Anti-Collision System for Robotic Lawn Mowers, WA0860

This actually works better than I expected after I read the reviews. Most of the problems listed with this "anti-collision" add-on are easily mitigated. For example, it failed to see some paving stones I had placed in a location I wanted to block off, so I just placed a second level of stones on top of the first, and problem solved. My mower is no longer banging into anything not protected by the buried wire, which has to help with the life of the mower and whatever it was banging into. Is it expensive? Yes. Is it worth it? For me yes, but you have to decide for yourself.

Loving my landroid wr155..eyes are working

The Worx robotic mower, Landroid, is supported by occasionally updated Firmware (software). Currently (as of June 2020) it is not possible to turn the ACS system on & off by smartphone app. Once installed, ACS remains 'on' constantly during unit operation. This 'on/off' option has been promised by Worx to be included in the next Firmware update. I would very much like this option as I've built a 'garage' around my Landroid's charging station and I'd like to have slit rubber mats acting as 'doors' at the entrance and exit of this station. But currently can't do this with the ACS active as it would see these mats as obstructions. I'd like to have ACS come 'on' say after a 5-sec delay when Landroid starts. That way it could leave garage passing through the slotted exit mat. When coming 'home' for a battery re-charge, I'd also like to have the ACS turned off, so it can enter charging station through the entrance mat.

I love the mower! This ACS add-on is definitely not worth the money I paid at all. It simply does not work. I have tested and have security footage of this crashing into everything all of the time. It might SOMETIMES (like 10% of the time) go around an obstacle. It runs into people, pets, trees, shrubs, totes, cars, and into SHEDS! Automotive technology it states. No way it is. I purposefully moved boundary lines and added the ACS sensor to mow around sheds and so forth. It just runs into everything! Placed cones and large (27 gallon) totes and you would expect something to work. NOPE. Completely failed 100% Stand 20 feet in front of it, and it will run into you every single time and without fail. The handful of times it HAS managed to avoid running NON STOP and directly into everything in front of it... it cuts the corner around the object like a little old lady overcompensating and hitting the obstacle width the rear wheel multiple times. After days and days of testing... I have only THREE instances of the device actually working and at least 200 complete fails. I am sick that I paid so much for something that simply does not work. ONE THIRD the cost of the entire mower, and it does nothing it is supposed to. I rave about the mower every day. I love ( we call "him" MO-E) get it (MOW) and planned to purchase the next iteration (vision) in another year (maybe two/ after warranty). Now, I am not so sure! I will have to package this back up and send it back. Then rewire the yard again, and maybe see if there is a better option on my next mower purchase.. because my faith (this ACS is a garbage device) in Worx has tanked.UPDATE: I reached out to Worx support and they claim that this is intended behavior. ?!?!?! They claim that the algorithm is the best that it can be, and that the mower turns off the ACS as it recovers from sensing the wire, and will not turn back on until seconds after it straightens itself out. Had no explanation about running into everything (runs over me and I am over 15" tall of course!). The bumper sensor is all you need, and the ACS is a complete waste of your money.

I ended up disabling mine, and wish I hadn't bought it. The only thing it seemed to avoid is, if there was a cluster of dandelions or something that grew much higher than the grass around them, the robot would avoid them when I wanted it to do the opposite. I don't have any obstacles to be avoided in my yard, though, other than a baby lilac that I put wire fencing around anyway. But even when this was enabled and I tested it by standing in the way of the mower, it still bumped into my leg.

So the lawnmower performs a little smarter with this attachment. But it still bumps into plants and will ram into things unless you put some sort of boundaries between or space the wiring multiple feet away from the desired boundary.I’ve updated this rating snd moved it down to two stars. I bought this thing because I wanted to vacation or be away from home and have the lawn mowed autonomously. However the thing (whether the accessory is on or off) drives past the boundary wire by about 12” and consistently gets itself stuck after bumping into the bushes or digging itself stuck in the dirt. After a while I started trying to send the mower home early before it gets stuck there, but when I send it home it retraces every corner of the route first l, forcing itself to get stuck. So then I started putting bricks in front of the plant as a boundary and now it just bumps into the brickOver and over until it says mower lifted
