What the differences mean
Mop dock versus a vacuum
The Roborock Saros 20 mops, doses detergent, washes and dries the pads, lifts them and empties into a 2.5L bag, with a 4L water tank. The iRobot Roomba 105 does none of that. It vacuums, and you empty the bin. If a damp floor is part of the job, the Roomba is the wrong robot in this pair.
Suction and runtime
The Roborock Saros 20 is rated at 36,000 Pa for 200 minutes and recharges in about 2.5 hours. The iRobot Roomba 105 is rated at 7,000 Pa for 120 minutes and takes about 5 hours to charge. That is not a small step. It is a different class of airflow, which is also why the prices sit so far apart.
Matter and 5 GHz
The Roborock Saros 20 supports 5 GHz Wi-Fi, Apple Home, SmartThings, Matter and Home Assistant, plus Alexa and Google Home. The iRobot Roomba 105 supports Alexa and Google Home on 2.4 GHz only. It does not support Apple Home, SmartThings, Home Assistant or Matter. The assistant list is as far apart as the suction.
Weight and height
The iRobot Roomba 105 weighs 2,790 g and stands 104 mm tall. The Roborock Saros 20 weighs 5.05 kg and stands 79.8 mm tall. The Roomba is the one you can pick up easily. The Roborock is the one that fits under lower furniture, and it brings a dock that weighs 10.54 kg and needs a permanent spot.
Which one to buy if
- you only vacuum and want the lower spend
The iRobot Roomba 105 maps with LiDAR at 7,000 Pa and skips the mop dock entirely. It is the affordable robot vacuum in this pair.
- floors need mopping and a dock that keeps up
The Roborock Saros 20 washes, dries, lifts and empties. The iRobot Roomba 105 does not mop and does not self-empty.
- you need Apple Home, Matter or 5 GHz
The Roborock Saros 20 has all three. The iRobot Roomba 105 has none of them, and it stays on 2.4 GHz with Alexa and Google Home.
- the robot has to slide under a low sofa
At 79.8 mm the Roborock Saros 20 is much shorter than the 104 mm iRobot Roomba 105, even though the Roomba is lighter.

What owners say
The owner stories barely overlap, because the products barely do. iRobot Roomba 105 owners praise LiDAR rows instead of random bouncing, everyday pet hair on hard floors for the money, and a bin they empty less often than a tiny one. They complain that larger homes need a mid-run recharge, and that medium and high pile gets a weaker pass than hard floors. Roborock Saros 20 owners praise 36,000 Pa on embedded dust, a body that slides under sofas, a quiet night run, and hot-water mop washing. They complain about price, detergent sold separately, threshold climbs that miss, and a battery that falls off during a deep carpet clean.
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.
