Flymo UltraLife 800 Robotic Lawnmower – 800m² | 970620701

The Flymo UltraLife 800 Robotic Lawnmower 970620701 is a dependable automated mower designed to maintain lawns of up to 800m². Its intelligent mowing system combines a wide primary cutting disc with a secondary edge-cutting disc, helping it cover the main lawn efficiently while cutting closer to borders than a conventional single-disc robot mower.

Using a proven boundary-wire installation, the UltraLife 800 can reliably navigate lawns with trees, buildings, shaded areas and narrow passages where satellite-dependent robotic mowers may struggle. LawnSense, FrostSense, app control and automatic charging allow it to maintain the lawn with minimal day-to-day involvement, while its quiet 58dB operation means it can work without becoming a nuisance.

• Suitable for lawns up to 800m² – designed for medium and larger domestic gardens.
• Dual cutting-disc system – combines efficient mowing with an improved close-edge finish.
• LawnSense and FrostSense – adapts mowing to grass growth and pauses operation below 5°C.
• Quiet 58dB operation – discreet enough for regular scheduled mowing around the home.
• Complete installation kit included – supplied with 150m of boundary wire and 200 fixing stakes.

Intelligent robotic mowing for lawns up to 800m²

The Flymo UltraLife 800 is intended to mow little and often rather than waiting for the grass to become long. It trims a small amount from the grass during each visit and finely disperses the clippings back into the lawn. These micro-clippings break down naturally, returning nutrients to the soil while removing the need to collect or empty a grass box.

Regular mowing also helps maintain a more even lawn height and avoids the sudden stress caused by removing large amounts of grass with a conventional mower. Once the installation and schedule have been configured, the UltraLife leaves its charging station automatically, maintains the lawn and returns to recharge when required.

Two cutting discs for a cleaner edge

Unlike many compact robotic lawnmowers that rely on one centrally positioned cutting disc, the UltraLife 800 uses two cutting discs with three pivoting razor blades on each disc. The primary disc provides a generous 22cm cutting width across the main lawn, while the smaller rear disc activates near the lawn boundary.

This allows the mower to reach closer to suitable lawn edges and reduces the amount of follow-up trimming normally required. The exact finish will still depend on the construction of the border: level paving and flush edges provide the closest result, while walls, raised kerbs and fencing may leave a narrow strip for occasional trimming.

LawnSense adapts to grass growth

Grass does not grow at the same rate throughout the year. Flymo’s LawnSense technology monitors mowing conditions and adjusts the schedule accordingly. When growth is slower and another mowing cycle is unnecessary, the UltraLife can skip that cycle rather than repeatedly travelling over the lawn.

This helps reduce unnecessary mowing, charging and lawn traffic while still maintaining a consistent finish during periods of faster growth.

FrostSense protects the lawn in cold weather

Mowing frozen or frost-stressed grass can cause lasting damage. FrostSense detects when the temperature falls below approximately 5°C and delays mowing until conditions are more suitable. This is particularly useful during colder spring and autumn mornings in Ireland and Northern Ireland.

Reliable boundary-wire navigation

The UltraLife 800 uses a physical perimeter wire to define the mowing area. Although installation takes longer than setting up some wireless machines, a correctly installed boundary system provides a stable and repeatable mowing area without depending on a clear view of satellites, mobile coverage or cloud-based positioning.

This makes it especially suitable for established gardens containing mature trees, high hedges, buildings, sheltered corners or narrow sections. The supplied kit includes 150 metres of loop wire and 200 fixing stakes, allowing the wire to be pegged to the surface where it will gradually disappear into the grass. It may also be buried where appropriate.

PassageSense for narrow areas

PassageSense helps the mower navigate connecting sections and passages as narrow as approximately 60cm. This makes the UltraLife 800 suitable for more than a simple open rectangle, provided the lawn areas are physically connected and the boundary and guide wires are installed correctly.

A guide wire can be used to help the mower travel reliably between sections and find its charging station, particularly where the garden contains a long or narrow passage.

Flexible charging-station placement

The charging station does not have to dominate the centre of the garden. Flymo’s flexible positioning system provides greater freedom when selecting its location and can accommodate suitable corner installations. The station should still be placed on firm, level ground with access to power and adequate space for the mower to approach and dock.

