When shopping for a smart vacuum, it’s easy to get lost in a sea of specs and features. With so many options out there, I know it’s easy to get overwhelmed. Here’s a breakdown of the most important features I focus on when choosing the perfect smart vacuum.
1 Strong Suction Power
The first thing I look for in a smart vacuum is strong suction power. A vacuum that doesn’t have enough suction will leave dirt, dust, and pet hair behind, making you wonder why you even bothered. I also look for vacuums that offer adjustable suction levels. Some models adjust the suction automatically based on the type of surface they’re cleaning. This not only ensures a thorough clean but also helps extend the vacuum’s battery life.
When comparing models, you might notice suction power rated in Pascals (Pa). For effective cleaning, especially on carpets, I prefer a vacuum with at least 2,000 Pa. The Roborock S7 is an excellent but pricey option, offering 2,500 Pa of suction power.
2 Smart Mapping and Navigation
I don’t want a vacuum that randomly bumps into furniture or gets stuck in corners, and I’m sure you don’t either. That’s why smart mapping and navigation are high on my list of must-have features.
Some vacuums like the iRobot Roomba S9+ use lasers, cameras, or both to map out homes and clean methodically. This ensures that the vacuum knows where it’s been and where it still needs to go.
Many models also let you set virtual no-go zones, so you can keep them out of areas like the pet’s feeding station or your kid’s play area.
3 Long Battery Life
A vacuum that runs out of juice halfway through cleaning is more of a hassle than a help. Long battery life is crucial, especially if you have a larger home. I look for vacuums that offer at least 90 minutes of runtime, but I appreciate models that go beyond two hours on a single charge.
And if the vacuum can return to its dock to recharge and then pick up right where it left off, that’s a big win in my book.
4 Multi-Surface Cleaning
Most homes have a mix of flooring types and the ability to clean all surfaces effectively is crucial. I’ve lived in spaces with everything from concrete floors to thick carpets, and not all vacuums can handle the transition seamlessly.
The best robovacs automatically adjust their cleaning modes based on the floor type. This not only improves the vacuum’s efficiency but also protects floors from unnecessary wear and tear.
For multi-surface cleaning, the Shark IQ Robot Self-Empty XL stands out, offering a self-cleaning brush roll that handles pet hair and debris on various floor types. If you want something more compact, the ECOVACS Deebot T20 Omni is another great option. Some vacuums also include specialized brushes for different tasks, which are particularly useful when dealing with pet hair or hardwood floors.
5 HEPA Filtration
For anyone concerned about air quality—and that should be all of us—a HEPA filter is non-negotiable. These filters trap tiny particles like pollen, pet dander, and dust mites, which are often the culprits behind allergies. Even though I don’t have allergies myself, a HEPA filter ensures that my vacuum isn’t just blowing dust around but actually improving the air I breathe.
It’s one of those features that makes a big difference in the long run, especially if you have kids or pets.
6 Low Noise Levels
I’m not a fan of loud vacuums, especially when trying to relax or work from home. Thankfully, many modern smart vacuums are designed to be much quieter than older models. If noise levels are a concern for you too, I’d recommend looking for vacuums that operate under 65 decibels. Some even come with a “quiet mode” that reduces noise further. This way, you can have your vacuum running while you’re on a work call or watching TV without it becoming a nuisance.
The Eufy 11S Max is one of the quietest models I know, operating at 60 decibels on hardwood, and between 60 and 65 on carpet.
7 Slim Profile for Cleaning Under Furniture
Dust bunnies under the couch? Not with a smart vacuum that has a slim profile. One of the best things about these vacuums is their ability to reach those hard-to-clean areas under furniture. A vacuum with a height of around 2 to 4 inches can easily slide under most beds, couches, and cabinets.
However, not all furniture is created equal, so it’s important to know the clearance under your furniture before selecting a vacuum. Some vacuums like the Ecovacs Deebot N79S (at 2.24 inches) are designed with a low profile specifically for getting into tight spaces, while others might offer a higher profile for increased dustbin capacity or more powerful motors.
You might also consider vacuums with side brushes that extend outwards to catch dust and debris along walls and furniture edges that the main unit might miss.
8 Easy Maintenance and Parts Replacement
Let’s be honest—no one wants to spend a ton of time maintaining their smart vacuum, and I’m definitely in that camp. The easier it is to clean the dustbin, wash the filters, and replace the brushes, the better.
When choosing a vacuum, I check how easy it is to perform these routine tasks. I also consider how readily available and affordable the replacement parts are. A vacuum that’s easy to maintain will last longer and perform better over time, saving me both time and money.
The iRobot Roomba i3+ is one easy model to maintain, thanks to its self-emptying base and simple access to its components. The Shark ION Robot Vacuum R85 also scores high in this regard, with easy-to-remove brushes and filters that can be quickly cleaned or replaced.
The right smart vacuum should make your life easier, not harder. I’ve learned that strong suction, smart navigation, long battery life, and easy maintenance are non-negotiables. A good vacuum adapts to your home’s needs and makes cleaning less of a chore.
