If you have lots of low-clearance furniture, you don’t want a bulky robot vacuum bumping into it rather than cleaning under it. The $219.99 Dser RoboGeek 23T isn’t the best Wi-Fi-connected robot vacuum we’ve tested, but it has a super-low-profile design that allows it to easily pass under most furniture, and it offers strong suction for its small size. If you can afford to spend a bit more, however, we recommend picking up the $299.99 iRobot Roomba 675 for its superior battery life, navigation, and obstacle-avoidance abilities, though it’s also much larger.
Design and Features
The Dser RoboGeek 23T is among the most compact robot vacuums we’ve tested, measuring 12.5 inches in diameter and just 2.83 inches tall, allowing it to clean under most couches and other low furniture. Design-wise, it looks a lot like the $349.99 Eufy RoboVac G30 (12.8 inches around, 2.85 inches high), but it just a bit smaller all around. The Roomba 675, meanwhile, measures 13 inches in diameter and 3.7 inches high, making it the biggest of the bunch by far.
On top, the 23T has a W-Fi indicator, a power button, and an auto-charging button that sends it back to its charging station. On the bottom it has a main rolling brush, two side brushes, an on/off switch, and anti-drop sensors that prevent it from falling down stairs. It also has anti-collision sensors on the sides.
The vacuum delivers up to 2,200pa of suction, which is a lot of power for any model, but especially especially one this compact. It easily eclipses the Roomba 675 (600Pa), and comes out ahead of the iLife A9 (1,000Pa) and the RoboVac G30 (2,000Pa).
The Dser RoboGeek 23T has a number of different cleaning modes including Auto, Edge, Max, Single Room, and Spot. In Spot mode, it cleans areas for concentrated dirt by spiraling outward about three feet, then spiraling inward to where it started. In Edge mode, it cleans along walls and around furniture legs. If you just need to clean one room, you can put the robot in there, turn it on Single Room mode, shut the door, and it will intensively clean for three minutes. In Max mode, it increases the suction power for a deeper cleaning. Max mode increases the volume and drains the battery quicker. A feature called BoostGen will automatically increase the suction when it detects carpet. Realistically, you’ll probably use Auto mode most of the time.
Dser includes a remote (and AAA batteries to power it), but you can also use the Dserlife app (available for Android and iOS). The vacuum also comes with two physical boundary strips that prevent it from cleaning in certain areas, like under your desk where you have a mess of wires. Dser also included cable ties you can use to tidy up cords to prevent the robot from getting stuck in them, a cleaning tool, an extra set of side brushes, and an extra filter.
To set the 23T up, you need to plug in the charging dock and place it on a hard, level surface against the wall. Dser recommends placing the charging dock three feet away from objects on either side and six feet across from anything. The charging dock has a space where you can store the remote control so you don’t lose it. You then snap the side brushes on the bottom of the robot and activate it using the on/off switch. When you turn it on, the Wi-Fi indicator will start quickly flashing blue, indicating it’s in connecting mode.
From there, press the recharge button on the top of the robot so it goes to its charging dock to juice up for its first cleaning job. While you’re waiting for it to charge, download the Dserlife app and set up an account. When you open the app it asks if you’d like you use Bluetooth; press OK. You can then enable notifications if you like. To register for an account, you enter your phone number, input a code sent to you via text, then create a password.
Once you’re in the app, you press the plus sign at the top right corner and a list of robots will pop up; select the RoboGeek 23T. The app will then ask you to confirm that the Wi-Fi indicator is rapidly blinking. Then just enter your Wi-Fi password, and wait for it to connect.
This is pretty much the same process you go through to connect any robot vacuum to its companion app via Wi-Fi. In testing, I had no issues getting the RoboGeek 23T connected.
The app is simple and easy to use. At the top left you can see the robot’s current battery level, and on the top right it shows the cleaning time. There are three buttons at the bottom: Home (which sends the robot back to its base), Auto, and Remote Control. In the Remote Control section, you can navigate the robot with arrows; enable Auto, Edge, or Spot mode; send the robot home to its changing station; locate the robot if it goes missing by having it sound an alarm; and change the fan speed.
