The visible clean is the first dimension. It is what a cleaner does when they wipe a surface, empty a bin, or vacuum a corridor. Most cleaning companies stop there. Eco Drift does not. A truly clean building requires all four dimensions to be addressed, every time.
Monitoring CO₂ in a meeting room is not about compliance. It is about performance.
Research cited by practitioners including Steven Bartlett on the Diary of a CEO podcast shows that elevated CO₂ directly impairs cognitive function, decision-making speed, and sustained concentration.
As a triathlete who tracks heart rate, power output, VO2 max, perspiration, and recovery metrics daily, Antoni understands this connection instinctively. You cannot improve what you cannot measure. That principle applies to human performance and to buildings in equal measure. The 4D cleaning approach treats a building the same way a performance athlete treats their body: every dimension monitored, every variable understood, continuous improvement built in as standard.
A triathlete does not train by feel alone. Heart rate, power output, lactate threshold, recovery scores, CO₂ during exertion: every variable measured because marginal gains compound over time.
Eco Drift applies the same thinking to buildings. Not guesswork. Not a fixed schedule. Measured, monitored, and improved.
Most cleaning contracts address one dimension. High-performing facilities management requires all four. Here is what each one means in practice.
The surface that can be seen. Vacuumed corridors. Wiped desks. Empty bins. Clean glass. A building that looks and smells clean when your first occupant arrives in the morning.
This is the baseline. It is what every cleaning company promises. It is where most stop.
What cannot be seen. Pathogens on touch points. Bacterial load in washrooms. Contamination risk in kitchens and catering spaces. Cross-contamination from incorrect product use.
A building can look clean and carry unacceptable biological risk. The hygienic dimension requires training, correct product selection, and structured protocols: not just effort.
What is in the air. CO₂ concentration in meeting rooms. Humidity. Air quality after deep cleaning. Ventilation adequacy. The dimension that most directly affects the performance of the people working inside your building.
Research shows that CO₂ above 1,000 ppm in an occupied meeting room measurably reduces decision-making speed and sustained concentration. Most buildings have no visibility of this at all.
The proof that it happened. Geo-tagged shifts. Timestamped task logs. Coverage maps. Performance scores. Monthly reports. Not a verbal assurance. Not a sign-off sheet. A digital record that cannot be falsified.
Data without analysis is noise. You cannot improve what you cannot measure. The verified dimension closes the loop: every clean logged, every deviation flagged, every trend reported.
Research cited by high-performance practitioners including Steven Bartlett on the Diary of a CEO podcast shows that CO₂ levels in occupied meeting rooms directly impair cognitive function, decision-making speed, and sustained concentration. This is not a ventilation compliance issue. It is a performance issue for every person in your building.
At 1,000 ppm CO₂, the impact on complex decision-making becomes measurable. At 1,400 ppm, the impact is significant. Standard room ventilation in a fully occupied meeting room can reach these levels within 20 minutes of a session starting.
Proximetrix monitors CO₂ in real time. When levels rise, your facilities team is alerted before it affects your people's performance. The data is in your client dashboard. The alert is triggered before the room becomes a problem.
When CO₂ rises above threshold, Proximetrix alerts your facilities team automatically. Average response time: under 34 minutes.
Shiftomate, Proximetrix, and Cobots were each built for a specific purpose. Together, they are how the 4D Cleaning Approach is delivered in practice.
Autonomous cleaning units deployed in high-footfall areas. Vacuuming and scrubbing to a consistent standard, every session. Approximately 10% labour cost saving passed to the client.
Explore Cobots →Our own IoT software platform. Real-time CO₂ monitoring, occupancy sensing, and environmental data. Cleaning responds to what is actually happening in your building, not what a schedule assumed.
Explore Proximetrix →Our own field management software. Every shift geo-tagged. Every task logged. Every cobot session recorded. Every performance metric in your client dashboard.
Explore Shiftomate →Antoni Dimitrov, founder of Eco Drift, explains why most office spaces are only cleaned in one of four dimensions, and what a truly clean building actually requires.
The video covers: what most cleaning companies miss, why CO₂ matters for your team's performance, and how the 4D approach was developed from real building data collected at Lakeside North Harbour.
The four dimensions of a truly clean office, explained by Antoni Dimitrov.
Lakeside North Harbour, Portsmouth, is where the 4D Cleaning Approach was developed, tested, and proved. 600,000 sq ft. 2,500+ people. 43 washrooms. 10 years. Three ownership changes. The standard has not dropped once.
Autonomous cleaning in high-footfall corridors. Consistent coverage, every session. Approximately 10% labour saving passed to the client.
43 washrooms deep cleaned quarterly. BubbleFlush reduces a 10-minute descale to 30 seconds. Dryft covers 100m² in 4 minutes. 50% time saving.
Washroom A: up to 600 people per day detected. Occupancy data identified usage peaks. Schedule redesigned around real data. 45 minutes of labour saved daily.
Every shift geo-tagged. KPIs tracked and reported monthly. Client dashboard live. Score improved from 67% to 92%. Benchmarked multiple times by estate management.
Here at Lakeside we continue to transform the workplace experience by introducing smart technologies that enhance cleanliness, responsiveness, and comfort across the campus. These innovations are being delivered in partnership with Eco Drift Commercial Cleaning, using their proprietary Proximetrix platform, a real-time sensor and data system custom-built to improve hygiene and operational efficiency without increasing costs.
