Shark Rocket PowerHead (AH452) is strong and durable floor vacuum cleaner. It is often described as combination of upright and stick vacuum cleaner, but personally, it looks more like robust carpet/floor sweeper. But, it is much more than that.

Shark Rocket PowerHead AH452 Features and Specifications

[amazon box=”B00EUKHACW”]

Shark AH452 is designed for cleaning both hard floors and carpeted areas.

It comes with 2 interchangeable brushrolls: a Deep Cleaning All Surface brushroll and a Gentle Touch Hard Floor brushroll. Brushrolls access is via so-called ‘Brushroll Garage’. Both brushrolls are removable and rinsable.

Note that a Deep Cleaning All Surface brushroll is suitable for carpets (high and low speed) and bare floors (low speed), so that the user doesn’t have to change the brushrolls with every surface change. Also, a Gentle Touch Hard Floor brushroll can be used on both carpets and bare floors using both speed settings, just its cleaning effect on carpeted surfaces will not be as good as cleaning of the Deep Cleaning All Surface brushroll.

While one of the brushrolls is in the unit, other brushroll can be stored in onboard brushroll storage holster.

Shark AH452 is powered using 600 W motor. Thanks to the design, suction motor is very close to the brushroll and the cleaning nozzle, with very low energy losses due to the air flow passing through the unit.

Dust cup is of pop-up design and can be quickly removed for faster cleaning.

To help with easier storage and for easier use, telescoping wand has several possible positions. Note: when the unit is turned on, suction motors starts right away, but the brushrolls will not spin, until the wand with the handle is not pulled back and down.

LED headlights help the user with cleaning in low light conditions. LED lights are very important in the units with such low profile, since they are easily pushed under the furniture, beds and other similar objects and where spotting of the dirt and other smaller and even larger objects would be hard without LED headlights.

Shark AH452 weighs 9 pounds, and perhaps could be lighter. However, 8 pounds of the unit is close to the floor, resting on wheels. Swivel steering combined with such design means that Shark 452 can easily access floor areas that are sometimes hard to reach for full size uprights and even stick vacuums.

However, Shark AH452 comes without other cleaning attachments and without flexible cleaning hose – such design is suitable for cleaning of the floors and other similar flat surfaces. This unit is not suitable for cleaning upholstery, furniture and similar elevated surfaces.

Due to design constrains, Shark AH452 doesn’t have automatic power cord rewind system. But, it comes with very respectable 30 feet (~9.1 m) long power cord. Such long power cord and 10.6 inches (~27 cm) wide cleaning path enables the user to quickly clean large area without changing wall power outlet.


Unit controls are on the handle and are very simple – 2 speed settings for optimized fast and slow brushroll spin. It is good to know that vacuuming thick carpets and area rugs with constant, strong suction can cause difficulties in moving unit back and forward. To avoid such issues, suction itself can be decreased using a suction release valve on the cleaner powerhead itself. When the slid is open, it reduces the suction of the unit and thus reduces the force that is required to push/pull unit around. Nice and important feature, but personally, I would prefer electronic suction regulation.

Shark AH452 is very easy to use unit, just be sure to read manual/instructions that come with it – it explains several specifics of the AH452 vacuum cleaner. Better safe than sorry…

Unit dimensions: 44.9” tall x 12.6” deep x 12.2” wide (114 cm tall x 32 cm deep x 31 cm wide).

Air filtration is done using pre- and post-motor mechanical (foam, felt) filters. Shark AH452 doesn’t have HEPA grade air filtration, but nonetheless, air filtration is good. After first use, filters can change the color, but they are washable and are design to last the lifetime of the vacuum. Should something happen to the filters, replacements can be easily ordered online.

Warranty: Shark AH452 comes with 5 years limited warranty – much longer warranty period when compared with the similar units.
