The Dirt Devil I lay me after a few months robot abstinence (following an old iRobot Roomba). The scope of supply is functional and includes instrument and the power supply a set of spare brushes. About a charging station the Spider does not. The device is portable, quickly assembled and looks quite chic. On the device to different cleaning settings via a slide button on the bottom side can be adjusted. At the top are light diodes that give ua Aukunft on the charging status and show and when the dust container is full. Freshly charged, I let go of the Spider to our upper floor: Mainly parquet / tiles, but 3 small rugs in the hallway a staircase. A positive feature is that the device is very quiet on the road compared to the Roomba and really careful driving against obstacles damage is not expected. Since the Spider does not brush roll (how many competing products), it sucks through a relatively small opening in the dirt, to replace the side brush to the desired position. On smooth floors and with "normal" dirt works pretty good- but you have pets and, accordingly, pet hair on the floor cleaning clogged opening quickly. On carpets the Spider moves up and sucks though even there, but here is the lack of brush as a shortcoming. The cleaning performance I find unsatisfactory on carpets. Since the Spider has no station that it hits, you should keep an eye on gross, where he is, so you when the battery is empty it can easily pick up the end of the cleaning process or. The dust container you have to actually (at least) empty after each cleaning. This is very simple and is done fix. When cleaning the missing roller brush is then quite nice because you do not have it remove hair etc. consuming. Dust bin emptied and is waiting the Spider on the next use. My conclusion: for small apartments with excessive accumulation of dirt (read: possible no pets) and smooth surfaces may be worth the Spider, especially as he brings an appropriate price-performance ratio. For us (House, Pets, both hard floors and carpets) it was not the right tool, we have taken a little deeper into their pockets and bought us a Deebot.
