Importance Score: 22 / 100 🔵
Every robot vacuum considered for recommendation undergoes thorough testing at our dedicated facility in Louisville, Kentucky. Our evaluation process includes controlled **pickup tests** on diverse floor surfaces and navigation assessments in a specialized room mimicking a furnished living space to evaluate obstacle course performance. Beyond basic navigation, we scrutinize each robot vacuum’s ability to manage **pet hair** effectively, ensuring minimal clogging and no residual strands. Furthermore, we analyze mopping functionalities and the capacity to navigate around simulated pet messes. This comprehensive approach guarantees our top robot vacuum picks deliver exceptional cleaning and convenience.

Robot Vacuum Cleaning Performance Testing
To assess vacuuming effectiveness, we evaluate each robot vacuum’s performance against both common household crumbs and finer particulates like dust, dirt, and sand. We utilize uncooked black rice as a proxy for larger debris and sand as an analogue for finer particles to simulate these scenarios.
For each test, a precise quantity of each material is distributed across three distinct floor types: low-pile carpet, mid-pile carpet, and hardwood flooring. Low-pile carpet, characterized by its short, dense fibers, generally presents less of a challenge for robot vacuums. Mid-pile carpet, being softer and plusher with taller fibers, typically poses a greater cleaning challenge. After scattering the test materials, the robot vacuum dustbin is thoroughly emptied, and the device is initiated to clean the designated area. Subsequently, we measure the weight of collected debris to determine a pickup percentage. Each test is repeated three times, and the average result is calculated for accuracy.

To streamline our evaluation, we have discontinued black rice testing on hardwood floors due to consistently near-perfect scores across all tested models. Sand now serves as our primary benchmark for assessing cleaning prowess, with a score of 50% or higher considered indicative of good performance.

Long exposure overhead images illustrating the cleaning path of a Roborock S7 MaxV Ultra within our testing room. Glow sticks are affixed atop the cleaner, directly above the vacuum intake, to visualize coverage and navigation efficiency. The S7 MaxV Ultra demonstrates exceptional thoroughness and consistency in room coverage.
Evaluating Robot Vacuum Navigation Capabilities
A robot vacuum’s cleaning efficacy is directly tied to its navigation proficiency within a home environment. An optimal cleaner should effortlessly navigate between rooms and autonomously circumvent obstacles, ensuring efficient and low-maintenance automated cleaning operations.
We meticulously observe each robot vacuum during cleaning cycles to ascertain its navigational aptitude. For standardized comparative assessments, we capture overhead long-exposure photographs of each device operating in a darkened test room. Glow sticks are attached directly above the vacuum intake to trace the cleaning path. Resulting images reveal light trails, visually depicting the robot’s movement pattern as it navigates the room and maneuvers around simulated furniture arrangements.
Contrast this with the subsequent animated image displaying three test runs from the iRobot Roomba Combo J7 Plus. The Roomba exhibits diminished room coverage, failing to reach the bottom-left corner in two out of three attempts and demonstrating limited effectiveness in cleaning around table leg obstacles.
Navigation performance is largely attributed to the underlying technology. Our observations consistently indicate that robot vacuums employing laser-guided LiDAR navigation excel at environmental mapping and spatial awareness. Furthermore, 3D-mapping cameras equipped with object recognition enhance a robot vacuum’s ability to discern and respond to obstacles in its path dynamically. The Roborock S8 Pro Ultra incorporates both LiDAR and 3D-mapping, contributing to its superior navigational performance. Conversely, the Roomba primarily relies on cameras and sensors, omitting laser-based navigation.
The iRobot Roomba J7 Plus effectively avoided simulated pet waste, aligning with its advertised capability.
Nevertheless, camera systems prove invaluable for specific functionalities. Observe the preceding animated image illustrating the iRobot Roomba J7 Plus undergoing pet waste avoidance testing—specifically evaluating its advertised capability to identify and circumvent pet waste. In a confined testing area with simulated dog excrement scattered, the Roomba successfully cleaned the space without contacting any of the artificial waste. It effectively navigated the area, avoiding all simulated pet droppings.
The Samsung JetBot AI Plus consistently failed solid pet waste avoidance tests, invariably colliding with or displacing simulated dog waste in each trial run.
In comparison, the Samsung JetBot AI Plus, which also purports to utilize cameras for pet waste detection and avoidance, yielded suboptimal outcomes. Across multiple test iterations, the JetBot AI Plus invariably collided with the simulated waste piles. Fortunately, the test materials were not genuine.
