What the differences mean

Mopping

The iRobot Roomba 505X mops, lifts the pads on carpet and lets the dock wash and dry them. Detergent compatibility is listed, without an automatic dispenser. The Shark PowerDetect Self-Empty does not mop. Both self-empty, so the search for a self-emptying robot does not separate them. The separator is whether the same run can leave hard floors damp-clean.

Runtime and charging

The iRobot Roomba 505X is rated for 180 minutes and about 4.5 hours to charge, on 2.4 GHz and 5 GHz Wi-Fi. The Shark PowerDetect Self-Empty is rated for 110 minutes and about 6 hours to charge, on 2.4 GHz only, with no Bluetooth, while the iRobot Roomba 505X lists it. Both return to the dock. A bigger floor shows the 180 minute rating first.

Smart home

The iRobot Roomba 505X lists Alexa, Google Home, Apple HomeKit, SmartThings, Home Assistant and Matter. The Shark PowerDetect Self-Empty lists Alexa, Google Home and Home Assistant, and not Apple HomeKit, SmartThings or Matter. Both can be scheduled. The iRobot Roomba 505X also has a child lock. The Shark PowerDetect Self-Empty does not.

What the base is for

Both self-empty. The iRobot Roomba 505X base also washes and dries mop pads. The Shark PowerDetect Self-Empty base is a bagless vacuum dock, described as holding about 30 days of debris, and its dock capacity is not documented. Suction on the Shark PowerDetect Self-Empty is not documented either, so it is not scored against the 7,000 Pa rating of the iRobot Roomba 505X.

What owners say

Owners of the iRobot Roomba 505X and the Shark PowerDetect Self-Empty both put pet hair at the center of the review, then they describe different machines. iRobot Roomba 505X owners single out a dock that empties, refills and washes pads so the robot can be ignored for long stretches, and they complain the cycle is loud and that the first map sometimes needs a reset. Shark PowerDetect Self-Empty owners single out a robot that climbs thresholds and rug edges and a bagless base they do not dump every day, and they complain about a plain app and a Wi-Fi pairing that fought them on day one. One group is talking about mop upkeep. The other is talking about staying unstuck.
