What the differences mean

Suction power

The Roborock Saros 20 Flow is rated at 36,000 Pa against 7,000 Pa on the iRobot Roomba 105, one of the largest gaps in this category. On carpet and embedded pet hair the difference is immediate, while on bare floors both keep daily dust under control.

Mopping and dock

The Roborock Saros 20 Flow mops and its dock empties the bin, washes the mop, dries it and dispenses cleaning solution on its own. The iRobot Roomba 105 has no mopping and no self-emptying dock, so both jobs stay manual.

Height and low furniture

The Roborock Saros 20 Flow is 89.8 mm tall, so it reaches under low sofas and toe-kicks that stop the 104 mm iRobot Roomba 105. In a home full of low furniture that decides how much you still clean by hand.

Smart home support

The Roborock Saros 20 Flow supports Matter, which brings it into Apple Home, SmartThings and Home Assistant alongside Alexa and Google Home. The iRobot Roomba 105 stops at Alexa, Google Home and IFTTT, with no Apple Home, SmartThings, Home Assistant or Matter.

Mop maintenance

The Roborock Saros 20 Flow washes and dries its mop and doses its own detergent at the dock, so the pad never sits damp. The iRobot Roomba 105 has no mop at all, which is simpler but leaves hard floors to a separate pass.

What owners say

Owners of the iRobot Roomba 105 describe it as a dependable, budget-friendly vacuum for daily upkeep, with LiDAR mapping that cleans in organized rows, room-specific cleaning from saved maps, and solid pet-hair pickup for the price. Pet owners are its happiest group, often running it between deeper cleans to keep shedding manageable. The recurring caveat is battery life: several owners say it needs a recharge partway through a larger home, and a few report suction weakening on medium to high pile carpet. A handful also describe battery or navigation issues appearing a few months in, usually resolved with a factory reset or a replacement.
