Showing Uninell UR3 Robot Vacuum and Mop

Answer First

The Uninell UR3 is a LiDAR-guided robot vacuum and mop with a 3.5L self-emptying station, 5000Pa suction, and a long 180-minute runtime. I tested it in a real home with mixed floors, two pets, and everyday day-to-day clutter.

It vacuumed well, navigated with precision, and emptied itself reliably. The mop is basic but useful for daily dust. It performs close to higher-priced units from Roborock and Roomba, but at a lower cost. It suits busy users, pet owners, and anyone needing hands-free floor upkeep.

My findings below are based on actual tests, logged data, and measurable results.

Tips Liam Verdict

The UR3 exceeded my expectations as an electrical engineer who is naturally skeptical of budget smart devices. It delivers strong suction, quiet operation, accurate LiDAR mapping, and consistent self-emptying performance.

It is not a deep-scrubbing mop or a premium robot with AI cameras, but it offers excellent hands-free vacuuming for the price.

Overall Rating: 4.5/5. | $259.99 at Amazon

Why We Tested Uninell UR3 Robot Vacuum

Many readers asked whether low-cost LiDAR robot vacuums are worth buying. The UR3 appeared frequently in search trends, especially among pet owners and first-time robot vacuum buyers. People wanted clarity on real suction, mapping accuracy, noise levels, and mopping limitations.

As engineers, we test devices to validate claims, quantify performance, and give honest guidance. My goal was to confirm whether this unit could replace manual vacuuming for routine cleaning—without marketing gloss.

Design and Features

Close look at the Uninell UR3 vaccum Design and Features

As an engineer, I care less about aesthetics and more about function. The UR3 balances both.

Compact Form Factor: At 3.8 inches tall, it fits under most sofas and beds. Not ultra-slim, but within practical limits for LiDAR robots. The LiDAR turret adds height but enables precise navigation.

Self-Emptying Dock: The dock is practical and stable. After each run, the robot aligns and empties into the 3.5L sealed bag. This mattered to me—I prefer dust sealed rather than dumped into a plastic cylinder that puffs debris back into the room.

Control Options

You can operate it through:

  • Smartphone app
  • Physical buttons
  • Voice commands
  • Included remote

The remote is rare in this price class and helpful for older users who avoid apps.

Vacuum System: The 5000Pa suction is supported by a unified rubber-bristle main brush. During my tests, it picked up debris without the brush choking on hair, which was a pleasant surprise. Side brushes push debris inward effectively.

Mopping System: The mop attaches with a simple slide-and-lock. Water control is software-driven. It is a maintenance mop—not a replacement for manual scrubbing.

Sensors: Underside cliff sensors protected it from stairs. IR sensors helped it slow before bumps. It’s not an AI robot that identifies objects visually, but the LiDAR compensates by preventing chaotic navigation.

How Uninell UR3 Robot Vacuum Works — Core Mechanisms Explained

Uninell UR3 Robot Vacuum working principle

LiDAR Navigation: The robot builds a live map through rapid laser scanning. You see the map update in the app in real time. I watched it move in clean, predictable lines—not random bouncing—which indicates proper SLAM (Simultaneous Localization and Mapping) implementation.

Self-Emptying Process: When it docks, a high-velocity channel at the base pulls debris from the internal bin into the 3.5L bag. In my home, the transfer was complete each time. The internal bin stayed clean, which reduces clogging risk.

Vacuuming Logic: The UR3 adjusts its suction when it detects carpet. You can hear a slight pitch change in the motor as it increases power. The brush agitates debris while the suction pulls particles up. The airflow path is short, which improves pickup efficiency.

Mopping Logic: Water drips through a controlled valve onto a microfiber pad. The robot drags the pad across the floor. This is suitable for dust, paw prints, and spilled dry debris. It cannot lift dried stains because it lacks downward force.

Battery Management: It returns to charge at ~15% and resumes autonomously when charged to ~80%. This behavior worked reliably during my large-area tests.
