Which mower works with no internet or app access?

Of these four, only the Gardena Sileno City record describes operation with no internet account: it is controlled from an onboard panel or the Gardena Bluetooth app. The Mammotion LUBA mini 2 AWD 1500 and the Gardena smart Sileno free 800 both take positioning corrections over the internet, from Mammotion's NetRTK service and through Gardena's smart Gateway. The Segway Navimow H1500E's record says mowing, navigation and setup work over Bluetooth and Wi-Fi without its optional 4G plan.

Does the LUBA mini 2 AWD 1500 require a recurring RTK subscription?

The Mammotion LUBA mini 2 AWD 1500 positions by NetRTK corrections delivered over its own 4G module. Its record lists Mammotion's 4G Service as optional, free for three years and then $49.90 a year, and notes Mammotion's network RTK is free for the product's life on compatible models. The 4G plan adds remote control, live video and location tracking outside Wi-Fi range.

How does the Segway Navimow H1500E handle connectivity?

The Segway Navimow H1500E positions with GNSS/RTK and EFLS satellite-plus-vision fusion, using a GNSS receiver mounted on the property and wired back to the dock. Its record says mowing, navigation and setup work over Bluetooth and Wi-Fi. An optional 4G data plan adds remote control, updates over 4G and theft tracking, free for one year and then $32.90 a year.

How does the Sileno free 800 compare with the wired Sileno City over three years?

The Gardena Sileno City lists at $699, while the Gardena smart Sileno free 800 record carries no list price, so no three-year total is stated for it. The free 800's record prices a yearly set of six blades at $17.99. The Sileno City's record prices a blade at $3.00 and adds monthly wire checks and an annual wire audit.

What if a manufacturer's cloud infrastructure changes or shuts down?

On these records, two machines position through a maker service. The Gardena smart Sileno free 800 pulls correction data over the internet through its smart Gateway, so the vendor's service sits in the path of positioning. The Mammotion LUBA mini 2 AWD 1500 receives NetRTK corrections from Mammotion over its own 4G, and its record lists no documented fallback if corrections drop. The Gardena Sileno City uses a boundary wire and Bluetooth with no cloud account. A shutdown scenario is not addressed on any record.
