Robot vacuums from different manufacturers share the same cleaning goals but use substantially different hardware architectures, navigation systems, and software ecosystems. A fix that works perfectly on a Roomba will not apply to a Roborock — and misapplying it can make the problem worse. Brand knowledge is the most efficient path to a correct diagnosis.
iRobot Roomba divides into three distinct generations with different navigation systems: older 600/700-series use random-bounce iAdapt, 900-series use camera VSLAM, and i/j/s-series use Imprint Smart Mapping with full room recognition. Troubleshooting approach differs by series. Roomba's most common failures are well-documented: the 600-series extractors, the i-series cliff sensor false positives on dark carpets, and the dock alignment sensitivity on s-series.
Roborock's LiDAR-first architecture means navigation problems almost always trace to the LiDAR tower — either obstruction, turret bearing wear, or the tilt sensor inside the unit. Roborock's error codes are among the most informative of any brand and are documented in detail by a large user community. Their app (the Xiaomi Mi Home or native Roborock app) surfaces detailed diagnostic information that most brands hide.
Eufy RoboVac models range from entry-level (BoostIQ random bounce) to AI-navigation models, and the troubleshooting approach is completely different between them. The most common Eufy issue — red charging light — is almost always dirty contacts, not a battery problem. Eufy's support community is smaller than Roomba's or Roborock's, making our guides particularly valuable for these users.
Ecovacs, Shark, and Dreame have grown significantly and now cover the majority of mid-range sales. Each has specific known failure points: Ecovacs OZMO mapping resets, Shark AI camera calibration drift, and Dreame firmware rollout bugs. Our brand guides cover these specifics with tested fixes rather than generic advice.
