consider the availability of consumables (new filters, brushes) on the alik they are. It would be nice to have 1 more battery as a spare. Pros below: Very interesting model price / quality. It is quiet, the sound of the motor is soft, like a turbine. The nozzle for dust mites and dirt in upholstered furniture works wonders - from a clean (about a couple of months) mattress cover, I collected a bunch of dirt, or whatever is in that composition. The nozzle for floors. Carpets works too - with a bang! from the Box it took 20 minutes to charge in normal and turbo mode (at times) It is not very heavy, as many write, but here we must proceed from the dimensions of the owner, for small fragile girls, 1.5 meters tall, he will be a bandura, and for ordinary men - completely easy. The carpet brush itself pulls forward, there is a motor. Pile lifts superbly, evenly. It is not difficult to wash it, everything is disassembled into details. The brush is removable and washable. The accumulator is removable, is charged from the power supply unit. The kit includes a stand for a vacuum cleaner and a pair of brushes, it is necessary to consider that there is a socket for charging nearby while hanging / standing. Some cons: some complain that over time the plastic bursts at the junction with the pipe, if that place becomes clogged with dust, keep these places clean. A long charge from a sluggish power supply (0.6 amperes) at 21-25 volts. There is no indicator of the remaining battery, it sits down unexpectedly, but then a couple of times it can be turned on for a while.
