The Seebest C561 Multifunctional is an automated vacuum cleaner with mopping and brushing functions that turn it into an all-purpose floor scrubber selling at a reasonable price. It comes with the standard robovac essentials, like a virtual wall to keep it from wandering off-mission and a charging dock that it will return to obediently when its energy starts to flag. Assuming it works as advertised its capabilities are strong, but reviews online are scarce, with a couple of good ones and an abysmal one on Amazon that suggests that all support and replacement parts on the unit have to come from China, meaning that you'll probably be fixing it yourself when something goes wrong. If you can find it at the right price, though, it might be worth the gamble.
There's a lot of assembly and programming involved in getting the C561 up and running, enough that the manufacturer has put a lengthy video on YouTube to show you how to do it. Be warned that watching this video may scare you away from buying this unit -- the instructions are complicated -- but at least the company provides pretty clear details that only occasionally drop into bursts of Chinese. The unit comes with a remote control that should simplify operating it once you have the initial assembly and programming over with, so getting it up and running will, with any luck, be a job you only have to do once.
These sorts of complications are the price you pay for getting a bargain bot. If you aren't the DIY type, you might want to look at robocleaners from higher-end companies that sell their products with a higher-end price tag. Some candidates include the Ecovacs Deebot R95 and the iRobot Roomba 880 robovac. Or for an even cheaper all-purpose floor cleaner, look at the Liectroux Robot Vacuum Cleaner.
Not very noisy. The robot is powerful enough to climb over carpets, wires and so on. Accessing the brush rolls is easy.
It can’t climb over thick carpets and doesn't have a HEPA filter.
