It reaches Apple Home, SmartThings and Matter where the Shark PowerDetect Self-Empty stops at Google Home and Alexa, and it adds a 5GHz Wi-Fi radio the Shark lacks plus a slightly longer runtime. The Shark PowerDetect Self-Empty answers with the lower price and the better owner rating of the two, plus NeverStuck lifting that keeps it from stranding itself on thresholds and rug edges. Both are vacuum-only, both self-empty their bin, and both use LiDAR with obstacle and cliff detection. Buyers already invested in Apple Home or Matter should lean iRobot Roomba Max 705; anyone who wants the better-reviewed machine at a lower price, and does not need those platforms, should pick the Shark PowerDetect Self-Empty.

What owners say

Owners of both vacuum-only robots value that neither one gets stuck, though they praise different reasons for it. iRobot Roomba Max 705 owners who upgraded from an older Roomba call the LiDAR mapping faster and more accurate, and like that the AutoEmpty dock goes weeks without attention, while a recurring complaint is a WiFi setup that rejects router passwords with special characters. Shark PowerDetect Self-Empty owners lean on NeverStuck Technology to explain why it rarely needs rescuing from a threshold or rug edge, and rate its pet-hair pickup highly, but call the SharkClean app basic next to rivals and say the bagless base holds half the debris of pricier Shark models.
