Deep Clean: Best Robot Vacuums for Thick Carpets

Navigation technology is crucial for efficient cleaning, especially on thick carpets where precise movement is necessary to ensure thorough dirt extraction. The iRobot Roomba Combo j9+ utilizes PrecisionVision Navigation with VSLAM, offering camera-based object recognition and avoidance. In contrast, the Roborock models, including the S8 Pro Ultra and Q5 Pro+, leverage PreciSense LiDAR navigation, providing systematic route planning and quick mapping capabilities. The eufy X10 Pro Omni stands out with its AI.See™ Smart Avoidance, combining RGB camera and LED for superior obstacle detection, even in low-light conditions. These navigation systems vary in their ability to handle complex environments, with LiDAR systems generally offering faster mapping and more detailed room segmentation. Key considerations include the ability to store multiple maps and the effectiveness of obstacle avoidance.

Suction power is a critical factor in determining a robot vacuum's ability to deep clean thick carpets. The eufy X10 Pro Omni leads with an impressive 8,000 Pa suction, ensuring it can lift embedded dirt and debris from dense fibers. The Roborock S8 Pro Ultra follows with 6,000 Pa HyperForce Suction, while the Q5 Pro+ offers a respectable 5,500 Pa. The iRobot Roomba Combo j9+ does not disclose its suction in pascals but claims 100% stronger suction than its i-Series counterparts. These differences in suction power affect the vacuum’s ability to handle varying carpet densities, with higher suction models typically providing more thorough cleaning on thicker carpets. Additionally, features like Carpet Boost, found in all models, automatically increase suction when carpets are detected.

The convenience of maintenance is a defining feature of modern robot vacuums, with many models offering automated solutions to minimize user intervention. The Roborock S8 Pro Ultra's RockDock Ultra stands out by handling emptying, washing, drying, refilling, and self-cleaning, making it an ideal choice for those seeking a hands-off experience. The eufy X10 Pro Omni's Omni Station also provides similar automated maintenance, including mop washing and drying. The iRobot Roomba Combo j9+ features a Clean Base Auto-Fill Dock, which empties debris and refills water but requires manual mop pad washing. In contrast, the Roborock Q5 Pro+ offers basic self-emptying without mop washing or refilling capabilities. These maintenance features significantly impact long-term usability and efficiency, particularly in larger homes.

Mopping capabilities add versatility to robot vacuums, especially for homes with mixed flooring. The Roborock S8 Pro Ultra employs VibraRise 2.0 Sonic Mopping, offering dual vibration modules that scrub at 3,000 times per minute for effective stain removal. The iRobot Roomba Combo j9+ features a SmartScrub System with back-and-forth motion, while its Auto-Retract Mopping System ensures carpets remain dry. The eufy X10 Pro Omni's MopMaster™ 2.0 lifts mops 12mm, providing superior protection for medium-pile carpets. The Roborock Q5 Pro+ offers a basic mopping module without lifting capabilities, making it less suitable for homes with extensive carpeted areas. The choice of mopping system affects cleaning efficiency and the ability to transition seamlessly between different floor types.
