The Pool Blaster Max Li CG makes sense for an owner who wants a cordless vacuum for deliberate floor, step, and spot cleanup without connecting a suction hose. Its 13-inch head covers more floor than a small spa vacuum, while two included filter bags let the buyer match the bag to the debris. The trade is that this is still a manually guided tool, and the telescopic pole is not included.
This is a researched buyer analysis. Smart Pool Care did not buy, charge, submerge, time, weigh, or compare this vacuum. We reconciled Water Tech’s current SKU 31000KL product page, operator documentation, support and parts records with current independent category coverage. Manufacturer runtime is a design claim, not a measured result from our pool.
Check pole reach and usable depth together
The 13-inch head width answers how broad a pass can be; it does not answer whether the operator can guide it to the debris. Sketch the reachable floor areas from safe standing positions, the step widths, and any fittings that block a straight pass. Include the pole connection and the manual’s operating-depth requirement in that assessment.
The stated 14.25-inch minimum operating depth at a 45-degree angle matters for shallow ledges. Do not assume the smaller nozzle removes that motor-submersion requirement. Ask Water Tech about the exact configuration if a tanning shelf or step is shallower than the published condition.
For a broad floor with a few tight corners, decide whether changing attachments is acceptable. For mostly narrow steps, paying for the larger head may add little useful coverage. The nominal 13-inch width is not a measured cleaning swath, and overlapping passes reduce any theoretical area-per-pass calculation.
Include the separately purchased pole in total cost and storage length. The vacuum is a fit only when the complete tool can be guided and retrieved according to the instructions, not merely when the motor unit fits in a cupboard.
Quick fit matrix
| Your cleanup job | Max Li CG fit | Why |
|---|---|---|
| Sand or silt in a few floor areas | Good candidate | Xtreme multilayer bag is included |
| Leaves, twigs, and acorns already on the floor | Good candidate | Wider head and all-purpose bag suit bulk pickup |
| Whole-pool cleaning with no owner guidance | Poor fit | It is manual, not robotic |
| Stairs and targeted misses after a robot cycle | Strong use case | Cordless spot cleaning is the point |
| Very shallow ledges | Check first | Water Tech lists a 14.25-inch minimum operating depth at a 45-degree angle |
| Surface leaves | Wrong stage of cleanup | Use a net or surface skimmer before debris sinks |
What the CG model actually includes
Water Tech identifies the current Max Li CG as SKU 31000KL. The package includes a 13-inch vacuum head with soft-bristle brush, wall charger, reusable Xtreme multilayer filter bag, reusable all-purpose filter bag, corner crevice nozzle, and scrubbing brushes. A standard telescopic pool pole can attach to the unit, but the pole is sold separately.
The distinction matters because “Pool Blaster Max” names several nearby products. The current standard Max Li Gen 2 is SKU 30160ML, while the CG page specifies SKU 31000KL and the 13-inch head. Marketplace titles can compress those names. Confirm the SKU, head, filters, charger, and generation rather than ordering from the photo alone.

Head width is useful only when access matches
The 13-inch head favors open floor area. A wider pass can reduce repeated tracking across a rectangular pool, and the soft-bristle head provides some agitation while the vacuum collects loosened debris. Water Tech lists the assembled unit at 23.5 by 12.75 by 7 inches and 5.65 pounds.
That same width can be awkward around narrow steps, tight curves, ladders, drains, and fittings. The corner nozzle helps with targeted access, but changing attachments adds a handling step. Sketch the areas that actually collect debris before deciding that the largest head is automatically the best one.
Match the filter bag to the debris
The all-purpose bag and Xtreme multilayer bag are not redundant. The all-purpose bag is the logical starting point for leaves and larger pieces because it prioritizes capacity and flow. The multilayer bag is intended for finer material such as sand and silt.
Fine filtration increases resistance as material accumulates. A pool with a large leaf load may be faster to clear in two stages: remove leaves with a manual deep pool net first, then use the vacuum and finer bag on settled grit. That sequence is our editorial workflow judgment, not a measured performance claim.
Empty and rinse the selected bag after use according to the manual. Inspect it for tears, seat it correctly, and let the machine and charging interface dry as directed. A clogged or poorly fitted bag can reduce useful pickup even when the motor is operating normally.
Battery and charging are the ownership burden
Water Tech says the rechargeable lithium-ion system is designed for up to 60 minutes per charge. Actual useful time can vary with battery condition, debris load, filter resistance, storage, and operating technique. Treat the stated figure as a ceiling for planning, not a guarantee that one charge will finish every pool.
The support instructions say the unit must be completely dry before charging. The P30 adapter aligns by arrows and clips into place rather than twisting. Charging and dry storage require a suitable location away from pool water and chemical fumes.
Water Tech lists a one-year limited warranty for the Max Li CG’s electronic components. Its current parts catalog also lists compatible bags, brushes, wheels, vacuum heads, chargers, and a replacement motor box. Availability today does not guarantee every part will remain stocked, but the documented parts route is a useful ownership advantage.
What it does not replace
The Max Li CG does not navigate, climb, or start itself. The owner must guide it by hand or pole, overlap passes, watch the bag load, retrieve it, clean it, and recharge it. For autonomous floor cleaning, the Dolphin E10 and Aiper Scuba E1 comparison covers a different buying decision. Owners of an E10 that misses fine floor sediment can check the official fine and ultra-fine basket part numbers before adding another motorized cleaner.
It also cannot correct water balance, filter trouble, algae growth, or circulation faults. Vacuuming removes collectible debris. It does not explain why material returned or why water is cloudy.
Reasons not to buy
Skip the Max Li CG if you expect unattended cleaning, need wall or waterline coverage, lack a compatible pole, or have mostly surface debris. A smaller handheld model may suit spas and tight ledges better. A pool with heavy daily floor accumulation may justify a robotic or suction cleaner instead of repeated manual passes.
The CG is also hard to justify when a current cleaner already covers the floor and rarely misses spots. Buying a second motorized tool adds charging, drying, filter cleaning, battery aging, and storage.
Final recommendation
Buy the Pool Blaster Max Li CG when the job is clear: hose-free manual cleanup across open floor areas, plus steps and spots that another system misses. The 13-inch head and two included bags create a useful debris workflow, but only for someone willing to steer, empty, rinse, dry, and charge the tool.
Verify SKU 31000KL and the complete package. If the listing omits the pole, that matches Water Tech’s current product record; budget and size the pole separately.
