Ambrogio Next Line AI Twenty 25 RTK

Manufacturer: Ambrogio

The Ambrogio Next Line AI Twenty 25 RTK is a robotic lawn mower designed for larger residential properties, offering coverage of up to 3000 m² while recommending use on areas up to 2400 m². It connects via Wi-Fi and Bluetooth, supports a dedicated smartphone app for remote control, and integrates with both Alexa and Google Assistant for voice-based operation. A built-in display, scheduling capabilities, and auto-docking round out its day-to-day usability.

Weighing 10 kg and measuring 534 mm wide by 386 mm thick, the mower runs on a 25.9V removable battery that fully recharges in around 2 hours, drawing 130W during operation. Its cutting width is 29 cm, with adjustable cutting height between 25 mm and 60 mm across four settings, and it handles slopes of up to 35%. A working area capacity of 250 m²/h keeps larger lawns manageable, while sensors for rain, frost, and obstacles — along with weather-adaptive logic — allow it to operate autonomously in varied conditions, including light rain.

Pros
  • Covers up to 3000 m² of lawn area, making it suitable for large residential properties
  • Handles slopes of up to 35%, allowing it to navigate moderately hilly terrain without assistance
  • Includes rain, frost, and obstacle sensors that enable fully autonomous operation across varying conditions
  • The removable battery simplifies maintenance and reduces downtime when a replacement is eventually needed
  • Compatible with both Alexa and Google Assistant, allowing voice-based control without opening an app
  • Operates at just 50 dB in eco mode, keeping noise levels low during extended mowing sessions
Cons
  • At 10 kg, the unit is relatively heavy, which can make manual repositioning or transport more cumbersome
  • With only four cutting height settings between 25 mm and 60 mm, fine-tuned height adjustment is limited
  • A 2-hour charge time may interrupt mowing cycles on larger lawns that require multiple runs
  • The working area capacity of 250 m²/h means covering the full 3000 m² lawn area takes considerable time per session
Who is this for?

This robotic mower is well suited to homeowners with large residential lawns up to 3000 m², particularly those with uneven or sloped terrain, since it handles gradients of up to 35% without manual intervention. Its comprehensive sensor suite — covering rain, frost, and obstacles — combined with weather-adaptive logic makes it a strong fit for users who want a largely hands-off mowing experience throughout changing seasons. Those who are already embedded in a smart home ecosystem will also benefit from its Alexa and Google Assistant compatibility, as well as the dedicated smartphone app for remote scheduling and monitoring.

Who is this NOT for?

Users with smaller, flat lawns will find the mower's capabilities largely unnecessary for their needs, as its area coverage and slope handling go well beyond what a compact garden requires. The unit's weight of 10 kg makes it impractical for anyone who needs to frequently move or transport the mower manually between separate lawn areas. Additionally, those who prefer precise and granular control over cutting height may find the four-setting range between 25 mm and 60 mm too limited, particularly if their lawn type demands more incremental adjustments.

This robotic mower comes equipped with a broad set of autonomous features, including obstacle detection, a rain sensor, and a frost sensor, allowing it to respond appropriately to changing environmental conditions — and it can operate in rain when needed thanks to built-in weather adaptation. Scheduling is supported, so mowing cycles can be set in advance, while auto docking ensures the unit returns to its base without manual intervention. A built-in display provides on-device feedback, and the mower is compatible with both Alexa and Google Assistant for voice control integration. Anti-theft protection is included for added security, and a mulching feature lets clippings be processed directly back into the lawn during each mowing pass.

Performance:

slope performance 35%
mowing time 240 m
number of cutting height settings 4
maximum cutting height 60 mm
minimum cutting height 25 mm
working area capacity 250 m²/h

In terms of performance, this robotic mower handles slopes of up to 35%, making it suitable for lawns with moderate gradients. It delivers a working area capacity of 250 m²/h and logs a mowing time of 240 minutes per cycle. Cutting height is adjustable across four settings, ranging from a minimum of 25 mm to a maximum of 60 mm, giving users a reasonable degree of flexibility depending on grass type and desired lawn appearance.

Power:

charge time 2 hours
has a removable battery ✓
voltage 25.9V
wattage 130W

The mower runs on a 25.9V removable battery and draws 130W during operation. A full charge takes 2 hours, and the fact that the battery is removable adds a degree of convenience for maintenance or replacement without needing to service the entire unit.

Final Verdict

The Ambrogio Next Line AI Twenty 25 RTK positions itself as a capable, feature-rich robotic lawn mower built around the demands of larger properties. Its 3000 m² area coverage combined with 35% slope handling gives it a meaningful edge for homeowners dealing with expansive or uneven terrain, and the depth of its autonomous features — from frost and rain sensing to smart home integration — reduces the need for regular user input. That said, its weight and relatively limited cutting height increments mean it works best in a specific context rather than as a universal solution. For those whose lawn profile aligns with what it offers, it represents a well-rounded and technically thorough option in the robotic mower category.
