WORX Landroid WR141E Robotic Lawnmower for Medium Gardens up to 500m2 - Automatic, WiFi-Connected Robot Lawn Mower with App Control, AIA Technology and Adjustable Cutting Heights

Well worth the effort required to set up the mower and its guide wire. Has generally worked reliably since and the lawn already looks better. Just a few teething issues, through running the wire marginally too close to edges leading to the mower getting stuck, and one incidence of the guide wire itself getting cut - it does seem to stretch a little and raise up in places. in that respect Worx could have been more generous in the provision of pegs and spare connectors. The on board display and control logic is rather confusing. The app is better and quite comprehensive but could do with better instructions. But overall well satisfied with the purchase.

I got two units of the WR155E L2000 to cover a large and complex garden. Because of the number of garden features like ponds and flower beds of varying sizes, I also added the ACS and Off-Limit modules in the hope that they would make the mower "smarter". In my experience, the core unit worked reasonably well, but my two added module made the mower dumber (more below). I have also had to order the ACS module from the Worx official site instead of from Amazon due to stock issues, and sadly the Worx site has been a customer service nightmare.The initial boundary wire setup took days, and the adjustments have since taken weeks and are still ongoing. If you have a complex garden like mine, you will need plenty of extra boundary wires to mark the long perimeter plus the perimeters of each garden feature. First thing to know is that the boundary wire works just as a long antenna, so you don't need to buy them from Worx -- any cheap unshielded wire from the local hardware store would work. In the manual it says that the length limit of the boundary wire is only 450m, but you can go theoretically go higher if you use wires with larger diameters and therefore lower resistance. In my case I used 1.5mm wires and easily went above 600m without issues.Now, the mower would struggle with tall grass and uneven grounds. A small rabbit hole would often be enough to get the mower stuck, so expect to spend time keeping the ground even for the mower to function properly. On balance, however, the mower does save one time and keep the lawn in a better shape.Now onto the modules -- while I liked the idea of a modular design, and that the module hardware seems to be well-built, the software works so poorly that I would not recommend getting either the ACS or the Off-Limit module.The ACS has two major problems:1. it assumes every obstacle is a pole, so it could avoid a tree but would drive straight into a wall.2. it avoids tall grass! This second problem means that during the period of rapid growth, sometimes the grass would grow enough between mowing sessions (remember that the mower doesn't cover the whole lawn every time, and also cannot mow in the rain, so sometimes the same patch would not be mowed for days) such that the mower would start avoiding it.Overall the mower works better without ACS.If the ACS is less than helpful, the Off-Limit module is positively damaging:1. The top problem is that it doesn't always work. Sometimes the mower wouldn't recognise the module and would behave as if the module isn't installed, and other times the mower would recognise the module and still mow through the magnetic strips, destroying whatever the Off-Limit strips are meant to protect.2. The other major problem is that even when the Off-Limit module functions, it always turns 180 degrees around when it hits a magnetic strip, instead of applying the randomised turn algorithm. That effectively leaves the area around any Off-Limit strip less mowed statistically, a problem that is further exacerbated if the strip is used near a hard-to-reach area.So as some other reviews have pointed out, it is better to either rely on the boundary antenna wires or simple wooden planks, as they are both more reliable and do not screw up the mow algorithm. Another point I want to mention is that the manual says that the magnetic strips must form a loop, but that is just nonsense for anyone who understands physics (the weaker magnetic fields at the ends don't justify the instruction either, especially when it is possible to cut a longer strip to farther remove the ends or just double up the strip). I cannot help but feel that the modules are developed to a far lower quality than the core unit.There is, however, one useful undocumented function for the Off-Limit module -- if you have an island larger than 6m x 6m, it is possible to add a short magnetic strip across the island boundary wire to break the loop, allowing the mower to not get stuck in the loop while trying to follow the boundary wire back home. It's ironic that the only valuable use of the Off-Limit model is expressly forbidden by the manual instructions.I hope that Worx would provide a firmware update that makes the modules more useful. A simple change to reuse the good random turn algorithm for both when the ACS detects an obstacle and when running into a Off-Limit magnetic strip would be enough to make the modules more useful than they are today. Until then, I would recommend the core unit but not the additional modules.

The media could not be loaded. Pro's.Quiet, easy to program either manually or via the App. Boundary wire is easy to install and once in situ lasts for years. (have had others in the range for many years)Adjustable cutting height very useful so you can alter depending on the time of year and how the grass is growing.Cut to Edge feature means this mower can cut closer to the edge than other equivelant models on the market.Rain Delay feature so you can choose if you want it to cut in wet weatherVariable or automatic programmingAll cuttings mulch down so no grass to collect - big bonus!Excellent UK support for any queries or problems - cannot find better service with any other productInterchangeable battery can be used with other Worx products.Price is good but if you look around you can often get a real bargain and as long as incomes from an official Worx supplier you will still get full UK support.Worx products rate amongst the best on the market. This model copes easily with all types of garden. Whether you decide to use it manually or program from the App it is incredibly easy to use.Cons:Power source needed to connect to charging plate.Depending on the terrain it can occasionally get stuck in wet ground. Easily resolved by inexpensive purchase of metal wheel "spike" accessory which can be easily screwed on.

I bought this several years ago, along with a smaller one to help deal with our lawn that has several different areas to it.I was so excited and we were really fascinated to watch it move around the lawn. I even bought the extra sensor to add to it so that it wouldn't run over anything it shouldn't.The issue is, although it says the area it will cut, honestly it won't manage it. The area is much smaller than advertised. Does a reasonable job on a much smaller lawn but it was difficult to set up, difficult to maintain the wire around the outside and it has been a disappointing buy in all honesty.I spent a lot of money on this and would have better invested this in a ride on.
