I rarely write reviews, especially negative ones. However, I feel the need to let everyone know how bad this thing is. Out of the box it works great and looks pretty impressive. After a few days of repeated use, it's showing signs of performance issues, with the main issue being loss of suction. It won't pick up larger items like dog food pellets (smaller pieces). The damper in the suction chamber starts to stick after use. No matter if you clean it, it will still get dirty with dust and clumps, so whatever you just vacuumed will drop the riser on the floor. his suffering.
