FAQs

The Flymo UltraLife 800 is a cordless robotic lawnmower built for medium gardens of up to 800m². Powered by an 18V brushless motor with wireless charging, it mows autonomously once set up, navigating the lawn, avoiding obstacles and returning to its charging station without any manual input. Its 22cm cutting width covers ground efficiently, and the cut-to-edge design means it trims right to the lawn’s borders, reducing the need for hand trimming with a separate tool. A 3-year warranty is included, providing solid long-term confidence in the product.

The Flymo UltraLife 800 is compatible with the GARDENA Smart Hub system, which allows you to control and monitor your mower remotely from your smartphone via the GARDENA app, from anywhere in the world, not just within Bluetooth range. Through the app, you can adjust mowing schedules, monitor progress, receive alerts and manage your mower’s settings. The GARDENA Smart Gateway hub is sold separately and is required for remote connectivity. This integration makes the UltraLife 800 suitable for gardens managed by people who travel, work away from home or simply prefer to monitor their garden remotely rather than needing to be on their WiFi network.

LONA is the mapping technology built into the UltraLife 800 that systematically maps your lawn to ensure complete and efficient mowing coverage. Rather than navigating randomly like simpler robotic mowers, LONA builds an understanding of your garden’s layout and uses this to plan mowing routes that avoid unnecessary repetition and missed patches. The result is more even coverage across the whole lawn with fewer pass-by errors left at borders or corners. LONA also supports the mower’s cut-to-edge capability, helping it reach the boundaries of the lawn for a clean, finished look without hand trimming.

No grass box is needed, the UltraLife 800 uses a mulching function that returns fine grass clippings directly back into the lawn. Mulching cuts the clippings into very fine particles and deposits them between the grass blades, where they break down naturally to return nutrients to the soil, acting as a gentle, ongoing natural fertiliser. Because the robotic mower cuts little and often (maintaining the lawn at an even height rather than cutting long growth in a single pass), the clippings are always fine enough to disappear into the lawn without creating unsightly build-up. There is nothing to empty and no clippings to dispose of.

The UltraLife 800 includes 2 smart environmental sensors, LawnSense and FrostSense, that automatically modify the mowing schedule based on real-world conditions. LawnSense monitors grass growth rates and adjusts how frequently the mower operates, mowing more often during warm, wet periods when the lawn grows quickly, and easing off during dry spells when growth slows down. FrostSense detects cold temperatures and prevents the mower from operating when frost is present, protecting both the lawn (which is vulnerable to damage when frozen) and the mower itself. Together, these sensors mean the UltraLife 800 maintains your lawn appropriately throughout the year without you needing to override or reprogramme it seasonally.

Yes, the UltraLife 800 includes PassageSense, which allows it to systematically navigate and cut through passages as narrow as 60cm in width. This makes it suitable for gardens with islands, connecting sections between different lawn areas, or tight gaps between borders and fences. The LONA mapping system further supports effective coverage in complex layouts by building an efficient route around your specific garden rather than relying purely on random navigation. For gardens with a more straightforward single open-plan lawn, the UltraLife 800 will cover the area quickly and evenly. For more intricate garden shapes, PassageSense and LONA work together to ensure the whole lawn is covered.

The UltraLife 800 has a 22cm cutting width and an adjustable cutting height range of 2.5cm to 4.5cm. The cutting system uses 2 steel rotary blades designed to cut precisely to the edge of the lawn, reducing the need for a separate lawn trimmer along borders. The 18V brushless motor delivers consistent cutting power whilst maintaining quiet operation at 58dB(A), comparable to the EasiLife GO 400 and far quieter than any petrol mower. The mower weighs 2.62kg, making it manageable to lift for installation, maintenance or storage.

The UltraLife 800 receives regular firmware updates delivered over the air (OTA), meaning updates are downloaded and applied automatically via the GARDENA smart system connection, with no cables or manual intervention required. This ensures the mower continues to benefit from performance improvements, new features and any bug fixes throughout its lifetime, without the need to take it to a service centre or connect it to a computer. OTA updates are increasingly standard on premium robotic garden tech and signal a product that’s designed for long-term use rather than a static feature set.

The UltraLife 800 includes a suite of safety features designed for everyday use in family gardens. Lift and tilt sensors stop the cutting blades immediately if the mower is picked up or tilted unexpectedly, the same safety standard applied across Flymo’s robotic range. The mower operates within its boundary wire at all times, so it cannot leave the designated lawn area. Operating at 58dB(A), it’s quiet enough not to startle pets or children nearby. As with all robotic lawnmowers, it’s good practice to schedule mowing at times when the garden is not in active use by young children or animals, and to ensure any pets or children are away from the lawn when it is operating.

The right choice depends primarily on your garden size and how much smart connectivity you want. The EasiLife GO 400 covers up to 400m² and uses a Bluetooth app for scheduling and control within range, ideal for smaller gardens and those who want a straightforward, accessible robotic mower at a lower price point. The UltraLife 800 covers up to 800m², has a wider 22cm cutting deck, cut-to-edge precision blades, LONA mapping for systematic coverage, GARDENA smart system integration for remote control from anywhere, and OTA firmware updates. If your garden is larger than 400m², or you want full remote smartphone control and a more intelligent coverage system, the UltraLife 800 is the clear choice. For a compact garden where simplicity and value are the priority, the EasiLife GO 400 delivers everything you need.
