I took it so as not to spoil expensive home vacuum cleaners with construction dust during small home improvements. It perfectly collects traces of children's creativity. Good for vacuuming the car. Pros below: Norm power. Nozzles for dust removal for a perforator work out with a bang. The AEG wall nozzle and stays on. Door for quick dumping of debris. The dust container is conveniently separated and disembled for cleaning. From 3 and 4 Ah batteries works for a long time. Got cons: The hose is short - a native extension cord under the order. Noisy. It's a bit heavy - with a 4 Ah procor, it's not always convenient to hold. With a simple PCB at 3 Ah, the optimal balance.
