Roborock S4 vacuum bot has the ability to free itself when it gets stuck

By Patrick Hearn September 24, 2019

Robotic vacuum cleaners fulfill one of science fiction’s most intriguing ideas for the future: Self-cleaning machines. No one enjoys vacuuming (least of all cats), but a robotic vacuum cleaner can be everyone’s best friend. The downside is that so many of the current models have a terrible habit of getting stuck on furniture, under couches, and pretty much anywhere else they can get caught. Roborock has solved this issue with the latest addition to its S series, the Roborock S4 — a robotic vacuum with the ability to free itself from obstacles, according to the creators.

The Roborock S4 can clean for up to three hours at a time before it needs to return to its dock to charge. It can transition between carpet and hardwood without affecting its ability to clean, and its heavy-duty wheels let it move between surfaces without getting stuck. Roborock has added more sensors to the S4 (for a total of 11) to improve its fall avoidance, height sensitivity, and its ability to avoid entrapment. its navigation lasers scan the room up to 300 times per minute and create a real-time map that is accurate up to2 centimeters.

The Roborock app works with both iOS and Android and gives you the ability to schedule specific cleaning times, create specialized routes, and control the S4 no matter where you are. You can also create “no-go” zones — areas the Roborock S4 avoids. These zones not only make it easy to keep the Roborock S4 out of areas where it might get stuck, but you can also prevent it from knocking over something important or messing up the wiring of an entertainment system.

It’s worth noting the cleaning features on the Roborock S4, too. It uses a side brush that changes its speed to blow dust into the path of the main brushes, leading to a deeper clean even in hard-to-reach areas. There is also an air filter that helps reduce the number of particles floating through the air after cleaning has finished. Roborock says their vacuum has enough suction to pull such objects as AA batteries.

The Roborock S4 is available today on Amazon starting at $400.

The Narwal Freo X Plus is an entry-level robot vacuum loaded with premium features

The Freo X Plus vacuuming pet hair.

Narwal launched the Freo X Ultra earlier this year, and we found it to be an exceptional robot vacuum and mop combo -- though its $1,400 price tag made it a luxury item for most shoppers. Thankfully, many of the Freo X Ultra's best features can be found on the newly launched Narwal Freo X Plus, which offers an affordable alternative to the flagship vacuum and mop combo.

The Freo X Plus should be much more appealing to frugal shoppers, as it clocks in at just $400. That's a full $1,000 cheaper than the Ultra, yet it still holds up to seven weeks of dust, can lift its mopping plate when traveling on carpet, and produces up to 7,800 Pa of suction to pull out dirt and debris from your carpets. It can even apply 6 Newton units of downward pressure while mopping, allowing it to tackle tough stains with ease.

iRobot launches affordable robot vacuum and mop combo that costs just $275

The iRobot Roomba Combo Essential mopping a floor.

iRobot is one of the most popular manufacturers of robot vacuums, but much of its lineup is locked behind hefty price tags. One of our favorite robot vacuums, the iRobot Roomba Combo j9+, for example, clocks in at $1,400 -- making it a pricey proposition for most households. That's changing today, however, as the brand has officially launched the Roomba Combo Essential, which costs just $250 and offers many of the same features found in its expensive siblings.

The Roomba Combo Essential Robot is a robot vacuum and mop that's billed as an upgrade to the old Roomba 600 Series. It uses a V-shaped roller brush to minimize tangles while vacuuming, offers three different suction levels for customized performance, and uses an edge sweeping brush to better clean baseboards and crevices. It's a similar story for mopping, as you can choose between three different water levels for cleaning hard floors.
