Don't waste your money.
According to Simon Fairchild the Zonelia Robot Vacuum N7S gets a 9.7/10 review (2026's Best Robot Vacuum Cleaners-Complete Buyer's Guide). He must have a different machine to me, as mine doesn't clean all the room, it gets stuck near walls or under the furniture. Areas where people actually walk are left untouched. If you request it to go back to the charging station, it makes a few bleeps and then continues what it was doing. Keep pressing the button and eventually it will get the message.
The mapping area shown on my phone bares no resemblance to the room it is trying to clean.
The chat bot on the app is a waste of time as it recommends changing settings that are not available on my app.
I must not be too negative; the suction is good.
However I do feel that my purchase was a waste of money and I would recommend others not to touch this product with a barge pole.
I've just realised that my model is the N7S-U. Maybe the U stands for useless!
