It’s the classic story with many devices. Outside the box, your Robot vacuum It works great but over time, the maximum performance deteriorates and after a few months, it starts performing so poorly that you think it is broken.
However, with robot vacuums, it is very likely that your device will not perform poorly; You’re just unintentionally sabotaging it.
“A common misconception among consumers is that these devices are completely set-it-and-forget-it, requiring no maintenance once they start their rounds,” says Ryan Wu, president of Narwal Americas, a leading global manufacturer of robotic vacuums. “Despite how advanced their automation has become, it’s important to give them a little TLC from time to time.”
Five common robot vacuum errors and how to correct them
The Spot+Scrub is the company’s first wet and dry robot vacuum but it comes with many of the features we’ve come to expect from higher-end models.
There are a number of common mistakes that many robot vacuum owners make without realizing it, some of which can significantly impact your robot’s ability to do its job.
“Most issues manifest as decreased capture and inconsistent coverage,” said Ryan Hruska, senior vice president of product development, robotics, at SharkNinja. “Restricted airflow (full box/base, clogged filter, or clogged path) can make the robot appear to be cleaning while leaving debris behind.” “If your robot vacuum doesn’t have anti-hair-twist capabilities, it may also add resistance, which can increase wear over time. And if the robot has difficulty docking or gets stuck frequently, you’ll often see more partial cleanings and unnecessary battery drain.”
Here are some of the most common problems robot vacuum cleaners face and how to fix them (or avoid them altogether).
Error 1: Not setting up properly before first run
We install and use the app that every robot vacuum comes with, evaluating the ease of use and setup.
The first thing you want to do with any new appliance is start playing with it when you unbox it, especially something as new as a robot vacuum. Before blindly launching it into your home, it’s important that you do some initial preparation.
“It’s very important to set up the vacuum properly before starting your first cleaning session,” Wu says. “Understanding the layout of homes – tight spaces, tight hallways or small corners – greatly benefits cleaning performance. After unboxing the vacuum, users should allow it to complete the initial mapping process.”
Hruska agrees. One drawback, he says, is not completing a quick and ready setup of the robot, “leaving cords, small objects, or marginal rugs in the robot’s path. Most robots, including ours, are designed to navigate around everyday obstacles, but quick pick-ups help ensure the most consistent cleaning.”
It is also important to choose a good place for the dock. “Putting the dock in a tight corner or under furniture can interfere with docking and recharging. Give the dock space so the robot can reliably return and charge.”
The Dreame
After the first run is complete and your robot knows the area it is supposed to clean, you can adjust it for optimal performance.
“Users can make custom adjustments within the app to suit their specific home environment,” says Wu. “By regularly updating the layout and map, the robot always knows where it can and cannot go.”
This is especially important if you moved some furniture or added anything new that might get in the way of the vacuum. It’s also essential after making big changes to your home, such as a remodel, or if you want to dedicate a new area to the robot to clean.
The second mistake: Treating it like a traditional vacuum cleaner
Cordless and robot vacuums can do a great job of cleaning floors, but some are better on carpets.
Another common mistake is treating a robotic vacuum cleaner the same way you would a traditional vacuum Vacuum upright or canister. Robotic vacuum cleaners are intended for frequent light cleaning, not the deep cleaning for which a traditional vacuum cleaner is used.
If you operate your robot vacuum infrequently, it can lead to a buildup of debris that will overwhelm the machine’s brushes and trash can. The same is true if you use it on large messes, such as piles of pet hair, food spills or construction debris.
“Robots tend to perform better when they operate regularly (daily or a few times a week), so they maintain floors rather than trying to tackle heavy buildups,” Hruska says.
We weighed the robot vacuum cleaner’s trash to see how much it picked up.
It may seem obvious but one of the most important things you can do to keep your robot vacuum running well is to empty the trash frequently. Unlike traditional vacuum cleaners, robot vacuums tend to have much smaller trash cans, even if they also have curbside bins. Even a partially full box can seriously affect suction. For models with built-in bins only, you should empty them after each run for optimal performance.
