Ranked #7 in Best Robot Vacuums

Shark PowerDetect UV Reveal

3.9

8 sources3 derived$1,219.99as of Aug 23

The Shark PowerDetect UV Reveal represents a significant advancement for Shark in the robot vacuum category, delivering strong vacuuming and obstacle avoidance performance. Its UV stain detection feature automatically enhances mopping when invisible residues are identified. However, the mopping system uses excessive water, leaving floors notably wet and causing prolonged drying times. While it excels in vacuuming and navigation, users seeking balanced mopping performance or advanced app features may find better alternatives.

Strengths

— Strong vacuuming performance with 88% carpet deep clean score
— Outstanding obstacle avoidance, successfully avoiding 20 of 24 objects
— UV stain detection system automatically triggers additional mopping for hidden residues

Watch-outs

— Extremely high water usage, leaving floors significantly wet and causing long drying times over 30 minutes
— Average anti-tangle performance with 29% hair wrap

How they stack up

Roborock Saros 20

The Roborock Saros 20 stands out with its powerful 36,000 pascals suction and self-cleaning dock with boiling hot water mopping, which the Dreame D30 Ultra and Shark PowerDetect UV Reveal lack. However, unlike the Roborock Saros 10R, it doesn't offer the ultra-slim design or advanced 3D navigation, and its heavy base station is a drawback compared to more portable models like the Roomba J7.

Shark PowerDetect UV Reveal

The Shark PowerDetect UV Reveal's standout UV stain detection system is unique among the models, but it uses excessive water, unlike the more balanced mopping of the Ecovacs T90 Pro Omni or the Eufy Omni C28. It also lacks the strong suction of the Roborock Q7 M5+ and Q10 S5+.
