If it wasn't for the tank leak, I would have given it 5 stars. For the money this is a decent machine. I use a large homemade triple layer microfiber bag. But a large volume has a drawback - a smell appears, so it is better to use bags, 5-6 liters, and wash regularly. In order not to raise dust through blowing, I adapted a sewer plastic outlet, 50/45º, directed upwards. Additional nozzles, I buy from other manufacturers - much cheaper.
