I would have given 5 stars for everything on the unit, but lack of parts have just totally disgusted me. I have always loved Dirt DeviI, I buy cheaper units and replace them every five years. Bought this unit about 2 maybe 3 years ago. I have cats and dogs, and foster additional ones from time to time= tons of litter, dust, hair, and dirt carried in from outside. vacuum cat trees, couches, laminate,tile, appliances, counters, everywhere! Also doing animal transport I frequently must vacuum car. I vacuum almost everyday. The only problem I have had is that the carrying handle s/b on the top, and there are minimal replacement parts. Nothing has malfunctioned, but we unfortunately put the hose near the furnace and it melted the hose. We taped the hose back together but this has caused many blockages, and we have given up using it. The hose is not an available part, and I have been looking for a long time. I no longer can find another canister that does not have handle at the end of hose that is as "slim" which can be used in countless areas such as a floor register. The handle at end of hose is very comfortable not having an extra handle piece, it puts very little stress on my wrists which I have carpal tunnel. Using accessories has been quick and I don't have to stop and have a production to change the pieces. Never had a problem with the suction,rewind cord, or accessories. My unit would stop after vacuuming certain items, i just stopped and removed them. I'm very disappointed that all parts are not available.
