What is the difference between Dyson v12 slim absolute and v12 detect slim absolute?

When can you actually buy replacement filters? Is that still coming or will there simply be no more to buy? Alternatives? Thanks a lot for your help

Can the charging station of the v11 be used for the v12? I don't want to drill holes in the wall again.

Is the Dyson v12 also good for carpets ?

Does the v11 no longer exist? Does the v12slim replace it? Does this v12 slim have a little longer battery life than the v11?

Is the enclosed Fluffy floor nozzle designed so that there are no scratches on sensitive parquet?
