All robots · as of June 2026
Gentle deflation overall — supply of nearly-new units is growing faster than demand, which favours buyers.
New-model launches each spring push last year's flagships down ~6% — the classic upgrade-cycle discount.
Strongly seasonal: prices bottom in November and peak in April–May. Buy your mower in winter.
Sub-250 g models hold value best; full-size camera drones depreciate faster on new releases.
The fastest-deflating segment — relentless new-model pace. Excellent news for first-time makers.
The exception: demand outruns supply and early humanoid allocations carry a scarcity premium. We expect this to normalise as production scales.
Per-model price data, depreciation rates, and what to check before you buy.
The Index tracks achieved prices — what robots actually sell for, not what they're listed at — across a fixed basket of 62 models, weighted by transaction volume. Condition is normalised to “Excellent” using our grading model; battery health below 75% is excluded from the basket. Grey line on segment charts shows the all-robots index for comparison.
The Robot Resale Index is the UK's first price index for second-hand robots. It tracks achieved sale prices — what robots actually sell for — across a fixed basket of 62 models in six market segments: vacuums, mowers, drones, 3D printers, advanced robotics, and commercial robots. Rebased to 100 in July 2025 and updated monthly.
The index is built from achieved transaction prices from verified listings, normalised to Excellent condition using Robot AutoTrader's grading model. Battery health below 75% is excluded. Models are weighted by transaction volume. A segment index reading of 95 means robots in that category are selling for 5% less than at the July 2025 baseline.
Advanced and humanoid robotics is the only category where prices are rising — the Unitree Go2 Pro is up 18.4% year on year. Robot vacuums and mowers depreciate at 6–12% per year. Drones and 3D printers depreciate fastest due to rapid model cycles from DJI and Bambu Lab.
