Bissell 1950F Wet Pick Up Vacuum Cleaner

Dear Schonaldo, Thank you indeed for your reply. I phoned Bissel to locate a service centre close by as I did not have the expertise to do any repairs. The Bissel call centre referred me to their in-house service people who confirmed your finding that the machine is gravity fed, however they also suggested that sometimes there is a problem because of an air lock. Their suggested solution was to fill the tank and depress the trigger a few times and, if this did not work, to hold the trigger down for a period. It took me a day or so to get back to the machine and it could have been that the air lock was dispelled by time, however, when I re-filled the tank and depressed the trigger everything started working again. I wonder also whether I may have put too much cleaner solution into the tank, which may could have further exacerbated an airlock situation. Alternatively, I notice that the air vent at the top of the tank is very small and I have inserted a needle to open it up a little, thereby creating more pressure. Anyway hoorah - everything is working OK.

I have the the same problem.. Took machine entirely apart. Inspected the actuator lever, rod, plunger, hose, bar (entire water feed components). Took the tank apart and determined there was a possibility that the curved hose(inside of tank at suction side) could have sucked itself onto the bottom of tank. Modified to prevent this from happening again. Put the machine back together and voila! It worked for a few minutes only if I kept the trigger depressed. I believe the machine was designed for part gravity water feed and part vacuum water feed. Whatever the case, not working too well. Although, I did notice it works better when the clean water tank is full. After inspecting and testing I determined that there is too much vacuum energy being lost to the underside of the brush housing hence not creating enough suction for on demand water supply.
