Don't put too much stock in positive feedback. The vacuum cleaner has two modes of operation: the first, normal, gives the impression that it is functioning, and the second, turbo, vacuums more or less as effectively as the normal mode, but it only runs for a maximum of ten minutes at a time, which is insufficient for cleaning a studio apartment. When the correct nozzle is used on a smooth floor, the vacuum cleaner will go back and forth to pick up debris, but it will not lift the debris. The exhaust from the engine collects all of the fine dust and hair that has been in the air for a considerable amount of time. It will not be worth the cost. Suitable for tasks such as cleaning up food that has been spilt after children, etc. Avoid using this method when cleaning apartments.
