Prices from the seller's UK website on 17 October 2026. Where we can read the seller's page automatically, today's price is shown too. Prices change often; check the seller before buying.
Without Wi-Fi, subscriptions and 4G
RTK uses your own signal stick, not the internet, so it can mow without Wi-Fi via the on-mower buttons; app features need Wi-Fi.
App over Wi-Fi.
Data note: ECOVACS UK lists the slope as "50% (24°)"; 24° is about 45%, which matches the Amazon listing, so we use 45%.
