what experts say
- >“The UV Reveal is Shark's brand-new robot vacuum, and the name gives away its flagship feature: a built-in UV light to spot stains that would otherwise go unnoticed. It's a feature that makes me question if any robot vacuum I've had before was actually doing a good job.”— WIRED
what the community says
- >“Does a great job both vacuuming and mopping. Stain Detect is handy and pretty consistently spots stains. Works fairly fast. Does a good job in corners.”— WIRED reviewer
