Years ago, I used one of those Bissel hand held carpet extractors to deep clean my carpet. It got them clean, the water kept coming up black even after 5 tanks. But it did a horrible job of getting enough water out of the carpet. It took weeks of airing it out overnight with the windows open until it dried enough. Still it would feel wet in spots and mold odors would start to form.
Is there a technique to deep cleaning with these consumer extractors or should I only do this with a professional machine.
For every pass you spray water/solution depending on the type of extractor, you do 3-4 passes dry with no water. Especially with a LGM since its vac isnt the greatest.
