Two of our picks from Best Robot Vacuums, compared side by side on the specs and trade-offs that actually matter.
Short answer
Between the Shark PowerDetect UV Reveal 2-in-1 and the Roborock Saros 20, we recommend the Shark PowerDetect UV Reveal 2-in-1 ($849.99 when we checked it on 2026-08-10) as the better robot vacuum for most people. Pet owners who want the strongest all-around cleaner of the bunch. The Roborock Saros 20 ($1599.99 when we checked it on 2026-08-10) still makes sense if multi-level, threshold-heavy homes with pets and low furniture.

Our take on each
Roborock Saros 20
Best for: Multi-level, threshold-heavy homes with pets and low furniture.
The Saros 20 is about raw capability, full stop. Its 36,000 Pa motor pulls pet hair out of deep floor gaps that lower-suction robots simply pass over, which is exactly why it is the pick here for pet hair.
The AdaptiLift chassis climbs thresholds up to 3.46 inches without bogging down, and at just over three inches tall it slips under sofas and low furniture most robots cannot reach at all. StarSight navigation maps the space accurately and dodges obstacles rather than blundering into them.
It is the costliest pick here and its 180-minute runtime is the shortest of the three, so it may need a mid-clean recharge in a larger home. For multi-level, threshold-heavy houses with pets, though, it is also the most genuinely capable machine of the group.
Shark PowerDetect UV Reveal 2-in-1
Best for: Pet owners who want the strongest all-around cleaner of the bunch.
The Shark earns its keep with sensing smarts rather than brute force alone. PowerDetect reads debris and floor type on the fly and adjusts as it goes, while the UV Stain Detect light literally reveals dried-on pet messes so it can target them instead of driving past.
It earns the overall pick here because the sensing does work the other two leave to brute suction: PowerDetect and UV Stain Detect are both aimed at finding the mess rather than covering more floor. The ThermaCharged base empties, refills and washes the mop with hot water for up to 60 days hands-free, which is the part that actually changes how much you think about vacuuming.
The honest downsides are that it is still a premium-priced machine and the heaviest unit here at nearly 27 pounds. For households with pets, though, it is the easiest one to recommend.
