Complaints in reviews I read mentioned this sweeper does not work well in long bladed grasses. My lawn is thick and I maintain the blades at 3". This sweeper works really well on it and I believe any problems are caused by improper adjustment. If the brushes are too low it does try to pull at the grass, stopping forward progress. I find I have to adjust the sweeper separately for the lawn, gravel walkways and concrete patio area. Once done, it works very well. In fact, it so well it could really use a larger hopper bag. When the poplars really drop I cannot go very far until the bag fills. I recommend.
