Is the suction low at the tank after you disconnect the hose? If it is strong there, then the hose may be clogged. You can unhook the hose from the wands to see if you have suction or not. If you do, then look further down all the way to the brush roll. The other possible is if no clogs, check the filters, on the E series, there is a filter on the back, there is some also had one in the top and you would have to take it apart to get to it. One other is that the motor is not running at top speed and may have to be replaced. It can sound ok, but will have reduced suction. If you suspect the motor, check your owner manual, some of these newer ones had a long warr. period on the motor.

No suction


Sucked up a sock?? No seriously.. it may be as simple as that or that an on board filter is clogged. Check your manual for all filters and Hepa/screens and others. Also, is the unit making any odd noises since the non -suction scenario? Whining or screeching sounds, where is the motor impeller/vac bearing or similar is damaged or a hose is kinked within hte unit itself.. <not normally unless the unit has been taken apart and placed back together and crushed the main return vac hose. .

I have unscrewed all the screws and can't get bottom off.


Here is a possible solution. If the vacuum sounds normal when the green light comes on, then the issue is a suction bypass. Kenmore built a suction bypass in to help cool down and protect the motor should someone either never clean the filter, empty the canister or somehow manage to clog the hose. There is a spring holding the bypass closed and is overridden by vacuum suction. I guess the spring becomes weak, allowing high suction to pull it open which in turn reduces suction so it closes again. It can do this several times per second making a loud racket and slightly affecting performance until the sensor goes green, then the vacuum suction is too low to overcome the spring tension thus why it sounds fine then. The trick? The very hard way (what I did) was to open the vacuum, open the casing where the spring is and pull it apart slightly to increase the spring tension. The easy way is to put tape over the hole where the bypass is. The inlet is under the hose track on the back on the right side as you're looking at it. The hole is about the size of a quarter and you'll see fins across the hole. The tape would keep the suction. The motor would still pull back the bypass but since tape is applied, there would be nothing to reduce the suction thus keeping performance and reducing the noise. However, this circumvents the intended design so you do so only at your own risk.

Kenmore progressive 360 vacuum cleaner has low suction


Check the tube that leads down to the brush head for clogging as well as any motor or HEPA filters. If that still shows nothing, take the cover off the brush head (like you're changing the belt) and look for obstructions in there. Usually, if you have low suction on the accessory hose, the problem is with a motor filter, HEPA filter, or a clog where the hose goes into the unit. If you have good suction on the accessory hose but none on the floor, it's usually in the brush head (clog or broken belt) Good luck

Hoover Freemotion Pets 200W has lost most of it's suction!


if you take out the dirt cup at the top there should be a half moon orange that releases. inside of this half moon is a washable filter. rinse with warm water and let it dry completly before putting back into the machine. this should restore your suction. hope this helps.

No suction


have u checked all of the filters. I know that when not all the filters r clean the machine will turn on but then it will sound louder and still have no suction. Most times there is a filter under dirt container thats sits above motor and if this filter is not clean the motor cannot breath. Thus no suction

Low suction


Is the water seal in place or missing? Another cause would be a bad motor, running at a slower speed will mean low suction. If it is a motor, then you would have to replace it. Is the suction low at machine without the hose, if it is ok then may be a clog in the hose.

It sounds fine but it is sucking very little


If the suction at the port that the hose hooks into has low suction, then most likely you have a problem with the motor. Some of these Rainbow motors sound ok running, but are running at a slower speed, thus reducing the suction and replacing the motor is the solution.

Not enough suction for Panasonic MC-V5716 upright


Probably not the motor protector, its function is shut off the motor if it overheats. Most likely you have a clog or partial clog in the inlet down by the brush roll, or it is in the hose. But if the motor is running, and suction is low, with no clogs, then maybe the motor is running at a slower speed and will have to be replaced.
