Quick analysis
A formidable machine for slopes and complex terrain, held back by a young app experience.
SpecsLib Calculated Metrics
These indicators are computed by SpecsLib from official manufacturer specs. They do not appear as such in any brand's documentation.
Area / Price8 sq ft/€
Square feet covered per euro spent. The higher the ratio, the better the area-to-price value.
Mowing density9,226 sq ft/hr
SpecsLib estimate (max area ÷ runtime), not published by the manufacturer: actual mowing time includes mapping, obstacle avoidance and recharging, so this figure likely overstates real-world throughput.
Slope score80/100 (Exceptional)
Normalised score based on the declared maximum slope (80%). 100 = mechanical limit, 0 = flat ground.

This model's technologies, against the evidence
What the brand promises, what independent tests actually found, and the limit to plan around.
Roborock PreciEdge
Brand Promise
An edge module brings the cut to around 3 cm from the boundary.
What testers found
Senses measured roughly 3 cm with the module against roughly 10 cm without it: the function does what it says. Two reservations. The module was sold separately, 1,799 SEK at the time of the test, and once fitted it drops obstacle clearance from 8 cm to 5 cm and reduces agility.
Watchout / Limitation
Depending on the version the module ships with the mower or is bought separately: the 3 cm figure assumes it is there. The same test found software still under construction, mowing patterns pushed back, and passages between zones needing close to a metre.
What the tests say
The RockMow Z120 LiDAR stands out as a formidable machine on difficult terrain, though its software still requires maturity. CHIP, Connect, and inside digital unanimously praise its excellent traction (AWD, active steering) which allows it to handle slopes up to 80% and complex gardens without damaging the turf. The LiDAR navigation and eSIM connectivity prove highly reliable. However, all three outlets note software weaknesses: CHIP points out the strictly manual mapping and the lack of a live video feed, while Connect and inside digital highlight an imperfect app and note that the edge cutting module is an optional extra sold separately.
