How the new generation of i-mops masters the Sinner’s Circle
Are you tired of expensive equipment and complicated maintenance which often leads to frequent breakdowns? These challenges not only drain your budget but also lead to wasted resources like water, energy, and time: ultimately resulting in inefficient, labor-intensive processes.
What if there was a smarter way: one that simplifies maintenance, reduces waste, and boosts performance?
That’s exactly what inspired the evolution of the i-mop. For years, cleaners have been extremely happy with its superior cleaning performance, which set a new industry standard. Now, with the launch of the i-mop 40 and i-mop 40 Pro, we’re raising the bar even higher. With over 10 years input from the market and users, these new models are designed to take your cleaning efficiency to the next level. This is clearly evident by examining the Sinner’s Circle. This visual tool explains the four key elements of effective cleaning: time, temperature, cleaning agent, and mechanical action.
In this article, we’ll explore the latest improvements in the i-mop 40 series and how they optimize all elements of the Sinner’s Circle to achieve flawless, high-performance cleaning results.
What is the Sinner’s Circle?
In the late 1950s, German chemist Herbert Sinner introduced an insightful model to explain the dynamics of effective cleaning. Known as the Sinner’s Circle, this concept identifies four essential elements that work together to achieve optimal cleaning results: mechanical action, cleaning agent, temperature, and time.
1. Mechanical action
This refers to the physical effort involved in removing dirt, such as scrubbing, brushing, or wiping. Variables like speed and brush pressure also play a key role in how effectively dirt is loosened and removed from surfaces.
2. Cleaning agent
The cleaning agents, like detergents or disinfectants, break down dirt, grease, and microbes, making them easier to remove.
3. Temperature
The temperature of the cleaning solution influences how well it works. When at the right temperature, the active ingredients in the detergent are more effective, helping to break down dirt and residues faster.
4. Time
More contact time usually leads to better results. If time is limited, cleaning performance can be improved by adjusting other factors, such as temperature, mechanical action, or the type of cleaning agent.
Why balance matters in the Sinner’s circle
The four elements of the Sinner’s Circle can be visualized in a circular diagram, each initially contributing 25% of the overall influence. These variables are interdependent. Reducing one component will require increasing one or more of the others, and vice versa. This creates an unlimited number of possible combinations, although only some will lead to effective results for the user. That’s why understanding the Sinner’s Circle and how all elements interact is crucial for efficient cleaning.

How our new i-mops improve the Sinner's Circle
The i-mop 40 and i-mop 40 Pro improve all four aspects of the Sinner’s Circle by requiring less physical effort, reducing the use of cleaning agents, allowing the use of different water temperatures, and ultimately improving efficiency and saving time.
Effective cleaning in less time
Time is money and we are aware of that. The new generation of i-mops is designed to optimize this essential element of the Sinner’s circle and, in turn, save you money. With superior mechanical performance, the new i-mops clean 75% faster than traditional mops and 20% faster than similar-sized scrubber-dryers. This means you get more done in less time.
Less detergent needed
We all know that excessive use of cleaning agents can negatively impact the health of people around. So, how can you reduce them without compromising on results? The answer lies in smart innovation.
The i-mop 40 and i-mop 40 Pro are equipped with an advanced water distribution system that delivers exceptional cleaning performance while using less cleaning solution.
Another smart feature that supports this is the integrated lift kit. By lifting the squeegee slightly during cleaning, the solution stays on the floor longer, giving it more time to work. This means you can use less detergent without compromising on results. It’s a simple adjustment that makes a big difference for people and for the planet.
Robust mechanics
The Sinner’s circle suggests that longer contact time with the surface leads to better cleaning results. This is true, but what happens when the power of your mechanics increases?
The new generation of i-mops proves that powerful mechanics make a difference. Their robust counter-rotating brushes break down dirt efficiently, leaving surfaces up to 90% cleaner than manual mops. As a result, both the time and detergent needed for the job are significantly reduced.
No heat, no problem
Even though it's often assumed that hotter water means better cleaning performance, the i-mop 40 and Pro are designed to work effectively using room temperature water. Thanks to their mechanics, there's no need for high temperatures to achieve outstanding results. This gives cleaning professionals the flexibility to tackle a wide range of tasks using just tap water, reducing energy consumption while still maintaining exceptional performance.
For heavily soiled surfaces, you can still opt to use warm water to speed up the cleaning process. You can use water with a temperature up to 45°C.
What are the key improvements of the i-mop 40 and 40 Pro?
The latest generation of i-mops introduces three key innovations: modularity, circularity, and serviceability. Every improvement is designed to save time, money, and effort, while helping you optimize the Sinner’s Circle for maximum cleaning effectiveness.
Enhanced modularity
The body, deck, and motor of the i-mop 40 and i-mop 40 Pro can now be easily separated. This allows service technicians to quickly identify, remove, and replace faulty parts directly on-site. This minimizes downtime and improves the user experience.
Extended lifespan
Sustainability is a major focus. The new i-mops feature a Self-Diagnosing System with a smart light indicator that clearly communicates the machine’s operational status. This enables users to act quickly, take preventive measures, and avoid unnecessary interruptions.
Additionally, all electronics have been relocated from the bottom to the top of the machine. This redesign reduces the risk of water damage to electronics and extends the life of the machine.
By making the i-mop easier to repair and maintain, we reduce waste and support a more sustainable future.
Better ergonomics
The i-mop 40 and i-mop 40 Pro are designed with ergonomics in mind, featuring the i-balance system, which uses a spring mechanism to support the machine’s weight and reduce physical effort. It also keeps the i-mop upright when not in use, preventing tipping. Both models include an adjustable handle and improved grip to reduce strain, making longer cleaning sessions more comfortable and less tiring.
More efficient use of water and cleaning agents
As mentioned before, the i-mop 40 and i-mop 40 Pro are equipped with an advanced water distribution system, making sure there is no excessive use of water. They also feature a user-friendly click-on squeegee system, allowing users to temporarily lift the squeegee when needed. This is especially useful when using detergents that require dwell time, allowing the solution to stay on the floor longer for deeper cleaning.
Clean smarter, not harder with i-mop 40 and i-mop 40 Pro
The new i-mop 40 and i-mop 40 Pro are a step forward in smart cleaning. Purposefully designed to enhance every element of the Sinner’s Circle, they combine powerful mechanics, improved ergonomics, and efficient use of water and cleaning agent to deliver exceptional results with fewer resources. No more wasted time on breakdowns, excessive water use, harsh cleaning agents, or long cleaning sessions. Instead, enjoy a cleaner space, a smaller environmental footprint, and a tool you can count on, every day.
