Score breakdown
Why this grade
iRobot sells official user-replaceable modules (battery, brushes, wheel modules, cleaning head modules, faceplates) through irobot.com plus official step-by-step replacement instructions on homesupport.irobot.com; large aftermarket and iFixit guides exist. Roombas are deliberately modular with standard fasteners, making them among the more repair-friendly robot vacuums. OEM batteries are noted as expensive (cheap aftermarket batteries widely available). App/cloud dependency exists for some features, but parts are NOT serialized or paired, so battery/brush swaps are not software-gated. Equal-weighted avg ~76.
Methodology & version
Five dimensions — parts availability, schematic access, repairability, OEM pricing, and software freedom — are scored 0–100 and weighted equally; the letter grade is the average (A 90–100, B 80–89, C 70–79, D 60–69, F below 60). This assessment is current as of 6/9/2026 and cites its sources below. It covers the Small appliances category and is not a claim about every device the maker ships.
