Full Robot Vacuums comparison in 2026

Updated October 2026
Data from Amazon and official iRobot and Shark sites.
2026 verdict
Mop or self-empty? The iRobot Roomba 105 Combo is the better pick of these two LiDAR robot vacuums for most homes, because it vacuums and mops in one pass and is the lower priced of the two.

It also runs a little longer, up to 120 minutes against 110, and adds a child lock. The Shark PowerDetect Self-Empty answers with the thing the Roomba lacks: a base that empties the bin for you, plus Home Assistant support and NeverStuck lifting that owners credit for crossing thresholds and rug edges. Both map room by room with LiDAR and work with Alexa and Google Home. Choose the iRobot Roomba 105 Combo for hard floors that need a daily mop, and the Shark PowerDetect Self-Empty for a shedding pet home where emptying a bin every day is the chore to lose.

What the differences mean

Mopping

The iRobot Roomba 105 Combo mops hard floors in the same run it vacuums, and it steers around rugs in combo mode. The Shark PowerDetect Self-Empty is vacuum only.

Self-emptying

The Shark PowerDetect Self-Empty returns to a base that empties its bin, so you deal with dust every few weeks. The iRobot Roomba 105 Combo has no such base, and its bin has to be emptied by hand after runs.

Home Assistant

Both work with Alexa and Google Home and neither supports Apple Home or Matter. Only the Shark PowerDetect Self-Empty is listed as working with Home Assistant, which matters if that is where your automations live.

Runtime and charging

120 minutes against 110 is not a difference you would notice. The iRobot Roomba 105 Combo does recharge a little faster, in 5 hours against 6.

What owners say

Owners of both robots praise the same LiDAR navigation, describing methodical room-by-room runs instead of the random bumping of older machines, and both groups say everyday pet hair is handled. iRobot Roomba 105 Combo owners call the mop a helpful bonus on hard floors and like its quiet runs, but many describe a first map that took several runs or manual edits, a combo mode that avoids rugs instead of switching to vacuum only, and a few reliability issues months in. Shark PowerDetect Self-Empty owners single out a robot that rarely gets stuck or wedged under furniture and a base that saves the daily emptying, while their complaints center on a plain SharkClean app, registration and Wi-Fi pairing trouble at setup 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.
