10 Best Grout Cleaning Machines 2026 in the United States

The BISSELL ProHeat 2X Revolution Pet Pro Plus is a corded grout-cleaning machine that offers a power rating of 6.8 Amps. It's designed with TurboStrength Motor Technology, ensuring powerful yet energy-efficient suction. The machine features Dual DirtLifter PowerBrushes with 12 rows of rotating brushes, which are effective for deep cleaning and removing stubborn stains and pet odors, even those as strong as skunk odors. This makes it highly suitable for pet owners dealing with tough stains.

Additionally, it includes a hose and tool attachment, plus specific tools for pet upholstery and tough stains, enhancing its versatility for different cleaning tasks beyond just grout lines. The machine has a 1-gallon water tank, which may require frequent refilling depending on the extent of the cleaning task, but it supports both MAX Clean Mode and Express Clean Mode, the latter offering quick drying in about 30 minutes. Weighing 26.7 pounds, it might be considered a bit heavy for some users, but it is an upright model, which could ease maneuverability.

The 35-foot power cord and 8-foot hose provide extended reach, making it easier to clean larger areas without constantly changing power outlets. However, it does not have a steam function, which some users might find essential for deep grout cleaning. The machine's ability to save pets with each purchase is a notable added benefit for animal lovers. This machine is an excellent choice for those primarily looking to tackle tough stains with a reliable and powerful cleaner, especially pet owners, but it may not be the best fit for someone specifically seeking a steam cleaner for grout.

The Shark Lift-Away 5-in-1 Steam Mop is a versatile steam cleaner well-suited for grout cleaning and multiple other household tasks. It uses a 1200-watt power source plugged into standard AC outlets, providing consistent steam for sanitizing sealed hard floors and grout lines. The device includes a dedicated grout brush tool designed to reach tile gaps and tight crevices, which is essential for effective grout cleaning. Alongside this, it offers additional specialized brushes like a nylon precision brush and scraper to handle tough stains and built-up grime, making it a multi-purpose cleaner.

With a water tank capacity of about 12.85 fluid ounces, it can deliver steam for a reasonable duration, but may require refilling for larger jobs. The steam functionality includes adjustable floor modes (Light, Normal, Deep), allowing you to customize steam intensity based on dirt level, which helps avoid damage on delicate tiles or grout. Weighing 7 pounds, this steam mop is relatively lightweight and includes a detachable handheld unit, improving ergonomics and making it easier to clean vertical surfaces or upholstery.

The included double-sided washable pads add convenience and extra scrubbing power, reducing the need for harsh chemicals. The tank size might be small for extensive areas, and while the brush tools are tailored for grout, very stubborn or aged grout stains could require additional manual scrubbing. The device’s AC power source limits use to places near outlets, and some may find the water tank refills interrupt workflow. This product is a strong choice for homeowners seeking a chemical-free, versatile steam cleaner that can handle grout as well as floors, kitchen surfaces, and upholstery, balancing thorough cleaning capability with ease of use.

The Hoover Power Scrub Deluxe Carpet Cleaner Machine, also known as FH50150, offers robust features for cleaning carpets effectively. It operates on a corded electric power source which ensures consistent power without the need for recharging. The machine features an exclusive SpinScrub Technology with a 360-degree cleaning approach using multiple counter-rotating brushes. While this is excellent for deep carpet cleaning, these brushes may not be ideal for detailed grout cleaning which typically requires more precise, narrow brushes.

The water tank capacity is 3.8 liters, which is ample for large carpet areas. The addition of an 8-foot hose and upholstery tool helps reach tight areas and stairs. At 18.5 pounds, the machine is relatively lightweight for an upright shampooer, but its ergonomics are more suited for broader surfaces. It lacks a steam function, which is a key feature for effective grout cleaning.

The inclusion of a Smart Tank system makes filling and emptying hassle-free, which is beneficial for maintenance. The product includes a storage bag, a crevice tool, and a sample cleaner, adding value for general carpet and upholstery cleaning. With a two-year limited warranty, it is a reliable choice for carpet cleaning.
