Manual vacuums give you the most control and work on every pool type. They require more effort but are the most thorough option — especially for vinyl liner pools where you need to be careful with suction and sharp edges.
Designed specifically for vinyl — wide flat bottom distributes suction evenly without concentrating it in one spot. Soft rubber wheels won't scratch or snag the liner. This is what you want for any vinyl liner pool.
✓ Vinyl⚠ Not for concrete
Pros
Safe on vinyl liner
Even suction distribution
Lightweight and easy to maneuver
Cons
Won't work well on textured concrete
Requires manual effort
Curved profile follows the contour of fiberglass shells and gunite surfaces. Harder wheels and brush strips on the bottom help agitate dirt off the surface as you vacuum. Do not use on vinyl — the brushes and hard edges can snag and tear.
✓ Fiberglass✓ Concrete⚠ Not for vinyl
Pros
Follows curved pool contours
Agitates embedded dirt
Cons
Can damage vinyl liner
Heavier than vinyl heads
Always prime your vacuum hose before connecting. See our
Troubleshooting Guide for the full step-by-step priming process. A hose full of air will break pump suction and leave debris on the bottom.
Automatic cleaners save time but not all of them work on all pool types. Choosing the wrong cleaner for your pool surface is one of the most common and costly mistakes pool owners make.
Runs off your existing pump — attaches to the skimmer or a dedicated suction port. Moves randomly around the pool vacuuming debris into your filter. Budget-friendly and effective for light debris. Works well on vinyl liner pools with a flat-bottom cleaner head.
✓ Vinyl✓ Fiberglass✓ Concrete
Pros
Affordable — no separate pump
Easy to install and remove
Good for light debris
Cons
Adds load to your pump
Sends debris to filter — more backwashing
Random path — can miss spots
Uses the return pressure from your pump — or a dedicated booster pump — to move around and collect debris into its own bag. Keeps debris out of your filter. Works well on most surface types but check that the cleaner head is rated for your surface.
✓ Fiberglass✓ Concrete✓ Vinyl w/ right head
Pros
Collects debris in its own bag
Doesn't clog your filter
Works on heavy debris
Cons
More expensive
May need booster pump
Bag requires emptying
Completely independent from your pool's plumbing — just drop it in and plug it in. Has its own motor, filter, and programmed cleaning path. Most thorough automatic option. Excellent for fiberglass and concrete. Use only soft-brush robotic models on vinyl liner pools.
✓ Fiberglass✓ Concrete✓ Vinyl — soft brush only
Pros
Most thorough cleaning
No load on pool pump
Cleans walls and floor
Programmable schedules
Cons
Most expensive option
Must remove when pool is in use
Wrong model can damage vinyl
Dolphin is the most widely recommended robotic cleaner for residential inground pools. Models like the Dolphin Nautilus CC Plus and E10 are reliable, energy efficient, and have replaceable fine filter cartridges. For vinyl pools, confirm the model has a soft brush roller, not a PVC blade brush.
✓ Fiberglass✓ Concrete✓ Vinyl — check model
Pros
Industry leading reliability
Easy cartridge filter cleaning
Energy efficient — under $20/yr to run
Cons
$500–$1,200 depending on model
Not all models safe for vinyl
⚠ Vinyl liner warning. Never use a robotic or automatic cleaner with PVC blade brushes or hard plastic scrubbing edges on a vinyl liner pool. These will scuff, scratch, and eventually tear the liner. Always verify the cleaner is rated for vinyl before purchasing.
Brushing your pool walls and floor weekly prevents algae from taking hold. The right brush matters — using the wrong one can scratch fiberglass, tear vinyl, or be too soft to do anything on concrete.
Nylon bristle brush only
Soft nylon bristles clean effectively without scratching or snagging the liner. Never use a stainless steel or wire brush on vinyl — even light contact can puncture or tear.
✓ 18" nylon wall brush
✓ Soft corner brush for steps and coves
✕ Never wire or stainless bristles
Nylon bristle brush — no metal
Fiberglass surfaces are durable but can be scratched by metal bristles, which also voids most fiberglass warranties. Nylon brushes clean the surface and remove algae without damage.
✓ 18" nylon wall brush
✓ Curved brush for contoured walls
✕ Never wire or metal bristles
Stainless steel or combination brush
Concrete is rough and porous — nylon alone won't cut it for algae embedded in the texture. Stainless steel or combination (nylon + stainless) brushes are appropriate and effective.
✓ Stainless steel bristle brush
✓ Combination nylon/stainless
✓ Algae brush for heavy buildup
Brush weekly even if the pool looks clean. Algae starts as a microscopic film before you can see it. Weekly brushing disrupts that film before it becomes a visible problem — especially in corners, steps, and behind ladders where circulation is poor.
The most basic and most used tools in pool maintenance. Every pool owner should have both a flat skimmer net and a deep bag net.
Flat fine-mesh net for skimming leaves, bugs, and debris off the water surface before it sinks. Use daily during heavy leaf fall. Works on all pool types — just don't drag the frame along a vinyl liner.
✓ All pool types
Pros
Fast and easy surface cleaning
Prevents debris from sinking and staining
Deep mesh bag attached to a frame — scoops sunken leaves, acorns, and heavy debris off the bottom without a vacuum. Essential after heavy rain or wind. Before vacuuming heavy debris, use a deep bag net to remove the bulk first — it'll save your filter.
✓ All pool types
Pros
Removes bulk debris before vacuuming
Saves your filter from clogging
Cons
Can stir up fine debris
Slower than vacuuming

Works on all surfaces |
- Remove bulk debris with a deep bag net before vacuuming — especially after storms. It prevents your filter from clogging mid-vacuum.
- Always vacuum to WASTE after opening the pool in spring. The first vacuum of the season is always the dirtiest — don't send that through your filter sand.
- Brush the pool before you vacuum, not after. Brushing stirs up debris that then settles — vacuum once it settles back down.
- On a vinyl liner pool, never vacuum in one spot for more than a few seconds. Concentrated suction in one place can stretch or dimple the liner.
- Clean your skimmer basket and pump basket every week — a clogged basket reduces flow, which starves your salt cell, reduces filter efficiency, and can trigger heater error codes.
- After heavy rainstorms, test your water before you do anything else. Rain dilutes everything and can drop your pH and alkalinity significantly.
- Brush steps and corners every week. These low-circulation areas are where algae almost always starts — not in the open water.
- If you're using a robotic cleaner, remove it from the pool when swimmers are in the water and when you're shocking. Chlorine concentrations during shocking can degrade the rubber components over time.
