Frequently Asked Questions
How often should I vacuum my hot tub?
You should aim to vacuum your spa once a week. This prevents sediment from settling into the creases of the shell where it can create stains or harbor bacteria. If you notice a lot of leaves or sand after a windy day, pull the vacuum out sooner. Staying ahead of the mess makes the whole process much faster.
Will these vacuums work for my large swimming pool too?
Most hot tub vacuums are built for small volumes and tight spaces. They lack the flow rate and the large collection capacity needed for a full-sized swimming pool. Using a spa vacuum in a pool is like trying to mow a football field with a pair of kitchen scissors. You will spend all day working and barely make a dent in the debris.
Do I need to turn off the jets before vacuuming?
Yes, you should always shut off the circulation pumps first. The jets stir up the water and keep debris floating, which makes it nearly impossible for the vacuum to catch anything. Wait about fifteen minutes after turning the jets off. This gives the dirt enough time to settle firmly on the floor where it is easy to pick up.
Can I leave the vacuum inside the hot tub when I am done?
You should never leave a vacuum submerged when it is not in use. The chemicals in the water can degrade the plastic housing and the internal battery seals over time. Rinse the unit with fresh water after every use to remove chlorine or bromine. Store it in a dry, shaded area to keep the materials from becoming brittle.
What is the best way to deal with very fine silt?
Fine silt often slips through standard mesh bags. If your water is cloudy with dust, look for a vacuum that supports disposable filter cartridges or specialized microfiber inserts. You can also use a flocculant chemical beforehand to clump the silt together. This makes the particles larger and much easier for your vacuum filter to catch.
