How we examined carpet cleansing machines

For this experiment, I headed to CNET’s product-testing laboratory in Louisville, Kentucky, the place I used a reflectometer and just a little little bit of primary physics to evaluate the efficiency of carpet cleansing machines by evaluating their cleansing effectivity when introduced with quite a lot of the most typical carpet staining substances. 


As you might recall from highschool physics, shade is simply our mind’s interpretation of seen gentle of various wavelengths. As an example, purple corresponds to lengthy, low-energy wavelengths round 700 nanometers, whereas blue and violet characterize brief, high-energy wavelengths, with violet having the shortest of those at solely 380 nm. 

The Electromagnetic Spectrum. Our eyes can solely understand the part within the center. That is what we name seen gentle.

Once we observe a purple apple, two issues are taking place concurrently; the peel of the apple is reflecting solely the sunshine of lengthy wavelength (purple) and absorbing a lot of the different gentle. Our eyes accumulate this info and instantly relay it to the mind for processing. That is how we are able to understand shade (purple, on this occasion) with astounding precision. Chances are you’ll be questioning why black and white aren’t a part of the image above. That is as a result of white contains seen gentle of all wavelengths mixed, whereas black is the absence of seen gentle. 

That is all nicely and good, however how does all of it relate to carpet cleaner testing? Glad you requested.

Carpet cleansing effectivity take a look at

Our eyes can inform the distinction between clear and soiled carpet, however how will we really measure that distinction? In concept, if we might quantify the sunshine mirrored by a carpet pattern (that’s, to measure its “shade”), we might assess the cleansing energy of every carpet cleansing machine by taking shade measurements from a model new piece of carpet and evaluating them to measurements obtained after it has been stained and subsequently cleaned. The ratio of those two reflectivity values (earlier than vs. after) would enable us to evaluate efficiency. In my take a look at logic, the extra related these numbers are, the higher the carpet was restored to its authentic shade. We might repeat this process for each UUT (unit underneath take a look at) and examine the outcomes… So yeah, that is precisely what we did.

A reflectometer sits on a section of white carpet. We use the device to see how closely a given carpet cleaning machine can return the carpet to its original shade after we've spilled something like wine or motor oil on it.

Contained in the search unit, there is a tristimulus filter that forestalls different sort of sunshine (i.e. UV and IR) from interfering with the readings, and a photograph sensor that measures the quantity of sunshine mirrored from the floor of the take a look at topic — our white carpet.

Enter the reflectometer, a tool of many color-matching purposes in industries like textiles and paints. Happily, the working precept of the reflectometer is relevant to our functions, as nicely. Our Photovolt Mannequin 577PC Reflectometer has a search unit or “probe” that homes a tungsten bulb that emits gentle in all instructions inside a chamber after which measures how a lot of that gentle is mirrored again to its photosensors. This measurement generates a voltage that’s linearly correlated to the quantity of mirrored gentle perceived by the photosensor, which permits us to quantify gentle and shade. Science!

We’ll use the whiteness index as our body of reference. This parameter is used to measure how “white” a pattern is by measuring its reflectance underneath two totally different gentle filters, blue and inexperienced, then utilizing an equation to correlate and normalize these values. Since we will probably be utilizing white carpet for this take a look at, getting WI values from earlier than and after provides us an correct illustration of how a lot of the soil and stain was successfully faraway from our carpet by every carpet cleansing machine. 

So, we segmented 4 6-by-6-inch “stain squares,” every to include one sort of soil. We positioned the search unit on prime of the model new white carpet pattern and measured its WI. To make sure repeatability and accuracy, we took 5 readings at totally different areas inside our soil sq. and averaged the reflectance readouts. 

We chosen 4 substances for staining:

  • 150ml candy purple wine: A sugary, alcoholic substance with confirmed staining energy.
  • 150ml black espresso: An acidic, on a regular basis substance containing tannin, a naturally occurring dye.
  • 150ml motor oil: Our oily stain of selection. Powerful to take away because it does not combine nicely with the water disbursed by the UUT.
  • 60g marinara sauce: An natural, tomato-based substance that proved to be the hardest stain to take away.

