Buying guide for Best window vacuum cleaners

Freshly cleaned windows can brighten a home and lift your mood. But you don’t need to scrub and strain to do it. The easiest (and most fun) way to get results is with a window vacuum cleaner, which promises sparkling clean windows and a streak-free finish every time. Just spray on your cleaning solution and let the vacuum’s squeegee head do the work. This method of cleaning is also eco-friendly because there’s no need to use rolls of paper towels to clear your windows — and you won’t be left with lint particles sticking to the glass.

From robotic window vacuum cleaners designed to automatically clean surfaces without supervision to models with extendable handles that allow users to reach up high, these devices are perfect for dwellings with many windows or homeowners who are short on time. A window vacuum cleaner is also an excellent option for pet owners whose windows get grimy and smudged with moisture from wet dog noses.

Did you know: Excess condensation can eventually lead to mold growth and leave you with an unsanitary bathroom space. Use a window vacuum cleaner to suck up condensation and prevent mold from taking up residence.

Key considerations

Types of window vacuum cleaners

  • Standard handheld: These are the size of a regular handheld vacuum but are made to suction up moisture, dust, and debris on windows without leaving smudges and streaks behind. Instead of powering a rotating brush to pick up debris, the motor works to deliver targeted suction to gobble up dirty water, so none is left behind to create a mess.

  • Telescoping: These window vacuums work the same as handheld models, but they also feature a long handle for cleaning ceiling-height windows. They’re best for short individuals who have trouble reaching nooks and crannies at the top of windows or for those who wish to prevent back strain.

  • Robotic: With a hands-free robotic unit, there’s no upper-body workout required to get streak-free clear-view windows. Fill the device with a cleaning solution, press a button, and leave it to do its job. The drawback? These types of vacuums are costly, and despite their promise to provide supervision-free cleaning, some models may require some babysitting.

Water tank

The water tank on a window vacuum cleaner is meant to store sucked up condensation and cleaning solution. The tank should be large enough so that you don’t have to empty it halfway through cleaning. Tanks typically range from 100 milliliters to 300 milliliters in capacity, but larger units may have bigger tanks.

Window height

Tall windows that usually require you to get up on a ladder are no match for a vacuum with a telescoping handle. With a longer handle, there’s no need to strain and struggle to clean those out-of-reach tight corners. If your home has many large windows, a vacuum with a longer runtime is best.

Nozzle shape and size

The nozzle on a window vacuum cleaner doubles as a squeegee and vacuum. As you squeegee your windows, the vacuum sucks away water and other debris into its tank. The size of the nozzle is an important consideration. A nozzle that’s very narrow is excellent for cleaning small windows like those in a bathroom or on a door. If you’re cleaning a large living room window, however, opt for a unit with swappable nozzle heads or a wide nozzle. Match the nozzle size to the window, and you’ll get done cleaning a lot faster.

Weight of unit

Bulky vacuum cleaners are a pain to wash windows with. Choose a model that you can comfortably hold for as long as you need.

Indoor and outdoor use

Most window vacuum cleaners are fine for outdoor use — just don’t leave them out there. If you’re in the market for a robot window cleaner designed expressly for outdoor use, check that it’s outdoor-friendly before making your purchase.

Expert Tip



Often, window vacuum cleaners are sold in kit form and include accessories such as a spray bottle, microfiber pads to help wipe away messes, and swappable cleaning heads for different-sized windows.

Power source

Window vacuum cleaners are typically powered by a rechargeable battery, so they have a limited runtime but are designed to clean up glass surfaces quickly and efficiently. Charging is typically done via an AC power adapter.

Extendable handle

A telescoping handle allows you to clean hard-to-reach windows. Check the listed measurements to ensure that your chosen unit will allow you to reach your whole window without you having to stand on your tiptoes.


Runtime ranges from 20 minutes up to 45 minutes. The more windows you have to clean, the longer the runtime required.

Charging time

Charging time ranges from device to device, but quick charging is ideal if you want to tackle multiple windows in one shot.

Window vacuum cleaner prices

Compared to cheaper models, more expensive units tend to run longer and allow for the cleaning of multiple windows in a single sitting. Window vacuum cleaners sold as a kit come with all the accessories you’ll need and are often on the premium end of the pricing scale, which ranges between $50 and $100. The most expensive options are robotic models, which will set you back well over $100.


  • Window vacuum cleaners aren’t just for cleaning your windows. Use one to wash your shower door, mirrors, or even your bathroom tiles, too.

  • You can also use one to remove condensation from bathroom areas.

  • Make sure your unit is charged before starting a cleaning job.

  • Time to wash your windows? If your kit came with a detergent, dilute the solution with water in a spray bottle. Otherwise, use a store-bought glass cleaner for best results.

  • Spray cleaning solution over the entire window, and spread it with a cloth (microfiber is best).

  • Clean in a downward motion with your window vacuum cleaner.

Handheld window vacuum cleaners are also an excellent tool for helping to clean your car.


Q. Can I use any type of cleaner with my window vacuum?

A. Glass cleaner is the best type of cleaner to use on windows to prevent streaking. Some kits may include cleaning solution, but once that’s finished, you can buy whichever glass cleaner brand you prefer.

Q. What’s the advantage of a robotic window vacuum cleaner?

A. Robot models are hands-free so your arm won’t get tired from holding the device and, in most cases, it’s OK to walk away and focus on other tasks while the vacuum cleans.

Q. Are all window cleaning vacuums sold in kit form?

A. No. A few brands offer window vacuums without all the accessories. Kit-free units are usually cheaper.
