I bought this vacuum to replace a former 3001 SE model had run its course (a little over 20 years if I'm not mistaken). It's perfect depending injector / extractor, I have not tested in single vacuum cleaner, I use a different in these cases. Perfect cleaning hard floors. At home, there is the Roman travertine (full of holes where the earth brought by animals accumulates), after the passage of the craft, it is white and clean. For those who want to use a product in cleaning water, I give them the stuff I use: laundry S * M * int rc pine resin, on a one tablespoon diluted in hot water for complete filling of the tank with clean water. It does not foam, and it cleans very well. After a teen party, where the orange juice and the rest was a bit knocked around, trampled and stuck with dirt (we go, we go out ...) day after the cleaning was a facility disconcerting. The house has regained its dapper rapidemment. Obviously, some people find that the dump dirty water is difficult because you have to disconnect the hoses to empty the reception bin, but found instead that much progress had been created in relation to the former model. As for wheels, excellent handling (too well, it rolls itself).
In short, I recommend this purchase. Besides the delivery was fast and free as very often.
