As far as automated home devices go, they don't come much cuter than robotic vacuum cleaners. You could have a close encounter of the miniature kind with the Lilin K6L or pretend your filthy carpets are a flowerbed and have the lady buggy Vileda Cleaning buzz over them. The hockey puckish Pursonic Elite 600 comes from a company known for scrubbing gobs. No matter how it looks or how good it is at its job, the robovac is earnest, and seeks nothing more than to clean your flooring and get rewarded with sweet electricity for its troubles.
The Moneual Rydis MR6550 is a remote-controlled vacuum and dry mopper that appears to have been inspired by the Stanley Fat Max tape measure. It looks like its diet consists of more than just animal hair and dust, but its girth doesn't stop it from eating the stuff under the furniture. It's powered by a carbonless, brushless DC motor and a rechargeable, 2800 mAh lithium iron phosphate battery, which is supposed to be more heat tolerant and less explosion-prone than regular lithium batteries. There are 5 cleaning modes -- Automatic, Concentrated, Corner, Manual and Reserved -- as well as a Shadow Cleaning mode for reaching beneath objects. The high-efficiency, built-in filter is supposed to eliminate 99.5% of microscopic particles, mold and tiny ticks. A detachable microfiber pad is good at picking up dirt from hardwood, tile and linoleum. There are also numerous, integrated collision- and fall-prevention sensors.
The MR6550 comes with 2 AAA batteries and a remote. According to an Internet video, it also comes with a room barrier sensor, but in case it doesn't, you could probably just close a door. There is a charging dock, but apparently this little guy gets easily lost on the way there and expires from embarrassment. This is a poorly rated robot, but the aforementioned video demonstrates that in something called DJ mode, you can have it bring you coffee, so at least it's useful as a javawalla.
It works great but doesn't totally pick up everything. It goes back over it later then picks it up.
. . . We actually found the Rydis to be much gentler on furniture and baseboards than Roombas; it approaches objects and walls much more carefully.
The MR6550 definitely has the power you need. It runs with a BLDC motor. BLDC motors output 20% to 30% more power than ordinary DC motors.
While the company did send out the other two without hassle, the issue is that they should not break down so easily. Further, the machine does not last long.
We repeatedly found that the 6550 would encounter errors when it darker parts of a room, even when the room was otherwise brightly lit by the sun.
This one has the longest battery life, performs best on my home carpet, runs quietest and has easier dis-assembly and maintenance requirements.
The single rubber pickup roller does a decent job on small dirt, but not very well on bigger things like cereal, small rocks, and candy wrappers.
It's not a heavy duty unit . . . it does supplement normal vacuuming very nicely. We have two cats and two dogs. It's a big help!
Downsides aren’t so much its design flaws or any build-quality issues. You just have to understand the limitations . . . and configure your environment accordingly.
