What changed
newer dock automation and edge coverage • stronger obstacle intelligence

Best move now
Re-check keep versus replace
Out-of-warranty ownership gets more expensive quickly, so this is the moment to pressure-test repair versus replacement.
Selling timing
Tracked resale sits around $680 - $820. Active coverage still adds confidence to that story.

Purchase proof
Receipt-backed purchase is locked in.
Amazon and 1199.00 are supported by uploaded receipt evidence.
Model proof
Model is captured, but proof is still thin.
The model string is stored, but a product label or photo would make it more credible.
Warranty trail
Warranty timing is backed by uploaded proof.
Warranty is tracked through 2026-03-08 with a manual or warranty file attached.
Care history
Future upkeep is scheduled, but completed care is still light.
The schedule exists, but logging real upkeep or replacement proof will make this record more trusted.
