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
Four independent tests of the Roborock RockMow Z150 (T3, home&smart and Testsieger.de explicitly on this model, plus Senses.se on a unit from the RTK Z1 line whose exact size isn't confirmed but which testers describe as identical bar battery and coverage) converge on one point: the active front-wheel steering combined with the independent rear suspension makes the mower noticeably gentler on the lawn than rivals, with no scuffing on turns, a finding shared by T3, home&smart and Senses.se. Obstacle avoidance (Quad Vision, 4 cameras) is judged broadly reliable, but T3 and Senses.se find it a touch over-cautious, leaving a wider uncut margin around objects than necessary; home&smart goes further, documenting one clear miss (a run-over tennis ball) and an erratic resumption pattern after skirting an obstacle, while Testsieger.de separately notes that small, awkwardly placed objects aren't always caught in time. On edge cutting, Senses.se reports cutting to about 3 cm with the optional PreciEdge module fitted versus about 10 cm without it, a figure Roborock itself states and which T3 and home&smart both reproduce without measuring it themselves; T3, which tested without the module, confirms observing a roughly 10 cm strip of uncut grass along boundaries, and home&smart, which tested it fitted, gives no figure but observes a very close cut along edges the mower can drive over and a remaining strip along hard edges (walls, bed borders, stone kerbs). Two testers (home&smart and Testsieger.de) saw the mower get stuck on their lawns, respectively against a stone-edged seating area it failed to recognize as a single obstacle (picking up a few scratches on the housing for Testsieger.de) and repeatedly against a fence or in a dip, needing manual freeing each time. On RTK antenna setup, opinions differ: for home&smart everything worked on the first try, firmware update included; Senses.se calls the same step "actually very simple"; Testsieger.de, by contrast, had to redo it several times and restart the app before getting a stable fix, an outlier one in three. Senses.se also notes that in July 2026 Roborock announced a beta rollout of nRTK positioning that would eventually make this physical antenna unnecessary. Views on automatic mapping don't line up either, with no apparent link to test date: home&smart (May) finds it smooth on the first attempt, both in manual and automatic mode; Senses.se (June) watches it arrive mid-test; Testsieger.de (late June) still finds it flagged as beta, with repeated connection drops between the antenna and the mower; T3 (July) finds no auto-mapping option at all and has to trace the boundary by hand, while noting other reviews have since reported it arriving. On narrow passages between zones, Senses.se reports that the 0.8 m Roborock states proved insufficient in its garden, with at least 1 m needed in practice, a finding Testsieger.de doesn't confirm: it had hardly any trouble with narrow passages in its own garden. Price remains the most shared criticism, raised by T3, home&smart and Senses.se: GBP 2,999 in the UK for the Z150 T3 tested (against GBP 1,699 for the Z115, GBP 2,299 for the Z130, and up to USD 3,500 stated in the US by the same tester), a EUR 3,499 list price in Germany for the Z150 per home&smart and Testsieger.de (home&smart also giving EUR 1,999 for the Z115, and Testsieger.de separately showing, through its own price-comparison widget, a street price from EUR 2,699), and from SEK 23,499 for the RTK Z1 line per Senses.se, which doesn't publish a Z150-specific price. Each test also reports isolated points the others don't confirm: Testsieger.de measures about 60 dB at one meter, a level it itself calls quiet, but judges edge cutting disappointing even with the built-in edge mode, without it being clear whether the PreciEdge module was also fitted; it also reports a live camera feed in the app, while home&smart reports no camera access at all, including in an update to its article published after Testsieger.de's test: the contradiction between the two remains unresolved. Senses.se notes lastly that its test unit was sent by Roborock, with no editorial influence according to the outlet.
Strengths reviewers highlight
What public reviews and owner feedback most often praise.
- All-wheel drive and slope handling praised by all four testers, each describing effortless handling of rough terrain or steep slopes
- Active front-wheel steering and independent rear suspension judged noticeably gentler on the lawn, with no scuffing on turns, by T3, home&smart and Senses.se
- Obstacle avoidance (Quad Vision, 4 cameras) judged reliable but a touch over-cautious, leaving a wider uncut margin around objects than necessary, by T3 and Senses.se
- Optional PreciEdge module: Senses.se reports cutting to about 3 cm from the edge versus about 10 cm without it (a figure Roborock also states and which T3 and home&smart reproduce without measuring it themselves), with the cut never perfect on hard edges per home&smart
- Price judged very high by T3, home&smart and Senses.se
Limits found in reviews
Consolidated watchouts identified by SpecsLib to help evaluate fit for your lawn and budget.
