Its AutoWash dock washes and dries the roller mop, dispenses cleaning solution, empties the bin and lifts the mop over carpet, none of which the Shark PowerDetect Self-Empty can do because it does not mop. The iRobot Roomba 705X also joins 5 GHz Wi-Fi and reaches Apple Home, SmartThings and Matter, while the Shark PowerDetect Self-Empty is 2.4 GHz only, with Alexa, Google Home and Home Assistant. The Shark is the more affordable option, runs a shorter 110 minutes against 120 and takes about 6 hours to charge. Pick the iRobot Roomba 705X for mopping and smart-home reach, and the Shark PowerDetect Self-Empty for vacuum-only simplicity.

What the differences mean

Mopping

The iRobot Roomba 705X mops with a PowerSpin roller and its AutoWash dock washes, dries and lifts the mop and doses detergent. The Shark PowerDetect Self-Empty does not mop at all, so a damp pass is not part of its routine and there is no pad, tank or drying cycle to maintain.

Smart home and Wi-Fi

The iRobot Roomba 705X joins 5 GHz Wi-Fi and lists Apple Home, SmartThings, Home Assistant and Matter alongside Alexa and Google Home. The Shark PowerDetect Self-Empty is 2.4 GHz only, with Alexa, Google Home and Home Assistant, and no Apple Home, SmartThings or Matter.

Runtime and charging

The iRobot Roomba 705X is rated for 120 minutes and charges in about 4.5 hours. The Shark PowerDetect Self-Empty is rated for 110 minutes and takes about 6 hours. The runtime gap is small, but the Shark spends longer on the base between jobs.

Suction

The iRobot Roomba 705X is rated at 13,000 Pa. Shark does not publish a suction figure for the Shark PowerDetect Self-Empty, so the two cannot be measured against each other, and the number should not be read as a proven gap.

Dock jobs

Both self-empty. The iRobot Roomba 705X dock adds clean and dirty water for the mop. The Shark PowerDetect Self-Empty base is dry only and uses bagless HEPA filtration, rated for about 30 days. Neither dock volume is published, and the Shark onboard bin is 189 ml.

What owners say

The only owner reviews behind this pair belong to the Shark PowerDetect Self-Empty, and pet households are its strongest voices. Owners with several dogs and cats describe it keeping ahead of constant shedding and, just as often, refusing to get lost or stranded the way their previous robot did. The taller body is noticed because it stops wedging under furniture, and the bagless HEPA base that holds about a month of debris is liked for not needing bags. Complaints cluster in the software: a SharkClean app described as plain next to rivals, registration and Wi-Fi pairing that fought owners on day one over a 2.4 GHz network, some missed patches, and one report of it bumping objects rather than steering around them.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
