Frequently Asked Questions (FAQ)
Q1: What’s the main difference between the Eufy RoboVac 11 and the 11S MAX?
A1: The Eufy RoboVac 11S MAX is an upgraded version of the original RoboVac 11. The “S” stands for “Slim” (it’s even thinner at 2.85 inches) and “MAX” signifies significantly increased suction power (2000Pa compared to the original 1000Pa or 1300Pa of the 11S). While both are excellent, the 11S MAX offers a more powerful clean and quieter operation.
Q2: How often should I replace my Eufy RoboVac’s filters and brushes?
A2: For optimal performance, Eufy generally recommends replacing filters every 2-3 months and side brushes every 3-6 months, depending on usage frequency and whether you have pets. The main rolling brush might need replacement every 6-12 months. Regularly checking these components and cleaning them can also extend their lifespan.
Q3: Can Eufy RoboVac 11 series models handle pet hair effectively?
A3: Yes, the Eufy RoboVac 11 series, especially models like the 11S MAX with BoostIQ technology and stronger suction, are generally very good at picking up pet hair on both hard floors and low-pile carpets. Regular cleaning is key, and some owners find that using specific pet hair replacement brushes further enhances performance.
Q4: Do these Eufy RoboVac models have smart mapping features or app control?
A4: Most models in the Eufy RoboVac 11 series, including the 11S MAX, do NOT feature smart mapping, Wi-Fi connectivity, or app control.

For advanced features like mapping and app control, you’d usually need to look at higher-end Eufy models (e.g., G series or L series).
Q5: What’s the typical battery life for a Eufy RoboVac 11 series model?
A5: A new, fully charged Eufy RoboVac 11S MAX can run for up to 100 minutes on hardwood floors in standard mode.

Q6: Are refurbished Eufy RoboVacs a good purchase?
A6: Yes, certified refurbished Eufy RoboVacs can be an excellent value. They are professionally inspected, tested, and restored to work like new, often coming with a warranty.