- Two testers (home&smart, Testsieger.de) saw the mower get stuck on their lawns (a stone-edged seating area not recognized as a single obstacle; a fence or dip repeatedly, with a few scratches on the housing), needing manual intervention
- RTK antenna setup worked on the first try for home&smart and is judged "actually very simple" by Senses.se, but was laborious for Testsieger.de, which had to redo it several times and restart the app before getting a stable fix; Senses.se also notes Roborock's July 2026 announcement of a beta rollout of nRTK positioning that would eventually make this physical antenna unnecessary
- Opinions on automatic mapping don't line up, with no apparent link to test date: smooth on the first attempt for home&smart (May), seen arriving mid-test by Senses.se (June), still flagged as beta with repeated connection drops for Testsieger.de (late June), totally absent in T3's test (July), which has to trace the boundary by hand
- Edge cutting judged disappointing by Testsieger.de even with the built-in edge mode, without confirmation the PreciEdge module was also fitted for that test
- Obstacle avoidance isn't foolproof: Testsieger.de notes small, awkwardly placed objects aren't always caught in time, and home&smart documents one object actually run over (a tennis ball) despite otherwise reliable detection, plus a sometimes erratic resumption pattern after skirting an obstacle
- Passages between zones: Roborock states 0.8 m width is enough, and Senses.se found at least 1 m is needed in practice in its garden, or the mower gets stuck, a problem Testsieger.de doesn't confirm, having had hardly any trouble with narrow passages in its own garden
- PreciEdge module not included (about GBP 150 per T3, SEK 1,799 per Senses.se) and drops obstacle clearance from 8 to 5 cm once fitted, per Senses.se
- For a small, flat, simple garden, T3 and Testsieger.de both steer buyers away from the Z150: T3 recommends the Segway Navimow i208 LiDAR or Roborock's own RockMow S1 instead, while Testsieger.de suggests comparing more widely for an angular garden or if you expect a hassle-free device at this price
- No grass collection, clippings are mulched in place: a missed session between mows means raking up afterward, per T3
Each published test
Our summary of each published test, with the link to read it.
- T3Hands-on testin EnglishRead the testPraised
- Build quality that feels super premium; nothing creaks or wobbles
- Four-wheel drive handles slopes and rough terrain with ease; active front-wheel steering allows tight turns without scuffing the grass
- Cutting performance clean and consistent; the lawn looked noticeably more even after a few sessions
- Excellent app: real-time tracking, schedules, zones, no-go zones, mowing patterns; PIN lock, lift alarm, 4G tracking, Apple Find My support
- Three years of free 4G data included, allowing remote control even without Wi-Fi in the garden
- Z150 unit tested: 200 minutes per charge, 60-minute recharge, more than enough for the tester's garden in one session
Faulted- Huge and heavy (21.5 kg), takes up serious space, not recommended for a small urban garden
- For a small, simple, flat garden, better off with a Segway Navimow i208 LiDAR or Roborock's own smaller RockMow S1
- No grass collection, clippings are mulched in place: if the lawn has grown too much between sessions, raking is needed afterward
- Very expensive: GBP 2,999 for the Z150 tested (against GBP 1,699 for the Z115 and GBP 2,299 for the Z130), above the Segway Navimow i215 LiDAR (GBP 1,199) and close to premium Husqvarna territory
- PreciEdge close-edge cutting module not included, GBP 150 extra; without it, a roughly 10 cm strip of uncut grass remains along boundaries, still requiring a strimmer
- No auto-mapping option found at the time of testing despite the promised AI-powered mapping; manual boundary tracing needed via the app (the tester notes other reviews have since reported AI mapping arriving via a software update)
- Obstacle avoidance a touch over-cautious, leaving a wider uncut margin around objects than expected
- Senses.seHands-on testin EnglishRead the testPraised
- All-wheel drive handles the claimed 80% (38.7°) slopes and obstacles up to 8 cm without issue: "we have had difficulty finding anything in the garden that actually stops it"
- Active front steering and independent rear suspension: very small turning radius, no scuff marks on turns, clean cut even on lumpy ground
- Four cameras (two forward, two to the side): obstacle avoidance judged nearly perfect (slippers, toys, hoses found and neatly routed around)
- Built-in front light enables night mowing
- Optional PreciEdge module: cuts to about 3 cm from the edge versus about 10 cm without it
