I must say, of all battery suckers that I had previously, this is the best!
You put on the device, it can be loaded (The charger can be mounted on the wall) and can then get started. For me, the suction time was even a little over 9 minutes.
First, I'd like to mention that with the battery. It is a Li-Ion battery (each phone), this has a low self-discharge and is easier to handle than the other models with a NiMH battery. NiMH batteries lose partial discharges (Short turn on, absorb and turn off after one minute) faster their maximum Energiekapazietät and life!
Especially great is the auto shut off the charging station when the battery is fully charged. Here one must not wait until the battery is fully charged after 12 hours to him then to take time out of the charging station so that the battery can not be overcharged.
The vacuum cleaner has two power settings and the filter is also very easy to clean. He absorbs everything, Basalt Split, small stones, plant debris bishin to dog hair (after repeated over it eyes). By the time you open the device and the filter takes out, you can see the dust and the dust bunnies that there are in the carpet.
But it can not replace completely a vacuum cleaner!
Conclusion: A top device is a must in every household ;-).
