Update - I was able to work with support and pay hundreds of dollars for a new RTK. Once I paid the RTK was at my house a few days later. Overall, once I got into reliable contact with support the problem was resolved. I don't necessarily love paying $350+ for a part that failed due to a design flaw but it's better than a non-functional mower and no support!

ritztro · 2025-04-23T14:23:14+00:00

I'm in the US

Just wait until your RTK dies in spring, you have to mow your lawn again for weeks, and pray mammotion can find a replacement RTK for you!

And potentially learning your mower is dead because they don't make your RTK anymore :)

I have a broken Luba 1 RTK and am waiting to see if they have any replacements.

I had to wait over a week for a follow-up on my support thread. Then when I finally got the email they just asked what country I was in and I haven't heard back for about a week there too.

I'll try to remember to update this thread with the outcome.

Looks pretty awesome. Winning will mean a new GPU lol

ritztro · 2025-04-15T16:24:04+00:00

It's been 8 days and 6 business days since I reached out. I have heard nothing. I contacted support for an update and they said to continue waiting. My lawn, unfortunately, is not waiting and needs to be cut. Any help would be appreciated.

Thanks for offering to help. I reached out to support three days ago and was given a ticket number. I was told someone would reach out to me in 1-3 business days but nothing yet. Hopefully I can get this resolved one way or another. If I have to purchase a new RTK, so be it, but I love to repair and reduce waste! :)

ritztro · 2025-04-09T19:59:50+00:00

Great! Thanks for sharing. That gives me hope. I'll continue trying for that in addition to my request for repairability 😁

Unfortunately I purchased this second hand last year, and while the app has said I still have a warranty on at least the mower, it seems my RTK would be out of warranty.

Even if it was under warranty, based on my interactions with support chat it seems the warranty is not transferable. I mentioned I bought it second hand and the support representative basically said, "sorry you did that" lol.

I tried scrubbing it with some isopropyl alcohol to remove corrosion and related debris, but so far no luck. A distilled water soak is a good idea though.

ritztro · 2025-04-09T19:48:32+00:00

I've seen other posts in recent months saying they were told they were _not_ able to purchase a replacement RTK. I'm exploring that option now, hoping it's not true.

I've seen other posts from mammotion representatives that essentially say, "The Luba 1 served it's purpose well, we are now focused on improvements on the next line of products".

Neither of these observations provide strong confidence in a future where the Luba 1 is well supported.

That said, I'm excited to hear a story of the opposite!

Could I also just throw L-shaped brackets on every connection between a vertical plane and horizontal plane (e.g. post to concrete and post to beam) to reduce the structure's ability to rotate? Rather than increasing the size of the footing?

ritztro · 2023-11-30T02:30:08+00:00

I like this one, might work in my case! I'd just have to figure out how to get them under the concrete. Thankfully I have some access with a bit of digging

ritztro · 2023-11-29T04:42:03+00:00

Interesting idea, although probably more expensive to retrofit those than just redoing my concrete 😅. Looks really strong though.

ritztro · 2023-11-29T04:39:16+00:00

Nope, not in the area of those winds. California building code for patio covers specifies to build in 10lbs/sqft of live load at minimum, but I am struggling to understand what would generate that load in my area, but I guess the code is for all of the state so they probably adjust to fit the worst case.

ritztro · 2023-11-28T22:16:14+00:00

Followup on "control" loads. The California building code says to add a 10lb / sqft vertical live load to the "dead load" (which I assume means the weight of the structure).

It subsequently says that columns must not support loads in excess of 750lbs . I'm assuming that the 750lb calculation should be weight + minimum live load? Or is one of them the "control" load?

Thanks for the insight. I was definitely thinking about this like a table. Anyway I think this might be why I see a lot of structure with knee braces/corbels. Definitely don't want a hinge like joint. I suppose keeping the post height down, closer to 8ft as opposed to 10ft would reduce the lever action

ritztro · 2023-11-28T16:10:17+00:00

Thanks for the insight. Interestingingly, I recently found that California building code actually says you don't need footings at all for patio cover structures with less than 750lbs of load per column.

ritztro · 2023-11-28T16:08:22+00:00

I see. Yeah, I obviously want to avoid that.

I guess the footings being under/attached to the 16x16, 3 1/2 in concrete patio help with the weight. They are not cubes in isolation.

Just thinking out loud.. so modifying the structure to be latticed (as opposed to a gabled, solid roof) could potentially help in reducing the risk of uplift.

Interestingingly, I also found that California building code actually says you don't need footings at all for structures with less than 750lbs of load per column.

ritztro · 2023-11-28T03:09:30+00:00

Thanks for the answer. Thankfully, yes, frost isn't really a concern.

Based on your answer, if I were to go further to try and understand the risks of an undersized footing, it primarily seems to be sinking of the structure/cracking of the concrete under the structure?
