Questions about Miele Wts 510

Do you have to screw the base to the floor where it is or can you just put it on the floor like that? The storage room with the toilet connection has a parquet floor, which I shouldn't damage because it's a rented flat... Merci!

Will this base fit a Miele W1 Powerwash 2.0 & TwinDoc XL (Type:HW18 Mod.: Wmm162 WMM 100-62 CH)?
