I also fell for the rug doctor scam and want to share my experience to prevent other victims.
I rented the machine to clean out the carpets before the check-out inventory of the flat I was renting.
I collected the machine from a cage in ASDA and it was filthy! and no one there to mention anything.
The machine itself is so poorly engineered it seems fit for The Flintstones.
It's so heavy that it's already a fit to get it home from wherever you collect it from, let alone trying to manoeuvre it around the small spaces of a typical residential property.
No problem, I thought, I'll rent the upholstery tool as well.
Little I knew that the upholstery tool was unusable due to an unavoidable kink that was generating in the hose which made it spray water all over the place randomly.
By the way, if you wonder how to drain the tank and are up for a good laugh call the customer support, it's absolute genius! The manager will tell you either keep spraying all the water out from the tool until it's finished or take the machine out of your home, tilt it and dump everything outside there and then! DISTURBING!
As a result, after hours trying to get some value off the rental cost, I ENDED UP HAVING TO CLEAN MANUALLY AFTER ALL THE MESS THE MACHINE HAD MADE!
I complained on the phone requesting a refund and all they had to say, including a manager! was that they would lend me the machine for another day for free!!! Not only they do not understand THAT I DON'T WANT TO BREAK MY BACK EVER AGAIN WITH ONE OF THEIR RIDICOLOUS MACHINES but they are not even receiving the fact that their proposal makes no sense anyway as I needed it for the checkout cleaning!
We went on and on and on about this and said they would send an engineer to check the machine for any issue and will let me know. To add to the INSULT, they said if they found any issue with the upholstery tool they would refund me the 2 or 3£ of it, when I have spent NEARLY 50£ between rent, accessories and detergent. Never mind that you CANNOT MAKE ANY USE OF THE MACHINE WITHOUT THAT TOOL!
Have they ever contacted me back? NO
Put the hard cost together with all the time you'll spend collecting the machine, cleaning it up at the start, trying to make a use of it, re-cleaning it after use, bringing it back to the shop, finding another way of doing the cleaning when you figure out THE MACHINE HAS MADE YOUR CARPET WORSE, spend the time complaining on the phone.
IS IT WORTH IT? NO
Check on SHPOCK, you get mobile cleaners which do a professional job for the same money.
Or spend a little more and buy a decent machine that you then keep.
