Work well. ### ⭐⭐⭐⭐ This is huge! *by J***Y on May 8, 2025* It works but this thing is huge and heavy. Wish I bought the little Robbin Air one. Inexpensive but massive in size. Probably better than harbor freight, maybe not. ### ⭐⭐⭐⭐⭐ Great vacuum pump *by A***G on June 4, 2021* I have been using these pumps for many years, they work great to get down to a deep vacuum. I use multiple of these vacuums with 1/2 vacuum hoses on one system. Pulls down to 500 microns before you know it. I use mine for a year and then retire them with a new one, and at the price point it is worth it. The pumps still work after a year and you can flip the apex seals in the pump to get longer life out of them. ## Frequently Bought Together - Mastercool 6 CFM Single Stage Vacuum Pump 90066-B - Mastercool 98210-A Electronic Refrigerant Scale, Black - Mastercool 69110 Automotive A/C Recovery System – SAE J2810 Certified, 30 lb DOT Tank, 1/2 HP Oil-Less Compressor, Automatic Shut-Off, Compatible with R134a, R12, R22, R410A --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/42972353-mastercool-6-cfm-single-stage-vacuum-pump-90066-b](https://www.desertcart.pl/products/42972353-mastercool-6-cfm-single-stage-vacuum-pump-90066-b) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-11*
