Greenworks C6 Robotic Lawnmower Review UK 2026

Key specifications

Mower Type and Power

This lawn mower positions the C6 as a wire-free robotic lawn mower, meaning there is no boundary wire to install. As a robotic mower, it is designed for unattended operation and follows planned routes to cover the lawn. The claimed working capacity is up to 600 m², which suits medium to larger gardens. Power details such as battery voltage, power ratings, and run time are not stated, so expectations should be based on usage needs.

Cutting Width and Deck

Cutting performance of the Greenworks is influenced by its cutting-height range of 20 - 90 mm, which is designed to handle different grass lengths as the season changes. The deck is built to support even, low-maintenance mowing by helping maintain a consistent blade path across typical lawns. In use, owners should set the cutting height to match the lawn's growth level, then allow the robot to make repeated passes until the grass looks uniformly trimmed. If the lawn is uneven, more passes may be needed.

Lawn Size and Collection

For lawns within its stated limits, the lawn mower is built to work on up to 600 m², making it suitable for many medium-sized gardens where manual mowing would be frequent. It suits irregular layouts as long as the area remains within that maximum, since the mower must complete planned coverage consistently. For lawns above 600 m², it is not stated how trimming could be managed across additional zones over time, as continuous full coverage beyond 600 m² is not stated.

Ease of Use and Storage

With coverage limits covered for lawns up to 600 m², the focus then turns to how the Greenworks fits into daily routines, including starting, managing its route, and storing it between sessions. Once set up, it is a wire-free robotic mower, so everyday use centres on launching the job and letting it work without cables. Its route planning and auto-mapping are designed to follow a planned pattern rather than moving randomly. For storage, it is compact enough to be kept between sessions indoors or in a dry shed.

Who Is This Lawn Mower For?

This robotic mower is for people who want low-effort mowing on smaller-to-mid sized lawns, up to 600 m², rather than constant manual trimming. It suits homeowners who can spare time at the start to set up auto-mapping and route planning, as initial configuration affects results. It is also a good fit for buyers in residential areas looking for a quieter mowing experience, with ultra-quiet performance stated. The adjustable cutting height of 20-90 mm helps when grass varies across seasons.
