After using it to clean up construction project, I cleaned the tank, filter and cleared the hose, but I have lost good suction.

If your Bissell Little Green Machine has no suction at the hose end but good suction underneath the dirty water tank, try these steps: check for clogs in the hose and attachment, ensure the tank and filters are properly seated, test without an attachment, inspect for damaged hoses or seals, clean the machine, and run hot water through the hose. If the issue persists, contact Bissell customer support for assistance or consult your user manual for specific troubleshooting steps.

If the loss of suction occurred during wet vac,the float has blocked the discharge vent , and this can be cleared by unplugging vac and emptying tank. if you tip the unit over while running it will close exhaust vent and can be cleared by turning unit off and wait 1 minute and restart unit.The most common causes of loss of suction are dirty filters or a clog in the hose. To troubleshoot, remove the hose from the vacuum, place your hand at the opening of the tank inlet and turn the vac on.
If you feel suction at the inlet, the issue is with your hose or accessories. Check your hose and accessories for a clog. If no clogs are found, check the hose for a hole or crack - even a small crack can cause a loss of suction. If a crack or hole is found, replace the hose.
If you do not feel suction at the inlet, turn the vacuum off and unplug from the outlet. Follow the steps in the user manual that came with the vac to clean the filter. Check the filter for rips or tears; replace with a new filter if any are found. Empty the tank or if you are using a collection bag replace it if it's full. Make sure the filters are properly installed then secure the housing to the tank. Plug the cord into the outlet, turn the unit on and place your hand at the tank inlet to check for suction. If you still do not feel suction at the inlet, turn the vacuum off and unplug from the outlet. Check the tank for any cracks and make sure the drain cap, if applicable, is secured to the tank.

Check the hose for obstrution

I think you mean it's an 8955, Riccar has not had a 8995 model. If there is no suction in the hose it has to have something clogging it. Open the little round opening on the back of the vacuum where the hose attaches to see if you have suction there.

All filters need to be replaced eventually. How soon depends on use and how often it is cleaned. If the suction is good when you removed the filter it indicates you need new filters

Hi, Have you checked and made sure the floor plate is secure and tight without any gaps around the edges? If that's ok then check the suction hose where it bends down to the floor unit,, lots of times dirt,hair and stuff collects there when the filter was plugged up. remove the floor plate ( like you were going to change the belt ) and use a wire coat hanger to run up the suction hose and back out and clean out any debris, also check the entire hose for blockage ( top to bottom ). if this is all clear and you still have little suction - then the problem could be the vacume motor itself

9 times out of 10 there is a hose blockage at the point where the hose bends down to the floor. remove the suction hose and clean and clear any dirt build up inside the hose. also at this point it is a good idea to clean the filter. ( remove and brush out or use a air compressor to blow filter clean ).

When you use the shop vac for cleaning up water you must remove the filter.

The filter is for dust particles not for water
I would replace your filter and dump the water out from the shop vac, Also after each time you vacuum up water dump it out of shop vac.

I hope this helped you happy new year!

At the top of your wand, do you have a plastic swivel that cover a hole in the wand? This is for when you are cleaning curtains, and if that is open, or cracked you will loose suction there... also check your hose for cracks, or breaks. If it were in the shop I would put a gauge on it... normal suction is about 80-95 inches of water lift at the end of the hose. Once you have check each section of the hose, and wand, check the housing for cracks, a missing gasket (Very Good Reason For Lack Of Suction) As to your Filter, how long have you used that one filter, you can clean them for a while, but once a paper filter gets full of FINE dust you won't get it all out, you will have to replace the filter itself at that point. I hope this was helpful.

if the blower is much stronger than the suction, you may have an air leakwhere the cover fits on tank or possibly a warped tank or cover. feel all around the unit for air being drawn in somewhere besides the hose. try it without the hose on and block the inlet for a couple seconds to see if the unit leaks air in. also replace the filter , dont try to clean it, the pores clog and reduce suction and damage motor.
