Any vacuum with a spinning brushroll will get some hairwrap so my best strategy is to get a vacuum that is easy to remove the brushroll and maintain. Wider diameter brushrolls get less tight hairwrap because the circumfrence is bigger. Only vacuums without a brushroll will avoid all hairwrap but then they don't clean carpets as well. One of the problems with most Sharks is there is no way to remove the main brushroll so debris gets stuck between the brushroll, stresses the motor, and wears out the motor faster. I'd choose a LG CordZero A913BM $279, 1 battery and a charging stand. Or the LG CordZero All-in-1 Tower A931KWM $492. Both LG's have easy to clean filters, and the cyclones and brushrolls are completely removable. If I wanted a cheaper option I'd choose the Dreame Z20 $199. Just be aware the cheaper you go the shorter the batteries usually last. Really cheap batteries wear out in around 1 year, but even expensive batteries only last 2-5 years.

For all hard floors you don't need a spinning brushroll and it actually makes the vacuum noisier. I'd avoid the Bissell and most bagless vacuums because they're very loud. I agree with u/totpot, bagged canister vacuums are the quietest. No brushroll, bagged and more sound insulation make they very quiet. Like a fan on medium-high speed quiet. The Miele C1 Pure Suction $319-350 are very good for hard floors, super quiet but powerful, and they have an automatic rewinding cord. The Soniclean Whisper Jet C2 $250 is also very quiet. Good canister vacuums easily last over 10 years. If you want a cordless stick vacuum look for a vacuum with a soft brushroll. The stiffer brushroll will make noise hitting a hard floor surface and it isn't needed for smooth surfaces. The Dyson V8 is above average for cordless vacuums. Look for a model with the fluffy motor head. Downsides are cordless vacuums have a very short run time on high power like 8-12 minutes, and I don't like that you have to hold the trigger on a Dyson. The LG CordZero is a good cordless vacuum and many models come with 2 batteries and a charging stand for the same price as a Dyson. But finding a model with the soft brushroll powerhead is limited. Most better cordless vacuums have digital motors and have a high pitch that's louder than a canister vacuum, but not as loud as a bagless upright vacuum. Cordless vacuums offer convenience but their batteries wear out in 2-5 years.

I recommend cordless vacuums that have removable & replaceable batteries, easy-to-clean bins, and replacement parts available. Dysons are definitely ok, but you pay extra for the name. The Dyson V8 and V12 Detect Slim are the best vacuums with a good weight balance. I really like the LG CordZero. It has removable batteries and many models come with 2 batteries and a charging stand. I'm not confident of the dual brushroll powerhead because most dual powerheads tend to make more problems. It is getting harder to find a model with the 2 separate powerheads but that's my preference. Some of the Dreame vacuums with auto-empty bins look to be good budget values. Parts availability isn't as good as Dyson or LG but they cost less and come with a lot of accessories. If you have most or all carpets, don't forget the Hoover Onepwr Hepa Cordless Bagged Upright $189. This is a battery powered Oreck Elevate and it's great for carpets.

I don't recommend the folding tubes, they add another hose that tends to split and you can always feel a little flex when you are using it. I find extendable/retractable tubes more useful. I have an LG CordZero you need to extend the wand for regular use because retracted it's too short for regular floor use. When I'm vacuuming my stairs I retract the wand to make it easier to get closer to the stairs. A fixed tube will be the most reliable because there are no additional moving parts. I would avoid any Shark vacuums because they are unreliable and unrepairable. Also avoid the 2nd vacuum because these cheap generic vacuums tend break within a year and are also unrepairable. What's your flooring and budget?

There are vac/mops that vacuum while you mop like the Bissell Crosswave and Tineco iFloor combos. These mostly only mop and cannot dry vacuum floors, carpets, or do anything above the floor. Among the cordless vac/mops I only recommend machines with removable and replaceable batteries because the battery is such a common failure and wear item. The Hoover Onepwr Streamline and Ryobi Swift Clean are the only vac/mops that are decent and have removable batteries. The Dyson V9 with the Submarine mop attachment is a dry cordless stick vacuum good for all around vacuuming with a mop attachment. The mop attachment mops but doesn’t vacuum at the same time so you need to dry vacuum first and then mop. Vac/mops require a lot of cleanup after each use. Dyson’s submarine also is quite messy and requires a lot of cleanup after each use. Personally I would choose a decent cordless stick vacuum like a Dyson V8 or a LG CordZero and get a good manual mop like a O’Cedar Spin Mop or a good reusable spray mop. Both mop better than the Submarine and are less cleanup than a vacuum/mop. There are lots of choices. Hope that helps.

