powerful as I wanted

good good quality product, the power is to go, and finally a table vacuum worthy the name.
Why did I choose ??
This is my third or fourth table vacuum cleaner, but other lower power 3.6 V or 4.8 V gave just satisfaction above all made the soul after about two years, the problem of rechargeable batteries (very often the source of reliability problems, do not support a permanent load) the magazine.
I chose this model.
1 for its 10.8 volts
2 Li-ion batteries (for me decisive in my choice)
3 because the load will stop when the batteries are charged
4 for the brand

The only I can say in ment is battery life but I trust to those below to know the other devices
