Chinese materials fs

It's almost like YOU CAN CLEAN THE CONTACTS, do you also never sharpen your mower blades, never fill up the gas tank, empty the bag, like god damn

@@kodyritt1681 ask yourself who chooses to use those materials and why. Furthermore there are Chinese factories that make quality products but western producers only want to get cheap and low quality stuff from china as we can already make quality products by ourselves. The engineer designs the component but the materials and modes of production are mostly the results of the company owner's choices

@@CoreStarter the rate at which you have to do it is wayyyyy faster than it should have been

Ambrogio uses very good motors.

In this video the robot is mowing tall grass unexpectedly. Normally there is a final mow with a traditional mower and then the lawn stays mowed. I can't tell you how many times I posted a video of how the lawn usually looks (completely mowed always) and then people comment, "It's not mowing any grass!". Now I post one where it's mowing grass and I get the opposite comment. Bottom line: these robots work. Take the time to understand them and jump on board. Wandering aimlessly? It's a proven method. Straight lines are coming but many properties won't be suitable for those new gps-driven models due to not having a clear view of the sky. The aimlessly-driving models that work perfectly fine will be in the mix for many more years.

That video is a short reel. Visit our channel and watch this one for more details: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-9wqtH9UBkV8.htmlsi=lxu7HnUciuAL-d1o

Twenty ZR can be used in the automatic mode or the manual mode. Both L60 and Twenty ZR are perimeter wire-free, except Twenty ZR has an optional guide wire so it can find the base automatically. Twenty ZR's blade can be set a little higher, L60's max height is 2"/5cm. L60 uses humidity sensors to detect grass. Twenty ZR uses radar. The radar has an advantage because it is touchless. It can detect objects perpendicular to the ground that are at least 4" tall. Both come with the star blade that is good on leaves. L60 is better on slopes due to being 4WD. Both of these robots - it is very important to mow the grass down very low if it is extra dense before using the robot. Dense, tall grass can lift the robot up so that the wheels do not touch the ground. The robot won't have traction and can't move in that condition. Once the grass is mowed low, run the robot often enough so that this traction issue is not a problem. With Twenty ZR on extra dense grass it is sometimes necessary to lower the blade to keep the grass from lifting the robot up. There is no issue on typical grass. Do not use these robots on St Augustine grass, they won't work.

@@paradisebots Thank you. I am in Hawaii. I have El Toro Zoysia grass. Our lots here in Hawaii are smaller about 7000 square ft with the house. We have fairly simple rectangle yards. No tree debris. I do have a ground mounted solar array that I weed and mow under. That’s the only obstacle in the yard. Back yard is fence in and front yard are separated by concrete driveways and side walks. I would need to carry a robot to the front yard because I have gravel walk ways and fence separating the front from back. I am debating perimeter vs no perimeter. I currently use a yard man who cuts with a weed eater. I pay $60 a cut and cut twice a month. Durability and ability to self service are important to me especially since I am in Hawaii. I am watching all the videos I can and reading some of your post on Redit. 😎

Not 100% sure on that one. The manual indicates no, but recent software release notes indicate yes. Maybe only in the Twenty 25/29 Elite(?). Update the software, try it and let us know!

Hi, the 4.0 High Cut robot was made by Zucchetti especially for the USA. The rear wheels and front wheels are different, plus the front wheels are steered by the software. 4.0 High Cut was designed for difficult St Augustine/Floratam/Zoysia and Centipede grass types. St Augustine and Floratam are the main grass used throughout the state of Florida. It has very stiff grass blades that are about 1cm/1/4" thick. 4.0 High Cut robots do not mow low. They mow 7cm-9cm/2.8"-3.7".

@@paradisebots Oh i see :o looks nice on the 4.0 though specially the front wheels

I'm still interested in testing and reviewing one of these. I'm curious how it would work with heavy use.

@@GenetrySolar Hi, I would like to understand your concerns. Most of our robots are running daily for many hours. We support many customers with 10-15 year old robots. One customer has 7 acres and 400 trees. You can call (847)960-8520 to discuss further.

Hi and thank you! After I made the video the factory came out with torque specifications. "Girl Tight" is 1.8nm for the 4.0/4.36 battery & 1nm for lid screws, 3nm for the blade and blade motor mounting screws except on the 4.0 they want 3.5nm for the blade. They want a stronger torque on the wheel motor mounting screws and wheel bolt - 6nm, but only 2nm on the center shaft screw. Robots with the clam chassis, they want 3nm for the chassis screws. Small robots, like L20, other than the blade, the strongest torque is 2nm for the wheel shaft screw. The rest are 1.0-1.2. They also specified Blue Loctite, however, we have had issues with it being too strong. We have used Green for many years and no problems. If you choose Blue, use a very small drop. Never use Red. Btw, there is another version of this video where the only difference is I talk about cleaning the contacts.

@@paradisebots thank you so much, I really appreciate this

Hi Daniel, YES. I tested it with the Twenty Elite. I cannot say for sure regarding the Twenty Deluxe, but **maybe**. Likely yes, too, because the factory customer service told me all robots support the corridor software feature, however, it may depend on the model year and/or software version. That is, they may have spoken from their perspective of the date in which I asked the question vs reality.

How do you turn off slow border? L250i?

