Is the Eufy RoboVac 11S Max Worth the Investment? A Full Review
The Eufy RoboVac 11S Max is a budget-friendly robot vacuum that offers simplicity and reliability. With its slim design and solid suction power, it aims to clean your home with ease, particularly in smaller spaces. This review will go through the pros, cons, and everything you need to know about the 11S Max to determine if it’s the right fit for your home.

Design and Features
- Slim Design: The RoboVac 11S Max is designed to fit under furniture like kitchen cabinets, making it ideal for tight spaces where larger vacuums can’t reach.
- Suction Power: Despite its compact size, it delivers decent suction, and you’ll often find the dustbin filled with dirt after cleaning. It uses Boost IQ technology to automatically adjust suction on carpeted areas for improved cleaning.
- Bumper Technology: The RoboVac uses random bounce technology to navigate, bumping into obstacles and changing direction. While it doesn’t clean in straight lines, it ensures full coverage, especially in smaller rooms.
- Physical Barriers: For optimal results, it’s recommended to use physical barriers in larger rooms or areas with lots of obstacles, as the RoboVac relies on its bumper to navigate and may struggle to find its way back to the docking station.
- Scheduling: You can set a cleaning schedule using the remote control, but it lacks advanced scheduling features like multi-day or week scheduling.
Performance and Testing
- Carpet Cleaning: The 11S Max does a decent job of picking up dirt and debris from carpeted surfaces. While it can increase suction on carpets, it doesn’t have the mapping capabilities of more advanced models, so its cleaning path may feel less precise.
- Hard Floors: It works well on hard floors, capturing dust and dirt, but again, the random bounce pattern means it doesn’t follow a set pattern, so some areas may require additional passes.
- Spot Cleaning: The RoboVac can be set to spot cleaning mode, where it will move in a circular pattern to clean specific areas. However, the random bounce system sometimes results in inefficiency, as it may miss spots or move in odd directions.
Maintenance and Ease of Use
- Dustbin and Filter: The dustbin is easy to empty, and the filter needs occasional cleaning. However, its smaller size means you’ll need to empty it more frequently.
- Cleaning the Vacuum: The roller brush, side brush, and sensors should be cleaned regularly to maintain optimal performance. The RoboVac 11S Max is relatively easy to maintain, with parts widely available for replacement.
- Docking and Charging: After cleaning, it automatically returns to the charging dock to recharge and prepare for the next cleaning session. However, in large spaces, the vacuum may get lost and fail to return to the dock.
Pros and Cons
Pros:
- Slim design allows for cleaning under furniture.
- Affordable at $150 (with discounts) – offers good value for the price.
- Boost IQ technology provides better suction on carpets.
- Easy maintenance with accessible parts and filter cleaning.
- Simple operation using remote control for scheduling and cleaning modes.
Cons:
- Limited navigation: The lack of smart mapping or LiDAR makes it inefficient in larger rooms and areas with many obstacles.
- Basic scheduling: Limited to daily scheduling without advanced features like multi-day or specific time scheduling.
- Random cleaning path: The random bounce navigation system may not be as effective as the more advanced straight-line models.
- Physical barriers needed: For large areas, it requires physical barriers to stay in one space.
Conclusion
The Eufy RoboVac 11S Max is a solid choice for those looking for an affordable, no-frills robot vacuum for small to medium-sized rooms. Its slim profile, decent suction power, and ease of maintenance make it a good option for those on a budget. However, its reliance on random bounce navigation and lack of smart features like mapping or smartphone connectivity mean it’s best suited for simple spaces without too many obstacles. If you’re looking for more advanced features and better coverage in larger spaces, consider higher-end models. But for its price, the 11S Max is a reliable performer in smaller areas.
