According to the description, we have not yet installed it to test it, it arrived with memory as we asked.

Arrived quickly, a little charged. I took it purely for crumbs in the kitchen. Do not expect much from him… he goes there for half an hour here, chaotically, collects only hair and wool normally, with crumbs trouble… Then he gathered you, drove and spat it out. Well, in short, the request is not satisfied) but at least something collects and thanks for that)
