Can you please explain?
The deflector is a very important part of the puzzle. Keep in mind that the wide angle reflector only serves to increase the coverage to 135 degrees but it does not change the hot spot. The hot spot still very closely resembles that of a smaller reflector. Adding the deflector reduces the level of the hot spot while increasing the size.
Part of the problem people have when trying to render a white background is that you have a hot spot and then all the areas outside the hot spot where the light is falling causes gradations. When this happens you have two choices. You either expose the background correctly for the hot spot and deal with the gradations or you expose for the corners or edges, causing the hot spot to be driven very far into clipping and excessive amounts of light return to the subject area, often causing wrap, ghosting and halos.
When the hot spot and the overall coverage are increased you virtually eliminate the rapid falloff and gradations and this means you have more control, can work your subject closer to the background without wrap, and cut out tons of unnecessary time at the computer doing post processing.
='[godfather];7989080']Also I understand how the BG got the pure white BG but what about the floor?
The sweep at the bottom of the seamless is getting the same amount of light as the middle or edges and the floor behind the subject is also receiving very even lighting due to the wide angle reflector. That light is slightly higher in output because it's the light that is not deflected and is coming out the side of the deflector and wide angle reflector so when it reaches the floor the level is reduced to just about the same level as that of the background.
The subject is lit with a 53" Octa and a large white reflector is used for fill. Since the subject is sitting on the floor, the combination of falloff from subject lighting and the light reflected from the background renders the floor around the subject white with some small areas that are 1/10 to 2/10 stop under but do not show any gradations.

Hi Robert, can you post link to the wide angle reflector you mentioned(as there are quite some reflectors on your gear list)? I am using genesis and hopefully I can make use of this reflector as well as I got small spaces as well.
This is the 135 degree wide angle reflector:
Despite the fact that every image I've ever seen of this reflector appears to have a silver interior, the reflector actually has a white interior which makes for very nice light.
As mentioned above, just having the reflector is not the complete solution. You'll also need the mini silver deflector. Unfortunately you can't just buy the silver, as they are sold in sets which include one silver and one gold.