We proceeded to soil the squared sections, permitting the contaminants to accept roughly one hour. Then, we started the cleansing course of. Two cleansing cycles had been carried out on every stained sq.. A cleansing cycle consists of two moist strokes, adopted by 4 dry strokes. Lastly, we measured reflectivity values on the similar 5 areas as beforehand and averaged them. The ratio of ultimate vs. preliminary WI values tells us how environment friendly the carpet cleansing machine was at restoring the carpet to its authentic white.

The powerful mess take a look at

CNET lab associate Eric Snyder measures marinara sauce into a cup on a scale, ensuring the exact same amount is used for each tough mess test.

Marinara sauce proved to be the hardest sort of soil to take away. Since each cleaner had such a tough time eradicating it from carpet in simply two passes, we thought it deserved its personal class. Therefore, the powerful mess take a look at. 

For this problem, we adopted producers’ suggestions to set every cleaner to its “max” or “powerful mess” setting and carried out any extra cleansing steps resembling pretreating with a supplied chemical substance, pretreating and cleansing with steam, and so on. We modified the WI equation in order that it is extra appropriate for comparability, and we carried out the identical process for taking shade measurements and evaluating the WI values. 

A before-and-after shot showcases the results of CNET's tough mess test for carpet cleaning machines, where each cleaner does its best to clean marinara sauce off of a white carpet. None of the cleaners we tested removed the stain outright, but some were a lot better than others.

Marinara stains are a troublesome, tomatoey mess.

Let’s needless to say the take a look at has been designed to be arduous. To make sure comparability, the models had been solely allowed to scrub in a restricted and managed method. Extra importantly, the WI equation assumes that the pattern underneath the reflectometer is fairly near true white. White printer paper is 91% white, whereas our carpet is 55%. It is the whitest carpet we might discover, however it’s not that white. So do not be shocked if the scores appear low general. 

Here is a enjoyable reality: Throughout this experiment, we carried out a complete of 700 measurements, all to give you the fitting info for making an knowledgeable buy choice that meets your wants. The desk under summarizes the outcomes, and bear in mind, greater scores are higher.

The outcomes are in. Take a look at how totally different fashions examine to 1 one other when it comes to cleansing efficiency (greater scores are higher).

Different carpet cleansing machines we have examined

Bissell Hydrosteam Pet Mannequin 3423: I had excessive expectations from this mannequin because it’s one of many pricier ones on the market, however it solely proved able to posting the third-lowest rating in our powerful mess take a look at. Regardless of utilizing steam shelling out expertise for pretreating and cleansing carpet, the efficiency left us unimpressed. 

Bissell ProHeat 2X Revolution Pet Professional Mannequin 3587: This unit had a surprisingly excessive rating in our powerful mess take a look at, rating third on this class with a good rating of 66.1. It did not rating fairly as excessive when cleansing different stain sorts, although — in actual fact, it ended our assessments with the third-lowest cleansing rating general. It comes with a two-in-one upholstery instrument, three-in-one stair instrument, a 3-inch deep stain instrument and a really handy tray for cleansing out the unit, however we predict there are higher choices on the market. 

Hoover Professional Clear Pet Carpet Washer: One of many least costly fashions of the bunch, however its efficiency wasn’t that nice. For starters, this Hoover was the one unit to get a “fail” rating in our take a look at. Within the case of marinara and motor oil, it even appeared to unfold the soil alongside its path on the carpet, which is rarely good. 

Bissell Crosswave Hydrosteam All-In-One Multi-Floor Cleaner 3515 Lowest performer in each our cleansing effectivity take a look at and difficult mess take a look at. It was very arduous to push this unit alongside our low-pile carpet, most likely as a result of the cleansing brush roll is stopped by friction in opposition to the carpet threads. Highlights of this product embrace steam shelling out functionality and that it may be used to scrub different surfaces like wooden flooring.
