Compatibility check 1: floor type and threshold height
For robot vacuums, record the exact value, standard, measurement, or supported condition behind floor type and threshold height before checkout. A broad category label does not prove that the selected variant fits. Confirm the manufacturer, complete model, hardware revision, electrical rating, protocol, controller support, included parts, and region rather than assuming similarly named products share limits.
Compatibility check 2: pet hair and obstacle avoidance
Test pet hair and obstacle avoidance across the actual fixture, circuit, controller ecosystem, radio path, owner account, and manual fallback—not a product-photo setup. If this robot vacuums fit depends on a neutral wire, hub, bridge, account, subscription, compatible controller, professional installation, or reliable cloud service, confirm the exact part, service, or behavior as part of compatibility.
Compatibility checks 3 and 4: mapping, room control, and privacy; bin, dock, bag, and brush maintenance
For robot vacuums, mapping, room control, and privacy and bin, dock, bag, and brush maintenance are the limiting conditions most likely to surface only after installation. Measure the smallest clearance, weakest connection, least compatible user or device, and the most demanding normal task. Passing an ideal bench test is not enough.
Prove fit in a reversible order
Use this sequence: remove hazards, map one floor, block cables and fragile areas, run while present, then schedule only after observing where it sticks. Keep labels, packaging, manuals, and the previous system until the product works through normal use and a recovery test. Photograph wiring, measurements, or assembly states that would be difficult to reconstruct.
A failed fit check is a stop signal
Stop when the home has unsafe cords, pet waste risk, steps or thresholds it cannot navigate, or manual vacuuming is faster than preparing and rescuing it. Do not repair a fundamental mismatch with unapproved accessories, copied settings, or community anecdotes. Use cordless vacuums when it meets the job with a clearer compatibility path.
