What the differences mean

Mopping

The Roborock Saros 20 mops, washes and dries its mop, refills the water and doses detergent at the dock, while the iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock has no mop or water tank.

Suction

Roborock rates the Saros 20 at 36,000 Pa and iRobot rates the Roomba Max 715 Vac at 30,000 Pa, so the Roborock has more pulling power even before the mop is considered.

Battery

The Roborock Saros 20 is rated for up to 200 minutes per charge against 120 on the iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock, a wide gap for a large floor plan.

Dock

The iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock uses a compact dock rated for about 90 days of debris, while the Roborock Saros 20 uses a large station that also handles water and mop care.

Consumables

The Roborock Saros 20 relies on mop pads, dust bags and a separately bought cleaning solution, while the iRobot Roomba Max 715 Vac Robot + AutoEmpty Dock only needs dust bags, since it never mops.

What owners say

Owners of the Roborock Saros 20 repeatedly single out mapping and the app: it plans a floor in minutes, splits and labels rooms on its own, and makes room-by-room cleaning easy. Suction earns strong praise for pulling dust and pet hair out of hard-floor gaps and off tile, and many note how quiet it is, quiet enough to run overnight. The low-profile body is a recurring highlight, with buyers saying it is the first robot that actually cleans under their furniture, and obstacle avoidance is described as reliable around cables, shoes and pets. The main gripes are that no mop cleaning solution is included even at this price, that threshold climbing is inconsistent on some units, that battery drains faster on deep-clean and carpet runs, and that a few units arrived faulty with slow support.
