Updated October 2026

The 705X is rated at 13,000 Pa against 7,000 Pa, empties itself for up to 75 days and washes, dries and doses its mop, and it supports Apple Home, SmartThings and Matter. The iRobot Roomba 205 takes the other route: it is vacuum only, but its internal DustCompactor presses debris down so its bin lasts longer, and it pairs with a tiny charging base instead of a full tower. Pick the iRobot Roomba 705X for mopping and broad smart home support, and the iRobot Roomba 205 if you want compact, vacuum-only cleaning with no bulky dock.

What the differences mean

Mopping

The iRobot Roomba 705X vacuums and mops, with a roller the dock washes, dries and doses. The iRobot Roomba 205 has no mopping hardware.

Dock versus compactor

The iRobot Roomba 705X self-empties into a full AutoWash dock that also cares for the mop. The iRobot Roomba 205 uses an internal DustCompactor and a small charging base, so there is no tower and no bags, but the bin is still emptied by hand.

Suction

The iRobot Roomba 705X is rated at 13,000 Pa and the iRobot Roomba 205 at 7,000 Pa, a clear edge on thick carpet and pet hair.

Smart home support

The iRobot Roomba 705X covers Alexa, Google Home, Apple Home, SmartThings, Home Assistant and Matter. The iRobot Roomba 205 covers Google Home, Alexa and IFTTT only.

Dock footprint

The iRobot Roomba 205 charging base is roughly 213 x 170 x 282 mm. The iRobot Roomba 705X AutoWash dock is about 457 x 429 x 432 mm, so the 205 needs far less floor space.

Which one to buy if

What owners say

iRobot Roomba 205 owners chose it to escape the bulky auto-empty tower, and they say the internal DustCompactor works: the bin needs emptying far less often and the small charging base takes up almost no space. Pet households report it clears dog and cat hair from carpet and hardwood between deeper cleans, and the LiDAR mapping draws praise for being quiet and accurate, even in the dark. The recurring complaint is battery, with several owners needing two or more recharge cycles to finish a single floor. Others mention getting stuck on cords, thresholds or small mats and an app that sometimes misreads whether the robot is docked.
