What the differences mean

Mop and dock

The Roborock Saros 20 mops, lifts the pads on carpet, washes and dries them, doses detergent and self-empties into a 2.5 L dock bin, with a 4 L water tank. The iRobot Roomba 205 does not mop and does not self-empty. Its maintenance idea is an internal compactor and a small charging base, so there is no tower and no bags, and you still empty the robot yourself. If a washed floor is required, only the Roborock Saros 20 does that job.

Suction and height

The Roborock Saros 20 is rated at 36,000 Pa and stands 79.8 mm tall. The iRobot Roomba 205 is rated at 7,000 Pa and stands 101 mm tall. Both list carpet cleaning and LiDAR. The gap shows up under furniture and in carpet pile: the Roborock Saros 20 reaches lower and pulls harder, while the iRobot Roomba 205 is a taller vacuum-only body.

Runtime

The Roborock Saros 20 is rated for 200 minutes and about 2.5 hours to recharge. The iRobot Roomba 205 is rated for 120 minutes and about 5 hours to recharge. Both return to the dock. Owners of the iRobot Roomba 205 often describe a second charge before a single level is done, which matches the shorter rating.

Smart home

The Roborock Saros 20 lists Alexa, Google Home, Apple HomeKit, SmartThings, Home Assistant and Matter, on 2.4 GHz and 5 GHz Wi-Fi. The iRobot Roomba 205 lists Alexa and Google Home, also on 2.4 GHz and 5 GHz, and not Apple HomeKit, SmartThings, Home Assistant or Matter. The iRobot Roomba 205 lists Bluetooth, which is not documented for the Roborock Saros 20, so it is not scored. Apple HomeKit is a clean reason to take the Roborock Saros 20.

What owners say

Owners of the Roborock Saros 20 and the iRobot Roomba 205 both say pet hair is why the robot earned a place, and both prefer LiDAR to older camera navigation. Roborock Saros 20 owners then talk about dual mops, hot-water washing and a dock they leave alone, plus a low body that gets under sofas. iRobot Roomba 205 owners talk about debris pressed down inside the robot and a small charging base instead of a bagged tower, and they like fewer trips to the trash. Complaints split the same way: iRobot Roomba 205 owners say one charge often fails to finish a floor and that cords or mats stall it, while Roborock Saros 20 owners mention detergent that is not in the box and runtime that drops on a deep carpet pass.

Price history compared
