Eufy Devices working and not working. (Lowes Hill B61)

Hi does anyone have any eufy devices that they no longer use both working and non working Maybe you have upgraded to a new device or changed brands and they ate just sitting in a drawer or cupboard getting dusty. If so, please consider donating to me . My son is hoping to start an apprenticeship fixing these devices,

Both security, door detectors and vacuum and garden cutting equipment.

If you are able to help it would be absolutely amazing
