Questions about iRobot Roomba i7+ & Braava jet m6

I recently got this combi package. Unfortunately, I have thresholds between 1.4 and 4 cm between the rooms. The Roomba i7 can get over them up to around 2.0 cm. The Braava jet m6 can't get over any of them. Where can I buy the appropriate non-slip ramps so that both devices can get over all thresholds (up to 4 cm height difference)? With the Braava jet, you can specify "thresholds" in the map so that it should also be able to climb (as I understand it). Can you also give me internet links to the products in reputable online shops? Can Galaxus also comment from the official side.

I have owned the iRobot Roomba i7+ for over a year and would now like to add the Braava jet m6: Would this be automatically paired to the Roomba i7+ via the app or would I have to map the flat again for this?

Hello, is it possible to extend the warranty of the appliances?

Hi, we have travertine flooring in our house. I have seen that Braava can only be used with Roomba's cleaner. Is this also suitable for limestone? What happens if we use our special cleaner (ph-value 7)?

As I saw on this page, there is no warranty for this product iRobot i7+ & Braava jet m6, is this true? What should I do in case of failure?

Hello, do you also have the i7 + Braava M6 in black?

Does a residual moisture remain after wet mopping? If so, is this comparable to conventional wet mopping? Are the two devices also suitable for a cat household?

If I am not happy with the quality of cleaning of the products, would I be entitle to return it ?

When is the iRobot Roomba s9+ coming? Whether it comes in a set or not, it would be great if it could be included in the range. Any date known? Thanks for the feedback!

Is the set price only available for the exhibition units? Or also for new goods?

Good day. The set price is not correct in my opinion: iRobot Roomba i7+ unit price CHF 945.- Braava Jet M6 unit price CHF 630.- Total CHF 1'575.- vs. set price CHF 1'599.-...?
