Roborock Saros 20 vs Shark PowerDetect UV Reveal
Two of our picks from Best Robot Vacuum and Mop Combos in 2026, compared side by side on the specs and trade-offs that actually matter.
Short answer
Between the Roborock Saros 20 and the Shark PowerDetect UV Reveal, we recommend the Roborock Saros 20 ($1599.99 when we checked it on 2026-10-19) as the better robot vacuum and mop combos in 2026 for most people. Homes with raised thresholds, low sofas and long-haired pets, where cheaper robots get stuck or leave rooms unreached. The Shark PowerDetect UV Reveal ($1179.99 when we checked it on 2026-10-19) still makes sense if pet owners with mixed carpet and hard floors on one level who want the base to handle the mop pad for weeks at a time.

Our take on each
Roborock Saros 20
Best for: Homes with raised thresholds, low sofas and long-haired pets, where cheaper robots get stuck or leave rooms unreached.
The Roborock Saros 20 is the pick when the floor plan is the hard part. Its AdaptiLift chassis raises the body to climb double-layer thresholds up to 3.46 inches, which covers the door strips and rug transitions that stop most robots. At 3.13 inches tall it is the slimmest robot here by more than an inch, so it reaches under beds and sofas the Dyson cannot.
Roborock rates the motor at 36,000 Pa, double the Dyson figure, with a dual anti-tangle system for long hair. Navigation pairs 3D time-of-flight sensors with an RGB camera for obstacle avoidance, and a FlexiArm pushes the side brush and mop into corners.
The RockDock washes the dual spinning mops in 212°F water, dries them, and empties the robot. The mops detach and stay in the dock for vacuum-only runs. The costs are real: $1,599.99 at our last check, the top of a $1,299.99 to $1,599.99 range, and a rated runtime of 180 minutes against the Dyson's 200. It also has the most retailer reviews of the three, 4,507 at a 4.2 average.
Shark PowerDetect UV Reveal
Best for: Pet owners with mixed carpet and hard floors on one level who want the base to handle the mop pad for weeks at a time.
The Shark PowerDetect UV Reveal is the all-rounder of the three. It vacuums and mops in one run, adjusts to floor type and debris level as it goes, and uses a UV light to show dried pet accidents and sticky spills that a normal camera passes over. Shark claims up to 3 hours of runtime on bare floors, and the robot recharges and resumes on its own if a large home needs more.
The base does the most work of any dock here. It empties the bin, refills the robot, washes the mop pad with 185°F water and dries it with 175°F air, with HEPA filtration in the base. Shark rates that for up to 60 days without attention. A UK review measured a 2.75 liter clean tank and a 1.5 liter dustbox and found the 60-day figure optimistic.
The drawbacks are noise and polish. Reviewers describe it as louder than rivals, and the UK review reported the app storing only one map, which hurts multi-story homes. At about 4 inches tall it sits between the Roborock and the Dyson. The price has ranged from $749.99 to $1,299.99 in our tracking.
