What the differences mean

Mopping

The iRobot Roomba Plus 505 mops, washes, dries and lifts the pads, and it self-empties. It does not dose detergent automatically. The Shark PowerDetect Self-Empty does not mop. A Roomba-versus-Shark decision that includes washing the floor is already decided.

Runtime and radios

The iRobot Roomba Plus 505 is rated for 180 minutes, recharges in 4.5 hours, and uses 2.4 and 5 GHz. The Shark PowerDetect Self-Empty is rated for 110 minutes, recharges in 6 hours, and uses 2.4 GHz only. Both return to the dock on their own.

Smart home

The iRobot Roomba Plus 505 supports Alexa, Google Home, Apple Home, SmartThings, Home Assistant and Matter. The Shark PowerDetect Self-Empty supports Alexa, Google Home and Home Assistant, and not Apple Home, SmartThings or Matter.

What the Shark matches

Both use LiDAR, both detect obstacles and cliffs, both map rooms and offer no-go zones, and both self-empty. The Shark PowerDetect Self-Empty is a mapped vacuum, not a random bouncer. Its suction and noise figures are not published.

What owners say

Owners of both talk about pet hair as the reason the robot earned its place, then they describe different upkeep. iRobot Roomba Plus 505 owners single out a fast map and a dock that washes the pads so mixed floors stay on a schedule, and a share say the run, especially the dock cycle, is louder than expected, with glitches that showed up after a few months. Shark PowerDetect Self-Empty owners single out lifting over thresholds and a base they leave for weeks, and they complain about a plain app, Wi-Fi pairing, missed spots, and no mop at all. The Roomba complaint is noise. The Shark complaint is software and the missing mop.
