Hello, I absolutely must get a robot vacuum cleaner-washer with an emptying station, but it's incredible that we can't see these appliances working live, so that we can choose in a less risky way than is currently the case! Especially via sites that don't give refunds at all, but force us to choose something else in their shop, but me, I need this amount in return if I want to choose another brand that the store doesn't sell! It's really not normal, not to say "disgusting" that it's only the customer who takes the risks! Well, on Digitec and Galaxus, I hope it's not a real hassle to get your money back if it doesn't fit once you've tested it: I know they deduct 10% if you've unpacked the item if you've unpacked it...which is also stupid, because how can you say that the art. doesn't work properly, or isn't suitable if you don't have to take it out of the box ???? It's a scam, but at least you can get back 90% of the amount you paid, which is not bad! And since the advent of social networking, small shops have been closing down one after the other and we're forced to go online to find things like a robot hoover - and I'm very, very suspicious of this method of consumption, having fallen victim to online suppliers several times. And I've been saving up for this purchase for months, so getting ripped off would be catastrophic! I therefore deplore the fact that there are no longer any shops that are real advisers, and give us a demonstration of the art.like these and from several brands, because there we have to waste hours and hours reading comparative tests external to a specific brand, watching "unpacking" by professional testers who film everything on film. of professional testers who film everything from unpacking the product to a plethora of explanations, except that this remains subjective, because you watch 3 or 4 of them, and of course, they don't all have the same opinions!! So, especially when you CAN'T make a mistake, making the right choice is extremely difficult. So, today I'm asking the community to help me choose between the dreame 20 complete, the 20 ultra and the dreame L10 S Pro Ultraheat, which is the best? A thousand billion THANKS for your help,
