A documented record of a failed repair, a returned mower now held by Mammotion, a replacement withheld on inventory claims inconsistent with public retail availability, and the direct financial losses that have followed.
My Mammotion Luba 2 AWD 5000 — ordered November 28, 2024 through Walmart.com, sold and shipped by Mammotion itself (Order #2000125-98958976), delivered December 4, 2024, and paid by American Express — was defective within seven months of delivery — a battery/charging fault (Ticket 225819, June 2025) followed by boundary, endurance, and auto-return failures. A warranty repair in June 2026 failed to resolve the faults; Mammotion's own correspondence acknowledges the issues recurred "shortly after the previous repair." When Mammotion then asked me to pay for parts on a second repair, I refused — and after Mammotion first attempted to substitute a refurbished unit, it agreed in writing on September 4, 2026 to ship a brand-new same-model replacement, with the exchange approved September 8, 2026.
I honored my side of that agreement: I returned the mower under RMA DR202609090099, and it was received at Mammotion's service center on September 22, 2026 (receipt confirmed by Mammotion on September 25). Mammotion has not honored its side. It now claims the Luba 2 AWD 5000 is out of stock and that its "sales warehouse and after-sales warehouse operate as two independent systems" between which "cross-warehouse transfers are not supported" — while the identical model is actively offered for sale, in stock, by Mammotion and authorized retailers across the internet. A company cannot simultaneously sell a product to new customers and tell an existing warranty customer the same product does not exist to fulfill its obligations — least of all here, where Mammotion was the seller of record on the original order. The "sales warehouse" it claims it cannot draw from is the very channel that sold me this unit. I consider that representation false and misleading, and it is documented verbatim in Section 03.
As of today, Mammotion holds both the returned mower and the full purchase price. I hold neither a mower, nor a replacement, nor a refund — while paying a lawn service roughly $150 per visit to do the job the mower was purchased to do.
Unit repaired under warranty June 2026; the same faults recurred immediately. Mammotion then sought payment for parts on a second repair.
Exchange approved Sep 8; mower returned and received Sep 25. No replacement shipped — "no available stock."
"Separate inventory" and out-of-stock assertions, while the same model is sold as in-stock to the public.
$1,865 in direct third-party mowing costs to date — every line invoiced or bank-verified — itemized in Section 04, and growing weekly.
Purchase figures per the order record: item price $2,199.00 after promotion, Ohio sales tax at 7.5% ($164.93), free shipping — the mower's $2,363.93 share of the order's $3,494.81 total, the remainder being an unrelated second item whose price is independently established by its own standalone order record ($1,130.89). Full order documentation available on request.
Ordered November 28 through Walmart.com with Mammotion as the marketplace seller of record; delivered December 4. Paid with American Express Platinum. Unit serial Luba-VSMLJGYL; Mammotion account registered December 17, 2024.
Walmart Order 2000125-98958976Within seven months of delivery, the charging fault is reported under Ticket 225819. Mammotion suspects a batch-related power-supply fault (requesting a photo of the power supply "which can show its batch") and replaces the charging-station adapter under warranty — with its first stock-shortage explanation:
"Due to insufficient stock in the Local warehouse, we have urgently arranged to ship from the China warehouse… estimated arrival 7–15 days."Ticket 225819
Invoice delivered by text message; payment documented by cleared U.S. Bank check #5438 (7/21/2025).
Check #5438 — $150.00Logs escalated under Case L2-893393885684826112; repair order created and shipping label issued June 2 ("Live Chat" thread). Unit surrendered in good faith for repair; delivered to Mammotion's service center June 13, 2026.
Case L2-893393885684826112With the mower surrendered for repair on June 2, a second company is brought in to cut. Payment documented by completed Zelle transfer.
Zelle 6/8/2026 — $165.00First cut of the season plus extreme trimming performed by the regular lawn service during the repair outage; a second cut follows the same week. The vendor's note corroborates the June 8 second-company engagement above.
Invoice #4152 — $305.00Mammotion's own email acknowledges the mower drives outside its boundary, has poor battery endurance, and will not auto-return to the charger — after the repair. Refund and newer-model replacement declined, citing the 30-day return window; 24 cutting blades offered as goodwill.
