Mostly cause by poor maintainence? 6 yrs old, I have never changed tires. Supply hose seems stiff, and the bends will not come out and the lack of flexibility seems to drag the sweep where the hose limits it to go. 3/4 HP booster pump. Two problem areas, a corner it gets stuck in, and a recess in the wall that it goes back and forth in. It rarely climbs walls anymore and will tip on to two wheels. The two jets on the back are positioned center and down. ON a proper dead run it picks up sand and organic debris well.
Tail spraying of my newly cleaned windows has always been a complaint.
Does the squareness of the housing predispose to corner traps?
Is a 3 wheeled unit more nimble?
How often should one replace tires and supply hose?
The "pool kid" wants to sell me a Polaris 280? Just tell me what to buy! Can I be that honest?
I've been putting this problem off long enough by cursing, and then going outside, pulling the hose in, trying to unbend the bend in the hose and then freeing the bugger.
