Quick analysis
Worth considering if you want a rugged Roborock mower without stepping up to the very large-lawn Z150.
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
RockMow Z120 LiDAR brings Roborock's rugged mower platform into a LiDAR-focused version: 4WD, 80% slope rating, 24 cm cutting width, 20-70 mm cutting height, six blades, 6 Ah / 129.6 Wh battery, 140 minutes of mowing per charge and app control with multi-zone, anti-theft and custom patterns. The French official page lists 2,000 m2, EUR 2,799, 21.3 kg, IPX6 and a 3-year main-unit warranty. Noise and OTA-delivered features still need confirmation.
