The Eufy Robovac 30C is an upgrade compared to the 11S. The short version is that the 30C offers higher suction power, connectivity, and ease-of-use features than the 11C but it comes at a higher price tag. If you want a more advanced robot vacuum, choose the 30C; if you want to save some money, choose the 11S.
The 11S is an older model, but it still offers great value at a friendly price. This robot vacuum is a good choice if you are on a budget. It’s among the cheapest options available from Eufy.
Though low priced, the 11S is a capable vacuum for cleaning up bare floors and low carpets. It has 1,300 Pa suction power based on the BoostIQ technology that’s enough for most floors and some low pile carpets. If you want to use it for cleaning high pile carpets, it will be tough with the 11S – though that can be said for most robot vacuums.
This vacuum can also handle picking up pet hair. It comes with bristled brushes that catch the pet fur quite well and prevents any tangling of hair with the V-shape of the brush. With the 0.6L dust bin, there’s enough space for it to clean a decent area before needing to be emptied.
The 11S is 2.85 inches high, making it a slim vacuum that avoids getting stuck under furniture, as long as there is enough clearance. It’s also a quiet vacuum, running at around 55 dB noise level, similar to the sound of a refrigerator or air conditioner.
With the infra red remote control, you can manage the Eufy from a distance of 13 ft. It means you don’t have bend down to fumble with the onboard buttons.
The 30C offers more advanced and complete features than the 11S. First, it has higher suction with 1,500 Pa BoostIQ power in Max Mode, allowing the 30C to clean medium pile carpets thicker than the 11S can. The normal mode can be used when cleaning bare floors to reduce the noise level.
It also has smart home connectivity through 2.4 GHz WiFi connection that can hook up to your phone or Alexa. This feature isn’t available on the 11S. Other than that, there is a feature to quickly find where your vacuum is with a button, in case it gets stuck or you want to shut it down.
The similarities between the 11S and 30C include having the same height of 2.85 inches and use obstacle and drop sensors for their navigation to avoid falling or bumping into walls.
The V-shaped brush is on both models allowing for tangle-free cleaning, use the same HEPA filters that can capture 99% of allergens (but not particles smaller than 0.3 microns), and they both can run up to 100 minutes with their batteries.
