WORX Landroid Vision Cloud WR320 Robotic Lawn Mower

RTK corrections from the cloud, so nothing goes on a pole

The Landroid Vision Cloud's selling point is that the satellite correction data arrives over the internet instead of from a reference station in your garden. WORX describes it as RTK Cloud: satellite signals are compared with known reference points and corrections are delivered to each individual mower, with no hardware to install at home. WORX' feature list also says lifetime free RTK Cloud service at no extra cost, and the Amazon bullet repeats that there are no additional cloud costs.

When trees or buildings block the satellites, WORX says the mower switches to sensor fusion: V-SLAM from its stereo cameras, inertial data and wheel odometry keep the routing accurate until the satellites return. Mapping is automatic rather than driven: V-SLAM builds a 3D model of edges and features while RTK records the coordinates.

Connectivity is Bluetooth and Wi-Fi plus RadioLink, a separate link WORX includes to extend coverage across larger lawns. The manual's accessory table confirms RadioLink is supplied with WR320 and WR320.1 but not with the quarter-acre WR310 versions.

The number after the dot changes what you get

This is the most important thing to check before ordering. WORX' manual covers four versions in one technical-data table: WR310, WR310.1, WR320 and WR320.1. This listing's model number is WR320, while WORX' own half-acre product page is for WR320.1 and its marketing describes that version.

Two differences in that table matter. Cutting height adjustment method is listed as Manual for WR310 and WR320, and Electric for WR310.1 and WR320.1. So on a WR320 you set the height on the machine, not with the app slider WORX advertises. The Cut to Zero offset-blade module is marked N for WR310 and WR320 and Y for the .1 versions, and the accessories table gives one Cut to Zero module to the .1 versions only.

The manual's diagram pages add a third: Find my Landroid is labelled standard only with WR320.1. WORX' product page for the .1 advertises 24/7 anti-theft protection and locating the mower from the app even when it is off. Because the manual ties that feature to the .1, confirm with WORX whether the WR320 on this listing has it before you rely on it.

Cutting numbers from the manual's own table

For the WR320 the manual gives a cutting area of half an acre, 2,000 square metres, a cutting diameter of 8.7 inches or 22 centimetres, a three-blade cutting system and a no-load speed of 2,400 per minute. Cutting height is listed as six fixed steps: 1.57, 1.97, 2.36, 2.76, 3.15 and 3.54 inches, which is 40 to 90 millimetres. Amazon's details table says five positions, so use the manual's six.

Slope is 30 per cent, which WORX gives as 17 degrees. The table carries a footnote worth knowing even though it does not apply to this version: if the mower is fitted with the Cut to Zero module, WORX does not recommend operating it on slopes greater than 15 degrees. That is a reason the plain WR320 may suit a sloped lawn better than the .1.

The battery for the WR320 is a 20-volt 5 amp-hour PowerShare pack, model WA3675, charged by a WA3752 charger rated 120V 60Hz 90W in and 20V 3.0A out, in about 100 minutes. The manual gives machinery weight as 27.6 pounds for the WR320 and 30.9 pounds for the WR320.1; Amazon's table says 44.5 pounds, which looks like a packed weight. Waterproof level is IPX6 and the mower is a Class III appliance.

A wire-free mower that still ships with a wire

The listing says no perimeter wire, and that is true of the boundary. What the box still contains, per the manual's accessories table, is a No-Go Line of 6 metres with 10 lawn stakes and 8 lawn screws. WORX' own in-the-box list for the .1 version gives the same thing as 19.7 feet of No-Go Line with ten stakes. It is there for marking off an area you do not want the mower to enter, so plan a small amount of pegging even on a wire-free install.

The rest of the carton for a WR320 is the mower, the charging tower and base plate, the power supply, the 20V battery, a hex key, six spare blades, RadioLink and the manuals. The .1 versions get eight blades and the Cut to Zero module instead of six blades and no module.

The manual asks you to prepare the lawn and keep preparing it: inspect the area and remove stones, sticks, wires and bones before mowing, and periodically inspect and clean the boundaries between grass and non-grass, because clear boundaries are how the camera identifies the working area. That is a real chore on a vision-guided mower that does not exist on a wire-guided one.

Rain, weather scheduling and the safety rules

The WR320 has a physical rain sensor: it is labelled on the manual's mower diagram and it has its own status message, F01 rain delay, in the error table. WORX' product page for the .1 also lists a rain sensor and describes weather-adaptive automatic scheduling that factors grass species, season, sunlight, rainfall and growth rate instead of a fixed timetable.

Other messages in the manual's table are worth knowing before you buy: E01 out of working area, E02 wheel motor fault, E03 blade motor fault, E05 mower lifted, E06 mower upside down, E07 battery charge error and E08 charging station not found. E07 includes a specific instruction: below 0°C the mower stops charging and should be stored indoors.

Safety instructions include never lifting or carrying the mower with the power key on, never operating it without the guard in place, entering a PIN before it will start, setting your phone to lock after 30 seconds so the app cannot be misused, and avoiding use in bad weather, especially with a risk of lightning. For public areas WORX asks for warning signs around the working area.

Blades, cleaning and a three-year warranty with a one-year battery

Blade changes are a set job. WORX says to switch the mower off and remove the battery, wear gloves, unscrew the blades, and replace all three at once using new screws every time, because reusing screws risks the blade coming loose and unbalancing the disc. After fitting, check each blade spins freely. No replacement interval is given in the pages we read, so inspect them regularly as the safety section asks.

Cleaning is hose only. The manual states in capitals that the mower can only be washed with a hose and that a high-pressure washer must not be used, because high-pressure water gets past the seals into electronic and mechanical parts. Make sure the battery pack cover is closed before washing. For storage, keep the battery fully charged in a cool dry place, and the charging station can be fully removed if it needs repair or long storage.

The warranty statement gives three years from the date of purchase for the Landroid Vision Cloud robotic mower, excluding accessories and consumables, with WORX repairing or replacing defective parts or the unit free of charge. Battery packs are guaranteed for one year only, and only the original pack or the same model number. Coverage requires genuine WORX parts, fair wear and tear, no trade, professional or rental use, and no repair by anyone other than an authorised service centre.

The exclusions name two things buyers trip over. Accessories such as blades and wheels are not covered, and damage from any cleaning method other than hose water, including pressure washers, steam and a hose fitted with a nozzle, is excluded. The warranty applies only to the original purchaser and is not transferable, and claims need a registration document plus a receipt showing date and place of purchase.