Setting it up to work with Amazon Alexa and Google Assistant isn’t quite as intuitive, but I figured it out and it worked fine. For Alexa, you need to search for and enable the Tuya Smart skill, then sign in with your Dserlife app credentials, and you should be good to go. For Google Assistant, you press the plus button in the top right corner of the Google Home app, select Set Up Device > Works with Google, then search for Tuya Smart and sign in with your Dserlife app credentials. Once you get it set up, you can control the robot with commands like, “Alexa, turn on my 23T,” or, “Hey Google, send my 23T back to charge.”
Before starting a cleaning job, you’ll want to tidy your house a bit and pick up objects from the floor like clothing, loose papers, and pull cords for blinds. Even though the robot has anti-drop sensors, you might also want to use a physical barrier to prevent it from falling down the stairs.
The RoboGeek 23T requires similar maintenance as most other robot vacuums. You should empty the dustbin after each cleaning job, clean the filter once a week, and wipe any debris off the cliff sensors about once a month. You’ll also need to regularly clean the main and side brushes, especially if you have long hair or live with someone who does. Some robot vacuums can empty their own dustbin, like the iRobot Roomba S9+, but they’re a lot more expensive.
The RoboGeek 23T cleans in a random pattern. Most robot vacuums these days clean in a methodical path, making straight lines to efficiently cover a room. The RoboGeek 23T will hit a wall and then turn in a different direction, zigzagging around your home. It still gets the job done, but it won’t make neat vacuum lines on your carpet like robot vacuums with smarter navigation abilities.
It features a 2,600 mAh battery that Dser says allows for up to 100 minutes of continuous cleaning. In testing, it cleaned for 80 minutes in Auto mode before the battery got low. At that point, it stopped vacuuming and started navigating back to its charging station. On its way there, it took a detour to the other side of my house, and I was afraid it would be able to find its way back. But after 25 minutes of searching, it finally made it to the charging dock.
Eighty minutes of cleaning isn’t the best battery life we’ve seen, but it’s not bad. Most of the competition in this price range lasts closer to 100 minutes.
What the RoboGeek 23T lacks in battery life, it makes up for in power. I was pleasantly surprised to see how much dog hair it removed from a white area rug that my brown pitbull Bradley loves to lay on. After one full cleaning job, I could barely see any hair left behind. After two full cleaning jobs, the dustbin was filled with dust, dog hair, feathers from pillows, even a few pieces of dog food.
During those first two runs, the RoboGeek 23T didn’t get stuck once. It even managed to fit under my couch—a spot where many other robot vacuums have gotten stuck—and push out a couple of dog toys from under it. On its next two runs, it got stuck once on a long curtain draped on my office floor, and another time on a phone charging cord on the ground. That said, it’s not uncommon for other robot vacuums to get tripped up in the same scenarios.
The scheduling feature worked without issue. Using the remote or the app, you can select which days of the week you want the vacuum to run and at what time. In testing, it turned on in Auto mode at the scheduled time.
You can schedule it to clean when you’re out of the house, but it’s quiet enough to run when you’re home without it bothering you too much. Dser says the RoboGeek 23T runs at 58db, which, according to OSHA, is quieter than a normal conversation. I can have it on when I’m working, and it won’t disturb me like louder robot vacuums such as the Roomba 675.
Comparisons and Conclusions
The RoboGeek 23T’s size and 2,200Pa of suction power makes up for many of its shortcomings. It’s like a more affordable, less feature-rich version of the $349.99 Eufy RoboVac G30. Both sport a compact design and offer strong suction. The RoboVac G30 has a leg up, offering smart navigation for systematic cleaning and slightly better battery life, but it costs $130 more. That said, we still prefer the $299.99 iRobot Roomba 675 over both of these models. It’s not as compact, but it rarely gets stuck and offers the best battery life and navigation of the three, retaining our Editors’ Choice.
