I inherited a pool with my new home and it's been a sharp learning curve. Most things have been fairly straightforward and with the help of forum members here, it's been a great help.
With the pool, came a mechanical pool cleaner called a Hydrosweep ( seen here for sale on the Oz eBay site) http://cgi.ebay.com.au/NEW-QUESTA-MA...3A1|240%3A1308
After about 6 months of use it stopped working and I took it to the local pool shop and they sent it the authorised repairer and it was supposedly overhauled for a cost of $200.00. Repair was guaranteed for 3 months. 7 months later same problem. Not under guarantee sent back. Repair cost 160.00. Decided to purchase a brand new one ($329.00) and keep the repaired one as spare. 4 weeks after purchasing the new one the power roller mechanism failed and this time I contacted the distributor personally and explained my frustration. It was repaired under warranty and returned to service. 13 months later exactly the same problem as the original unit has occured ( which is: it loses drive and amongst other things requires the replacement of the "long shaft"). Back to the repairer for a repair, thankfully under warranty. It's still at the repairer.
I realise this is a mouthful but to complete the picture: pool chemistry is perfect (water is tested by the another pool shop I have started using every 4 weeks or so), skimmer basket and filter baskets are cleaned every weekend, filter back-washed and rinsed according to the pressure guage, which with the sweeper working sits in the blue zone at just under 50, leaf litter is just average depending on wind conditions, dust or silt build up (airborne) is again average depending on wind conditions. The cleaner runs an average of 24 hours per week. The cleaner is adjusted as per the manufacturers guidelines so that the drive wheel turns an average 0f 22-24 turns per minute
I no longer have any faith in this type of cleaner for my application any longer and would like some advice on what type of cleaner would suit my needs. Cost is not as important as long term reliability. I've had a look at all the "Kreepy Krauly" style cleaners but really don't know where to start.
