Yard Force Compact 300RBS Robotic Lawnmower (Orange, 300m² with Bluetooth App)

What size garden is this mower suitable for?

The mower is rated for gardens up to 300m². This is roughly the size of a typical city or suburban back garden. It is not designed for larger plots if your lawn exceeds 300m² you would need to look at the 400m² WiFi model in the Yard Force range. For gardens well under 300m² it will complete its work comfortably within its 60-minute battery runtime before returning to charge automatically.

Does it need a boundary wire installed?

Yes. A perimeter boundary wire must be laid around the edges of your lawn before the mower can operate. This wire tells the mower where the boundaries of the mowing area are. The box includes boundary wire, pegs and connectors so you have everything needed to complete the installation. Most users report the installation takes around an hour. One common tip from buyers is to place the wire closer to the lawn edge than the recommended 30cm otherwise a strip of longer grass can be left uncut around the perimeter.

How does the iRadar obstacle detection actually work?

The iRadar system uses Active Safety Ultrasonic Sensor technology. It sends out ultrasonic pulses and measures how quickly they bounce back off nearby objects. This is the same principle used in parking sensors on cars and in industrial automated vehicles. When an object is detected the mower changes direction before making contact. It does not rely solely on physical bumpers like older or cheaper robotic mowers. This makes it more effective at avoiding fragile items like plant pots or children's toys.

Can it handle slopes and uneven ground?

The mower can handle inclines of up to 30%. To put that in context a 30% gradient is quite steep roughly equivalent to a 1-in-3 slope. However several customer reviews note that even mild gradients combined with soft or mossy ground can cause the mower to get stuck. If your lawn has soft patches or very uneven terrain this is worth factoring into your decision. The mower also has tilt and turnover sensors that cut power to the blades if the machine tips or is lifted unexpectedly.

How long does the battery last and how long does it take to charge?

The Samsung 20V 2Ah lithium-ion battery provides a runtime of 60 minutes per charge. The mower returns to its charging station automatically when the battery runs low. Charging time is not specified in the product data but for a 2Ah battery at typical robotic mower charge rates you would expect a charge cycle of around 60 to 90 minutes. The charging station is included in the box and needs to be connected to an outdoor power supply.

Is the app easy to use and what can it control?

The app connects via Bluetooth and is available exclusively through Yard Force. It allows you to set mowing schedules, adjust settings and control the mower remotely. Some buyers have reported that the app can crash when setting up schedules. If the app proves unreliable the mower can also be operated manually using the onboard A2 control panel which is water-resistant. The Bluetooth connection means you need to be within reasonable range of the mower for the app to function it does not use WiFi so remote control from outside your home is not possible on this model.

What warranty does it come with and what happens if it develops a fault?

Yard Force offers a 2+1 year manufacturer's warranty on this product. The base 2-year warranty is standard and the additional year is available through registration. Customer reviews highlight mixed experiences with warranty claims some report successful repairs or replacements while others note slow response times from Yard Force support. Amazon's own returns policy offers free returns in new and unused condition with a full refund. If a fault develops after use the manufacturer warranty route would apply. It is worth registering the product promptly after purchase to activate the full 3-year cover.

Does it cut right to the edge of the lawn?

No. Because the boundary wire needs to be set back from the lawn edge and the mower follows that wire there will always be a strip of grass left uncut around the perimeter. The manufacturer recommends placing the wire 30cm from the edge but several buyers suggest halving that distance to reduce the uncut strip. The mower also does not have an offset cutting disc so it cannot cut flush to walls or raised beds. You would need to trim these edges manually with a separate tool. This is a common limitation of boundary-wire robotic mowers at this price point.
