3 in1 Automatic Robot Wireless Vacuum Cleaner | sweeping robot

The product code is different: ES27 vs. LS07. The only difference I see are the brushes with 4 tips instead of 6.
This is a dumb sweeping robot, not a smart one. It keeps going (sometimes straight but usually deviating to the left) until bumps. Then tries for about 3 seconds to go to the left and if it can´t, goes back about 30 cm turn 45º (almost always to the left) and resumes. Depending on the shape of the room, it keeps cleaning on the same path over and over again without passing for the dirty places even once. I got bored watching this stupid thing for about 15 min, power it off and switched to another room.
The manual says you must recharge the unit when the lamp turns red. I kept looking at the cleaner but it never changed the indicator to red. It stayed at blue all the time until died. Suming up the two rooms I can say it lasted for about 40 min. from fully charged.
The cleaning mop is rectangular shaped and is "unsecured" to the robot by 3 square shaped velcros. I firstly thought the cleaner found something while working, but it was just the mop dropped out.
As soon as you grab it in your hands, you realize it´s from the cheap league. It is very light. But from a distance it looks good.
When operating it is noisy and may be good to remind you to watch where you walk.
Mine came with grease stains in one of the brush places.
The box was smashed while shipping as usual. It has a plastic handle which I liked (I don´t know why), but it would be more useful in the unit itself instead.
The vaccum power will suffice to catch some dust and lint.
I could recommend this buy if it would have the mop fixed better and with a bigger battery. Or if you dare to deal with these 2 things.
