In development — remote-control jobsite cart

The Jobsite Runner

A remote-control jobsite cart in development. The Jobsite Runner concept adapts the beach-cart platform for tools and material, with control from a handheld transmitter.

I'm a construction PM. I built this cart to haul my family's gear across beach sand — a million people watched it drive itself on TikTok. Then I looked around my own jobsites and realized the same machine solves a bigger problem: there are tools and materials to move across the site every day.

Price and availability

Price and final specifications will be confirmed before orders open. Join the waitlist for updates; no deposit is required.

What it's not

It's not a concrete buggy. Pallet-quantity masonry and deep mud want a tracked machine — if that's your work, buy the tracked machine. The intended role is carrying tools and materials across finished ground. Site suitability and operating limits will be established through testing.

First batch goes to the waitlist, in order. No deposit, no commitment — just a head count.

One email, subject "Jobsite Cart Waitlist" — that's it. Price and specs are estimates until the first batch is finalized. Remote-control operation; this line does not include the autonomous follow-me system.
