2026 verdict
The more affordable robot vacuum here is not the weaker one: the iRobot Roomba 705X edges the Roborock Saros 20 Flow on price, owner rating and connectivity.
It adds 5 GHz Wi-Fi where the Roborock Saros 20 Flow is 2.4 GHz only, and it docks with a self-washing roller mop and a 120 minute battery rating. The Roborock Saros 20 Flow is the one with the big number, 36000Pa of suction against the 13000Pa iRobot rates the 705X, in a slim 89.8 mm body. Both mop with a dock that washes, dries and empties, and both reach Apple Home, SmartThings and Matter, so the split is radio and price against raw suction. Choose the iRobot Roomba 705X for the broader radio and the lower price, and the Roborock Saros 20 Flow if maximum suction is the point.

What the differences mean
Suction
Roborock rates the Saros 20 Flow at 36000Pa; iRobot rates the Roomba 705X at 13000Pa. The Roborock figure is nearly three times higher, which matters most on carpet and with heavy debris.
Wi-Fi bands
The iRobot Roomba 705X supports 2.4 GHz and 5 GHz Wi-Fi. The Roborock Saros 20 Flow is 2.4 GHz only, so a router running a single 5 GHz band needs its 2.4 GHz network enabled at setup.
Height and reach
The Roborock Saros 20 Flow is 89.8 mm tall, low enough for furniture the 105 mm iRobot Roomba 705X will not clear, and its dock is smaller on the floor at 381 x 454 x 451 mm.
Battery and recharge
The iRobot Roomba 705X is rated for 120 minutes and refills in about 4.5 hours. Roborock rates the Saros 20 Flow for up to 301 minutes and about 2.5 hours to recharge, so the Roborock covers a larger floor per charge.
Dock and mop care
Both docks empty the robot and wash, dry and lift the mop. The iRobot Roomba 705X empties for up to 75 days; the Saros 20 Flow does not publish an interval but does dose cleaning solution automatically where the 705X does too.
Which one to buy if
- your router is 5 GHz only or you want the newer band
The iRobot Roomba 705X connects on both 2.4 GHz and 5 GHz, while the Roborock Saros 20 Flow is limited to 2.4 GHz.
- you want the highest rated suction
Roborock lists 36000Pa for the Saros 20 Flow against 13000Pa for the iRobot Roomba 705X.
- the robot has to slide under low furniture
The Roborock Saros 20 Flow is 89.8 mm tall, against 105 mm for the iRobot Roomba 705X.
- you want the lower price
The iRobot Roomba 705X is the cheaper of the two and matches the Roborock on Matter, mop care and self-emptying.
