The pump is better than me, she sucks good at even if a little air in the intake line is. Even small leaves residues and pebbles are not a problem. Only the supplied suction hose is of poor quality. When unpacking a lot to me that it is very rigid and strong. I then hung him for a month in the warm boiler room so that it is softer. Without Success. Then I put it in the sun. If you try a little careful to bend him now just as he broke through in two places. Once in the middle and then to the screw to the pump. Cheaper plastic crap. The hardware store I bought my confidence with a better hose and the right VA fittings, since the return time was expired!