- RTK antenna installation judged actually very simple, with an included cable long enough that it doesn't have to sit right next to the dock
- Runs on 4G without Wi-Fi once set up, with three years of data included
- Clean, intuitive app, a wildlife-friendly night mode, robust anti-theft (PIN, alarm, 4G tracking, AirTag support)
Faulted- Software still maturing: features arrive over time (AI mapping showed up during the test period), pattern mowing wasn't promised before the third quarter
- Obstacle avoidance sometimes overly cautious, with wide detours leaving an excessive uncut margin
- PreciEdge module not standard (SEK 1,799 extra) and drops obstacle clearance from 8 to 5 cm once fitted
- Passages between zones: the 0.8 m Roborock states proved insufficient, with at least 1 m needed in practice for the mower to get through without trouble
- High price: from SEK 23,499 for the RTK Z1 line (no Z150-specific price published by this outlet), SEK 31,999 for the LiDAR version
- A physical RTK antenna was still needed at the time of testing; Roborock announced in July 2026 a beta rollout of network-based nRTK positioning that would eventually remove the need for it
- Test unit sent by Roborock; the outlet notes that suppliers have no editorial influence over its tests
- home&smartHands-on testin GermanRead the testPraised
- Cutting result rated among the best this outlet has seen in 2026: straight lanes, high tracking precision
- Active front-wheel steering noticeably gentler on the lawn than rivals; no marks or damage seen in the grass during testing
- Both manual and automatic mapping worked without a hitch on the first attempt during testing
- Reliable obstacle detection on a garden hose, small cones, tennis balls and larger objects
- App setup succeeded on the first try, including the firmware update and the RTK antenna connection
- Premium-grade build, tight fit and finish
- Clear, well-designed app
Faulted- Got stuck once against a stone-edged seating area the robot failed to recognize as a single obstacle; needed manual freeing
- When it meets an obstacle it often keeps an unusually wide distance, then sometimes resumes mowing in a completely different spot instead of returning to its original line, giving an erratic mowing pattern near obstacles; the only clear miss documented was a run-over tennis ball
- Edge cutting with the PreciEdge module clearly better than without it, but still not perfect on hard edges (walls, bed borders, stone kerbs): manual touch-up still needed
- Only three mowing modes (full, zone, edge), no manual mowing, no spot mowing, no camera access
- Longer setup than most 2026 models: PreciEdge module shipped separately (about 12 minutes to mount), 15 to 20 minutes total versus under 10 minutes for many rivals
- Very high list price: EUR 3,499 for the Z150 against EUR 1,999 for the entry-level Z115
- Testsieger.deHands-on testin GermanRead the testPraised
- Clean, even cut, no visible gaps or missed strips once the map and connection were stable
- Quiet operation: about 60 dB measured at one meter
- Effective hedgehog protection against a dummy used for testing, with a time window preventing mowing at dusk and at night
- Very complete app (live map, zones, no-go areas, schedules, remote control, electronic cutting height, speed, mowing patterns, notifications, live camera)
- Strong slope handling; Roborock states 80%, a figure the tester relays without measuring it directly, provided signal, map and critical spots all cooperate
- Full safety suite (lift and tilt sensors, stop button, PIN, alarm, collision sensor, child lock, automatic rain stop), working reliably in testing
- Easy maintenance: accessible cutting deck, simple blade change with tools and spare blades included (EUR 19.90 per replacement set)
- Hardly any trouble with narrow passages, controlled movement between zones
- Swappable battery
Faulted- Sensitive RTK antenna: several attempts and an app restart were needed to get a stable fix during setup
- Automatic mapping still flagged as beta at the time of testing, with repeated connection drops between the antenna and the mower forcing restarts
- Repeatedly got stuck against a fence or in a dip, needing manual intervention and picking up a few scratches on the housing
- Obstacle detection decent but not flawless: small or awkwardly placed objects aren't always caught in time
- Disappointing edge cutting: even with the built-in edge mode, too much grass is left standing at many edges, still requiring manual touch-up
- Insufficient winterizing guidance: little detail on end-of-season cleaning or battery storage
- Suits an open plot with few difficult edges; for an angular garden, or if you expect a hassle-free device at this price, better to compare more widely
