What's the best way to clean an in ground spa? I have a pool sweep (the pool cleaner) but it obviously won't work in the spa so I get lots of pebbles and debris on the bottom. I've tried draining the spa but I can only drain to the bench which doesn't take care of the debris on the bottom. Battery operated pool vac? Someone told me I could extend my pool sweep hose and remove the sweep and just use the hose on the bottom of the spa?
Thanks in advance
