Tenergy Otis Robot Vacuum Cleaner

I do not use this as my primary source of cleaning the house. It is used for edges and light touch up on hard wood floors with rugs. I cleaned the floors with the regular vac and use this one daily to keep up with a shedding dog. It eats dog hair, lego and anything smaller than a nerf bullet left on the ground. It will not remove dog hair from a rug that has been stepped into the fibers but will keep your house clean if you use it daily for touching up. It is really handy around the wood stove where bark falls off. Keep an eye on it if your stove is hot. It cleans the crumbs off the kitchen floor and does a nice job of sucking up and sweeping over the dog hair that floats into the corners. Maintenance is easy. Remove the dirt caddy and sweep out the junk. Tap the air filter a few times and re-install. Keep an eye on your brush, you can easily remove it with the two bottom tabs and then lift up on the rubber grommet side. Carefully pull up the rubber grommet and remove any hair that wraps round the brush. Sweeper arms will also get a little tangled with hair after several uses. Pop them off and remove string or hair. Front free wheel pops out easy with a flat head and you can clean the wheel up in seconds. Keeping the unit maintained and clean really helps the performance of the machine. IT will work ok if you just dump the trash caddy, but it will work great if you maintain the robot. Keep an eye on stuff that can be knocked over and rare lego parts. This unit will man handle things to get around the corners. I have knocked plants off of stands that were not really secure to begin with. I also search the bin for lego and anything else of value that may have been swept up. I found a sapphire pendant last week. :( For the money, this little robot is a good deal. It's simple to use and maintain. It does a great job of keeping the house looking good. I doubt you could put it in a dirty house and expect it to magically clean your floors. I like running this unit and taking care of it. It's my first robot vac. I was skeptical because my friend purchased an 800 dollar robot and killed it in a week. He put it on a dirty cabin floor and did not maintain it. I think the point of these is to keep your house floors maintained, not to clean a dirty floor that has been neglected. If this ones craps out I will let you know and purchase another one simply because it has already paid for itself in time savings.