I have an LG CordZero and it’s been a pretty good cordless vacuum. Suction on low is useless, medium is ok, high is very high but you have to hold down the button for several seconds before high turns on. The LG CordZero Q3 is pretty reasonable at $299. The models that have the Kompressor lever help scrape dirt off the metal screen so you don’t have to stick your fingers into the bin. They all have an established wand too. If you buy the more expensive All-in-one models the vacuum will self empty into a bag.

I agree with flatdirection, KPA is a pretty useless number thrown around cordless vacuums. Pretty similar to HP on a shop vacuum, it makes it sound better without having to be better. For cordless vacuums it needs to have removable/replaceable batteries because they're the most likely problem area. And you want an easy to clean bin design and decent filter. Sometimes there's an LG CordZero or Samsung Jet under $200 so always look for those first. Otherwise check out the Dreame Z20 $169. It has a removable battery, multi-cyclonic, and easy to clean filters. Dreame has basic replacement parts available, battery, brushroll, and filters. Downside is customer service isn't great, but most cordless vacuum companies are giving their customer the run around. I also recommend checking out the Kenmore Intuition BU3040 (no lift-up) and BU4020 (with lift-up) both are $149. These are both small corded upright vacuums. If you want powerful suction these corded vacuums will blow away any cordless vacuum. They are as narrow as a cordless vacuum, they have swivel steering, and hepa bags that last around 2 months per bag. The 30 ft cords make them much easier to use than cheap corded vacuums that have really short cords. The BU3040 (no lift-up) is a little lighter. The BU4020 (with lift-up) is popular if you want to vacuum stairs or upholstery. Downsides are they are just average durability for the price. Corded vacuums over $200 that are bigger start to be more durable.

First a not on self empty systems. They are sort of a gimmick. Firstly, they usually can do a basic empty of the container but they are not effective at cleaning the internal filters of the stick vac, that still has to be done really regularly yourself. And many self empty systems are themselves bagless, which means you have an additional 2 or 3 filters to clean. Bringing the total maintainence burden up to 2 dust containers, 2 mesh screens, and up to 5 or 6 filters you have to clean every couple weeks yourself! In other words, they're often more trouble than they are worth. Secondly, no cordless vac is going to match the suction and durability of a corded vac. With that in mind, and if you're good with it lasting about 5ish years, here's what I'd look at. Models from LG, including their own self empty model which at least uses bags, so there's nothing to clean on the station. Dyson have a pretty poor reputation for reliability now, but if you can tolerate very poor customer support, models like the v11 are still decent. V8 is a good more budget end choice. Miele duoflex or triflex models are great choices too, better quality than the others I think with good performance, but pricy and with fairly small bin capacity. Avoid no-name or bizzarely named models on Amazon, avoid bissell, hoover, dirt devil, shark, tineco, etc.

We have an LG cord zero from 2019 and it has been great. It comes with 2 batteries and we did have to replace those, but have had zero problems.

We have had a xyz for seven years. Can still do the whole house (3brms) on a single charge. Came with two batteries whicu we alternate. Washable filters, it came with two which we wash and alternate. It's an LG Kompressor

We use the shark robot as maintainance cleaning, then have an LG kompressor for our primary cordless. It self empties, stores a lot of fur, and the battery is changeable so we can run it on high then swap to a fresh battery if it dies. It came with a mop scrub head which is a bit gimmicky but does work for spot scrubbing. It has a pet head for furniture too.

LG CordZero, has swappable batteries, some models have a dedicated dustbin on the charger, and it has a variety of tools for hard and carpeted floors. I've been using mine for 4 years now. The trigger is a bit better designed than the Dyson V7 I had before.

I have the LG CordZero - HORRIBLE!!! Always gets clogged, never can use it for more than 10 minutes without dicking around with it. I'm buying a new vac which is how I found this thread. DO NOT BUY LG!!!!

Love my CordZero too. It's so easy to maintain because the cyclone is fully washable and so are the filters. Build quality is leaps and bounds above Dyson.
