Milwaukee M18 Backpack Vacuum Review - 2.5years look back
2-1/2 years ago we reviewed the Milwaukee cordless backpack vacuum. Back then we were impressed with its adaptive design, and backpack ability, providing users with a vacuum that can tackle a wide array of clean-up tasks.
On Board Accessory Storage
We used it to clean drywall dust, thin-set crumbs, concrete dust, wood shavings, sand, dried mud and other common job-site messes. It does a good job at medium to small sized debris. We still recommend using a shop vac for major demo debris.
Emptying the Vacuum Bin
The vacuum canister is clear and allows full visibility to the user. The canister has a capacity of 1-gallon and features an easy-empty, bag-less design. What I mean by this is the debris bin can be emptied in seconds at touch of button.
There are three major PLUSES to having a bag-less vacuum:
1. Cheap - you won’t have to spend any money on purchasing replacement dust-bags
2. Visibility - clear canister exterior lets you see exactly what you’re picking up which could be particularly handy for making sure you don’t accidentally suck up valuable small objects
3. Easy to maintain - thanks to the visibility you’ll be able to easily see when the canister is full and in need of emptying
The negative to not having a bag, is you will need to tap off, vacuum or replace your HEPA filter more often.
The vacuum works off of cyclonic technology, one thing we noticed on this vacuum was the number of rubber seals it has, at the debris canister, and filter section. These seals are the "secret sauce" that allows the vac to maintain is cyclonic-action and maintain suction-efficiency. Leaks and losing seal, are the biggest killers to CFM and vacuum efficiency.
So did we get this review right?Yes we did! Here’s our thoughts looking-back
Suction Improvements
The vacuum uses a HEPA filter with 99.97% efficiency at .3 microns.
This vacuum was designed for and can handle drywall dust, concrete dust, wood/metal shavings, in our original review we noted that the vacuum suction is OK, not great. That’s still true today.
What I mean by that is the vacuum will not pick up larger chunks of drywall or small 1-1/4" drywall screws.The most important improvement Milwaukee can make to this tool is to give it corded shop-vac suction.
Longer Hose:
The vacuum hose is an accordion-style hose and stretches from 18" to 6-feet with no negative effects. Most vacuum hoses are unwieldy, but this one bends nicely and retracts to its original position nicely. Kinks are a major failure of vac hoses, over time, and this hose was designed to avoid that.But we feel that when NOT attached to your back you want the longer hose and MORE suction. Milwaukee does offers a longer 9-foot hose as a accessory.I see this as a MUST if you’re going to be working off of a ladder, staging, lift or MRO type repair cart and not wearing the vacuum on your back.
Floor Sweep
The floor sweep attachment has an integrated rubber squeegee which I found pushed or pulled sawdust backwards and left a small pile behind.
This necessitates the user having to go back over the pile. The purpose of this rubber sweep is to keep the suction intact but when going over large quantities of dust you may have to make two or more sweeps to catch it all. Once we figured this out we adjusted and planned for it.
Milwaukee did optimize the floor sweep design by raising the housing, 2-3 mm inward, near the wheels. This was done to give better clearance [preventing a log jam] as sawdust and other debris entered the hose orifice. This vacuum has been optimized for hard surfaces but still works well on tight weave carpets
Brush Attachment Needed
Additionally the vac needs a brush attachment would be helpful for cleaning dust of baseboards, trim, windows, radiator fins and other intricate non-floor surfaces. Something we typically would use this for.
Let’s talk about the 3-in1 feature. We NEVER use it.
Weight and Maneuver-ability
Backpack Vacuum weighs 15.3-pounds as a bare tool. Adding as 9 Ah battery adds 2.5 lbs and a 12 Ah battery 3.5 lbs. It is easily carried on your back, and maneuverable.
One learning point, we noted, when wearing this as a backpack was to be spatially cognizant of hitting finished work with the protruding canister protruding from your back. This is especially true when working around finished trim, walls, or cabinets.
We Recommend Buying this! Because a vacuum cleaner is no good if it’s a pain to use, empty, loud to operate or difficult to maneuver it’s important to me that this Milwaukee cordless vacuum is none of these.
It’s convenient to use, quiet, easy to empty and most importantly it’s runtime performance is decent for an 18 volt cordless tool.
It is especially useful for doing quick spot cleans. Not being tethered to a cord means cleaning takes less time and is easier to use on stairs.