Beyond that, focus on setting realistic timelines based on the size of the home, pets, and flooring. Homes with many pets or deep carpeting are likely to need more frequent trips than homes without pets or those with hardwood floors throughout.
Third mistake: Ignoring the hidden areas that need cleaning in the vacuum itself
Robotic vacuum brushes have gotten better at not tangling hair around themselves but sometimes you still need a helping hand.
Even if you only operate your machine occasionally, there’s a good chance you’re not fully cleaning the most vulnerable parts of your vacuum.
“Besides emptying the trash, it is essential to check and clean the ‘hidden’ places regularly, keeping everything running smoothly,” advises Wu. “When sensors are blocked or brush rolls become tangled, the robot’s mobility and suction power are significantly reduced. It is recommended that you check the brushes, filters, sensors and wheels every few weeks, or more frequently if there are long-haired pets in the home, along with a process that includes simple tasks such as clipping tangled hair. A quick five-minute tune-up is essential for longevity.”
Regular maintenance and cleaning not only improves the operation of your vacuum cleaner, but can also extend its life. For a complete overview of how to deep clean a robot vacuum, check out this Our guide.
Mistake #4: Neglecting digital hygiene and firmware maintenance
The Roomba j7 Plus comes with a charging dock that also empties the robot’s trash. Dirt is collected in handy disposable vacuum bags.
It’s not just the physical robot that needs some regular TLC. A robot vacuum cleaner is a complex electronic device, so maintaining its digital health is equally vital.
“While robot vacuums typically receive automatic firmware and app updates in the background, technical issues can sometimes interrupt this process,” says Wu. “Failure to update may result in persistent bugs or missed performance improvements. Checking for firmware and app updates regularly helps ensure your device gets new features and continues to perform smoothly.”
Updating your robot’s firmware not only fixes bugs and mapping issues but also helps the device run more efficiently and extends battery life. Likewise, app updates can help map an area more accurately or even add new functionality that wasn’t available out of the box.
In some of our own testing at CNET Labs, we’ve seen robot vacuums improve their object-avoidance abilities after firmware updates.
Mistake 5: Not fully understanding the features of cartography and navigation
The Z70 can map the location of objects and will return after cleaning to pick them up.
In the same vein, many owners do not take full advantage of some of the features available in their robot application or the device itself. One prime example is the mapping function. The difference, for example, is between quick mapping, which builds just a basic outline that the robot can follow, or full mapping, which builds a detailed, high-resolution map that may include tight or hidden spaces and optimizes navigation paths. Many models offer more detailed and specific mapping options.
Wu recommends owners “look into the smart planning and scheduling features of their appliances, rather than just running the vacuum on a general cycle for the entire house. By identifying specific ‘no-go zones’ and scheduling high-traffic areas like the kitchen and hallways to be cleaned more frequently than the guest room, consumers will get more efficient cleaning results.”
Many robot vacuums also include the ability to store maps for multiple floors and switch them before starting up, or the option to name rooms or areas and set the device to clean only a pre-selected selection. Spending a few minutes checking out some of the available functions can dramatically improve your bot’s performance and efficiency.
Robotic vacuum cleaners are low-effort, not effortless
Shark’s latest robot vacuum cleaner uses UV light to detect old and dried-up stains on your floor.
As Hruska points out, if you run into a problem, don’t panic.
“If performance suddenly drops, start with the basics: checking airflow restrictions (canister/base/seals), removing debris from the brush stroke and making sure the sensors are clean. Fortunately, most robots today include features like self-emptying bases and self-cleaning brush coils to significantly reduce the frequency of hands-on maintenance.”
Many of the performance issues that arise with robotic vacuum cleaners stem from user error. With proper setup and regular maintenance, a robot vacuum can provide years of reliable service. It’s important to treat your robot as a smart device, not as a disposable tool. It’s also important to remember that as robot vacuums get smarter, digital maintenance may be as important as physical cleaning.
