Weeell, Its pretty good.
Might I suggest a Festool ETS 125 instead of a Worx WT645K Electric Palm Sander?
For the motherboard, I'd suggest a different color instead of orange. Because orange is gross.
Also, The roomba is probably a lot better than the HOOVER.
Everything else is pretty good, But, Try the Oster 6056 instead of that black and decker.
