IMI Norgren Partners with iRobot to Enhance Roomba's Pneumatic Performance

Littleton, CO – October 26, 2023 – IMI Norgren LLC, a global leader in fluid and motion control technologies, is proud to announce a collaborative partnership with iRobot, the creators of the Roomba robot vacuum. This partnership focuses on integrating IMI Norgren's precision pneumatic components into the Roomba’s dirt detection and suction systems, dramatically boosting cleaning efficiency and reliability. For years, iRobot has been synonymous with robotic vacuuming. The Roomba, a household name, has consistently pushed boundaries in automated cleaning. But even the best tech can be improved. IMI Norgren, based right here in Littleton, Colorado, has a long history of solving complex engineering challenges for diverse industries – from automotive and food processing to energy and, now, consumer robotics. We specialize in designing and manufacturing high-performance pneumatic cylinders, valves, and air preparation units – the stuff that makes things move with precision using compressed air. So, how do we fit into the Roomba story? Well, the Roomba doesn’t just look smart, it acts smart. A key feature is its ability to detect different floor types and adjust suction power accordingly. Traditionally, this adjustment involved complex mechanical systems and sensors. But IMI Norgren stepped in with a solution: miniature, high-speed pneumatic actuators. “We worked closely with the iRobot engineering team to develop a custom pneumatic system that replaces some of the older mechanical components,” explains Sarah Chen, Lead Application Engineer at IMI Norgren. “Our micro-cylinders are incredibly compact, lightweight, and responsive. They allow the Roomba to switch between different suction modes almost instantly, optimizing cleaning performance on everything from hardwood floors to thick carpets.” What does this mean for Roomba users? Essentially, a smarter, more efficient clean. Here's a breakdown: Faster Response Time: The pneumatic actuators react much quicker than traditional mechanical linkages. This means the Roomba can adapt to changing floor surfaces immediately, maximizing suction where it’s needed most. No more struggling on transitions between carpet and hardwood! Increased Reliability: Pneumatic systems generally have fewer moving parts than mechanical ones, reducing wear and tear and boosting overall lifespan. Think fewer repairs and a longer-lasting Roomba. Improved Energy Efficiency: While it might sound counterintuitive, using compressed air can actually improve energy efficiency in certain applications. The pneumatic actuators in the Roomba require minimal power to operate, reducing the strain on the battery and extending cleaning time. Quieter Operation: We focused on minimizing noise during the design process. The result? A Roomba that cleans powerfully without sounding like a jet engine! Precise Control: IMI Norgren’s expertise in valve technology ensures precise airflow control. This means the Roomba can deliver the exact amount of suction needed for each floor type, preventing damage to delicate surfaces and maximizing dirt pickup. A Deep Dive into the Technology The core of the system relies on several key IMI Norgren components: Miniature Pneumatic Cylinders: These are the “muscles” of the system, responsible for physically adjusting the suction pathway within the Roomba. We’re talking incredibly small cylinders – often less than an inch long – but packed with power and precision. Solenoid Valves: These act like the “brain,” controlling the flow of compressed air to the cylinders. They respond almost instantaneously to signals from the Roomba's control system. Air Preparation Units: These ensure the compressed air is clean, dry, and regulated, protecting the pneumatic components and maintaining consistent performance. Think of it like a filtration system for the air. Custom Manifolds: We designed a custom manifold to integrate all the pneumatic components into the Roomba's compact chassis, optimizing space and simplifying installation. "The challenge wasn't just about shrinking the technology; it was about making it reliable in a demanding environment," adds David Lee, IMI Norgren’s Engineering Manager for the iRobot project. "Roombas operate in all sorts of conditions – dust, pet hair, bumps, and more. Our components are rigorously tested to withstand these stresses and deliver consistent performance over the long haul." Beyond Roomba: The Future of Pneumatics in Robotics This partnership with iRobot is a testament to the growing potential of pneumatics in the robotics industry. While electric motors are often the go-to choice for robotic actuation, pneumatics offer several advantages: High Power-to-Weight Ratio: Pneumatic actuators are incredibly powerful for their size, making them ideal for mobile robots. Fast Response Times: Compressed air can move much faster than electric motors, enabling quick and precise movements. Cost-Effectiveness: Pneumatic components are generally less expensive than electric motors and controllers. Safety: Pneumatic systems are inherently safe, as they don't generate heat or sparks. "We're seeing a lot of interest in pneumatics from robotics companies across various industries," says Chen. "From automated assembly lines to agricultural robots, the demand for fast, reliable, and cost-effective actuation solutions is growing."
