Essential Tips for Choosing the Right Robot Vacuum

When I took on the role of Homes Editor at TechRadar, I was entering uncharted territory.

Like many, I had heard of robot vacuums—those nifty little devices that promised to take the grunt work out of cleaning—but had never experienced their wonders firsthand.

Fast forward 14 months, and I’ve had the privilege of testing a wide array of models, from top-of-the-line machines to budget-friendly options.

Along the way, I’ve uncovered seven crucial insights that I believe every prospective robovac owner should know before making their purchase.

First and foremost, the placement of the base station is critical.

This isn’t just a matter of aesthetics; it’s about functionality.

The base station is where your robot vacuum docks to recharge and, in many cases, empties its dust cup or cleans its mop pads.

It requires a hard, flat surface near a power outlet, with enough clearance on all sides to ensure smooth docking.

Manufacturers typically recommend around 1.5 feet of space on either side and about 4 feet in front.

In smaller homes or apartments, finding such a spot can be quite the puzzle.

I learned this firsthand in my own home, where the only suitable location was under the kitchen table.

Contrary to what you might think, robot vacuums are not confined to a single floor.

Most modern models come equipped with the ability to create multiple maps, allowing them to clean different floors of your home.

Of course, you’ll have to carry the device between floors, but the convenience of having it clean upstairs and downstairs is worth the minor effort.

And for the safety-conscious, rest assured that these bots are smart enough not to tumble down stairs, thanks to their built-in cliff sensors.

When evaluating a robot vacuum, good navigation trumps raw suction power.

Early in my testing, I encountered the now-discontinued iRobot Roomba Essential, which used vSLAM technology instead of LiDAR.

The result was a frustrating experience as the device struggled to navigate my home effectively.

Thankfully, most modern robovacs use LiDAR, which significantly improves navigation reliability, even in lower-end models.

However, keep an eye out for any new models that might skimp on this feature, as it could mean the difference between a smooth cleaning experience and a mechanical nightmare.

Pay attention to the size of the base station before making a purchase.

Some of the latest models come with massive docks, especially those with self-emptying or mopping capabilities.

While these features can be a boon—saving you from frequent manual emptying or mop refilling—make sure you have the space to accommodate such a setup.

If space is at a premium, you might want to consider a simpler model.

Despite the potential space issues, I’ve found that a self-emptying base is worth the added bulk.

Robot vacuums typically have smaller dustbins than traditional vacuums, so a self-emptying feature can save you the hassle of frequent emptying, especially if you have a large home or pets that shed.

This feature can significantly enhance the convenience factor, making the investment in a pricier model worthwhile.

One unexpected delight of owning a robovac is its ability to clean under furniture.

This is particularly beneficial for allergy sufferers like myself, as the bot effortlessly navigates those hard-to-reach areas, keeping them free of dust and allergens.

Recent advancements have seen manufacturers designing robots that can compress their height or navigate without the traditional LiDAR puck, allowing them to fit into even tighter spaces.

Lastly, for those looking to maximize value, opting for an older model can be a savvy choice.

While the latest models boast cutting-edge features, the pace of meaningful technological advancements has slowed.

A robot vacuum that’s a couple of years old often performs admirably for most cleaning needs and can typically be found at a discounted price due to newer models hitting the market.

Just ensure you stick to reputable brands like Roborock, Dreame, Eufy, and Narwal, which consistently deliver quality.

In conclusion, while robot vacuums can be a fantastic addition to any home, understanding these nuances can make all the difference in your satisfaction with the product.

Whether it’s finding the perfect spot for your base station or choosing the right model for your needs, a little insight goes a long way in ensuring you get the most out of your robotic helper.
