It returns to a base that holds the debris for weeks and adds Home Assistant support, and its owners credit NeverStuck lifting for crossing thresholds and rug edges. The iRobot Roomba 105 is the lower priced of the two and runs a touch longer, 120 minutes against 110, with a faster recharge and a child lock, but its bin has to be emptied by hand after runs. Neither mops, both map rooms with LiDAR, both work with Alexa and Google Home, and both carry a 1-year warranty. Pick the Shark PowerDetect Self-Empty for a shedding pet home where daily emptying is the chore to lose, and the iRobot Roomba 105 to spend as little as possible on mapped vacuuming.

What the differences mean

Self-emptying

This is the difference you live with. The Shark PowerDetect Self-Empty dumps its 189ml bin into a base after each run, while the iRobot Roomba 105 has no base, so a shedding home means emptying the bin by hand every day or two.

Home Assistant

Both work with Alexa and Google Home and neither supports Apple Home, SmartThings or Matter. Only the Shark PowerDetect Self-Empty is listed with Home Assistant support.

Runtime and charging

120 minutes on the iRobot Roomba 105 against 110 on the Shark PowerDetect Self-Empty is a gap you would not notice. The Roomba recharges in 5 hours against 6.

Suction

The iRobot Roomba 105 is rated at 7000Pa. Shark does not publish a figure for the Shark PowerDetect Self-Empty, so the two cannot be ranked on paper.

What owners say

Owners of both robots describe the same win over older machines: LiDAR mapping that cleans in order instead of wandering, and solid pickup of pet hair on hard floors. iRobot Roomba 105 owners single out value for money, saved maps and quieter runs, but many say a larger home needs a recharge partway through, some find it weaker on medium to high pile carpet and a handful report battery or navigation faults after a few months. Shark PowerDetect Self-Empty owners talk about multi-pet homes kept ahead of shedding, a robot that no longer wedges itself under furniture and a base that saves the daily emptying, while their complaints are a plain SharkClean app, registration and Wi-Fi trouble on day one and some missed patches.

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.
