Roborock Saros 20 cleans great—if $1,599.99 fits
Roborock’s Saros 20 delivers strong vacuuming, capable mopping, and a self-cleaning dock, but PCWorld says the price makes it hard to justify.

Roborock’s Saros 20 is exactly what a premium robot vacuum should be: powerful, quiet while cleaning, and packed with automation. According to PCWorld, it performs well on hard floors and rugs, handles mopping reliably, and uses a self-cleaning dock that empties debris and washes its mop pads with boiling hot water. The catch is the price: $1,599.99.
Setup appears straightforward, with a simple quick-start sheet and clearly organized parts. The bigger physical issue is the dock, which PCWorld describes as bulky and heavier than expected.
The app offers extensive controls, though PCWorld found it overly busy. Multi-floor mapping works, but enabling it is not obvious: users need to go to Settings, then Manage Maps, and switch Home Layout to Multi-Level.
Cleaning performance and navigation
The headline specs are high-end: a 6,400mAh battery, 36,000 Pa of suction, and a DuoDivide anti-tangle brush designed to reduce hair wrap. PCWorld said vacuuming is the standout feature, with the Saros 20 cleaning a downstairs floor in about 35 minutes while still finishing with plenty of battery left.
Navigation is driven by an internal lidar system and Roborock’s StarSight Vision Recognition System. The robot reportedly cleaned effectively under a low IKEA coffee table and tracked closely around furniture legs.

It wasn’t flawless. PCWorld said the Saros 20 tried to climb a metal table frame, knocked over a framed picture leaning against a wall, and got caught on a loose charging cord.
Mopping, dock behavior, and whether it’s worth it
The dual mops spin at 200 RPM and automatically lift over carpet. The robot also pauses vacuuming when it detects wet floors. In PCWorld’s kitchen “jelly test,” the Saros 20 removed a streak of red jelly in a single pass without leaving residue.
The robot itself is fairly quiet, but the dock gets loud when it empties dust and washes the mops. PCWorld also noted that the dirty water tank gets grimy quickly—evidence that the mop system is doing real work.
For buyers with a larger home or a bigger budget, the Saros 20 makes sense. For everyone else, PCWorld points to the Roborock Q7 M5+, listed at $299.99 on Amazon, as the more practical option. Its suction is lower at 10,000 Pa, but it still vacuums, mops, and includes a self-emptying base station.
