iRobot Roomba 780 with accessories, charging error, sold as junk

Thank you for looking.

This is a listing for an iRobot Roomba 780.
Purchased around 2013.

It has been stored for a long time, barely used for the past few years, but it was working when used occasionally.

However, when I tried to charge it about a month ago, an error message appeared and it would not charge.

Battery depletion or degradation is suspected, but the exact cause is unknown, so please consider it a junk item.

The remote control is lost and not included.
Everything shown in the photos is included.

Please check the photos for all included accessories.
There are also new, unused spare accessories.

The main unit, brushes, and dust bin have been lightly cleaned.
While I have cleaned it as much as possible, there may be some dust and dirt that cannot be removed, as well as scratches and signs of use.

Please only purchase if you understand that this is a used item, has been stored for a long time, and is being sold as-is.
Please note that returns and exchanges are not accepted.

The battery is expected to be shipped installed in the main unit. As a charging error has occurred, it may be depleted or degraded.

[Included Accessories]

Main unit
Home base
AC adapter
2 Virtual Walls
Replacement brushes, filters, etc.
