Reviews last updated: July 2026 · How we calculate this

What customers like about Shark RV2120AE

  • Excellent anti-tangle system that effectively removes long hair and pet fur from the brush.
  • Bagless self-emptying base saves on maintenance costs.
  • Excellent cleaning ability in corners and on carpets.
  • Very quiet operation during cleaning sessions.
  • Very good value for money at certain price points.

What customers don't like about Shark RV2120AE

  • The SharkClean app is fairly basic and less advanced than competing apps.
  • The obstacle-avoidance system is basic and occasionally inaccurate.
  • Mapping does not support multiple floors.
  • The robot’s dustbin is fairly small.

Verdict

The Shark Navigator RV2120AE is a 650-watt robot vacuum designed for carpets and hard floors, operating on 120 volts and 0.75 amps with a weight of 13.23 lbs and physical dimensions of 17.91 x 12.6 x 14.49 inches. Key characteristics and pros include its Spot LiDAR-driven SmartPath Navigation that enables systematic row-by-row mapping, built-in object avoidance, active Wi-Fi and voice control compatibility via the SharkClean app, an anti-hair wrap self-cleaning brushroll, and a bagless auto-empty dock boasting a 60-day debris capacity alongside a 0.2-quart onboard dust cup. On the downside, the system operates with noticeable noise during cleaning sessions, is physically restricted from mapping multiple floors natively, and requires a prolonged charging time of around 3 hours before starting or resuming tasks.
