Looked at the troubleshooting guide suggested on next page of forum (under "Polaris won't climb walls anymore") but it doesn't offer no-vacuuming tips. The polaris runs but will not suck anything into the bag. I notced this morning that the head float is cracked. Does anybody know if the function of the float head has any bearing on vacuuming ability or does anyone have other ideas? This Polaris is a several years old. Thanks for any ideas.
Edit: Loooked at the manual again. Does "won't back-up" mean won't vacuum or won't go backwards?
