Greenworks Optimow 33H vs TerraMow V1000

Pros & cons
Greenworks Optimow 33H
- ✓High-cut 2.4-4.0 in range is right for fescue and bluegrass
- ✓4G plus GPS built in, so the app works away from home Wi-Fi
- ✓Proven wire-and-guide-wire platform with a wide dealer network
- ✓Long consumer warranty on the Optimow line
- ✗Dealer-only and sold out online; pricing and stock vary by dealer
- ✗GreenGuide app draws consistent complaints from Optimow owners
- ✗Cellular plan renews for a fee after the prepaid period
- ✗No edge mode and no camera obstacle avoidance
- ✗Random pattern and 130-minute charges make it slow on a full third acre
TerraMow V1000
- ✓Genuinely no-infrastructure setup: it explores and maps the lawn on its own in one run
- ✓Owners report virtual fences work well for shared lawns and irregular borders
- ✓Quietest mower in this batch at under 54 dB, so early-morning runs are fine
- ✓Mows offline from a stored map; 20 zones across 3 maps and an edge mode in the app
- ✓3-year warranty and a 4G module with the first year of data included
- ✗Only 160-300 square meters per charge from the 4.5 Ah battery, so big lawns mean many cycles
- ✗33 percent (18 degree) slope limit rules out hilly yards
- ✗Camera navigation needs daylight; no night mowing
- ✗Owners want more manual map editing for tight corners and odd shapes
- ✗US stock on TerraMow's own store is spotty; Amazon and small dealers carry it
