Bissell produces battery powered Crosswave wet dry vacuums as well as corded Crosswave models.

Just like the corded series, there are also several cordless models available. Below we will discuss the main difference between these Bissell Crosswave Cordless, Cordless Max, Cordless Max Deluxe, X7 Cordless models.

There are:
• Bissell Crosswave Cordless 2551

The Crosswave Cordless Max models (2554,2554A,2590,2596) and Deluxe (2593) are the same machine except for what are included and the color. The 2596 is exclusive to Bissell, it offers some limited time free bonus and one extra year warranty.

The Crosswave Cordless(2551) is a bit different from the Max models. Besides some cosmetic differences, such as the tanks, upper handle and carry handle, there are some other differences that might affect your buying decisions.

The Bissell CrossWave X7 Cordless is the newly added series of the Crosswave cordless series.
When compared to the Max models, the main difference is that it adds the TURBO PET™ Mode to boost cleaning performance, especially for tackling pet mess and stuck-on messes; another new feature is the LED headlight. The X7 adds the LED headlights on the nozzle to illuminate dark spots and find hidden debris.
The CrossWave X7 is a bit lighter than the Max.

The HF3 has some big changes, it does not have a solution spray trigger on the handle like the previous models. Instead, it automatically dispenses cleaning solution onto the floor during use. Meanwhile, it does not have an Area Rug Mode and a Hard Floor Mode, but features a Water Spray Rate Selection Button that allows you to switch between High and Low water flow.
It has No Turbo Pet mode, no LED headlights, no WiFi support.

• Digital Display
  The Max, X7, HF3 models have some lighted icons that make cleaning more intuitive:
  modes indicator to tell you which mode you select – Hard Floor or Area Rug (Max and X7) or TURBO PET™ Mode (X7 models), High or Low Water Spray Rate (HF3).
  dirty water tank full indicator will blink orange or flash red when tank is full.
  wifi connection status icon (Max and certain X7 models).

  The X7 and HF3 models have some more indicators:
  X7 has Error Indicator, Fan Error Indicator, and Clean Out Cycle Indicator. HF3 has Error Indicator, and Brush Roll Obstruction indicator.

  The Crosswave cordless does not have these indicators.

• WIFI supported
  The Crosswave cordless does not support wifi.

  The Max supports wifi connection, you will need to use your smart phone to install the Bissell Connect App to connect the machine, and it will provide helpful alerts, maintenance tracking and usage tips. However, you can use the vacuum without the App.

  Some CrossWave X7 models, such as CrossWave X7 Cordless Pet Pro 3011, does not support WiFi whereas some models, such as CrossWave X7 Cordless Pet Pro 3279, have WiFi built in.
  In fact, the WiFi Connectivity is not an important feature when using these wet dry vacuum.

• Self Cleaning
  All feature Clean Out Cycle to flush clean water through the machine for quick and simple clean out. However, there is difference between this process. The Max, X7, HF3 models use solution from the clean water tank whereas the Crosswave cordless models use water from the docking tray.

• Control Buttons
  The Max, X7, HF3 have a Power button to turn on/off the vacuum and a Mode button to switch between modes.
  The Crosswave cordless has a HARD FLOOR button and a RUG button, you press one of them to turn on the vacuum, press the button again will turn it off.

• Edge Cleaning
  According to Bissell, when compared to the Crosswave cordless, the Max has improved edge cleaning to pick up dust, pet hair, debris that gathers along baseboards and in corners.
• Cleaning Path Width
