliding around them.