Case 906427946942595072"Since you have already had one repair performed previously, we will waive the shipping and labor costs… you will only need to pay for the cost of parts."
Rejected the following day: the unit was faulty from day one and the first repair "was not done appropriately." Third-party mowing costs documented to Mammotion; deadline given.
Case 924045370344865792Mammotion offers a replacement of the same model (warranty merely carried over, not renewed). On August 30 it admits the replacement would be refurbished; this is refused, and on September 4 Mammotion agrees in writing to ship a brand-new LUBA 2. It then hedges:
"As inventory is constantly changing, we cannot guarantee that LUBA2 will be in stock when we arrange your shipment. Please be prepared to wait."
Mow & trim plus double cut necessitated during the outage.
Invoice #4210 — $280.00Mammotion approves the exchange and issues RMA DR202609090099 with a return label on September 9, instructing return of the mower so the replacement can be arranged "after our warehouse received your mower."
Mow & trim with double cuts on Sep 9, Sep 18, and Sep 26.
Invoice #4236 — $700.00Received September 22 under RMA DR202609090099; Mammotion confirms on September 25:
"…still needs to undergo standard sorting and warehousing procedures… has not yet been officially entered into the system."
From this date forward, Mammotion is in possession of both the mower and the purchase money.
Oct 1: Mammotion says it will ship "the moment it becomes available" and offers three sets of blades (≈$55) as apology — against $1,850 in documented losses. Asked directly why the unit is "not in stock" when "there are units all over the internet for LUBA 2 AWD 5000," Mammotion responds on Oct 2 with its two-warehouse policy (quoted in full in Section 03). A legal-department contact is requested.
"We just checked the stock, it is still no available stock for LUBA 2 AWD 5000 series. We will follow up… when we have any machine in stock."
Full record compiled: 54 email messages, chat transcripts, six invoices, and photographic evidence.
Refund of purchase price, tax, and shipping due. After this date, external escalation proceeds.
Verbatim statements from Mammotion Support (support-na@mammotion.com), preserved in the email record.
"Our sales warehouse and after-sales warehouse operate as two independent systems, each serving distinct business functions… These two warehouses operate independently regarding inventory management, financial accounting, and logistics processes; cross-warehouse transfers are not supported. Consequently, it is not possible to transfer inventory from the after-sales warehouse to the sales warehouse, or vice versa."
"We just checked the stock, it is still no available stock for LUBA 2 AWD 5000 series. We will follow up on the stock and arrange the delivery when we have any machine in stock."
"As inventory is constantly changing, we cannot guarantee that LUBA2 will be in stock when we arrange your shipment. Please be prepared to wait."
"Due to insufficient stock in the Local warehouse, we have urgently arranged to ship from the China warehouse."
Third-party lawn service charges incurred solely because the Luba 2 was non-functional, in repair, or in Mammotion's possession awaiting an unshipped replacement. Vendor invoices carry Mammotion-relevant notations in the vendor's own hand: "Robot Down And Another Company Mowed" (#4152), "Robot Down" (#4210). Every paid amount is independently corroborated by a bank record — cleared U.S. Bank Bill Pay checks (#5437 $125.00 · #5438 $150.00 · #5439 $305.00 · #5440 $140.00 · #5442 $280.00) and a completed Zelle transfer ($165.00, 6/8/2026); invoice #4236 recently issued, payment pending.

These losses are ongoing. Every additional week without the mower — a mower Mammotion currently possesses — adds approximately $150 per service visit. Delay has a price, and it is being invoiced.
Note: Invoice #4152 lists its second service line as "06-25-2025"; given the invoice date of 6/29/2026 and the 2026 first-cut line above it, this is treated as a vendor typographical error for 06-25-2026.
Conservatism: this claim deliberately excludes additional consequential costs — including a $152.06 repair (October 2025) of the manual backup mower that had to be returned to service because the Luba was non-functional. The amounts claimed are limited to direct, documented lawn-service charges.