Flymo app and optional remote smart control

Bluetooth connectivity allows the UltraLife 800 to be configured and controlled through the Flymo EasiLife app when you are within approximately 10 metres of the mower. From the app, you can adjust its schedule, start or stop mowing and access compatible settings without using a display on the machine.

For control when away from home, the mower is compatible with the GARDENA smart system Gateway and app. This can provide internet-based access, additional smart-garden integration and GARDENA LONA™ mapping features. The GARDENA Gateway should be treated as an optional accessory unless it is specifically included within the selected retail bundle.

Automatic wireless software updates

Firmware-over-the-air functionality allows compatible software updates and refinements to be installed without connecting the mower to a computer. Keeping the firmware updated can provide ongoing performance improvements and access to the latest available operating features.

Quiet enough for frequent mowing

With a stated perceived sound level of only 58dB(A), the Flymo UltraLife 800 operates far more discreetly than a typical petrol or electric lawnmower. Its low noise level is particularly valuable because robotic mowers work most effectively when allowed to mow regularly rather than completing the entire lawn in one loud weekly session.

Weather-resistant and easy to clean

The UltraLife 800 carries an IPX5 protection rating and can be cleaned using a garden hose. Regularly removing compacted grass from the wheels, chassis and cutting discs helps preserve traction, cutting performance and reliable docking.

The pivoting razor blades should also be inspected regularly and replaced as a complete balanced set when they become worn or damaged.

Automatic safety protection

Integrated collision, lift and tilt sensors monitor the mower while it operates. If the UltraLife is lifted, tilted or encounters an obstacle, its cutting system stops rapidly to reduce the risk of injury or damage.

PIN-code protection prevents unauthorised operation. The UltraLife 800 does not include a built-in theft alarm or GPS tracker, so buyers requiring live location tracking should consider suitable additional security arrangements.

Frequently asked questions

Does the Flymo UltraLife 800 need a boundary wire?
Yes. The UltraLife 800 uses a physical boundary wire to define the mowing area. A 150m roll of wire and 200 fixing stakes are supplied with the mower.

What size lawn can the Flymo UltraLife 800 mow?
It is rated for lawns up to 800m². Garden complexity, narrow passages, grass growth and operating hours can affect the practical area it can maintain comfortably.

Is the Flymo UltraLife 800 a wireless or GPS robot mower?
It is a wired robotic lawnmower rather than a satellite-guided wire-free model. Optional GARDENA smart connectivity adds remote control and mapping features, but the physical boundary wire continues to define the mowing area.

How close does the UltraLife 800 cut to the lawn edge?
Its secondary cutting disc activates near the perimeter to provide a closer edge cut than many conventional centre-disc robot mowers. The final result depends on whether the lawn ends against level paving, a raised kerb, a wall or another solid obstruction.

Does the Flymo UltraLife 800 collect grass?
No. It finely mulches the grass clippings and distributes them back across the lawn, where they naturally decompose.

Can the Flymo UltraLife 800 work in narrow passages?
Yes. PassageSense allows it to navigate suitable passages approximately 60cm wide when the boundary and guide wires have been installed correctly.

Can I control the UltraLife 800 using my phone?
Yes. Bluetooth control is available through the Flymo EasiLife app when you are close to the mower. Control from outside Bluetooth range requires a compatible GARDENA smart system Gateway and internet connection.

Is the GARDENA smart Gateway included?
It should not be assumed to be included unless the product bundle specifically states this. The mower is compatible with the GARDENA smart system, but the Gateway may need to be purchased separately.

Can the Flymo UltraLife 800 be washed with a hose?
Yes. The mower has an IPX5 protection rating and Flymo describes it as hose-washable. The power supply and electrical connections should not be sprayed or submerged.

How loud is the Flymo UltraLife 800?
Its stated perceived sound level is 58dB(A), making it considerably quieter than most conventional petrol or mains-powered lawnmowers.

What warranty does the Flymo UltraLife 800 have?
Flymo provides a standard two-year manufacturer warranty on its robotic lawnmowers. This can be extended to three years by registering the mower with Flymo within three months of purchase, subject to the manufacturer’s terms.
