I'd like to discuss a line of carpet cleaners that I've always been fascinated by: the Bissell ProHeat, specifically the ones produced from the early to mid-2000s.
They were primarily made out of glossy black plastic (other colors were available), and have a hood design that I always thought resembled Darth Vader from Star Wars.
As the name implied, the big selling point was a built-in heater that made the water up to 25 degrees hotter for more effective deep cleaning. They utilized a 2-in-1 "Tank-in-Tank" where the clean water went into a vinyl "bladder," whereas the recovered dirty water collected around the bladder, so that the clean and dirty water would never mix. This was supplemented by a "SmartMix" system where the formula would be poured into a separate, smaller tank, and then the user would turn a dial to control how much solution would be mixed in with the clean water, depending on how soiled carpets were.
At the heart of the machine was a DirtLifter PowerBrush with either 5 or 6 rows of bristles, driven by a rubber "pump belt" along with a geared "brush belt." Replacing the pump belt added an additional cost of ownership to the machine.
These machines also had a built-in flex hose, accessible by simply turning a diverter dial at the base of the unit. The heater did not work through the hose, though. Attachments included a tough stain tool and a spraying crevice tool; higher-end models included a TurboBrush with an air-driven brush roll.
One interesting attachment was a "Scotchgard Applicator"; it consisted of a sprayer which attached to a bottle of 3M Scotchgard carpet protectant. The user could then spray Scotchgard directly into the carpet, similar to using a garden hose, for better protection against stains.
There also existed a bare floor tool for this machine, allowing it to clean most floors. However, the ProHeat could NOT be used on hardwood.
Bissell went a bit wild with adding novel features to this line of machines; there was a model with a "Perfect Pass" speedometer (ProHeat Pro-Tech) as well as a Self-Propelled machine.
Now for my own stories. Sometime around 2003, my dad and I were at either Lowe's or Home Depot; he almost bought a ProHeat, but then changed his mind at the last minute and walked out of the store, leaving the cart with the machine out in the open.
My grandma owned a ProHeat ClearView back then, but I never actually saw her using it. One time, when I was 11, I was visiting her house, and used a screwdriver to take apart the machine at the brush roll area. I had previously watched a maintenance video (powered by Vendaria) on Bissell's website to learn how to do it. That brought me a step closer to learning vacuum maintenance. I also messed with the tanks and dials on the machine, although I never used it myself. One time, the belt access door had been removed (and presumably lost), and I saw that the pump belt had a bunch of cracks in it. The machine eventually broke after a few years of use, and she eventually tossed it in the trash.
I recently watched a YouTube video from VacLab, and discovered the ugly truth about the amperage: despite being labeled as 12 amps, it was actually split between the suction motor and the heater. So essentially, half of the machine's power is being used to simply heat the water, resulting in a weaker suction motor.
To those who have owned any of these machines, what were your experiences with them like?
