What the differences mean

Suction

The Roborock Saros 20 Flow is rated at 36,000Pa against 7,000Pa for the iRobot Roomba 205, so it pulls far more from carpet and embedded pet hair. On bare hard floors the gap narrows.

Mopping

The Roborock Saros 20 Flow mops with a pad that washes, dries and lifts on carpet and doses detergent from the dock. The iRobot Roomba 205 is vacuum-only, so there is no mop to maintain or to wet a rug.

Smart home support

The Roborock Saros 20 Flow supports Alexa, Google Home, Apple Home, SmartThings, Home Assistant and Matter. The iRobot Roomba 205 stops at Alexa, Google Home and IFTTT.

Footprint

The iRobot Roomba 205 charges on a compact base and compacts dust inside the robot, while the Roborock Saros 20 Flow needs a large self-emptying dock. In a small home the Roomba is the easier fit.

Battery runtime

The Roborock Saros 20 Flow is rated for up to 301 minutes per charge against 120 for the iRobot Roomba 205, so it covers far more floor before it recharges. The iRobot Roomba 205 leans on its compactor, which keeps its bin from needing frequent emptying.

What owners say

Owners of the iRobot Roomba 205 value the compact design: the internal DustCompactor presses debris down so the bin needs emptying far less, and the small charging base tucks away where an auto-empty tower would not. Its pickup on carpet and hard floors draws praise, and pet owners say it keeps up with daily shedding. The recurring caveat is battery life, with several owners needing more than one recharge cycle to finish a single level, and a few report it getting stuck on cords, thresholds or small mats. The app also has rough edges, including occasional confusion about whether the robot is docked, and some find the compacted bin awkward to empty.
