Really, a bissel big green out clean a truck mount, I don't think so , Haveing owned both there is no way a bissell bgc will even come close to cleaning a carpet aswell as a truck mount. A truck mount has its own engine driving a high powered pum plus its own heat, a bissell cleans at 30 psi and the water coming out the nozzle will ( if you have used a kettle to biol the water first be 50deg F once its been through all the tubing and cooled down.
To clean a carpet properly you need 104 deg f minimum and between 250 and 300 psi and loads of suction , about the same as 10 BGC hooked up together. ( a common myth is that if you have two 100cfm machines if you put them together you would have a 200cfm machine, but airflow doesn't work that way, You have friction and other factors at play)
A typical truck mount will at the machine have 300+ cfm 230-250 inches of water lift and 1000 - 2000 psi variable pressure pump and the ability to boil water if needed
The truck mount also features a vacuum pump with 350 +cfm and 230 inches of water lift at the machine which equils 200+ cfm , and 230 inched of water lift at the end at the wand a bissell bgc will have 80cfm ( depending on model and motornewer ones have less) and 100 inches of water lift at the machine, at the end if the wand the cfm will drop to around 20 due to firction caused by the small diameter pipe.
You canot compare a dincky $ 500.00 machine to a $ 30 000. 00 professionally carpet cleaner.
Bissell bgc are great for car interiors and cleaning up spills and maintaining a carpet but will never be able to out clean a professionally set up carpet cleaning machine, other wise we would all be using bgc and not spending huge amounts of money on a proper machine
