Proscenic’s new M8 hybrid robot vacuum / mop promises new levels of performance, including stronger suction and more efficient navigation. It delivers in that regard, surpassing the impressive cleanliness I’ve experienced with the company’s previous robots. Unfortunately you are connected to a redesigned app with some major connection issues which, for me at least, made the M8’s custom cleaning and mapping features inaccessible.
The M8 looks similar to the M7 Pro we reviewed last year, the most obvious difference being that the control panel with the power and home buttons has been redesigned. A top-centered turret houses improved laser navigation technology that creates more accurate and comprehensive maps than previous generations. For real dirty cleaning work, the M8 combines a rubber bristle rotating brush and a unique rotating brush with 3000 Pa suction. A 2-in-1 module containing a 280 ml trash can and a water tank of 300ml allows simultaneous vacuuming and mopping, potentially cutting cleaning time in half. The robot also comes with various accessories including its charging base, a remote control, cloth mops, a mop holder, and an additional side brush.
This review is part of TechHive’s coverage of the best robotic vacuums, where you will find reviews of competing offerings, as well as a buyer’s guide on the features to consider when purchasing this type of product.
Setting up the M8 is as simple as plugging in the base and placing the robot on the charging pins. It takes 160 to 190 minutes to fully charge, resulting in about 150 minutes of runtime based on usage.
You can control the M8 with its remote control or the new Proscenic app. The app makes more features available, including multi-story mapping, virtual barriers, and cleaning zones. However, the application, which I was forced to update when I opened the old one, has a lot of bugs. Certain screens were not scrolling during the setup process and the app repeatedly failed to connect to my Wi-Fi. Apparently connection failure is a common problem judging by various online reviews. These bugs will likely be fixed in future updates, but they prevented me from accessing some of the M8’s cooler features during my review period.
Fortunately, the physical remote gives you control over all the basic functions of the M8, including starting and pausing cleanings, selecting the mode, and sending the robot to the charging base. You can also use your voice to issue basic commands through the Google Assistant or Amazon Alexa.
I used the M8 for daily cleaning of my lower level, which includes carpets and hard floors. To vacuum directly, you just need to press the “play” button on the remote control. The M8 defaults to auto cleaning mode, which automatically adjusts its suction to the type of floor it is on. When it detects a mat, Proscenic’s Vboost technology automatically activates to increase suction at full power. The suction returns to the previous power level when you are back on hard ground. You can activate maximum suction manually from the remote, but running it constantly in this mode will drain your battery more quickly. There is also a spot cleaning mode for heavily soiled areas.
Vacuuming and mopping together takes a little more preparation. You need to remove the module from the waste bin / water tank and fill the tank with tap water. Next, you place a cleaning cloth on the mop attachment and slide it onto the bottom of the water tank / trash bin module. Finally, reinstall the module in the robot.
The M8 did a great job cleaning my floors. The powerful suction grabbed as much dirt, dust and pet hair as it could reach (its turret kept it from getting under my couch and kitchen cabinets) and its mop was able to remove surface stains and light spills . You’ll still need a mop on hand, as the M8 essentially just wipes a damp cloth on the floor without scrubbing it out to remove deeper dirt. But for daily floor maintenance, the M8 works.
In cleaning performance alone, the M8 has a lot to recommend. But the current version of the Proscenic app made virtually all of its advanced features inaccessible, which is reason enough to get a star out of this review. Proscenic will undoubtedly rectify any app issues, but if you can’t wait, you can check out the Roborock S7, our current pick for the best robot / mop hybrid. It costs a bit more but includes similar features, a more vigorous mop. amd an application without errors.
