I wouldn't have believed it!
5/5
Honestly, I was going to rip up my hallway carpet and take it up the tip. The marks on it looked so trodden in and worn that I wouldn't have believed it could come clean. We bought the Bissell mainly to clean our cream lounge carpets, but before I wrecked those, I though it best to try this out on the hall carpet where the damage wouldn't matter. However, much to my surprise it cleaned it, it came out brilliantly. Deep ground marks that had been there since the day we bought the house (4 years ago) have now completely gone! I'd still like a wooden floor in my hallway, but until I can afford that we now have carpets that look almost new! This cleaner is amazing. Years ago, probably 20 years ago, we had a trewax industrial carpet cleaner, it was HUGE, noisy, and hard work, it's hard to say for sure but I really thing this Bissell has done much better, obviously I can't do a side by side comparison, but the industrial cleaner was huge and took around 30 litres of the hottest water, and chemicals to add to the waste water as well for defoaming. The Bissell is simple. I don't know if it's the mechanics of the cleaner or the chemicals that has progressed, but it's now easy to clean the carpets and get professional results!!!