@@hired85 That you do in the Service menu of the robot. But consult your local ambrogio dealer before you do that because there are plenty of settings inside that menu that if turned off will impact the robot.

Hi, many Ambrogio robot models use GPS to mow more efficiently; they require a perimeter wire. There are two models that don't use a perimeter wire and one that has no perimeter wire but has a guide wire so it can find the base. Two are for very small lawns, the other is for open fields and air strips. The sites might be wrong, or maybe they are using tricky, confusing language. Generally, robot mowers should be thought of more like a sprinkler system. Sprinkler systems keep lawns watered. Robot mowers keep lawns mowed. Sprinkler systems have wires... The obsession the public has with wireless robot mower systems is confusing. Major manufacturers have been pursuing it for six decades. I'm not holding my breath.

Those sites are wrong. If people are using AI to write articles, there will be all kinds of misinformation. All Twenty models require a perimeter wire. There are no guide wires so it is much simpler to install than brands that require guides, too. If it's an Elite model, it uses GPS to assist in mowing more efficiently. The dealer can set GPS Fast Return in the service menu after one week.

There are new Ambrogio models that use GPS + RTK and do not require a perimeter wire. They can only be used on open areas, though. The wire is optional for those models.

A gate is a special wire shape that traps the robot in an area. This can be advantageous if you want the robot to finish the area in one or two cycles or if the movements of the robot cause it to escape the area due to its shape or obstacles.

A gate is wire that is added to the installation to trap the robot. The wire will be placed a precise distance from itself so that the grass is trimmed between the two wires. A gate can be installed starting from the perimeter, close to the other perimeter and then back to the perimeter. Details are in this installation guide on Amazon: a.co/d/bK6VMm4

Hi, Sorry for the delay in my reply and thank you for the complements! 4.36 is definitely a good choice and it includes the 6 year warranty. Quad does not show the warranty as being available, which I have to assume is intended. We sold some Quads and they have been working great so far. They do not have the extended warranty option, though.

Hi Roger, thank you for your important question. The solution is to install an "antenna", a special shape in the wire, that recalls the robot to the wire on each side of the gate (i.e. 2 antennas). The robot will drive on top of the wire through the gate. The wire can be centered in the gate opening **if** special programming is used to ensure the robot only travels on the same wire through the gate. That is, anti/counter-clockwise or clockwise. Using this technique, the very small Ambrogio robots (L15 and Twenty) can fit through an opening as small as 16"/40cm. Most models need 28"/70cm, though (4.0, L250i, L350i, more...). Yet all of these robots will vary the distance from the wire in all other locations in the yard. The distance the robot stays on the wire is programmable by your dealer in the service menu. The default is something like 30ft/10m.

@@paradisebots ​​⁠ Aloha. What mower would you recommend for cutting El Toro Zoysia grass on a 6900 Sq foot lot? I have a gravel walkway and fence separating the front yard from back yard. I would have to carry the robot between the two. Mahalo!

To be fair, GPS isnt accurate enough for a mower. Nor reliable enough near buildings or under trees. A better comparison is a robot vacuum or self driving cars. But such clever mowers exist, google toadi.

Like the remote controls for tv’s that people used in the 1970’s that had a cord attached!

I understand your confusion. The reason is 1) a requirement of a few centimeters of accuracy and 2) a requirement to always see the GPS signal so the robot knows where it is at all times (it is a device with a dangerous and fast spinning blade, after all). GPS accuracy is more like 5mt/17feet. If the robot was off by 17 feet, it would be mowing the neighbor's yard. In the air, your drone does not have this constraint. GPS is "line of site" technology. A straight line must be drawn to the satellite without any buildings between the robot and the satellite. Generally it has to be as low as 20 degrees from the horizon to ensure the location can be triangulated. This is generally impossible to achieve since the signal will be blocked when the robot is mowing near homes and buildings. A supplemental signal will be required such as a tall beacon or multiple beacons around the perimeter. These are unsightly and will have less market acceptance than the invisible perimeter wire. Probe carefully about these issues when researching wire-free robots. Your drone can stay far enough away from buildings to maintain communication with the satellites, I assume. In cities, it probably uses WiFi to detect skyscrapers. That's how car GPS systems do it. WiFi is not dense enough in the suburbs to provide adequate coverage. It is not an acceptable alternative. Some day this problem will be cracked. We've been saying "some day" for 15 years already. ;-)

@@paradisebots Pretty sure this was solved quite a while ago with RTK. RTK can make GPS accurate to within a centimeter. I'd rather have an RTK GPS-controlled robot mower and set up the perimeters from driving it around manually than have to pay a person or personally put the wire into the ground. Especially when a good portion of said wire would have a potential chance of being damaged from possible road/utility changes.

@@jmnero4447 If you research it further you will learn that rtk solutions require a tall pole on a building because the gps signal is blocked by buildings. Also there is no rtk solution shipping now for homes due to technical difficulties. It's interesting that people are concerned about the wire for mowing yet will often have an irrigation system that also has wires. The major companies who have been shipping robot mowers with perimeter wires for over twenty years do not yet offer an rtk solution for homes. These industry-founding companies have been shipping rtk for open fields for a very long time already. They have the technology yet they do no offer it for homes. Between the tall pole and other technical issues, rtk is still not ready for prime time.

Yes, only one robot. Ambrogio 350i Elite for 1.75 acres.
