The Pure Clean robot vacuum is an ultra low-cost vacuum with no bells and whistles. As a simple unit, this Pure Clean model cleans in a spiral, along the edges, and in a random pattern. Although this vacuum is not built to handle deep suction on carpet and rugs, hard floor types should benefit from the cleaning capabilities this unit offers.

The Pure Clean robot vacuum is designed in a circular shape, contains one bumper wall, and an easy to understand interface on the top, including the filter flap and power button. The power button is the only button on the vacuum, therefore there is no confusion as to what is doing what. Just click the power button and let it clean.

On the underside of the Pure Clean robot is a battery, two spinning brushes, two rear wheels, one front wheel, and a battery charging port. Although it may sound like a lot, the bottom of the vacuum is quite simple.

From an aesthetic standpoint, this Pure Clean vacuum offers an all white color scheme on the top accompanied with their logo embossed to filter flap. By offering an all white design, they have separated themselves from the majority of robot vacuums. Most robot vacuums I have tested thus far seem to follow the grey and black color scheme. In my opinion, the all white adds a nice flare to the appearance of the Pure Clean robot vacuum.

How It Cleans

Unlike most robot vacuum cleaners, the Pure Clean does not utilize a memory or dirt detection system. Typically, robot vacuums offer one of these two technologies, allowing them to either map your home for consistent cleaning cycles, or detect dirt and debris so they can attack it with a purpose. The Pure Clean simply travels around your home, cleaning up messes (if they are there at all) in its path.

That said, the Pure Clean vacuum does clean methodically. Two spinning brushed sweep dirt and debris into its suction path. Additionally, this vacuum cleaner starts by driving in a random pattern, then switches to a spiral patter, followed by cleaning along the edges of your walls, and finishing back in the spiral pattern. By doing so, the vacuum is able to make several passes through the area.

One final note about the way this vacuum cleans, there is no rolling brush. Pure Clean states the reason for this design as the following:

The brushless suction design prevents the automatic cleaner from getting clogged in homes with cat or dog hair.

This explanation is a bit of an over simplification, in my opinion. I suspect the primary rationale to use a brush-less assembly is simply in the interest of keeping costs lower.

Size & Dimensions

With regards to size, the Pure Clean is one of the smallest robot vacuums I have tested to date. This unit is only 2.9″ tall and 11″ wide with a total weight of 3.52 pounds. As with most robot vacuums, the smaller stature of the Pure Clean allows it to drive under furniture and low spaces.

Bear in mind, the smaller design does not mean it will not get stuck when driving under furniture or into those tighter, low spaces. As it gets stuck, cosmetic damage, such as scratches may appear. These scratches should not have any affect on the functionality of the vacuum cleaner, but they are also not going to add any aesthetic benefits to the vacuum. Therefore, I would recommend keeping a close eye on the Pure Clean as it makes its first few runs around your home.

This issue is with respect to virtually all robot vacuum cleaners, not just the Pure Clean.

Accessories & Parts

Cleaning Tests

The following vacuum cleaner tests are designed to show how the Pure Clean performs on different surfaces, picking up a variety of debris types. We test on 3 different floor types, including hardwood floors, low pile carpet, and high pile carpet. For each floor type we test the vacuum cleaner against:

  • Rice – 3 ounces
  • Dry Cereal – 1 ounce
  • Kitty Litter – 3 ounces
  • Sugar – 3 ounces

Each of the aforementioned debris types were spread across our testing lane. The base surface of our testing lane is an engineered hardwood floor. For our carpet tests we slide in a low pile and high pile carpet insert on top of the hardwood floor.

Cleaning test debris types

Testing Debris – From left to right: Rice (3 oz.), Kitty Litter (3 oz), Cereal (1 oz), Sugar (3 oz)

Our vacuum cleaning process strives to be as consistent, fair, and true to real world use as possible. Our tests utilize the following procedure:

  1. Measure the weight of the testing debris and weight of empty vacuum debris container
  2. Spread the respective debris type evenly across the central portion of the testing lane
  3. Run the vacuum cleaner over the testing lane
  4. Measure the weight of the now filled container and take notes on the cleaning performance

Hardwood Floor

After running the Pure Clean through a series of hardwood floor tests, the vacuum proved its performance level for all debris types, except cereal. The smaller suction nozzle of the vacuum cleaner did not allow cereal to be sucked up as easily, leading to only 11% of the debris field being cleaned up. Additionally, the lighter build of the Pure Clean struggled to get over the cereal at times.

