SHARK Pet Performance Plus Upright

I can only talk about 2 shark models: the UV900 and the NV552 since I have owned both. This is my story I had the NV552 for 6 years and it was fantastic. I have 3 English Bulldogs who shed like crazy. I have to vacuum at least 3 times a week. And the NV552 was a suction monster. I kept the filters clean and changed the brush roller and belt every year (the UV900 you cant change the brush roller only the soft roller in front that is a huge negative because brush rollers wear out in 2 to 3 years so when the brush roller wears out you have to buy a new vacuum SERIOUS PLEASE CHECK NOT LYING) That right there should make you run from this vacuum especially how much it cost. BUT there is more. So after 6 years my NV552 went down the front motor that turns the roller was shot. I could have easily bought a replacement it is an easy fix. (you cant replace the motor in the UV900 SERIOUS PLEASE CHECK NOT LYING) So got on Amazon looking for the part and came across the UV900 and was amazed look at all the gidgets and gadgets it even had a built in air freshner to freshin the carpet (doesn't do S*^$ cant smell nothing) I was sold. When the UV900 came it was like X-MAS (not much gets an old 53 year man exited, yes ladies vacuuming is my thing my wife is not allowed to touch the vacuum only in case of an emergency) Got it all set up, kicked the dogs out, LETS ROCK, I am thinking "This is going blow away that old piece of junk NV552. Flipped the switch AND could already tell not as much power BUT I am thinking "its new tech maybe it does not need alot of power but sucks like know one biz". So start in the living room after about 5 min I KNEW this is a piece of JUNK. It hardly picked up ANYTHING now I havent vacuumed for close to a week waiting for the UV900 so there should be alot of dirt and especially dog hair. I do the whole house. I almost cried it was that bad. With the NV552 I had to dump the canister at least 2 times sometimes 3 (and the NV552 canister is bigger than the UV900) The UV900 canister was barely half full after vacuuming the whole house. So got on the net and did some digging this is what I found. 1. POWER the UV900 has a 960 watt motor the NV552 has a 1200 watt motor doesnt seem like a huge diff but trust me it is. That is suction POWER PEOPLE and anyone who says watts dont matter (on a shark vacuum) has no clue. 2. REPLACEMENT PARTS. The UV900 good luck shark has made its newer vacuums so you cant work on them. They want you to buy a new vacuum every 2 to 4 years NOT LYING check it out on youtube. The NV552 you can fix almost anything on the vacuum. 3. The UV900 is meant for hardwood floors and high pile carpets. But still would not buy the NV552 is still better on those surfaces. 4. AND PRICE go compare the cost of a UV900 to a NV552 that and what I have told you should be enough NOT to buy the UV900 So packed up the UV900 and sent it back. I ended up buying a new bottom half for my NV552 (almost the same price as just the motor but still WAYYY cheaper than the UV900) When it came kicked the dogs out and HOLY COW 5 FULL canisters of dirt and dog hair. What ever shark you buy the 2 most important things you need to look at #1 Can you replace the parts like the brush roller or a motor if you cant dont buy that model# POWER after finding #1 look at the watts on the models (you can find the watts on shark website) Get the highest watts possible. And dont fall for the gidgets and gagets like the soft roller brush in the front or the carpet freshner dispenser. POWER MEANS MORE SUCTION and that is what you want in a vacuum.
