What's Good About the Bissell Big Green 86T3/86T3Q
Cons of the Bissell Big Green 86T3/86T3Q
Observations
Cleaning attachments for a number of other Bissell carpet cleaners work with the Bissell 86T3.
Minor leakage can also occur when you are making a back stroke with the machine – and that leakage is of small amounts of dirty water when it happens. You can reduce the odds of this happening by emptying the dirty water tank before it fills up all the way, though this does increase the work required to use it.
The carpet cleaner portion cleans carpets well, and while it leaves some moisture in the carpet, it will dry in a few hours. However, cleaning with attachments does not remove as much water, so whether you clean the stairs or specific stains with an attachment, those areas will be wet much longer.
The twenty foot cord should be supplemented with an extension cord if you want to use it commercially.
There is no low water level indicator, though a visual check is not difficult.
Summary
This commercial carpet cleaner is easy to set up and use, as long as the weight isn’t a problem for you. It is a rugged commercial carpet shampooer that, as long as it doesn’t leak, is not going to give you problems. On sale, this model is comparable in price to high end residential carpet cleaners.
