- Our score: 8.5 out of 10
- Price: $349 (checked Nov 2, 2026)
- Status: preorder
- Best for: small edged vegetable beds
- Skip if: your beds are large, uneven or already overgrown
- HTML version: https://robotsforthat.com/robot/tertill-weeding-robot/

## Verdict

Tertill is the only consumer weeding robot you can order in the US, and it works best as a maintenance tool in small, flat, edged vegetable beds where weeds are still tiny. It does not clear established weeds, and one tester had three units fail in Florida heat and rain, so skip it for big, lumpy or mulched beds.

## Pros

- No charging, runs on its own solar panel
- Cut weeds about as well as hand hoeing in a Cornell field study
- Simple one button use
- Light at 2.5 lb and easy to move between beds

## Cons

- Sold out now; orders ship by early spring
- Needs a physical border around the bed
- Ignores tall, established weeds
- Can dig ruts and get stuck in loose or tilled soil
- Pro Tool Reviews had three units fail within months

## Questions buyers ask

### Will Tertill pull out big weeds?

No. It trims newly sprouted weeds. Testers found it bounces off tall, established weeds, so weed the bed first and let Tertill keep it clean.

### Does it need a fence or wire?

It needs a solid border about 3 to 4 in high, such as edging, bricks or timbers. It does not use a boundary wire or GPS.

### Can I buy one right now?

As of November 2026 the Tertill store lists it as sold out at $349 and takes orders for delivery by early spring.
