Rotowash r4k SPARES or REPAIRS.
I purchased this to repair but never got round to it. It had been sitting a while when I got it and it's sat in my garage for a year also. I know nothing about them or how it works or what works and what don't.
All the info I can give is If you push the reset button it hums then when it pops back out nothing so there is power to it also the brushes don't turn freely (not sure if they should anyway when not turned on) I've had a quick google and could be cogs, capacitor, bearings it sounds seized up may be a quick fix if someone has worked on them with a bit of a clean and lube. But may be a motor so no idea.
Comes with black brushes which have got to be worth £60 alone.
£60
