This is my second robot vacuum purchase. My first was Deebot, which I thought was pretty good for the $200 I spent on it (it was a Black Friday sale last year). Well, after several months of daily work, I have a lab retriever at my house that sheds so much that he started to misbehave. One of the drive wheels got "stuck" and stopped working from time to time, I had to stop my work and reset it manually! It got boring quickly! The suction power also drops sharply for no apparent reason. So I've been wanting to buy a new one for the past few months but didn't want another Deebot (I won't go into detail as it's Coredy). wanted in the new vac-bot.1. I liked the double wide side brushes that Deebot had, Coredy has a.2. I wanted something that just vacuums, not a vacuum/mop like Deebot. This allows a larger dust collector/vacuum motor to be used. I wanted something with more suction power, Deebot was good but according to Tim Taylor's toolkit "MORE POWER!"4. In addition to more power, I wanted it to make less noise (tough compromise, but this bot does it!) where I could call a real person with real product knowledge to help me, but I didn't get that with Deebot.6 . I didn't want a Roomba! (Too expensive for what it is) So with these few things in mind I started looking for Revain to see what I could find. After about 4 or 5 different products and their reviews I came across Coredy. It had some of the highest ratings and met all 6 of my wishes, well the customer service part hasn't been used yet so I may have to go back to that! But overall I highly recommend this product. 1. Dual side brushes are great for cleaning a larger area and come with an extra set.2. Large dust bin allows you to increase the collection volume and shorten the time between emptying.3. The suction power is fantastic, there are 3 modes; low, that is 600Pa, "intelligent modeβ when the suction is low, and when it hits the carpet and needs more power, it will automatically increase to 1000Pa, and the high is 1600Pa.4. It is significantly quieter than my Deebot, even in Coredy's strong suction mode it is no louder than a box fan at medium speed. The low-speed function is surprisingly quiet.5. Again, I haven't had any problems yet, but if/when I do have any I'll report back to customer service. This is NOT a Roomba! My relatives have one that has a sweeping brush and some of the Coredy's suction and collection power. Also, they paid over $300 at Costco for their item. The only advantage they have over mine is that they can take it back whenever and for whatever reason they want to love Costco!7 . Another added benefit of this device is that it comes with a one-year limited warranty against defects not caused by you. If you're using this thing the way you're supposed to, you must be having some issues. But after my previous bot accidentally caught a wheel and lost suction, I loved the added benefit of a manufacturer's warranty. What I didn't know when I bought it, so win! In the box you get a vacuum cleaner, a charging dock, a remote control, an extra filter and a set of side brushes, and (of course) instructions. You can also download an application that will show you all the information about the bot; Battery life, suction power setting, what mode it's in, "Find My Bot" feature that finds it if it's lost, the ability to set cleaning schedules, run time and remaining life of accessories (side brushes and filter life). It was worth the money spent so far and it's about $70 cheaper than Roomba Costco! If you're looking for a great product that will give you amazing results and don't want to spend a fortune, Cordey is the place to be!
