Question about Hoover UH70210 Bagless Upright Vacuum

Open Question

Hoover UH70210 is overheating and has poor suction

We ran the vacuum for a little while with some clogs in the hose. All clogs should be gone, though there may be a small amount remaining between the entrance behind the brush and the hose coupler. I cleaned all the clogs I could find, washed the rinsible filter. I'm not sure what else I can do. Any advice would be welcome.

    Ok. The clog was in the non-flexible neck bit that's connected to the hose and the canister. I thought I'd cleared that out, but apparently, I didn't. I was following juststink's instructions and a some sand was kicked loose, but nothing else. I think all the turning over and banging around of the vacuum must've loosened up that last bit. When I turned the vacuum on again, it started overheating for a second. Then, there was a "thunk" noise, and suddenly the vacuum stopped overheating. It was honestly like a magic trick. My canister went from empty to 2/3 full instantly!

There should be a bottom plate covering the brush roll that you can remove, if you can't dig out the what is in there, try using your hose and suck it out from the bottom, maybe you will be able to get it out.

SOURCE: Decreased hose suction with Windtunnel

There are very few things left to check. First verify that the filter is installed properly, in the dirt cup. second check to make sure the dirt cup lid is on and secure. Did you use water on the round dirt cup filter? if you have you will need to replace it. To verify this remove the round filter and re-install the dirt cup on the vac. do not vacuum the carpet, just turn it on to check for proper suction. and then turn it off.

Your problem has nothing to do with it in the upright position. once turned on you will always have suction, either to the floor or when hose is removed from foot for accessories.

SOURCE: No Suction

The water channel hose could be torn. you can check by removing the lower tank and tilting it backwards, it is located in the lower section. could also be the filter cover. it is needed for full suction control.

SOURCE: I have full suction with the hose and when the

So I have exactly the opposite problem, it sucks in floor mode but the hand held has zero suction. My daughter and i just spent the last hour disassembling and diagnosing and found this: The way the suction tube is configured, you have two places to **** from, the floor and the hand held hose. If you look at the back of the machine, you can see the "y" where the two hoses join. just behind the beater bar there is a blast gate that closes when you stand the machine upright. This closes the blast gate and directs full sution to the hand hose. In floor mode as the handle tips back, a follower wheel and spring move the blast gate to open. THIS IS THE IMPORTANT PART...if the hose is not docked, there is a second place for the suction to go and you will get no suction at the floor. In my case, the center post where the spring mounts is broken and the blast gate flap does not close, so the hand hose gets no suction because it is like a straw with a hole in it, the air will seek the least resistance. In your case you either have not returned the hose to the docking port or your blast gate is stuck in the closed position. To check this remove the two screws and clamp that secure the lower hose to the suction manifold. Pull the hose stright an look inside to see if the blast gate is open or closed. Use the release pedal to cycle the machine between upright and floor mode and you should see the blast gate open and close. If you don't, well that's a whole other story. I'm off to see if I can find a replacement part at repairclinic.com. If not I will have to get some polyester epoxy and fix it myself.

Hoover has poor suction


Do you have a clog in the hose or where the hose meets the internal parts of the Hoover? Also, have you bothered to change the bag. My husband doesn't think of changing bags or filters. Hoover is a good product.

IF you can use a broom stick to run through the hose to make sure that there is nothing in it, then you need to check the output filters. They get plugged up with fine dust particles and the suction is reduced. The output filters can usually be rinsed out.

Hoover tc5238 bagless cylinder vacuum cleaner - no suction


You have a clogged hose. Sometimes a Q-tip or something like that gets sucked up and then stuff jams up against it. You can use a long stiff wire with a hook bent in the end to reach the jam and work it loose. Just be very careful not to poke the wire through the hose! Work slowly and get the clog out a bit at a time.

The clogged hose would also account for the red light.

I have little suction when using the hose attachment


Check the hose for a blockage. If you remove the hose, if there is suction at the point where the hose hooks to the back of the vac, then the hose is clogged. If no suction there, check filters, make sure they are clean.

Poor suction-need to know how to remove & clean filter under canister of Hoover Wind Tunnel Mach 4.7 Twin Chamber System.


I assume this is a Hoover Bagless, if poor suction, the hose or dirt inlet by the brush roll may have a clog. The filter inside the dirt container may need replacement. Some had a screw to take out to remove the cover for the filter, the one under where hte dirt container sits. Alos the belt may be stretch and won't turn the brush roll under load. Having the model number would help.
