What to know before buying

Listing details to confirm

Compatibility claims differ across listing sections: one names G30 SES and G30 Hybrid SES, while another names only G35+, G40+ and G40 Hybrid and also states that several LR30 and L35 models will not work. Confirm the exact vacuum model and selected listing before buying. The product dimensions and Plastic material are listing-level details, and the 99.7% particle-capture figure is a manufacturer claim, not an independently verified result.

Less suited to

The supplied evidence contains aggregate ratings but no written customer feedback, so it does not establish specific praised features or reported problems. The ratings lean favourable but include a notable one-star portion, and the small sample limits what can be inferred. For buyers, feedback cannot settle the key practical question of compatibility, which the listing describes inconsistently.

Frequently asked questions

Which vacuum models does the listing say this kit fits?

The compatibility claims are inconsistent. One section lists G35+, G40+, G40 Hybrid, G30 SES and G30 Hybrid SES, while the description names G35+, G40+ and G40 Hybrid. Check your vacuum's model number and confirm compatibility with the selected listing.

What parts are listed in the kit?

The listing specifies six dust bags, four side brushes, one roller brush and one brush guard.

Are the dust bags reusable?

No. The listing describes the parts as disposable and identifies the bags as disposal dust bags.

Does the listing claim the dust bags filter fine particles?

Yes. It claims a four-layer filter system can capture 99.7% of ultrafine particles. This is a manufacturer claim, not an independently verified performance result.