  • Hardwood – Rice 99%
  • Hardwood – Cereal 11%
  • Hardwood – Kitty Litter 95%
  • Hardwood – Sugar 95%

Low Pile Carpet

While the Pure Clean robot vacuum is designed to run on hard floor surfaces, it did perform to an average level on the low pile carpet. There was a slight decline in the amount of rice picked up, an increase in cereal, and a decrease in both kitty litter and sugar. The most surprising debris test was the cereal. The friction between the carpet and the Pure Clean allowed the vacuum to crush the cereal and suck it up at a higher degree.

  • Low Carpet – Rice 94%
  • Low Carpet – Cereal 70%
  • Low Carpet – Kitty Litter 44%
  • Low Carpet – Sugar 69%

High Pile Carpet

High pile carpet was the most troubled test for the Pure Clean robot vacuum. The thickness of the carpet prevented the vacuum from moving a majority of the time. Throughout the testing this robot vacuum got stuck with every debris type. Therefore, the highest amount of debris picked up was kitty litter, at 49%.

Bear in mind, this vacuum is designed for hard floor surface types, so the high pile carpet struggles were somewhat expected with the Pure Clean.

  • High Carpet – Rice 15%
  • High Carpet – Cereal 0%
  • High Carpet – Kitty Litter 49%
  • High Carpet – Sugar 8%

Setting up the Pure Clean was straightforward and took no time at all. Once everything has been removed from the packaging, you have to snap in two of the four brushes (two extras are included), plug it in, and send it on its first cleaning. The spinning brushes even have an “R” or an “L” etched into the brush so you know which brush goes where. No tools are needed to setup this robot vacuum cleaner.

As we move onto actually using this Pure Clean vacuum, it’s hard to get an easier. Press the power button and you’re good to go. The vacuum will change modes automatically while cleaning, so there is nothing for you to do but push the power button and let it work.

Once the vacuum has exhausted itself, the LED light within the power button will turn red, meaning it needs to be plugged in and fully charged before returning back to work. Once the battery is charged up, the LED light will illuminate a solid blue color.

There are no bells or whistles with the Pure Clean. Simply press the start button, that’s it.

Pure Clean robot vacuum usability


As a robot vacuum, maneuverability is a strong suit of the Pure Clean. The circular design allows it to turn 360°, the 2.9″ height allows it to slide under low spaces, and the lightweight build prevents it from bumping into objects with a lot of force.

These attributes give the Pure Clean an edge over most upright vacuums, as they may need a couple of passes to really clean around the leg of a chair, whereas the Pure Clean robot vacuum can tightly turn around the chair in one pass.

The biggest issue that faces this Pure Clean vacuum is corner cleaning. Although the circular design provides a decent amount of benefits this is one area where the design hinders performance. The two spinning brushes located on the underbelly of this robot vacuum help give it some reach into those corners, but that does not always leave the corners spotless.

Compared to a more traditional uprights like the Shark Navigator or robots designed to drive into edges (like the Neato Botvac D3), the Pure Clean struggles in this portion of the cleaning cycle.

Pure Clean did include edge-drop sensors with this robot vacuum. These help the unit detect an edge, preventing the vacuum from driving off of stairs or other ledges present in your home.

The following table indicates the frequency at which you will likely want to replace the various parts and components of the Pure Clean robot vacuum vacuum.

Normally, we try to find specifically what the manufacturer recommends for parts replacement. However, we were unable to find this information for Pure Clean. As a result, the replacement frequency below are estimates based on what we have seen is common for other similar robot vacuums.

