Query: Died after a year and a half

Loved this vacuum for the first three months, then I was constantly washing/changing filters (and the HEPA filter can't be washed, you have to buy a new one every time). The suction stopped completely one day, so we tried to fix it following the instruction manual. Good luck with that! Nothing worked the way it was supposed to, so we've finally given up and will be purchasing a new vacuum - but not a Bissell.
