MY RECOMMENDATION TO YOU IS TO STOP SELLING THIS PRODUCT !!!! ITS KINDA HARD TO USE WHEN THE WHEELS KEEP FALLING OFF !!!!!! EUREKA HAS ALREADY SENT ME A REPLACEMENT PART AND 6 MONTHS LATER THERE FALLING OFF AGAIN... I WOULD HAVE NEVER ORDERED FILTERS FROM AMAZON IF I HAD KNOWN THE WHEELS WHERE GONNA FAIL AGAIN !!! SIGNED I AM VACUUMLESS !!!!!!Eureka 437AZ Optima Lightweight Upright Vacuum
