12 common mistakes when choosing a robot mower

Most disappointments with a robotic mower are not due to completely faulty technology, but to the model not matching the garden or incorrect installation. The following list includes problems that most often appear before the first full week on the job.

1. Counting the entire plot instead of the lawn

The robot handles grass surfaces, but patios, house, flower beds and driveways contribute to the complexity of the route. Measure each zone and passage separately.

2. Buying exactly at the limit of the declared square footage

Maximum area is achieved under specified conditions. Leave room for obstacles, zones, grass growth and limited operating hours.

3. Skipping slope at boundary

The robot can drive up a steep slope in the middle of a lawn, but may not be able to safely turn around a slope, wall or water. Check the inside and border limits separately.

4. Choosing RTK for a garden without a view of the sky

Large trees, tall buildings and narrow patios can weaken satellites. In such a garden, you need a hybrid system, LiDAR or vision.

5. Vision selection to unreadable limits

The camera may have a problem when the grass smoothly transitions into similar vegetation, the border is missing or the border is constantly shaded and wet.

6. Wrong station location

A station on soft ground, a sharp bend, a slope, or under a tight roof may cause docking problems. Requirements vary between models, especially in satellite systems.

7. Lack of lawn preparation

Tall grass, branches, toys, ropes, stones and deep holes lead to stops or damage. Do the first mowing traditionally and remove obstacles.

8. Altitude too low from day one

The grass may be weakened and the shield may hit the ground. Start high and lower gradually.

9. Night schedule

Night increases the risk to hedgehogs and other animals. The camera may also need good lighting. It's safer to mow during the day.

10. No hardest places test

Before accepting the installation, observe the passage through narrow corridors, slopes, wet areas and the water area. This is where the limitations come in.

11. Ignoring service and parts

The application and attractive price will not help if there are no blades, station, wheel or local repair point during the season.

12. Map update and copy missing

Updates may improve navigation and security. Save the map or settings if the manufacturer provides such a function, and monitor the robot after a major update.

Checklist before purchasing

• actual lawn square footage and inventory;
• maximum slope and slope at the boundary;
• narrowest passage and highest threshold;
• number of zones and route;
• sky view, trees and network coverage;
• local service, warranty and parts;
• safe working hours and presence of animals.

Verdict

A good purchase starts with a garden map, not with a ranking. The better you describe difficult areas before selecting, the less risk the robot will require daily rescuing.

Errors after first month

No sensor cleaning

Camera and LiDAR may gradually lose effectiveness before the user notices a clear error. A short check once a week is better than waiting for a series of arrests.

Ignoring worn blades

Blunt blades increase drag, tug at the grass and may reduce operating time. Replacement is usually simple, but must be done as a complete set and in accordance with the instructions.

Over-map correction

Any small adjustment can create overly complex boundaries. Simplify the map instead of guiding the robot around each stone. It is better to physically protect small elements or include them in one prohibited zone.

Errors when comparing offers

• Compare the promotional price of one model with the list price of another.
• Skipping the cost of antenna, garage, transmission and installation.
• Treat slope percentage as degrees.
• Compare different regional versions with the same name.
• Assumes feature announced on OTA works on date of purchase.

How to collect the installation from the seller

Request a map save, a display of prohibited zones, a return to station test, passage through the narrowest corridor and manual stop instructions. Write down the serial number, warranty conditions and how to report the failure. Don't sign for acceptance only after seeing one straight pass.

Red flag in advertising

Beware of claims like "works everywhere", "zero support" and "no signal at all". Every technology has requirements. A reliable offer describes restrictions, test conditions and elements that need to be checked on the plot.

FAQ: what to check before payment

Are online reviews enough?

No. The same model may perform great in an open lawn and poorly under trees. Reviews help find common problems, but the decision requires reference to your own garden.

Is it worth buying the first delivery model?

You can, but you have to accept a higher risk of software errors and limited parts availability. Please check the return policy and do not base your purchase on features promised in a future update.

Is the installer responsible for the map?

The scope of the service must result from the contract. Determine if it includes weekly corrections, station relocations and remapping after garden changes.
