I be look for a new vacuum cleaner and after read the review for the Dison I be afraid to purchase a product that be more talk than performance . the s7210 be comparable in price to the Dison but have very few bad review . one that I notice be not be able to find vacuum bag for it . Amazon sell they all day so that be not really a problem . the s7 be extremely powerful and extremely quiet . it move and turn easily and the control be all located and design to make operate it easy . we have a bagless vacumm cleaner before this and we still have to change certain filter and deal with the container of waste be always messy and seem to leave you in a cloud of dust . this be why we decide to go back to bag . I highly recommend this vacuum cleaner . my advice be to get hardwood floor but if you must have carpet then it be better to buy one vacuum cleaner that will do the job correctly and last a long time . \*\* warning \*\* this be a powerful vacuum cleaner design for carpet not area rug . if you have some small area rug this maybe too much vacuum cleaner for you . PS . the wand be also excellent at remove dust from you heat register .
