What to check before buying a professional robot mower
Area capacity is the most important spec for professionals. A mower rated for 1 acre will typically need to run daily to keep up with growth. Slope rating is critical for hillside properties; models with 45% or higher are needed for steep banks. Battery ecosystem matters if you already own tools from a brand like Makita or Bosch. GPS and boundary wire systems affect installation time; EPOS models save hours of wire laying. Build quality and warranty length indicate commercial durability. Owner reviews often mention reliability and ease of service.
Mistakes to avoid when choosing a robot mower
Do not underestimate slope requirements. A mower rated for 35% will struggle on a 40% hill, leading to frequent stuck alerts. Avoid buying a mower with insufficient area capacity; running a unit at maximum capacity every day reduces battery lifespan. Do not ignore the need for a clear GPS signal if choosing a wire-free model. Overhanging trees can block satellite reception. Finally, do not skip the boundary wire installation guide; improper layout causes navigation errors and missed spots.
FAQs
Can a robot mower replace a professional landscaper?
No, robot mowers handle routine mowing but cannot edge, trim, or manage complex landscaping tasks. They are best used as a labor-saving tool for regular cuts.
How long does a robot mower battery last?
Most professional models run for 60 to 120 minutes per charge, with recharge times between 60 and 90 minutes. Larger batteries provide longer runtime.
Do robot mowers work on slopes?
Yes, but slope ratings vary. Models like the Stihl iMow 632.0 handle up to 55%, while others are limited to 30-45%. Always check the spec for your terrain.
What is the difference between GPS and boundary wire systems?
GPS systems like Husqvarna EPOS use satellites to define the mowing area without wires. Boundary wire systems require a physical loop installed around the lawn perimeter.
How often should a robot mower run?
For professional results, run the mower daily or every other day during the growing season. Most models can be scheduled via app to mow multiple times per day.
Are robot mowers weatherproof?
Yes, most professional models are rated IPX5 or higher, meaning they can withstand rain. However, they typically return to the charging station when rain is detected.
Can I use a robot mower on multiple properties?
Yes, but you will need to move the charging station and boundary wire or GPS setup. Portable models like the Makita LMR400 are easier to transport between sites.
What is the warranty on professional robot mowers?
Warranties range from 2 to 5 years depending on the brand. Husqvarna and Stihl offer the longest warranties for commercial use, typically 3-5 years.
Do robot mowers require maintenance?
Yes, regular cleaning of the blades and chassis, blade replacement every 1-2 months, and battery care are needed. Professional use may require more frequent maintenance.
Can a robot mower handle wet grass?
Most models can handle damp grass but may struggle with very wet or long grass. It is best to mow when the grass is dry for optimal cut quality and battery life.
What is the cutting height range for professional models?
Cutting heights typically range from 1.0 to 3.5 inches, adjustable in small increments. Professional models offer more precise adjustment for different grass types.
How do I secure a robot mower from theft?
Most models include a PIN code lock and theft alarm. GPS tracking is available on premium models like the Husqvarna 450X EPOS, which can locate the mower if stolen.
