The solo® by AL-KO Robolinho® 1121 Vision robotic lawnmower is designed for homeowners who want wire-free mowing on a larger scale, without stepping into full GPS or RTK systems. Using camera-based boundary detection, it removes the need for boundary wires or reference stations, keeping installation simple and disruption-free.
With increased battery capacity, a wider cutting width, and the option to mow in clean parallel lines, it suits medium to larger lawns up to 1100m² that are clearly defined and sensibly laid out. It’s the upper end of AL-KO’s Vision range, aimed at users who want convenience and visible results without installer complexity.
What the Robolinho® 1121 Vision Is Designed For
The Robolinho® 1121 Vision is built for homeowners who want wire-free robotic mowing on larger lawns, but whose garden layout is still orderly and predictable. It’s designed for medium to large domestic lawns where boundaries are clearly defined and the mower can rely on visual cues rather than physical wires.
This model suits users who want to avoid installation work but still expect structured mowing and reliable coverage across a bigger area.
Wire-Free Mowing at a Larger Scale
Like other Vision models, the 1121 uses a wide-angle camera to detect lawn boundaries and obstacles. The difference here is capacity. A larger battery and improved runtime allow it to maintain bigger lawns, provided the layout remains sensible.
It works best where:
- Lawn edges are clean and visually distinct
- Hard borders, paths, or edging define the grass clearly
- The lawn shape is mostly open rather than fragmented
- Obstacles are limited and predictable
If boundaries are unclear or constantly changing, coverage and efficiency will drop.
Mowing Patterns and Finish Quality
The 1121 Vision can mow in clean parallel lanes, giving a structured, striped appearance on flatter lawns with straighter runs. For more varied layouts, it can also switch to random mowing to maintain even coverage where lane mowing isn’t practical.
Cutting is mulching-only. Grass is chopped finely by the double-blade system and returned to the lawn, removing the need for disposal and supporting regular maintenance mowing.
Coverage, Slopes and Real-World Limits
AL-KO rates this model for lawns up to 1100m², but real-world coverage depends heavily on layout. Gardens with frequent obstacles, narrow sections, or slopes will reduce effective capacity.
It can handle gradients of up to 35% where traction allows, making it suitable for gently sloping lawns rather than steep banks.
Battery Performance and Day-to-Day Use
The larger 18V / 5.0Ah battery is designed for longer mowing cycles and faster recovery between charges. Operation remains quiet at around 64 dB(A), allowing the mower to work throughout the day without causing disturbance.
The battery is removable and part of AL-KO’s 1 Battery – 2 Voltages ecosystem, which adds flexibility for users with compatible cordless tools.
Smart Control and Zone Handling
Using the AL-KO inTOUCH® app, mowing schedules can be managed remotely and automatically adjusted based on weather conditions and grass growth. Two mowing zones can be set up using the supplied markers, as long as they’re connected by a straight, clearly defined path.
This works well for split lawns with simple access routes, but it’s not designed to manage multiple complex zones.
Where It Sits in the Robolinho® Range
The Robolinho® 1121 Vision sits at the top of AL-KO’s camera-based Vision range. It’s the largest model intended for wire-free operation without moving into RTK or GPS-guided systems.
If your lawn is larger, more complex, or lacks clear boundaries, stepping up to an RTK-based Robolinho® model is usually the more reliable long-term choice.
Buying from Suffolk Mowers
Wire-free robotic mowers work best when they’re matched properly to the garden. When you buy the solo® by AL-KO Robolinho® 1121 Vision from Suffolk Mowers, we help you decide whether a camera-based system is the right fit before you commit.
Pre-Sale Suitability Checks
Larger wire-free robots need the right conditions to perform well. We’ll talk through your lawn size, layout, boundaries, slopes, and access routes to make sure the 1121 Vision is suitable — or advise if a different Robolinho® model would be a better long-term solution.
Setup Guidance & Ongoing Support
The 1121 Vision is designed for straightforward installation, but if you need help refining settings, mowing modes, or zone setup, you have access to practical support from people who know the product properly.
Servicing, Updates & Warranty Support
Suffolk Mowers supports the Robolinho® range with servicing guidance, firmware support where applicable, and access to genuine parts. Annual servicing is required to maintain eligibility for the extended domestic warranty.
Warranty You Can Rely On
This model includes a 2-year domestic warranty as standard, with the option to extend to 5 years when serviced annually. Any warranty issues are handled through a specialist dealer, not a generic support channel.
