Front-facing LiDAR — constantly stops and spins to find its place
Shark app is old and lacks features
Noisy; single brush roller gets long-hair wrap
BOTTOM LINE: Is the Shark Navigator RV2120AE Robot Just a Dad Approved?
It IS NOT Just A Dad Approved — this one is a Skip It. The Shark Navigator RV2120AE had real anticipation as a slim, bagless 60-day auto-empty robot, and the dock is a genuine plus. But it doesn't use spinning LiDAR — it has front-facing LiDAR, so it vacuums for a stretch, then stops and spins in a circle to find its place. That's the core frustration. Add an old, hard-to-use app, a noisy robot, and a single brush roller that wraps long hair, and it lands at a 5.5. Skip it — get a Mova P10 Pro or Dreame D20 instead.

When Shark released this robot vacuum there was a lot of anticipation — it was promoted as being really thin. The catch is what's on top: it doesn't have spinning LiDAR, it has front-facing LiDAR. That means the robot vacuums for a while, then stops and spins in a circle to figure out where it is, which gets annoying fast. After three months of testing, the Shark Navigator RV2120AE is a Skip It at 5.5 out of 10.
A quick model note: this is the grey version with the 60-day dock. The white Shark Navigator AV2110S is the same robot with a 30-day dock — other than the dock capacity, they're identical.
What's in the Box and First Setup
Setup runs into the Shark app, which is hard to use and feels old. It lacks features to fine-tune the robot for your home, and that — combined with the constant stop-and-spin navigation — is what held the hassle-free score to a 5 out of 10.
Cleaning Performance: What It Actually Picks Up
Carpet
Carpet cleaning scored a 6 and was lackluster. It does general upkeep but doesn't impress.
Pet Hair
Hair tangle also scored a 6. It carries a single brush roller, so you'll get long-hair wrap. Homes with pets or long hair will struggle with it.
Obstacle Avoidance
Obstacle avoidance scored a 5 — the low point. Because it doesn't have spinning LiDAR, the robot constantly has to stop and spin to relocate itself, and it struggles to avoid objects cleanly in a cluttered room.
The Dock and Maintenance
The headline feature is the bagless auto-empty dock with a 60-day capacity — the robot empties itself and there are no bags to buy. That's a genuine convenience. The robot itself, though, is noisy in use, which is worth knowing if you'll run it while you're home.
App Experience
The Shark app is a weak point: old, hard to use, and short on the features you'd want to customize the robot for your home. There just isn't much to adjust.
What I'd Change About the Shark PowerDetect UV Reveal AV3000XE
Move to spinning LiDAR so it stops having to spin in place to relocate.
Modernize the app and add real customization.
Quiet the robot down and update the single-roller brush that wraps hair.
Frequently Asked Questions
Common Buyer Questions
Is the Shark Navigator RV2120AE worth buying?+
No — it's a Skip It. The bagless auto-empty dock is nice, but front-facing LiDAR that makes the robot constantly stop and spin, a dated app, noise, and a single roller that wraps long hair add up to a robot you can beat at the price. I recommend a Mova P10 Pro or Dreame D20 instead.
What's the difference between the Shark Navigator RV2120AE and the Shark Navigator AV2110S?+
They're the same robot. The only real difference is the dock capacity and color — this grey version has a 60-day bagless dock, and the white Shark Navigator AV2110S has a 30-day dock. Everything else, including the scores, is identical.
Why does it constantly spin?+
It uses front-facing LiDAR rather than spinning LiDAR on top. So it vacuums for a while, then stops and spins in a circle to figure out where it is. It's a real frustration and a big reason for the low ease-of-use score.
Does the Shark Navigator RV2120AE mop?+
No. It's a vacuum-only robot. If you want mopping in this budget range, look at the Mova P10 Pro or Dreame D20 instead.
What should I buy instead?+
I recommend a Mova P10 Pro or a Dreame D20 — better all-around robots with proper LiDAR navigation that don't have to stop and spin to relocate.