Maintenance tasks for the Pure Clean robot vacuum include simple things like emptying the dust bin, brushing the filter, and keeping the intake area clean and free of debris. While these tasks are good for prolonging the life of your Pure Clean, this general maintenance will not eliminate the need for replacement parts over time.

Finding and getting replacement parts is difficult. To get replacement parts you must:

  1. Go to the manufacturer’s website
  2. Go the the FAQ page
  3. Find your model
  4. Open a customer service ticket
  5. Deal with customer service to get your part

That process just feels insane to me.

Replacing the battery in a robot vacuum is a must at some point. That said, the process for obtaining a replacement battery for the Pure Clean robot vacuum is not as easy as I would have liked to see. After researching, I was not able to find a generic battery, therefore I had to go through the manufacturer.

As I dove into this process, it began to feel more and more like a hassle. After getting to their website, I was directed to another link for replacement parts and eventually had to create an account with PYLE, the manufacturer,  so my “ticket” could be received. Once this had been completed, a customer service representative reached out to me and helped with the rest of the process.

All things considered, I would have been able to get a replacement battery if needed, but the process was quite daunting.

The Pure Clean robot vacuum is sold at the lowest price point, for robot vacuums, that I have seen to date. Priced in the low tier, this vacuum offers a decent value with respect to the performance. Keep in mind, this robot vacuum is designed for hard floor surface types and low carpet, therefore, limited performance on higher pile carpet should be expected.

Would I recommend this vacuum over a more expensive option that handles carpeted surfaces better? Probably not, unless you are restricted by a tight budget.The Ecovacs Deebot N79 is a little price jump and performed much better during our cleaning tests.

With regards to warranty and returns, Pure Clean is in line with most other robot vacuums. Included with your purchase is a one year warranty and a 30-day return policy, via Amazon.

Pure Clean, a product of Pyle manufacturing, states the following with regards to their product:

…don’t expect it to go between different floor types if there is a barrier.

Personally, I appreciate Pyle’s effort to inform potential buyers about the issues with surfaces that are not hardwood, tile, or other hard surfaces. That said, this vacuum is not for everyone.

Who Should Buy the PureClean Robot Vacuum?

The PureClean robot vacuum is a budget-friendly unit that works best on hard floor surface types. With the simple click of a button, this robot vacuum will take off and clean your floors with three different patterns. If you like the idea of a low price-point robot vacuum, this may be an option worth considering.

I would recommend the PureClean if you’re looking for the following features in a robot vacuum.

  • You have mostly hard floor surfaces in your home – Due to the lack of a roller brush, the Pure Clean robot vacuum really does best on hard surfaces, like hardwoods or tile. The spinning brushes are effective at corralling dirt towards the suction, however, they are not strong enough to significantly agitate carpets, in my opinion.
  • Don’t need added bells and whistles – Added features like wifi connectivity, scheduled cleanings, dirt detection, and smartphone control are just a few features you’ll find on many other robot vacuums, but Pure Clean decided to leave out. Forgoing these features helps to keep the costs down and focus on the basics.
  • Want to spend the least amount of money possible – To date, this is the least expensive robot vacuum we’ve tested (or even seen). Granted, you do get what you pay for, but if the cleaning performance (ie, mostly hard surfaces) aligns with your needs it could be a reasonable option.
  • Have a small space to maintain – The Pure Clean is one of the smallest robot vacuums we’ve tested to date, at under 4 pounds and less than 3″ tall. By the same token, it also has a small dust bin, only holding 0.2 liters of dirt, dust, or other debris. For larger homes, this would likely mean multiple times emptying the dust bin per each cleaning cycle.

The PureClean robot vacuum is a budget-friendly robot vacuum with basic features. The brush-less system relies entirely on the power of suction to clean the floor. During the cleaning tests, it performed decently on hardwoods, but for the carpet tests, the missing roller brush really turned out to be a big problem and the performance suffered because of it. Overall, if you’re looking for an inexpensive robot vacuum and have a small simple space to clean with a hard surface, this vacuum may be acceptable. That being said, for the average home, the Pure Clean is likely going to leave you disappointed.
