You’ve seen the reviews. Thousands of people swearing that this little puck-shaped machine changed their lives, while others complain it’s basically a blind bumper car that eats shoelaces for breakfast. Honestly, the eufy boostiq robovac 11s is one of the most misunderstood pieces of tech in the home cleaning world. It’s been around for years, and even as we head into 2026, it’s still selling like crazy. But why?
It doesn't have lasers. It can't map your house. It doesn't even have an app. In a world of AI-driven, self-emptying, floor-mopping behemoths, the 11s is a dinosaur.
But it's a dinosaur that actually works.
The "Dumb" Navigation Mystery
Most modern vacuums use LiDAR or cameras to see. They know exactly where your sofa is. The eufy boostiq robovac 11s doesn't know anything. It uses infrared sensors to keep from falling down stairs and a "random" bounce navigation.
If you watch it, you’ll get frustrated. It hits a wall, turns 45 degrees, and wanders off. It might clean the same spot five times and skip the corner of the kitchen entirely. This drives people crazy. They think it's broken. It's not.

The trick is time.
Because it’s so quiet—literally 55 decibels, which is like a quiet conversation—you can let it run for its full 100-minute battery life. Over those 100 minutes, the math of randomness actually works out. It eventually hits almost every spot. It’s not about precision; it’s about persistence.
Why the "S" Stands for Slim (and Why It Matters)
People overlook the height. At only 2.85 inches tall, the eufy boostiq robovac 11s is one of the thinnest robots on the market.
I’ve tested flagship models that cost $1,000 and have more "brainpower" than a NASA satellite, but they’re too chunky to fit under a standard IKEA dresser. The 11s just slides right under. It finds the "dust bunnies" that have been living under your bed since 2019. For many users, that’s more valuable than a fancy app.
The BoostIQ Factor
The "BoostIQ" part of the name isn't just marketing fluff. It’s a pressure sensor system. When the robot moves from a hardwood floor onto a rug, it hears the resistance. Within about 1.5 seconds, it cranks the suction from its standard 1300Pa up to its max power.

It’s great for low-pile carpets.
But here is the reality check: if you have thick, shaggy rugs, don't buy this. It will get stuck. The 11s is designed for "real-world" floors—tile, laminate, and those thin rugs from Target. If your carpet is deeper than 1.02 inches, the 11s will essentially give up and cry for help with a series of beeps.
The Remote Control "Problem"
Everything is an app now. Your toaster has an app. Your lightbulbs have an app. The 11s doesn't. It comes with a physical remote that looks like it’s from 2004.
Some people hate this. They want to start their vacuum from the office. But there’s a segment of the population—and maybe you're in it—that is tired of "smart" things. My parents love this vacuum because there’s no firmware update. There’s no 2.4GHz Wi-Fi pairing nightmare. You just point the remote and press "Auto."
It’s simple. It just works.

Maintenance: The Stuff Nobody Tells You
If you want this thing to last more than a year, you have to actually touch it. You can't just ignore it like a self-emptying model.
- The Dustbin: It’s 0.6L. That sounds big, but if you have a dog that sheds, it’ll be full in 20 minutes. Empty it every single day.
- The Whiskers: Those two side brushes? They get hair wrapped around them. If you don't snip that hair off, the motors will burn out.
- The "11-Switch" Trick: Here’s a weird bit of expert lore. If your 11s stops charging and gives you a solid orange light, sometimes toggling the physical power switch on the bottom 11 times (yes, really) resets the logic board. It sounds like a cheat code for a video game, but it’s saved many a "dead" unit.
The 2026 Verdict: Is It Still Worth It?
Honestly, it depends on your house.
If you live in a 3,000-square-foot mansion with three floors and complex floor plans, the 11s will get lost. It’ll die under a dining room chair and you’ll find it three days later like a lost pet.
But for an apartment, a small ranch-style home, or a single floor with mostly hard surfaces? The eufy boostiq robovac 11s is still a king of value. You're paying for the motor and the brushes, not the software.
Actionable Next Steps
Before you click buy, do a "cable sweep." This is the number one reason people return these. The 11s doesn't have "obstacle avoidance" cameras. It will eat your iPhone charging cable. It will tangle itself in the fringe of a Persian rug.
Spend five minutes zip-tying your cords off the floor. If you do that, the 11s will be the best $150–$200 investment you've made in years. Check the brushes once a week, swap the HEPA filter every few months, and let the little guy do his thing while you watch TV.
You don't need a genius to clean your floors. You just need something that doesn't stop until the job is done.
