The last robot vacuum I had was an iRobot I purchased from Costco for $399 4 or 5 years ago. It was new technology back then but didn't impress me. It just didn't clean very well and pushed things around, made loud noises scared my little dog, no wifi connection, no remote controller. It was a dumb gadget. So I had always been against the idea of getting a robot vacuum because I thought they were scams. I left it to my ex-girlfriend when we broke up. But this one changed my mind. The technology is greatly improved, I realize I am actually living in the future.
>The look. A glass looking thick plastic covers the top of the robot, makes it look modern and expensive.
>Operation. There are only two buttons on the robot. You will need to use the remote or app to control most of the functions. Two side brushes and one roller brush act as the arms of the robot that collect all the dust and debris. There are 4 side brushes come with the package. Advised to replace them every 3-6 months. You can find replacements for 20 dollars on Amazon. Vacuum power is said to be 1600 PA, which is quite strong for a robot vacuum. It really sucks.
>The App, remote Alexa. The remote is good, but the app is better since you can use the app to control the robot everywhere that has reception. It's fairly easy to connect the robot to wifi. To connect to Alexa is trickier, and it just doesn't worth the time because you simply can do all the things through the app. You can only use Alexa to send out two demands to the robot - on and off. You can not home the robot through Alexa. The good thing is you get to name the robot and call it by the name if you use Alexa commend. My robot's name is Spidie.
>Pet owners. I have a long hair GSD and it sheds a lot. The robot has no problem picking up pet hairs. The robot is pet-friendly, even my little dog which is very shy and sensitive, she doesn't mind the robot clean her bed and pick up her kibbles.
>carpet or floor. I think the robot works best on wood floors. It doesn't work on high carpets, it will get stuck.
>Noise level: very quiet. I can have the robot do its job while I sleep. It only makes noises when it bumps into things, though It does a good job to avoid most obstacles.
>Stairs. No worry at all, it doesn't fall. I worried about it too when I first got the robot, after 3 weeks, now I am sure it won't fall down the stairs.
>Performance. It cleans kinda randomly. Don't expect it to clean your floor inch by inch, it won't. Turn it on every day, it keeps most of your house dust and hair free.
>Clean after the vacuum. super easy, the brushes are very soft, so it's easy to pick out all the hairs they collected. The dust bin is also easy to clean, I rinse it with water and it drys fast.
>Working time. About 50 minutes @ max suction. It goes back to the home station while battery is low. It doesn't go straight back though, it will get home eventually.
Conclusion. This robot is smarter than my old iRobot. Its intelligence is close to an ant. The quality is great and the seller promises a 15-month warranty. It worths the money.
