The older robot vacuum wins on the longer run, 220 minutes against 200, slightly larger bins, and the lower price. The Roborock Saros 20 steps up to 36,000 Pa from 22,000 Pa and adds 5 GHz. The body stays 79.8 mm tall, and both mop, self-empty and support Matter. Move up only if that suction or the 5 GHz radio is the point.

What the differences mean

Suction

The Roborock Saros 20 is rated at 36,000 Pa and the Roborock Saros 10 at 22,000 Pa. That is the reason to move up, if embedded dust and pet hair in carpet are the job the older one is not finishing. Everywhere else the cleaning stack is the same shape: a mop, a wash, a dry and a self-empty.

Runtime and the bins

The Roborock Saros 10 runs longer, 220 minutes against 200, and it holds a little more: a 270 ml onboard bin and a 2.7L dock bag, against 259 ml and 2.5L on the Roborock Saros 20. Noise is a wash you would not hear, 64 dB against 63 dB. Both recharge in about 2.5 hours.

5 GHz Wi-Fi

The Roborock Saros 20 joins 5 GHz Wi-Fi. The Roborock Saros 10 does not, and it is the one with Bluetooth documented. Apple Home, SmartThings, Matter, Alexa, Google Home and Home Assistant are on both, so the assistant list does not change. Only the band the phone and the router use might.

Same low body

Both stand 79.8 mm tall, on the same 350 x 353 mm footprint, so moving from the Roborock Saros 10 to the Roborock Saros 20 does not unlock lower furniture. The newer dock is a different box, 381 x 475 x 488 mm, and the robot weight is published only for the newer one, at 5.05 kg.

What owners say

Owners of both Saros robots praise a very low body, quiet overnight runs and obstacle avoidance, then they emphasize different hardware. Roborock Saros 10 owners talk about 22,000 Pa under furniture and a mop that reaches edges and washes itself, and they warn that pads and bags add up and that thicker carpet is the weak surface. Roborock Saros 20 owners talk about 36,000 Pa on embedded dust and pet hair, hot-water mop washing, and a camera they use to check on pets. They complain that deep-clean and carpet runs drain the battery faster, that threshold climbs are inconsistent, and that the mop will not go back over a spot that is still dirty.

Upgrading from the Roborock Saros 10?

Moving from the Roborock Saros 10 to the Roborock Saros 20 buys suction and a radio, not a new kind of robot vacuum. The newer model is rated at 36,000 Pa against 22,000 Pa and adds 5 GHz Wi-Fi, while the body stays the same 79.8 mm height and both still mop, wash, dry, empty themselves and work with Matter, Apple Home and Home Assistant. What you give up is a little runtime, 220 minutes down to 200, and slightly smaller bins. The Roborock Saros 10 is also the more affordable, which is why it still ranks ahead here. Stay if the current one already finishes the house. Step up only for the extra airflow or a 5 GHz network.
