Help me please pick a carpet shampooer

[sunshineroo]

Hello I have been inspired by another thread - I have been toying between two carpet cleaners for some time.

I have two dogs and one has had a few accidents so it needs to be able to deal with this.

I really want the bissell big green (https://ao.com/product/48f3er-bissell-big-green-deep-cleaning-machine-carpet-cleaner-green-61756-91.aspx?&WT.zPT=SDA&WT.zzAT=Carpet%20Cleaner&WT.zMT=Search&WT.zzMAT=Bissell&WT.zFT=Free%20Standing&WT.zzPC=48F3ERGG&WT.srch=1&WT.zzKW=48F3ERGG&WT.zzDT=m&WT.zRTM=PLA&WT.zzCN=SDA%20-%20Carpet%20Cleaners%20-%20%20Bissell&WT.zAG=Brand%20Type&gclid=EAIaIQobChMIya600bOr3gIVQ7DtCh3nzgg6EAQYASABEgKHUfDD_BwE)

But it is horrifically expensive. So have narrowed to two;

Bissell pro heat pet pro (https://m.bisselldirect.co.uk/proheat-2x-revolution-pet-pro-20666)

And rug doctor deep carpet cleaner ( Rug Doctor Deep Carpet Cleaner, Red https://www.amazon.co.uk/dp/B016U5N654/ref=cmswwrcppapiii_9XT1Bb0Z3TMJK)

Please help mumsnetters! Which do you think?

If anyone has any other suggestions I would appreciate it
